Fratelli Pagani (CEV) 1930 catalog page of pocket flashlights

Welcome. Most European-made mopeds have high quality C.E.V. electrical components, made in Italy since the 1920’s by Fratelli Pagani (Pagani Brothers). C.E.V. is a trade mark that stands for Costruzioni Elettromeccaniche Venegonesi. English translation: Constructions Electromechanical of the Venegonese people (from Venegono, Province of Varese, Northern Italy). CEV is now part of ZADI.

ZADI was founded in 1962 by Antonio Zavatti and Enrico Diacci, two former employees of Magneti Marelli. ZADI made all of Piaggio’s locks, and most 1960’s and later Italian motorcycle locks. In the 1997 ZADI purchased GKS (formerly Neiman, maker of fork locks) and other companies, forming ZADIGROUP. In 2001, ZADI purchased the electrical giant CEV, and has since become a world leader in manufacturing motorcycle and vehicle lock sets, lights, instruments, odometers, switches and electronic solutions, such as automatic parking systems.

Aprilia (Italy) made lights and switches for many 1960’s – 70’s Italian, and some non-Italian, motorcycles and mopeds. This greyhound logo appeared on a 1972 Ducati 750GT head light. This Aprilia, an electrical equipment maker, is possibly from the industrial town of Aprilia, near Rome. The famous Aprilia motorcycle make is completely different.

Merit Werke (Germany) made switches for German mopeds, and for Puch, Peugeot, and others. Merit Werke Gmbh began in 1966, in Germany then later moved to Malta, in the Mediterranean. They still make automotive switches and components, with the same MW logo, but with the name Merit Malta.

ULO (Germany) made tail lights, reflectors, and turn signals for German mopeds, Hercules (Sachs), Kreidler, Solo, Kynast, and tail lights for many non-German mopeds, Batavus, Sparta, Puch, Peugeot, Motobecane and Honda PA50. ULO was founded by Moritz Ullman in 1947 in Geislingen Germany. Ullman knew how to make molded glass products, like bicycle reflectors.

Luxor (France) made head lights for French mopeds, Peugeot and Motobecane. Luxor has been making quality bicycle lights for about a century. Before electric lamps were “invented” in the 1910’s, Luxor made carbide lamps. In Europe the Luxor Motobecane head light is square. USA-model Motobecanes have a 4.5″ round sealed beam housed in a Luxor ring and bucket.

HR (Slovenia) stands for Hidria Rotomatika, a division of Hidria. Tomos (mopeds), Iskra (moped magnetos), and AET (moped electronics) are also divisions of Hidria. Along with many automotive and industrial products, Hidria Rotomatika made high quality controls and switches for Volocci (electric) and Tomos mopeds, 1992 to 2007. The HR switches are nicknamed “blue button” in the Myrons Wiring Diagrams, because they are part of a sequence useful for identification: TOMOS SWITCHES: 1986-91 had only “black button” CEV, 1992-07 had mostly “blue button” HR, 2002-07 also had “yellow button” Domino, and 2008-13 had only “red button” TBS.

The Hidria Rotomatika controls are referred to here as “1992-2007 Tomos” controls. The only HR logo is on the right switch, barely visible. The “1992-07 Tomos” controls say “TOMOS” on each black plastic lever blade, but say nothing else.

Domino (Italy) is well known for making controls. Since the 1970’s in the US, and before that in Europe, Domino made controls for about 90% of all Italian mopeds, and for about 30% of all European mopeds. They are still going. In the 2000’s Domino also made switches, used on 2002-07 Tomos Revival, Arrow, Arrow-R and Streetmate.

TBS (India?) makes modern motorcycle and scooter controls. Their control levers, throttle, and both switch assemblies all have awesome quality and function and resist breaking. The TBS switches are nicknamed “red horn button” in the Myrons Wiring Diagrams. TBS controls (Domino compatible) are on 2008-13 Tomos mopeds, all models.

Peterson (USA) made tail lights, and head lights for 1970’s American-made mopeds, like AMF and Murray. Peterson began in 1945 making automotive tail lights. They still produce head lights, tail lights, and other automotive items in their huge Grandview, Missouri plant.

Niox (Germany) made head lights for many 1960’s German cars, such as Mercedes Benz, and motorcycles such as Zundapp and Hercules. On 1970’s US mopeds, a NIOX 4.5″ round head light in a ULO housing was original on 1978-81 Puch Magnum. NIOX square headlights were on 1984-86 Puch Maxi Sport LS, Maxi Sport LS II, Cobra, Cobra II, and Austro Daimler. ULO-housed NIOX round headlights were also on some German moped makes like Solo (Odyssey in US). Every other German, Austrian, or Dutch moped had a CEV headlight.

Saturnus (Slovenia) made lamps and reflectors for European cars from the 1950’s on. They began in 1921 making tin cans. Saturnus made lights for Tomos mopeds from 1988 to 2012. Their rectangular head light and rectangular signal light assemblies are similar to and interchangeble with CEV lights, but the individual parts are not. Unlike CEV, Saturnus lights lack the US DOT certification. So most USA version Tomos mopeds have CEV lights. Saturnus is now part of Hella (Slovenia).

Rinder head light

CEV head light

Rinder (Spain) made head lights for Derbi mopeds and motorcycles. Spain had high import taxes to encourage the use of domestic components. That’s why some Derbi parts are Spanish-made-under-license, like the Walker (VDO) speedometer and the Arbeo (Dellorto) carburetor. The Rinder square-hexagon moped head light would have been on the US models, but it did not have DOT approval. That’s why the Derbi Laguna fairing has the “incorrect” shaped CEV round head light. In Europe, the Sport Coppa motorcycle and the 1970’s -early 80’s Derbi Variant mopeds, all had the “correct” square-hexagon Rinder head lights. By the late 1980’s Rinder had a rounded rectangular headlight approved by US DOT, used on the Derbi Variant Sport and DS50.

Stanley (Japan) made head, tail, and turn lights for vintage Hondas. Koito (Japan) made headlights. Denso (Japan) made some Honda electrics. Kokusan (Japan) made electrics. Tatung made Taiwan moped speedometers.

The Czech moped, Jawa, has it’s own components.

Comparison of moped and bicycle cable ends.

E4a pear ∅3.9/6 x 9 use E5s
E4b barrel ∅7.0 x 7.0
E4c inline ∅4.0 x 5.0

These bicycle cable ends are listed here to show how much different they are from motorcycle cable ends. A bicycle gear cable 4mm end could be ground down to become a motorcycle throttle cable 3mm end. A bicycle brake cable road type interchanges with a motorcycle pear or mushroom type. A bicycle brake MTB type 7mm end fits loosely into a 8 or 9mm motorcycle brake lever, but functions OK.

The above step ferrules all fit loosely over the cable conduit. The end cap type ferrules below fit tight on the conduit, or are crimped on by special pliers. The end caps are supposed to fit tight, for several reasons: For strength and cable performance, to help keep out dirt and water (thus increasing lifetime), and for easier servicing. Unlike the step ferrules, which are necessary, the end cap ferrules are not necessary. Sometimes conduits need to be cut and the end cap ferrule needs to be left off. The conduit will still function good without end caps, as long as the adjuster or other stop piece hole, usually 2.5mm, is not too big. Without a 6mm OD end cap ferrule, a 5mm conduit will eventually slip through an improper stop piece hole, like 4mm instead of 2.5mm. But as long as the holes in the end pieces are the proper size, the cable does not need end cap ferrules.

