Reflectors

July 14, 2014

updated 2022-01

Identification and Dating: Original reflectors have to comply with safety standards in effect at the time they were made. The compliance markings that are molded into the front plastic give a clue to when and where the vehicle was made. The vehicle is always made after the compliance standard, usually many years later. Original tail lights and head lights also have compliance standards that can be used in identification and dating.

Ink stamps: Some reflectors also have an ink stamp on the back indicating the date that the reflector was made. The date the reflector was made is usually many years after the compliance date.

SAE Society of Automotive Engineers is a USA based standards organization that now is worldwide and called SAE International.

UNECE United Nations Economic Commision for Europe makes worldwide standards for automotive equipment and other things. The UNECE “E” number, with a circle around it, on the reflector indicates compliance for a particular country. E1 is Germany, E2 is France, E3 is Italy, … E11 is England, E12 is Austria and 59 other countries worldwide. See country codes for UN reg. 3

JIS Japan Industry Standards are separate from Europe. East Asian countries like Taiwan, China and Korea use Japan standards. So reflectors made in those countries do not have an “E” number.

Speed nuts:  Nuts normally screw on, but speed nuts push on. So they should more properly be called “push-on fasteners”. Once “on” they cannot be removed, except by using a dental pick tool to pry and bend back each of the inner petals.

Self-threading nuts (thread cutting nuts) screw on to plastic posts. They can be removed easily, but should not be tightened as much as a normal nut that size.

Broken posts: It is difficult to remove speed nuts without breaking the plastic post. Because of that, many used reflectors have their posts broken off. When that happens the reflector can be re-used by drilling a hole where the post was and using a small screw and nut, instead of the post and speed nut.

Cushions: All of the major moped brands that have reflectors attached by speed nuts use cushions under the speed nut, except Vespa (Piaggio). The cushions protect the posts from breaking and reduce the damaging or annoying effects of vibration.

Shocks

July 14, 2014

Welcome. Shocks are priced and sold by each unless stated.

Price Range: Dark green price is for used in rough condition. Bright green price is for new condition. Some shocks are available in various used states, ranging from “rough” to “like new”. So the dark green is the lower limit, and the bright green is the upper limit, of the price range. Most will be in between the low and the high, and priced accordingly.

N/A means Not Available. 

 

Damping: Most of these rear shocks do not have hydraulic fluid (oil) damping. Since most are pure springs with no damping, they are very bouncy. Certain high quality ones have some damping, and are less bouncy.

Length: The length is from center of hole to center of hole.

Width: Besides length and eyelet sizes, some shocks are limited in width by the frame or body panels. On Motobecane for example, you can’t put wider shocks even with the same length and eyelets (unless some bodywork is cut off).

Stiffness: You can’t tell how strong a spring is, until you squeeze it. Heavier people need heavier springs, and vice versa. 

Travel: Mopeds are for going slow on smooth roads, and so do not need much suspension travel (how far the wheels can move up or down when hitting a big bump). More travel makes the bike taller, but more able to handle bumps. 2 to 4 inches is typical.

<< This Tomos 221032 shock has more travel, more precision, and other features that make it outperform most other moped shocks. It has some damping, more than other moped shocks, but not as much as a true hydraulic shock. It is also adjustable in spring preload (stiffness) for different rider weights. The longer travel makes bumps feel smaller.

1. Ball Bearings

 Ball bearing types

Loose    the balls can be removed individually (and roll away forever)

1-piece  the balls are in a retainer ring than cannot be removed
1-piece  the contact is radial in a full-U shape “full contact”
1-piece  for carrying pure-radial loads (perpendicular to the axle)

3-piece  the balls are in a retainer ring that can be removed
3-piece  the contact is angular in a half-U shape, for some side loads
3-piece  only Bo15, L17 and E20 are 3-piece “angular contact”

1-piece versions

00    open: has no shields or seals
RS   sealed: has a rubber seal on one side
2RS double sealed: has rubber seals on both sides
Z     shielded: has a shield on one side
ZZ   double shielded: has shields on both sides

The shields or seals are pressed in. They can be removed by poking a small hole with something like a dental pick, and then prying the hole outward.