5. Bulk Items

B1-B6: Bulk Inner Wire

Sometimes very long cables are needed, for long bikes, or very tall handlebars, or for other things that use mechanical control cables. For 1.2mm and 1.6mm thick inner wires, up to 8 feet, it is better to use bicycle wires. beacuse they already have end(s) and cost less. The same quality 5mm conduit (housing) for bicycles costs much less than for motorcycles, and comes in colors. For thicker or longer cables, the bulk motorcycle wire and black conduit is the only choice.

2. Ci.Te. Controls

Ci.Te. is an Italian moped lever used on 1960’s and early 1970’s Italian mopeds. They are similar to 1970’s Domino levers. You can see that in the side-by-side comparisons below. Domino blades have the D9 special stepped tube 6mm ID, that snaps into the 8mm pivot hole, to spread out the load over a large area. Ci.Te. levers are more primitive in that the blades rub on the pivot bolt in just two places, and so the pivot bolt gets cut by the sharp edge of the folded sheet metal. Domino levers also have assist springs, but Ci.Te. levers do not. Ci.Te. controls have no facility for mounting brake light switches. Ci.Te. lever blades do not have balls on the end. These last two things are required on USA mopeds. So therefore Ci.Te. levers are rare in the USA. Out of almost 1000 moped levers, new and used, mostly Magura and Domino, there was only one Ci.Te. lever blade. That is how rare they are in Southern California 1970’s -1990’s 20 moped shops leftover parts inventories plus 100’s of local mopeds turned into parts.

3. OSL Controls

O.S.L. levers are heavy duty and high quality Italian controls, used on some mid to late 1980’s US model mopeds including Safari, Benvenuti, and Cosmo (Colt). They look like Domino, except for the kink in the middle of the lever. Myrons does not have any OSL controls or levers for sale. They were (almost) never on any mopeds sold in California. Out of a thousand moped levers at MM, this is the only OSL sample.

4. P.V. Controls

P.V. is an Italian moped lever, used on Benelli, Guzzi, Intramotor Gloria, Testi, Rizzato and other Italian mopeds. None of the parts interchange with Domino. The lever blades are all black plastic, as are the throttle twist tubes. The housings are cast aluminum. The housings break easily when the bike falls over. Instead of a pivot bolt they have a press-in 6mm roll pin.

5. TS Controls

TS vintage Italian controls are uncommon. They appear to be Domino compatible.

TS throttle control

6. Derbi Controls

Derbi brake levers $21 each

Pre-1987 Derbi mopeds had their own brake levers, made by Derbi, and throttles and grips made by Ideale. From 1987-90 they had Domino Italian made controls.

Brake Levers

The brake lever mounts were welded to the handlebar. So there is no changing controls without changing handlebars or grinding off the original lever perches/housings. Changing handlebars is difficult because the original Derbi handlebars also do not interchange with the rest of the world, because they have special mounts welded onto them.

Pre-1980 had black plastic brake levers, and post-1980 had black metal ones. The aftermarket metal brake levers, made by Vmotoparts, replace both the 70’s plastic and the 80’s metal levers.

Decompression Lever

The original black plastic 1976-1986 Derbi Rabasa decomp levers are scarce or not available. However there is a pretty good substitute available. A late 1980’s Domino choke lever, like on the later 86-89 Derbi Variant Sport, can be modified to fit an earlier Derbi.

1, Domino choke original
2. Substitute for Derbi
3. Derbi decomp original

Decomp levers bottom:
Domino choke mods –
widen pivot hole to 6mm
round off upper “corners”

Substitute lever #2

Substitute lever pulled in

The substitute Derbi decomp lever can be ordered for $12 plus $5 for the modification.

Compared to a universal small clamp-on lever, the benefits of the Domino choke modified lever are:

1. No need to modify the original cable. (With a BMX bicycle lever, the sleeve stop hole is wider. The cable must be cut to insert a wider stop piece. But then the inner wire must be replaced to get the length lost by cutting back, and then a small 5 x 8mm pinch bolt soldered on properly. More difficult.)

2. No need to grind off the welded-on mount. No interference with the lights/horn switch.

3. Goes in the original position, looks proper. The word “choke” wipes off with carb spray solvent.

7. Universal Controls

These are the universal throttles and levers:

1. Magura throttle

2. Generic throttle control with grips

3. Generic brake levers

1. $20.0 #26-mag Magura universal throttle, no grips, uses a P5 pinch bolt cable end 5.5 x 8 mm
1. $20.0 #26-mag fits an installed throttle cable with 28 mm upper exposed length, as shown
2. $15.0 #26-0321 generic throttle w/hard plastic grips, uses a P5 pinch bolt cable end 5.5 x 8 mm
3. $18.0 #12106 pair of generic bicycle brake levers, uses a bicycle type ∅7 cable end

Magura was founded in 1893 by inventor Gustav Magenwirth as a manufacturer of gasoline motors, hydraulic press pumps and water pressure devices. Since 1923 in Bad Urach, Germany, they have produced handlebars and handlebar controls for mopeds and motorcycles. They are an industry leader, and still produce handlebar controls for all major makes. Since the 1970s, the company has also made many products for the bicycle industry. The name Magura is from Magenwirth and Urach. The logo is from a rotary rack developed in 1930.

Left 80’s, right 70’s

Wrap-around and Slide-type: There are two main types, wrap around where the throttle cable wire wraps around and attaches to the twist tube, and slide type where the throttle cable attaches to a block that slides in a spiral slot in the twist tube.

70’s and 80’s: It is a subtle difference, but side by side you can see there are two different folded aluminum original Magura levers. The 1980’s “late” right lever, on the left, is longer and straighter than the 1970’s “early” left lever, on the right. When they are not side by side, it is really hard to notice.

All of these levers interchange and are 12mm wide at the pivot.
Original levers have a 6 mm top hole and a 5 mm bottom hole.
Some bottoms are the same as tops, others have a cable slot.
Flipping (using a right lever on the left side or visa versa):
Right and left interchange when flipped (bottom becomes top).
If the lever is flipped the pivot bolt must also be flipped, unless
the 5 hole is drilled to 6 and the 6/5 pivot bolt changed to 6/6.

Magura Moped Controls

Sears Allstate left control

Magura “Open Wrap Around” silver controls are used on 1950’s and 1960’s Puch, Tomos, Sears Allstate, and many others. Some are cast aluminum levers, and some are folded sheet aluminum.

Most of these did not have threaded holes for brake light switches.

Ball-end levers began in the 1970’s, for safety.

Left black housing,
both start cable and

Magura “Open Wrap Around” black controls were on 1980’s Euro models, but not on US models.

Like the other Magura wrap around throttle controls, the twist tube has a groove that locks onto a tab in the housing. The two are locked together first, then slid onto the handlebar. Once on the handlebar they cannot become separated.

These have a plain hole with bottom, for the brake cable. Most do not have a hole for the a brake light switch.

Peugeot or Not Peugeot: There are two ways to stop the brake cables. The Peugeot way is to have 6mm threaded bottomless holes in the housings with 6mm adjusters stopping the cables. The non-Peugeot way is to have the housings stop the cables (or the inline Magura-type adjuster) with a slotted recess (hole with a bottom) instead of threads. You can convert to Peugeot style by drilling and tapping to M6-1.0 thread. But there is almost no adjustment range (because most of the hole is already too big, 7mm).

Magura “Wrap Around” silver controls are used on 1970’s Batavus, Colombia, Flandria, Foxi, Flying Dutchman, Hercules, JC Penney, Kreidler, KTM, Kynast, Murray, Odyssey, Puch, Sachs, Sears, Sparta, 74-85 Tomos, and others. These US models all had threaded holes for brake light switches. Most Euro and Canada models did not have brake light switch holes.

The brake cable holes on both sides have two versions, M6 threaded bottomless (Peugeot style), or 7mm plain hole with bottom (non-Peugeot style).

These controls on US models all had ball-end levers except for Sears Free Spirit.

Magura “Late Wrap Around” silver controls are used on 1980’s Colombia, Hercules, Murray, Puch, Sachs, 79-83 Trac, and others. The housings are thicker and less rounded. The left has a mirror hole. US models had threaded holes for brake light switches. But most Euro and Canada models did not have brake light switch holes. In these photos you cannot tell if there are brake switch holes or not.

The brake cable holes on both sides have two versions, M6 threaded bottomless (Peugeot style), or 7mm plain hole with bottom (non-Peugeot style).

The brake cable holes are 7mm plain with bottoms.

Puch-Magura “Sliding Block” black, used on 78-86 Puch deluxe models.

Most of these are the early, common kind with a screw on the slider holding holding the cable wire. The cable wire itself has no upper end piece. It takes a “universal” or “single ended” throttle cable.

Some of these are the late, uncommon kind with no screw on the slider. Instead the cable wire has an upper end piece 3mm “inline barrel” soldered onto it. The cable is specific to that set-up, and is “double ended”.

The brake cable holes are 7mm plain with bottoms.

Service Information

The tongue and groove lock together, but only when they are off the handlebar.

Magura Wrap-Around Throttle

As mentioned above, the pieces snap together, but only when removed from the handlebar.

Twist tube: The throttle housing has a tongue that goes into a groove in the twist tube. The two pieces are first locked together while off the handlebar, and then slid on as a unit. Then the twist tube is kept from moving sideways.

Thumb trigger: Not all mopeds have this, but all the wrap-around housings have a provision for it. This is also called a choke lever or a decomp lever. The trigger has half-circle-shaped posts that slide into slots in the throttle housing, but only when off the handlebar, and in the “squeezed past max” position. Once on, the handlebar prevents it from detaching.

Tomos A3 auto choke thumb button: This button, when pushed in, lets the throttle cable go all the way slack for cold starting. When it is not pushed in, it allows the cable to stay a little taut for normal idling. Idle speed is adjusted by the tightness of the throttle cable, at the handlebar by the Magura type cable adjuster.

Installing a throttle cable on a Magura wrap around type throttle

Installing a throttle cable on a Magura wrap around throttle

Installing a throttle cable: With an original Magura twist tube, the cable installs from the outer side, just behind the grip. Turn the grip forward to the closed position. Locate where the cable end is. Peel the flange of the grip there back with your thumb, and hold it there. With the other hand, place the sideways barrel end of the throttle cable into the cavity. Lay the wire over the ridge, and wrap it around the curved guide. When pulled taut it should fall into it’s groove. The throttle should pull the wire and move free.

With a Magura-clone twist tube, the cable installs from the inner side. So the twist tube has to be removed. That means the whole throttle has to be removed from the handlebar. But the cable is more protected.

How to install the throttle cable:

Worn throttle cable groove: The curved cable guide groove can become worn in the middle. It can become so bad that the throttle feels like a hack saw and makes a ripping sound like a zipper. When that happens the cable will soon be cut through and break. The cause of the worn groove is lack of lubrication. Moped cables and controls need oil occasionally.

Worn Magura wrap-around throttle housing

Restoring a worn groove

The remedy is to re-cut the bottom of the curved guide. The best tool is a masonry hack saw blade. It has the exact width and round shape. The linear saw is moved in a curved motion. The bottom of the channel is visually checked every few strokes, to see what areas need more cutting.

Installing a Magura brake lever spring.

Lubrication: Lube the cables and controls with a drip oil, like 3-in-1 or Tri Flow or any high tech lubricant. Tri Flow is thin so it penetrates in and clings to metal, like WD40. But after awhile when most of the liquid drys up, it leaves behind microscopic Teflon particles embedded in the metal surface.

Making custom cables: Here are the distances of the exposed cable wires, for Magura wrap-around type moped controls.

Handlebars

1. Handlebar Specifications

3. Original Handlebars

1. Handlebar Specifications

Dimensions are width, height, rise, clamp length, control length, pullback.

Natural angle: Close your eyes, clench your hands in a fist, relax, and put both arms forward and down a little. That is the natural position of your hands. They form an angle, called θf, viewed from the front, and another angle, called θt, viewed from the top. Handlebars are all close to the average natural position of human hands.

Positioning: Clamp-on handlebars can rotate in the clamps. During installation the rider chooses the best clamping position, for comfort and control. Most handlebars (except Clubman) are positioned with the rising part going straight up when viewed from the side. A rider with short arms might prefer a more rearward position, while a rider with long arms might want a more forward position.

Flipping (inverting): Any clamp-on handlebar can be flipped over (inverted). But most will feel wrong and strain the wrists. Of the handlebars shown below, only the Clubman and Drag bars can be flipped over, and still feel right.

Dimensions: Six lengths can completely describe a handlebar, without the need for angles. Here the side-view angle θs, and the top-view angle θt, are calculated from the lengths R, H, P, L, W, and C.

tan(θt) = 2*P / (W-C)

sin(θf) = (R-H) / L

Measuring: When measuring the dimensions, the end points are at the centers of the tubes, not the edges. The handlebar is placed on a flat table. With the rises vertical, the rise and height are measured from the center of the bar, straight down to the table, with 1/2 of the bar width subtracted (-0.4 inch). With the rises horizontal, the pullback is measured similarly.

Height: Looking from the front, most handlebars, especially low ones, slant down slightly going outward, at an angle θf, because the height is less than the rise. On some handlebars, the height is greater than the rise, and θf is negative.

Pullback: Looking at most motorcycle bars from the top, the bars slant rearward, at an angle θt, because the pullback is greater than zero. When the pullback is zero, θt becomes zero. Cruiser bars are for comfort and have a large pullback, where the bar ends point more towards the back of the bike. Drag bars are for high powered acceleration, and have a small pullback for control and grip.

2D or 3D: When the pullback is zero, the handlebar is 2-dimensional and will lay completely flat. Otherwise, most 4-bend (non-Drag) bars are 3D and do not lay flat on a table. 2D handlebars are simpler to make, but don’t feel “right”, except maybe at one particular position. 3D handlebars are more complicated to make, but will feel “right” in a range of positions.

Width: Wider handlebars allow better control. Off road bikes have wider bars. Narrow bars have less control, but are more aerodynamic for better fuel economy or higher top speed, and can squeeze through smaller spaces, like in between stopped cars.

Rise: High rise handlebars are taller, and put the hands higher. This can position the rider’s torso in a more upright position, for helping with back pain. Higher bars allow better control when standing up, like when jumping or hitting pot holes. Low rise handlebars put the rider leaning more forward. That reduces wind drag for higher top speed or better fuel efficiency.

Control length: Motorcycle handlebars need about 3 inches more control length than bicycle handlebars. They have thumb-operated levers or buttons, in addition to the finger-operated hand levers. Motorcycles have a twist throttle and a hydraulic brake on the right that takes up space. For motorcycles the minimum control length is roughly 8 inches. For mopeds it is about 6 inches. For bicycles it is about 5 inches. Any handlebar that has extra control length, can be cut shorter, up to the minimum control length, to reduce it’s width.