Note 1: This is on 1984-later Puch E50 engines, with crankshaft 349.310.1150 (not 349.110.1150). It has the same dimensions 17 x 40 x 12, but the inner race on the side opposite the outer clip groove is recessed by 1 mm to 11. It is also for the Top Racing crank, and other late-80’s compatibles.

Roller bearings can carry more weight, but are for low rpm. Thin long rollers are called “needle”.
Ball bearings can take higher rpms and have less friction than rollers.
Rollers can be horizontal (radial loads), angled (radial and side loads), or vertical (side loads).
All of these below have horizontal rollers for pure radial loads.

The benefits of a needle bearing compared to a bushing are 1) ability to operate with low lubrication, 2) less friction and therefore less heat generated, 3) floating needles can fit a small range of diameters, as long as OD minus ID equals twice the roller diameter.

One side has writing and an anti-clockwise arrow. The other side is plain.
Viewed from the writing end, the shaft can only rotate anti-clockwise. Clockwise it locks solid.
Installed in a Tomos clutch drum, the writing side faces out.
When a Tomos piston seizes, this can get damaged, and become locked in both directions. 

6. Bushings

Spacers and bushings are metal or plastic tubes, that can have the same appearance. The name depends on what the tube does. A “spacer” carries an axial load, where the length matters the most. A “bushing” carries a radial load, where the diameter matters the most. Bushings are also called “plain bearings”. Spacers are also called “distance bushings”. This source of confusion is similar to that of “mopeds” and “scooters”.

Clacking vs Clattering

Precision Reaming

Most of these require reaming after they are pressed into the rod. The reasons are 1) they have a very tight press fit for their size, so much that the inside diameter becomes smaller after they are pressed in, and 2) some are made slightly larger or smaller than others. Only Puch and Jawa offered pre-reamed piston pin bushings, which can sometimes need light reaming. The reason why not every kind is made pre-reamed, is that pre-reamed or re-used ones do not hold as tight as un-reamed new ones. When they don’t hold tight they can slip easier.

Disaster strikes: Piston bushing slippage causes oil hole blockage. Then the piston pin and bushing do not get any lubrication. Not having oil mixed with the gasoline also causes the piston bushing to not get any lubrication. Without oil, soon the bushing overheats and sticks-melts to the piston pin. That causes the piston pin to rotate back and forth inside the piston, instead of being stationary. After a while the piston pin holes wear out. The loose piston begins to make a clacking sound at idle and a screeching sound at high speed. The compression ratio is reduced by the loose piston. That causes the engine to be less powerful and difficult to start. The incomplete combustion also makes the spark plug black, which worsens the tendency to be difficult or impossible to start.

1. Seals

Seals are for sealing rotating or sliding shafts where they emerge from a sealed compartment. Fork seals and shifter shaft seals are sliding type. Engine seals are rotating type.

This seal inner lip has a circular thin coil spring that holds onto the rotating shaft. Click to enlarge and see the tiny coils of the spring.

Most engine seals are for preventing oil leakage. When four-stroke crank seals leak, the engine still runs the same, but oil drips out. But two-stroke crank seals are also pressure seals, keeping air in (or out). When they leak, gas-oil mist leaks out, and fresh air leaks in. Then the engine won’t idle or accelerate good. That is because two-strokes “breathe” through the crankcase.

Metric seals are specified by their type and size (inner, outer, and thickness, in mm).

Applications and year ranges listed below are for models that sold new in the USA. Many of the year ranges would begin earlier or end later for worldwide models.

1. Quarter-turn 27mm

This is a special size gas cap, only found only on some Trac models:

1983-90 Clipper, 1982-86 Eagle, 1984-88 Escot, 1984-89 Liberty, 1986-89 Olympic, and maybe 1988-90 Blitz.

It is part number 21204 or 17620-M56-8900. 

A 30mm quarter turn cap is too big and cannot be made to fit by simple grinding.

2. Quarter-turn 30mm

For quarter-turn gas caps, the named size is the inner diameter of the filler neck it fits into. The actual size of the gas cap is a little less than the named size. That’s why a 28mm gas cap on the internet is called 30mm here, or a 38 is called 40 here.