Clamp length: The center straight area needs to be at least as long as the clamps. Motorcycles have wider handlebar clamps than mopeds. Here is a table of moped handlebar clamp spacings:

xxxxxxxxx xx inner outer
Tomos A55 xx 1.7″ xx 3.1″ only this fork has enough inner space for bicycle bars with a 1″ x 1.7″ center bulge
Puch Maxi xx 1.55 xx 3.2
Hercules xxxx 1.2 xxx 2.4
Peugeot 103 x 1.2 xxx 2.3
Cimatti xxxx none xxx 2.4
Motobecane x 1.5 xxx 2.7

Applications: Not all mopeds can accept clamp-on “universal” handlebars. Some mopeds have bolt-on handlebars, where there are plates welded to the bar that bolt to the fork. Some mopeds have stem-mounted handlebars, where there is a long neck that goes inside the fork, held by a wedge bolt.

Thickness: Most modern 7/8 handlebars are 0.875 inch = 22.2 mm.

Vintage metric handlebars, are 0.863 to 0.866 inch = 21.9 to 22.0 mm.

The dual standard can sometimes cause problems.

22.0 controls on 22.2 bars: Wedge type controls, such as Domino, for 22.0 bars cannot fit on 22.2 bars. Wedge type controls do not clamp, but instead press a cone into the bottom of the handlebar. 1960’s, 70’s and 80’s “vintage” Domino controls have a fixed size hole, 22.0 mm, for 21.9 bars.

22.2 controls on 22.0 bars: Original vintage handlebars 22.0, with 1970’s Magura clamp type controls, require a strip of aluminum can under the clamp, to hold solid onto the handlebar. Otherwise the throttle slips around the bar. 1990’s and 2000’s “modern” Domino wedge type controls have a 22.3 mm hole, that works fine on either modern 22.2 or vintage 22.0 bars.

3. Original Handlebars

Most Original Equipment Manufacturer (OEM) handlebars are available in a range of conditions. All are straight, unless noted. Some are new, some good used, and some are pitted, peeling or scratched. Some have tiny scuffs from being jostled around in parts bins. They are priced accordingly. Photos of actual choices are available, by email.

Dual standards: Vintage European original bicycle and moped handlebars are 21.9 to 22.0 mm, to fit 22.0 controls. This metric standard lasted until the 1980’s. After the 80’s most European handlebars became 22.3 mm = 7/8 inch.

These bars are on certain 1978-79 models. The bottom of the handlebar has a chrome steel plate that says Garelli. The chrome handlebar plate bolts to the painted fork top plate. The fork top plate is made of stamped sheet steel. For these bolt-on bars the fork top plate was made too thin, causing most to crack near the edges of the handlebar plate. Garelli soon realized this problem, and stopped making the bars-with-plate design in 1979.

Tomos original sprockets made before 2008 said TOMOS and fit properly. The center splined hole fits tight and has no wiggle room. Most aftermarket sprockets, and ones made from 2008 on, do not fit properly. The center splined hole is bigger than it needs to be.

When the center hole is too big, the sprocket does not stay centered. Instead, it shifts back and forth every revolution. That make the chain pulsate, where it gets tighter and looser every revolution of the front sprocket. It feels like always being on a bumpy road. It leads to chain wear and sometimes damage to the driveshaft splines.

B. Rear sprockets

Sprockets in the same family have the same centering hole,
and the same bolt hole circle.

Families 1 to 12 sprockets are on the opposite side as the brake.
They are for mopeds and mini-cycles with a single drive chain.

1. Tomos lip x 60

Sprockets in this family are kept centered by the
lip that surrounds the small 17 mm center hole.

How to tell the chain pitch by measuring the sprocket

1. The teeth are counted. That gives n.

2. A round tapered tool like a punch or chopstick is placed in the sprocket tooth valley, and slid back and forth until it matches the half circle at the bottom of the valley. The tapered tool is measured where it matched the sprocket tooth valley. That gives dr.

3. If the tooth count n is an even number, the sprocket minumum diameter is measured directly with a caliper. If the tooth count n is an odd number, the sprocket minimum diameter is estimated. That gives dm.

4. Chain pitch is then calculated. pitch = (dr+dm)*sin(180/n)

How to calculate the holes diameter

When the hole count n is an odd number, the holes diameter d cannot be measured directly. d must be calculated from the measured hole spacing s.

d = s/sin(180/n)

How to tell if the teeth are worn

The valleys in between the teeth are U shaped. On a new sprocket both sides of the U are the same. As the sprocket wears, the side of the U that the chain pulls on becomes worn were the roller contacts it.

1. Chain Sizes

Pitch is the distance from one link to another. Pitch matters the most. The pitch, in eighths of an inch, is the first digit of the motorcycle chain size.

Roller Width (Wr) is the distance between the insides of the chain inner plates.

Named width is the minimum width of chain, and the maximum width of sprocket. The named width, in eighths of an inch, is the second and third digit in the motorcycle chain size.

Roller Diameter (Dr) is the third thing that matters for fitting a given sprocket.

Any replacement chain must have the same pitch and roller diameter (Dr). The roller width (Wr) should be the same but can be a little more. The roller width is correct for the sprocket width when the chain can move side-to-side on the sprocket, but only a little bit. So the sprocket width needs to be a little less than the roller width.

Chain replacement: When there is nothing else close to the chain except the sprocket teeth, the three blue dimensions, pitch, width, and roller diameter are all that matter for replacing an entire chain (and the number of links). These are related to the places that touch the sprocket. If the 3 blue items on the replacement chain are the same, it will fit the same sprockets.

The exceptions are when there are other things close to the chain. On some Chinese bicycle engines with a 415 chain, the engine case is very close to the chain. A 415H replacement chain is wider, scrapes the side of the engine causing damage and breakage. On vintage Motobecane mopeds there are rubber bands on the front sprocket that interfere with a 415H, preventing it from sitting all the way into the valleys. When those are in place a 415H does not mesh well. It sounds and feels terrible. Once the rubber bands are removed a 415H replaces a 415 perfectly. See Chain Service below.

Link replacement: For replacing a master link or one or more individual links, more things matter: inner width, pin length and pin diameter. On modern chains these 3 red items are standardized. But for vintage 1970’s and 80’s chains they were not. Often several different chains interchange (fit the same sprocket), but have different pin diameters, pin lengths, and plate thicknesses. So while the entire chain interchanges, the individual links do not. For example, a vintage Puch master link would not fit a vintage Garelli chain (because the pin is too thick). But an entire Puch chain would replace an entire Garelli chain.

Measuring: Chains for mopeds, motorized bicycles, gas or electric scooters, mini-ATVs, go-karts, mini-cars, and mini-bikes are not on most application charts. For these oddball vehicles you have to determine the chain size by measurement with a digital calipers, and counting how many link pins.

Metric and Inch Some Chinese made scooters and pocket bikes have 04B chains (6 mm pitch) instead of 25 (6.35 = 1/4″). Some have T8F or 05B chains (8 mm pitch) instead of 35 (9.53 = 3/8″). Metric chains look the same but don’t interchange with inch chains.

H versions: The H (heavy duty) versions fit the same sprocket but have thicker wider plates and thicker longer pins. So a 415 master link won’t fit a 415H chain (because the pins are too short), and a 415H master link won’t fit a 415 chain (because the pins are too thick).

At left is Myrons Mopeds master link cabinet, full of master links and half links from 20 other moped shops that closed in the late 1980’s in Southern California. Each of the drawers contains about 10 to 100 links. Each link was measured carefully and/or put through this gauntlet of Go/NoGo gauges, which are the actual master links and corresponding inner links contained in each drawer. From left to right, the order is smallest pitch first, smallest pin first (for that pitch), and the smallest inner width first (for that pitch and pin). Inner width for a master link is the space between the inside of the outer plates, which is slightly greater than the inner width for the chain, as in the chart below.

Notice that there are no “international” master links, like 04B (6mm) or 05B (8mm). These chains did not appear in California until the late 1990’s with the stand-up scooters, pocket bikes, and electric bikes and scooters, mostly from China.

4. Chain Service

How to install and remove master links.

Motobecane: 1970’s-1980’s Motobecane Mobylette 40, 50, or 50V mopeds, the front sprocket behind the large pulley has some rubber rings that interfere with modern 415H chains. Fortunately the two 1 1/4 inch rubber rings, one on each side of the sprocket, can be removed with something like a curved dental pick. This issue of a chain not meshing because of (unnecessary) rubber noise dampener rings contacting the outer plates instead of the sprocket contacting the rollers, also occurs on Peugeot, but not as much.

Left, the original IRIS chain, meshes correct.
Right, modern 415H, with taller plates,
rides up too high and does not mesh.

Motobecane front sprockets without rubbers.
Left, the original IRIS still meshes good.
Right, the 415H meshes good now.
The end roller is cut away to see the fit.

Peugeot 103: Sometimes the newer “H” rated chains do not fit until after the bike is rode for a few minutes. The two rubber rings on either side of the original sprocket interfere with the larger outer plates on the 415H chain, causing the chain to run higher and not mesh well. After riding awhile the chain noise gets less, as the rubbers get squished and interfere less. Still, it is better to remove the pulley, and remove the rubber rings, shown at right, to have a smooth running chain.

Peugeot 102: This is the only US-model moped that uses a 42 chain, same sprocket as a 415 (1/2 x 3/16), but lighter duty (thinner pins, thinner and smaller plates). Sedis made both 415 chain for Peugeot 103, and 42 chain for the lighter weight Peugeot 102. Old Sedis chains are often cracked. Then they break/throw the chain. No fun. To use a modern 415H chain, the two rubber rings on either side of the sprocket must be removed, or it won’t mesh properly. See photos at right.

Motorized Bicycles: 415 – Only Kind: Certain modern motorized bicycle gas engine kits use a 415 chain that passes very close to the engine case on both sides. These do not have enough room for the wider-on-the-outside 415H. They require a 415.

Motorized Bicycles: 415 and 410 Mixed: Certain modern motorized bicycle gas engine kits have a wide engine sprocket for 3/16 and a thin rear sprocket for a 1/8 chain. A 415 or 415H chain works but would be expected to have less retention (it would come off easier).

Motorized Bicycles: Long Chain Runs: Motorized bicycles with long chain runs need chain guides and/or chain tensioners, or else the chain comes off when it slaps going over bumps, or when the frame or wheel flexes, or when the engine mounts shift/slip. The kits don’t usually come with any.

American Made Minibikes: There were many different manufacturers of minibikes back in the 60’s and 70’s but most of them used either a 35, 40, 0r 41 chain. Number 35 was used on most all 4-5-6 inch wheel minibikes while 41 was used on larger minicycles such as Rupp Roadster II and Speedway. Number 41 chain will not run on a number 40 sprocket. Number 40 chain will run on a number 41 sprocket but it will be wider than needed.

Fun Karts and Minibikes: Many chains have the chain size stamped directly on the chain links. #35, 40, 41 and 420 chain are used in the Fun Kart and Mini Bike industry. An 11 or 12 tooth clutch sprocket usually indicates the use of #35 chain. 10 tooth clutch sprockets usually indicate the use of #40, 41 or 420 chain.

Why all of this madness about chains? All through the 1970’s and 1980’s when you needed a master link for your moped, you had to get it from a dealer that sold that kind, or else you had to bring in your chain and hope they could find one that fit. If you had a Motobecane and you needed a master link, you could not get one from a Puch dealer, even if you showed them your chain. Their master links had thicker pins. For decades, owners have been frustrated when they bought a #415 master link for their chain, and it did not fit. That’s because there are 18 or so different 415-compatible chains. By the 1990’s no moped shop sold master links, instead they made you buy a whole chain. Thankfully, there is much better standardization in this century, in moped chains. But there are still a lot of older moped chains and substitutes that are all different. So it’s still not possible to tell (guess) what master link a customers moped needs over the phone. Some things never change…

5. Myrons Chain List

Scan up and down the chart looking for similarities. Notice how the pitch P, and roller width W, and roller diameter D, can be the same for many different chains. Too bad the pin diameter A can vary with the maker. Ouch. A pin too big won’t fit. A pin too small will fit, but will be loose. The only way to get the correct master link is by knowing the pitch P, roller width W, roller diameter D, inner width W+2*T, and pin diameter A.

6. Moped Chain History

Vintage Moped Chains: Vintage bikes often have obsolete chains, or they specify the size in an obsolete way. Vintage equipment used the inch size, pitch x width. Modern motorcycles all use chain model numbers, like 428, 520, 630. The above chart shows that connection. In mopeds, there are 18 different chains, all size 415, or 1/2 x 3/16. They have different pin diameters and inner widths. In modern mopeds there are about 3 or 4.

Moped Chain History: When a shop installs a new chain, they throw the leftover pieces in a box. As the years go by, layers of chains accumulate, with the oldest ones at the bottom, as long as no one mixes up the pile. That’s one way to “date” chains. At Myrons, certain boxes of parts have been untouched since about 1985 to 1995. Only one little scrap of modern 415H chain was in that material, from those years. Not even 415H master links were in that time zone. This little scrap is what Shaun believes to be the earliest example of a 415H chain. Shown below on the Motobecane sprockets, it’s gold and says “Taiwan”. Taiwan bicycle products and machinery blossomed in the 1980’s. China made components came out about 15 years later.

Italian Chain History: At least five different Regina chains are original on 1970’s and 80’s Italian made mopeds, two that say “Regina Extra” and three that say “Regina” underlined. See their pictures above. They all have different master links! Craziness!

4.14 x 8.9 1.9 Regina (underline) 6a. tom1 (4.14 x 9.4-9.6)

Tomos Chain History: At least seven different Tomos chains have been used over the years.

Italy 1970’s 3.89 x 8.4

Germany late 1970’s 4.05 x 7.9

Germany 1980’s 4.14 x 9.4

ČZ chain Slovenia? late 1990’s 4.14 x 9.6

CIC 415H Taiwan? mid 2000’s 3.93 x 8.5

415H China? late 2000’s 3.93 x 8.5

Germany 2013-on 4.14 x 9.6

Above, seven Tomos chains take three different master links. The pins range from 3.89 to 4.14mm thick. The inner width ranges from 7.9 to 9.6mm. “Inner width” means measured between the inside walls of the outer plates. A wider inner link will not fit inside a narrow outer link.

First the “Regina underlined” (3.89 x 8.4) on early A3, and Wippermann (4.05 x 7.9) also on early A3, then Wippermann (4.14 x 9.4) on late A3, then ČZ (4.14 x 9.6) on A35, then CIC 415H on late A35, and now plain 415H (3.93 x 8.5) on A55 models. The chains got thicker and wider and taller on the outside, as the decades progressed. The pins got thicker, and then thinner, and now thick again: 3.89 ->4.05 -> 4.14 -> 4.14 -> 3.93 ->3.93 ->4.14. Same thing with inner width: 8.4 -> 7.9 -> 9.4 -> 9.6 -> 8.5 ->8.5 ->9.6. Perhaps this is why Tomos stopped selling master links…

Four kinds of moped pedal threads

Pedal threads: Most bicycle pedals have either 1/2-20 or 9/16-20 threads. But some vintage bicycles use “French thread” pedals, which is metric 14 – 1.25. The 14.0 mm thread is slightly smaller than 9/16″ (14.3 mm), but bigger than 1/2″ (12.7mm).