4. Quarter-turn 40mm

For quarter-turn gas caps, the named size is the inner diameter of the filler neck it fits into. The actual size of the gas cap is a little less than the named size. That’s why these are called 40mm here, but they are called 38mm elsewhere.

8. Push-in 28mm

The early Vespa Ciao, 1967-68 up to frame #154099, had a light gray plastic 28mm push-in gas cap. Myrons does not have any, not even a photo.

After that it was a 32mm push-in.

 

9. Push-in 30mm

The named size of push-in gas caps is the inner diameter of the filler neck, 30mm. The actual size is smaller, 28 or 29 so it can slide in. But the seal lip or rubber ring is bigger 31mm, so it can get squeezed as it pushes in.

10. Push-in 32mm

The push-in gas caps 10a, 10c, 10d, 10f have a thick rubber ring that is made too large, 34-35mm. Right out of the package it is too big to enter a 32mm gas tank filler neck, even with grease and care. The rubber ring must be ground down to reduce the outer diameter to 33mm. This makes the price a few dollars more.

It’s amazing how much that Derbi gas cap shrank, from 32 to 30mm. And how the one from the newer model shrank, but the older model one did not. So a badly shrunken one could fit nicely on a Peugeot! Other soft plastic push-in gas caps with lips, not rubber rings, also shrink, like Peugeot. Only those 35 year old NOS ones that have been kept in a sealed plastic bag are not shrunk.

 Early Garelli Super Sport mopeds had this 42mm screw-on gas cap, while later models had 30mm quarter-turn gas caps. The M42x1.5 external threads on the tank measure 41.5mm. The M42x1,5 internal threads on the cap measure 40.5mm. Many of these shrink with age, unless they are kept in a sealed plastic bag. Then the internal diameter decreases from 40.5 to 40.0 or less, and the cap screws on tightly or only partially.

These gas lids are not shrunk because they were kept in a plastic bag for 40 years. Others that are shrunk are offered at half price. Those were exposed to the air for 40 years.

Almost all moped gas caps are vented. Some have a vent switch. When you transport the bike laying on it’s side, gasoline drips out of the air vent hole in the gas cap. With a vent switch you can close the vent hole during transport or storage, and open it during regular use.

Gas caps come in 4 types. 1. Quarter turn, 2. Push in, 3. Screw on, 4. Pop up. Each type has different sizes.

Quarter turn gas lids on mopeds. L to R, 30, 40, 60mm

30 and 40mm quarter turn “regular wing”, 40mm quarter turn “external wing”. Many other quarter turn wing styles are possible. Two other moped styles are nick named “thin wing” and “wide wing”.

Quarter turn has two “wings” on opposite sides that enter two slots in the gas tank lip. Then when the gas cap is rotated 90 degrees to the right, which is one fourth of a turn, it locks on and seals the outer edge by the spring tension in the wings. The spring has a certain amount of “travel” that allows the lid to work (seal) on a range of gas tank lip thicknesses, or as the rubber or cork gasket gets thin. But sometimes a thicker rubber washer is needed to get the wings to push harder and seal better. In the 30mm size an extra 2mm thick rubber is sold here, but not for 40mm, at this time.

Push in lid gas tanks have a smooth round wall, about as deep as it is wide. The lids are usually black plastic with thin flexible circular ridges that press against the wall. The entrance has a taper for easy operation. In the 1977 USA moped standards, push in gas lids were supposedly required to be quarter turn. Puch, Cimatti, Garelli, and Sachs switched from push-in to quarter-turn but not everyone else did. Again in 2010, quarter turn gas caps are mandated in the USA, this time not for safety reasons, but for environmental ones.

Screw on lid gas tanks have threads. The lid must be screwed on one or more full turns clockwise. The threads on the lid can be either female (internal) or male (external). Most modern screw on lids are more like bottle cap threads, more coarse than machine threads. Also the tops and bottoms of the threads have wide plateaus. Some are at right, not listed.

Pop up gas lids are generally on top tank mopeds and modern motorcycles. Turn the key or push the button and the lid pops open.