14mm pedals screw into 9/16 cranks all the way but fit loosely. Then later they break off or strip out easier.

9/16 pedals screw into 14mm cranks so tight they stop half way. Then later they break off or strip out easier.

2 P E D A L C R A N K S

Left and Right: With shoes it’s easy to tell if they’re on the wrong feet. But with moped cranks it is not. A left crank and pedal looks and functions the same as a right. So it is possible for a moped to have both left pedals and cranks, or both right, or the right on the left side and the left on the right side. Then when, say the left side pedal is missing, it might actually need a right, or visa versa.

Righty Tighty: This rule says “Viewed from above the bolt head, turning to the right, clockwise, is tightening”. Almost all bolts and nuts obey this rule because they are right hand thread. But left hand threads are opposite. They obey the opposite rule, “Lefty Tighty”.

How to tell: It is sometimes not easy to tell if a pedal or a crank is left or right. Most modern bicycle pedals are stamped L or R. Most modern reproduction cranks are also stamped L or R. Most vintage European right cranks are stamped D (droit, destra, desno, derecho) or R (recht, right). Some vintage European left cranks are not marked, and some are stamped S (sinestra) or G (gauche) or L (levo, left).

Another way to tell is by viewing the threads directly. When a right thread bolt is held with the tail facing up, each thread slopes upward going from left to right. When a left thread bolt is viewed the same way, the threads slope in the opposite direction. With crank threads, right thread goes inward clockwise, left thread goes outward clockwise. You have to follow the first thread around in a circle with your eyes.

How not to strip threads: Know which way to turn, and use lubricant. Know how it should feel. Know how tight it should be. And know how to use taps or dies or thread files to “clean up” damaged threads, before they fail completely.

434L, 434R Morini MO1 MO2

Shown here are the 3-style vintage Italian original pedal cranks on Italian (mostly) mopeds with Morini MO1, MO2, M1 engines. These cranks need to be the 3 style, that “goes outward right away”, because the engine sticks out close to the pedal shaft.

Besides clearing the engine when the crank is horizontal, sometimes this style crank is needed to clear the covers above the engine, when the crank is vertical.

Garelli Gulp

502 set on Garelli Gulp

Garelli Gulp requires pedal arms that go outward early, with a high offset. Here is the #502 pedal arm set that fits but the arms are one inch shorter.

These 502 pedal arms have 9.5 mm pin holes, but the holes are 1 mm closer to the pedal shaft, so they need 9.0 pins ground 1 mm thinner on the flat side.

518R, 518L ’70-95 Jawa

Shown here are the M3-style vintage German original pedal cranks on Hercules mopeds with Sachs 505 engine, such as the US-model “Sachs Balboa”. On a Taiwan moped with a Sachs 505 engine, such as “General 5-Star ST”, the pedal cranks are Taiwan made compatibles, that look different but have about the same dimensions and same style.

These “go outward right away”, not to clear the engine, but to clear the covers above the engine, when the crank is vertical.

517R Tomos A3

Shown here are the 4-style modern Slovenian original pedal cranks on 1986 and later Tomos mopeds, from late A3 to A35 and A55 engine models. Here the 2009 Tomos A55 engine pedal shaft is much longer than it needs to be, by 3/4″ on the left, and 1 3/4″ on the right, as you can see.

Back in the day, moped engines (and people) were thinner. The early 1974-79 early A3 pedal cranks did not have or need much offset, as shown at right.

Shown here are the 4-style vintage French original pedal cranks on Motobecane Mobylette mopeds 1972-1980+. On variator models, like 50V, the engine swings back as the bike speeds up. The clutch wheel often scrapes against the left pedal crank. On non-variator (Dimoby) models, like 50 or 40, the engine does not swing back as the bike speeds up (but it does swing to keep the belt tight). On those models there is also 3/8 inch more space between the clutch wheel and the pedal crank. So they “never” scrape.

Here are vintage Italian 6-style right and 3-style left crank arms for 1977-83 Garelli Gulp, VIP, and maybe Monza. The left has more offset than the right. It needs the 3 style that “goes outward right away” because the left side of the engine sticks out near the pedal shaft.

Shown at left are L3-style vintage Spanish crank arms for 1975-1986 Derbi Variant.

Shown at right are higher offset 3-style Spanish arms for 1986-89 Derbi Variant Sport.

Like Tomos and Garelli the later engines were wider.

614 Puch replica cranks

Shown here are the 0-style vintage Austrian cranks on 1978-86 Puch Maxi and Magnum models. There are also 1-style Puch cranks, on 1968-78 Puch Maxi. Those are the same dimensions except the bend is more sharp.

Puch threads
are intentionally
made weaker

What were they thinking? Pedal cranks for Puch mopeds have about 1/3 of the threads removed by machining. This makes them get stripped easier. The only plausible explanation is Puch was thinking about safety. When a rider forgets where the pedals are, and leans over in a turn, one pedal can hit the ground. If it hits hard enough it can cause a crash. Puch pedals are designed to break away, rather than causing a crash.

Pedal Crank Selection:

Offset: Ideally the pedal arms should have enough offset to not hit anything, even after being bent inward a little, yet not have too much offset. Too much offset causes the pedals to hit the ground sooner when leaned over, and to stick out more when parking or storing, and to hit the riders feet more when backing up.

Length: Longer pedal arms provide more leverage. For mopeds the pedals are mainly used for starting the engine, rather than pedaling. So if the engine turns over easily then long pedal arms are not needed. Longer arms hit the ground sooner when leaned over. And when not pedaling, one foot is more forward and the other is more back. So shorter arms are better, in many ways. But for pedaling, longer arms are better, especially for riders with long legs.

Style: Some engines or bikes need cranks that “go outward right away” because something is sticking out near the pedal shaft. This is the style 3 above. Sachs 505, Morini MO1, MO2 and Garelli VIP engines are some common examples.

Here it is held high up.

This has straightened

Straightening: 1. With a special tool like the one shown, and two people, a bent pedal crank can be straightened in one minute without any removal. The second person has to pull on the bike the opposite way, by standing hard on the opposite pedal. 2. Without that tool, the pedal only is removed and a long pipe that fits closely over the crank is used to apply torque. 3. For more stubborn cranks, the crank is removed and placed in a large bench vise. Again the pipe is placed over the crank at the right place, and torque is applied. Moped cranks require 100 to maybe 600 foot-pounds of torque to bend. This is done without heating.

Re-threading a crank

Re-threading: Often just the first few threads become messed up. Bicycle shops have pedal taps, size 9/16-20 Right and Left, that can repair partially-stripped threads on moped cranks. Hardware stores do not have those taps, instead they have 9/16-18, more coarse. So pedal taps are a bicycle-industry-only item.

Repairing pedal crank threads is done by starting the tap from the good side, which is the back. Sometimes crank removal is required, and sometimes it is optional. Cutting fluid, or at least oil, is applied. The tap is moved back and forth as it is screwed in (like 4 steps forward and 3 steps back), until it goes all the way through.