Vent Hole: All moped gas caps are “vented”. That means they have a tiny pinhole or channel that lets air get in or out. If the pinhole is blocked, after awhile a suction will develop, the gasoline supply will stop, especially with a full tank. They all have a vent design that prevents gasoline from shooting out, like a wall or a maze, but lets air get through. Some gas caps have a vent switch, “on” or open for riding, “off” or closed for transport and storage. All vented gas lids will leak gas if the tank is too full or leaned over too far.

Shrinkage: Unless they have been kept stored in an air tight bag, many of the vintage moped plastic gas caps shrink after 20 or 40 years. The Peugeot and Colombia black plastic push-in 30mm lids become 29 or 28mm. The 32mm late Derbi black plastic push-in lid becomes 30mm. The Garelli 42mm screw-on black plastic lid becomes 41 or 40. When a push in lid shrinks, it gets loose and falls off. One remedy for that is a “leash” made out of a twist tie. Another remedy is a thin rubber o-ring, but it’s hard to find the correct size. With push-in gas caps, the actual diameter will be slightly more, about 0.5 millimeter, than the tank hole inner diameter, to make a light press fit. So a 30mm lid should be 30.5mm wide, a 40 should be 40.5. With screw on male lids there can be shrinkage and the lid will still function, because it does not seal on the loose threads. But when a female (internal thread) screw-on lid gets smaller, it becomes tight and difficult or impossible to screw on.

Info General

Info General

General was the actual name of the importer/distributor, General Moped Company, which somehow superseeded, possibly bought out or took over, Grycner and Lazer in 1979. Generals were made from 1979 to 1985 by Jui Li Enterprise Co. Ltd, 22 Konan Rd, Jenwu Hsiang, Kaohsiung Hsien, Taiwan, R.O.C.

5-Star is a top tank, Minarelli V1 or Sachs 505, F&R hand brakes.
5-Star ST is a step thru, Minarelli V1 or Sachs 505, foot brake.
5-Star TE is a step thru, Minarelli V1L, Italian made monotube.
5-Star LTD  is top tank, Minarelli V1L oil injected with mags.
5-Star C2  is a top tank, Minarelli V2 variator engine.

Grycner Floozie

1978 Grycner Floozie

Grycner is the name of the US importer/distributor, Grycner Motors, Palm Springs, California USA . Grycners were made from 1978 to 1979 by Jui Li Enterprise Co. Ltd, 22 Konan Rd, Jenwu Hsiang, Kaohsiung Hsien, Taiwan, R.O.C. Jui Li only produced mopeds. Grycner Floozie is a step thru with a Sachs 505 engine, foot brake, identical to a General 5-Star ST. Grycner was replaced by General in 1979.

Grycner was the only moped that came with “dingle balls” decorations on the handlebars.

Info Lazer Sport 50

Lazer is a trade name made by the US importer/distributor, North American Roosevelt Industries Inc, 405 Park Ave, New York, New York 10022. Lazers were made from 1977 to 1979 by Jui Li Enterprise Co. Ltd, 22 Konan Rd, Jenwu Hsiang, Kaohsiung Hsien, Taiwan, R.O.C.. Jui Li made only mopeds. Lazer Sport 50 (originally Sprint 50) is a 1977 top tank, bright orange, with a Minarelli V1 engine. It looks identical to the General 5-Star, but there are subtle differences. There is also a less common 1979 Lazer with a Morini MO-1 engine.

 

 

1977 Lazer Sport 50

The Lazer Sport 50 got it’s good looks from France.

The Lazer Sport 50 is a copy of this earlier 1975 Peugeot Sport

Lazer and General are Taiwan copies of this,
an earlier French, 1975 Peugeot Sport moped.

 

 

 

 

 

 

 

 

 

1978 Lazer Sport 50

1978 Lazer Sport 50, in paradise.

The Lazer Sport 50 and the later General 5 Star are both copies of an earlier 1975 Peugeot Sport 50. That is why (Taiwan) General side panels interchange with (French) Peugeot 103 ones.

In 1979 Lazer was replaced by the  “General 5 Star”. Some components (controls) and frame details changed also, so a 1979 Lazer Sport 50 is about 95% the same as a 1980 General 5 Star. 