Rethreading a M14-1.25 crank to 9/16-20 (from 14.0 to 14.3mm) is more difficult. The plated steel is hard and tough. It takes longer and requires more force. The crank arm and tap get hot by the end of the 10-20 minute process.

Pin removal

Pedal Crank pins

These round pins have a flat wedge that fits tight against a slot in the shaft. They are pressed or hammered in and out. In the bicycle industry they are known as cotter pins. Here they are called crank pins or wedge pins.

pedal pin 9.5 mm $2,
pedal pin 9.0 mm $2 each.
special 9.0 x 6.5 $7 each. The flat is 1mm lower.

Right: regular 9mm pin
Left: same but thinner

One Up One Down: This rule says that if one crank pin points up, then the other should point down. This makes the left and right crank arms parallel at 12 o’clock and 6 o’clock. When the pins are both up, the arms are at 12 o’clock and 5 o’clock, lopsided and awkward.

Special pins: The 502 aftermarket pedal arms require special wedge pins. The regular pin shown on the right is 9.0 x 7.2 thick. After grinding it becomes the special pin on the left, which is 9.0 x 6.5 thick, or 1.3 mm thinner. These pins are required for the 502R and 502L aftermarket pedal arms. Price $8 each

4 P E D A L S H A F T S

Some mopeds with external pedal shafts, and separate pedal and motor chains, have one of the crank arms permanently attached to the shaft and sprocket. With those, to get a new sprocket-side arm you have to replace the shaft-with-arm.

Some mopeds with external pedal shafts, and separate pedal and motor chains, have no crank arms permanently attached to the shaft and sprocket. With those the sprocket-side arm can be replaced.

5 F R E E W H E E L S

Some mopeds have one drive chain and some have two. Two-chain mopeds, with both a motor chain and a pedal chain, have freewheels, like most bicycles. The freewheel is the rear pedal sprocket that spins free and goes “click click click” in the reverse direction, but locks up solid in the forward direction. The freewheel allows the pedals to be stationary even when the rear wheel is moving forward. The moped brands with right-side freewheels are Puch, Peugeot, Motobecane, Batavus, Sparta (Foxi), Hercules (Sachs), Piaggio (Vespa), Honda (PA50), Kreidler, KTM (Foxi), Kynast, Flandria. There are two brands with left-side backward freewheels, Jawa and Benelli. All of the other moped brands do not have external freewheels, but instead have a freewheel mechanism inside the engine unit.

The freewheel screws on and tightens with pedaling. Once it is tight, a special tool is required to remove it. The tool fits into slots in the freewheel center. Some low-end modern single-speed bicycle freewheels do not have removal slots. Those cheap kinds can be removed by destroying the freewheel. To remove a freewheel destructively without a removal tool, the freewheel is first disassembled, where all the little balls and clickers fall out, and then the inner hub is unscrewed in a bench vise or with a pipe wrench.

Most freewheels go on the right side of the bike and thus have right-hand thread, but Jawa and Benelli ones go on the left side of the bike and have left-hand thread.

Freewheel threads: Like with pedal threads there is a common size and an uncommon size slightly smaller.

The common size is 1.375″ – 24, which equals 34.92 – 1.06 mm. Most modern bicycles worldwide have this ISO (International Standards Organization) standard freewheel thread type.

The uncommon size is M34.7 – 1.00, which equals 34.70 – 1.00 mm. This “French” thread type is on vintage bicycles from France, Belgium, Spain or Switzerland, and on Motobecane mopeds with Motobecane-made hubs.

So the French freewheels are slightly smaller than the rest of the world, 34.7 instead of 34.9. That small amount does not matter as long as the bike is pedaled gently. But it does matter when the pedals are pushed very hard. Then the loose fitting threads on the wheel hub can strip out, a disaster.

It is difficult to tell which thread type a hub has, by measuring the thread tops with a calipers. The 34.92 thread hubs measure 34.65 to 34.7. The 34.70 hubs measure 34.55 to 34.6. On some hubs the tops of the threads are worn down and measure less. So a standard thread might seem like a French thread type. Because of this, it is better to put away the calipers and use “feel”.

When the freewheel and hub have the same thread type, the freewheel screws on easy, yet has no looseness. Looseness is felt with fingertips pulling and pushing the freewheel center side to side. When a 34.92 freewheel is on a 34.7 hub, the center of the freewheel can move 0.22 mm. Here is a video of that. That looseness or “wiggle” is felt. The same is true for any threaded thing. When a bolt fits a nut, it screws on easy and yet does not wiggle.

All of the freewheels in Myrons Mopeds inventory were measured by feel. For each bike model listed above, a sample rear wheel with original freewheel was measured directly by feel. The freewheel was removed. It’s threads were checked by screwing onto both a French and a standard hub. The wheel threads were checked by screwing on both a French and a standard freewheel.

Gauntlet of test wheels: MB 40, Batavus M48, Peugeot 103, Model 7 hub, MB 50, MB 50, MB 50VLA.
Not shown, Puch wheels and hubs, Sparta, Peugeot 102 hub, Kreidler, Sachs, KTM, Kynast, others.

Result: None of the hubs or freewheels had French thread, except Motobecanes with Motobecane-made hubs. Wow!

Result: All Leleu-made hubs have standard freewheel thread 1.375″-24, even those for Motobecane. All Motobecane-made hubs have French thread M34.7-1.0. All Motobecane-made “6-star” mag wheels have standard thread, but it is tapered and begins with French thread, so that either type of freewheel can be used.

How to tell: The best way to tell if a 1970’s Motobecane moped rear hub is Motobecane-made (and therefore French thread) is visually. There is an prominent M logo on the freewheel side. There is no step on the freewheel side, instead it slopes gradually. The flanges go farther out from the spoke holes. So from 100 feet away, viewed from the side, the Motobecane-made hubs appear larger than Leleu-made hubs.

Summary

All two-chain rear hubs or wheels, on mopeds from the 1970’s and 80’s, have standard freewheel threads, except Motobecane-made hubs on 1950’s -60’s and some 1970’s Motobecane mopeds.

A standard thread freewheel fits a French thread hub and works fine when pedaled normally. Only when a strong athletic person pedals very hard, the hub threads can strip off, requiring wheel or hub replacement.

Motobecane 100mm hubs
are also French thread

1950’s – 60’s Motobecane: Many models, maybe all, had French freewheel threads M34.7-1.0. In the 1960’s the parts manuals specified the thread. One example, shown at right, is for Motobecane AV88 and Motoconfort AU88. It lists the 18-tooth 15244 freewheel as having M34.7-100 thread.

The French freewheel thread cover up: It is very odd that, after 1976-77, Motobecane had two different freewheel threads, but they hid that fact. Instead they made the teeth different, 15244 (French thread) was 18 teeth, and the newer 14298 (standard thread) was 20 teeth. The Motobecane America parts manuals list both freewheels without explanation. There does not seem to be anything about freewheels in the Parts or Service Bulletins. The physical freewheels do not say the thread. The actual parts labels do not say the thread either. As a result, this cover-up has caused confusion and mystery for 39 years (1978-2017).

7. Calculated Lengths

1. Spoke Length

Length can vary by 1 or 2 mm depending on the definition.
Spokes from the bicycle industry use Inner Edge Length.
Spokes from the moped industry use Center Line Length.
Spokes measured directly usually use Total Length.

Here we use Center Line Length. So a spoke that we say is 144 mm long, is 143 mm long from a bicycle spoke supplier, or 145 mm long from simple measurement.