Thirty years later, the Lazer name is again on mopeds. This time it’s a Chinese four stroke, made by Chongoing Astronautic Bashan Motorcycle Manufacturing Company LTD (Bashan). That modern 2007-later 4-stroke Lazer, also known as SSR, is not covered here.

A.M.S. was made by Her Chee Industrial Co., Ltd, 2 Yikung 1st Rd, Yichu Industrial Area, Yichu Hsiang, Chiayi Hsien, Taiwan, ROC. Her Chee began in 1978 making “moped bikes” with their own brand name “AMS” (Adly Moped and Scooter). In 1985 they switched to making scooters, kid’s motorcycles and ATVs with their new brand name “Adly Moto”.

AMS mopeds were made from 1979 to 1984. They here with the Jui Li-made mopeds because they are 90% the same. They are not Jui Li remakes, because they were made concurrently. The US importer was A.M.S. Imports, 923 Moana West, Reno Nevada 89509, or 1110 S Wells Av, Reno NV 89502.

Wirings and Other Electrical

September 13, 2012

Generic Wiring Harness

 

This is a main wiring harness for 3-or-more-coil moped magnetos (ignition, lights, brake light). It can be configured for 2-coil magnetos (ignition/brake light, lights). See below for possible configurations. It is shown as a photo and a schematic. It comes with the round chrome switches, right for engine stop, left for headlight and horn. Price $95

This is only the front main harness. A rear harness, engine to tail light, and connector block are needed to make a complete harness, but they’re not included.

Here is that generic wiring harness adapeted to fit a Garelli (US model), with an external ignition ground on the blue magneto wire.

5. 054704 voltage regulator    6VAC $25.0 40w used MB with heat sink

Regulators 1, 2 and 3 can interchange. They all regulate the voltage on the yellow wire, by dumping any excess voltage into the brown wire, that goes to the frame. They keep the AC voltage below about 13 volts. This allows the use of a stronger generator, for brighter lights when stopped and the engine is idling. The stronger generator would otherwise be too strong when the engine was running fast, and would make a voltage over 13 volts, maybe 14 or 16. That would make the lights super bright, but they would soon burn out. The regulator prevents bulb burnout from too much voltage. The bulbs can also burn out from too much vibration. The regulator would not help that.

Regulators 2 and 3 have blade connectors that are duplicates (connected together inside) or unused (not connected inside).

2. Tubes Info

 

 

Here are two actual sizes, labeled as four.
Upper 2 say 3.25/3.50-18 and 2.75/3.00-18.
Lower 2 say 2.50/2.75-18 and 2.25/2.50-18.
This is label dishonesty.

 

 

Expansion: One tube size can fit a range of tire sizes, because the rubber can stretch. The tube gets bigger as it is inflated with air, until it presses against the inside of the tire.

Correct Size Criteria: When a tube is the correct size for a tire, and it is inflated slightly (but not expanded), it should fit inside the tire. It should not need to expand out to contact the tire. When a tube is too thin, it has to expand, which makes it more vulnerable to punctures. When a tube is too wide, it has to be wrinkled or folded to fit inside a thin tire. Where the folds are at can lead to punctures caused by internal rubbing.

Label Dishonesty: There are some tubes with misleading labels. Like with food, you think you’re getting more than what is actually there. Comparing the weight is the best way to know how much rubber you’re getting. The bicycle industry does the same thing. The label says a bigger size than the tube really is. That uses less rubber, saving the manufacturer money. But the tube has to stretch more when inflated, so the wall thickness is less, which causes it to get punctured easier. Because of this mislabeling, some are recommended for a different width tire than what the box label says. Always compare weights when shopping for tubes, not just “size” and price!

4. Tire and Rim Info

 

Motorcycle tires are for 8, 9, 10, 12, 13, 14, 15, 16, 17, 18, 19, 21 and 23 inch rims. See below.

Bicycle tires are for 12(16×2), 13.2(18), 16(20×2), 18 (22×2), 20(24×2), 22(26×2) inch rims.