2. Quick Info

Replacement spokes can be up to 2 mm longer or shorter, as long as the original spoke was not already long or short.

Inner or Outer: Spokes can go inside the hub flange or outside. On original moped wheels they alternate inner and outer. Inner spokes are longer because they have less than 90° bend. Outer spokes are shorter because they have more than 90° bend. Here we use the 90 degree equivalent for the named length. See illustration.

Spoke thickness goes by several wire gauge families. Scroll down to Spoke Threads and Gauges for details.

Spoke threads: Most spokes have rolled threads, where the thread tops are raised higher than the spoke. Some spokes have cut threads, where the thread tops are lower than the spoke.

Thread pitch: Here the meaning of “thread” is the width of one thread, in mm. So ten 0.60 threads is 6 mm length.

ID Marks: For each spoke thickness (gauge) there can be several thread pitches. For many that means the ID mark on the spoke must match the ID mark on the nipple. ID marks include (A) (R) Italy, ( ) UK/Asia, (∴) USA, (Б) Swiss, (♣) (U) Germany, (C) (B) (*) (+) or (Я) France. Scroll down to Spoke Threads and Gauges for details.

Definition of size

Size: The size of a drum brake shoe is not it’s actual length and width. The size is the width, and the diameter of the imaginary circle which the arc is a part of, which is also the brake drum diameter. Notice that the actual length is a little less than the drum diameter. So a 90 x 20 mm brake shoe is actually about 84 mm long by 20 mm wide.

Brakes that have the same drum diameter and width, can still be different, because of these things: the pivot post can have different positions, thicknesses and widths, the spreader shaft can have different positions, thicknesses and widths, the spring holes can have different positions and widths. So the size is actually several numbers, not just two.

Note 1. EBC322 requires grinding. Without grinding the spring rubs and makes noise. The depth is made just deep enough so that the coils of the spring never touch the brake shoes. In the photo, right is before grinding, left is after.

Note 2. All pre-1978 and some 1978-80 Motobecanes have Motobecane brakes, MB# 21730 (EBC876). There is a left and a right shoe. Most Motobecanes have these brake shoes, but some 1978-80 have Leleu brakes, MB# 16104 (EBC322). On those both shoes are the same, like most other drum brakes.

Note 3. EBC322m is made from a EBC322 by 1. slight grinding of the sides at the spreader end, 2. dremmeling on the inner side of the spreader spring hooks to make the spring stay farther away from the spreader cam, 3. reusing the original MB springs because they are thinner.

Note 4. The Grimeca 90×18 brake shoe has the most moped applications. It is on almost all Italian moped and mini-bike spoke wheels. It is also on German (Hercules), Austrian (KTM), Yugoslavian (Tomos), Mexican (Carabela), and American (AMF) moped spoke wheels. The Italian made Grimeca 90×18 brake shoe is second only to the French made Leleu 80×18 brake shoe in total number of units.

Note 5. Grimeca-U brake shoes are the same as Grimeca except for the spring. The red places in the photo are what is different. Grinding and drilling are necessary to convert Grimeca type shoes to Grimeca-U type.

Note 6. There is no visible difference on the outside, between a V-spring brake plate and non-V-spring (U-spring or dual coil) brake plate, but inside there are three differences. 1) the cam shaft on a V-spring type has a retaining plate, while a coil spring type has no plate (to allow installation by “folding the taco into a tortilla”). 2) the pivot shaft on a V-spring type is longer and has a rounded groove for the V-spring. 3) the pivot shaft on a V-spring has no center groove for retention, while the coil spring and U-spring types have a center groove (for the center ridge on the shoes). In this photo the left 2 are U-spring and the rest are V-spring.

Note 7. These are the older Jawa spoke wheel brake shoes, with 5.0 mm thick lining instead of 2.5mm. That makes the diameter increase from 85 to 90mm, to fit “Italian standard 90mm” moped wheels.

Note 8. These are EBC613 brakes with the pivot post half-hole widened from 8mm to 9mm, for the bigger Indian post, and with thinner Indian coil springs.

Note 9. The modern aftermarket EBC613 spring holes do not have enough material and strength for a U-spring. The older Indian brake shoes have much more material around the spring holes. So EBC613 cannot safely be drilled out to accept a U-spring. That’s why Indian90U replacements are unavailable.

Note 10. Many Indian mopeds with beautiful Taiwan-made Mira snowflake mags need these brake shoes, because the originals deteriorate and/or de-laminate. These EBC brakes look different, with different ribs than original, but they are an exact replacement.

Note 11. EBC601 is the same as EBC615, except the lining is wider. Grind off 2.5 mm from each side to make a 615 from a 601.

Note 12. Derbi brake plates can have two different cam thicknesses. Older models 1977-78 mostly had 10mm thick cams and 105251 brake shoes. Later models from about 1979-on had 8mm thick cams and 105252 brake shoes. See photo. 105252 shoes have steel plates on the cam end, but 105251 do not. To make 105252 shoes fit on an early 10mm cam either the steel plates must be removed from the brake shoes, or the 10mm cam ground thinner to 8mm.

Note 13. Derbi 105252 brake shoes (for 8mm cam) are made in two versions that interchange. Derbi-105-open type shoes have half-circle pivot ends, while Derbi-105-hole shoes have full circle pivot ends.

Brake Shoes Info

Types: There are four types of drum brake shoes used on mopeds:

1. Open type with coil springs: When the center of the wheel is small enough, the open type with coil springs is preferred because servicing is easier. To install, connect the springs and place the shoes in the shape of a taco. Then fold the taco into a flat tortilla. That stretches the springs without any tools. Then tap the shoes with the handle of a screwdriver until they snap into place. The advantage of this style is easy servicing.

2. Hole type with coil springs: These brake shoes have a large hole in the pivot post end, and two small coil spring holes. They cannot be installed by “folding the taco into a tortilla”. But they also cannot separate from the pivot post. The advantage is slightly more safety.

When the center of the wheel is big and the brake drum is small, the U spring or V spring type is required. Otherwise the coil springs rub on the wheel center and make a violin sound.

3. Open type with U spring: The U spring goes inside the pivot post. The brake shoes and brake plate are the same as the hole type with coil springs. Only the spring is different, a single large U-spring instead of two small coils. For Grimeca 90 x 18, minor modifications to the coil spring brake shoes are required to fit a U-spring. See below. The advantage of this type is greater spring clearance and compatibility with type 1.

4. Hole type with V spring: The V spring goes outside the pivot post. These brake shoes have a large hole on the pivot end (not the smaller spring holes), and the V spring goes around the pivot post. So the pivot post has a rounded groove for the spring. The advantage of this type is slightly more reliability and safety.

But installing the spring is difficult and requires a special spreader tool. At left is that tool. It is made from a M6 x 30 screw, nut, washers, special lip-washer for centering, and a 12mm piston pin. The piston pin end and screw head are ground to fit the spring so it can’t slip off. Price $15

Installing Leleu 70mm replacement brake shoes

The replacements have thinner and weaker spring anchor hooks. They can break off during installation when the spring has to be stretched to go over the hook. To prevent breaking the spring hooks, there are two things on the brake plate that need to be ground. One is the top lip on the pivot post. It needs to be reduced in diameter, but with some lip remaining for retention. The top edge needs to be rounded. That helps to not overstretch the spring. Two is the top lip on the spreader cam. It too needs to be reduced, but with some lip remaining for retention.

Once those areas are ground, the shoes can be installed with just fingers and no tools. Do not use prying tools. Only fingers are needed.