History: Before the 1970’s motorcycle and bicycle tires were the same. Some time in the late 1960’s, as safety standards improved, motorcycle and bicycle tires were separated. Bicycle tires were given even rim sizes, while motorcycle tires were given mostly odd rim sizes. Motorcycle tires for USA motor vehicles had to comply with DOT safety standards, with speed and weight ratings. Bicycle tires had different safety standards. 

Correct size: The insides of the tire must match the outer sides of the rim, where the tire seats at. If the tire fits too loose it will work for low pressure only. At normal or high pressure the loose tire would tend to bulge out, allowing the tube to escape. Then the tube balloons out quickly and pops. If the tire fits too tight, a section of the tire will not stretch over the outer side of the rim. This happens when the center rim band is too wide or when tape is placed over the rim outer sides. In either case the tire will not seat correctly. One or both sides will have a flat section, instead of a perfect circle. That causes a bumpy ride on perfectly smooth streets, less grip and control.

Correct installation: The inner tube must be completely inside the tire, not pinched between the tire and rim. It often gets pinched near the valve stem, if the stem is not pushed way inward before tire mounting. That makes the tire fit too tight, causing the above problems, plus the pinched section will become chaffed (worn), leading to a flat tire later on. 

 

14 inch rim (356 mm)  

Fourteen inch rims are pretty much only on mopeds and junior off road bikes.

15 inch rim (381 mm) 

Wide tires for 15 inch rims are common on modern street motorcycles, like “130/90 -15” (5 inch wide) to “170/80 – 15” (6 1/2 inch wide), but thin 15’s are uncommon. Size “2.50 – 15” (2 1/2 inch wide) is pretty much only found on 1970’s small trail bikes by Yamaha, Kawasaki, and others.  No bicycles have that 381mm rim size. So there’s only this one choice.

This 1973 Yamaha GT1 80cc has 15" rims, with "2.50 - 15" trail tires.

16 inch rim (406 mm) 

Tires for sixteen inch rims are on about 1/3 of all USA mopeds, while 17″ is the other 2/3. Almost all Italian mopeds use 16″ rims, with mostly 2.25 – 16 (20.5″ OD) tires. Juvenile and BMX bicycles all use 16 inch rims, but they are called 20″ in the bicycle industry. Yes, 20 x 2.125 bicycle tires interchange with 2.25 – 16 motorcycle tires, because they both use 406mm rims. Motorcycle tires for on-road use have to meet US DOT standards, and have many things labeled on the tire. Bicycle tires have different safety standards, and are not legal and not safe to use on on-road motorcycles.

18 inch rim (456 mm)             

Some 1960’s tires were labeled narrower than modern tires. The Harley Davidson M65 original tires said 22 x 1 3/4 (1.75 – 18), but they were actually 2.00 or 2.25 in width. You can see the restored M65 rear tire is thinner than the rim. Yet in old photos the tires are wider than the rims. A 2.25-18 motorcycle tire is a better choice than a 22 x 1.75 bicycle tire.

19 inch rim (484 mm)

Many vintage motorized bicycles had 19 inch rims, with (now obsolete) bicycle tires size 23 x 2.0 (equal to 2.0 – 19 or French 550 x 50B). By the 1970’s, tires were smaller and wider, 16 and 17 inch. Of the US model mopeds, only the Solex had 19″ rims. 19 inch tires thinner than 2.75 are not sold by normal USA motorcycle or bicycle tire suppliers. The thinnest “metric street” tire available is 80/90 – 19, which is about 2.75 – 19.

20 inch rim (507 mm) 

Some vintage motorized bicycles had 20 inch rims, that accept bicycle size 24 x 2.125 “balloon” tires. For them, fat bicycle tires, for a mini beach cruiser, are an affordable option. Street classic tread all black is shown, but other choices exist. Whitewall 24 x 2.125 available also. Most bicycle shops carry 24×2.125 tires also. The ISO number on every bicycle tire is what tells the rim size. This tire says 57-507, which means 57mm wide (2.24″) and 507mm (20.0″) inner diameter.

20.5 inch rim (520 mm) 

1958 Parilla moped tire for a 20.5 inch rim

Here are all tire sizes near 20.5” rim:

(ISO 483 = 19.0″) 2.25 – 19  motorcycle
(ISO 507 = 20.0″) 24 x 2.0  bicycle
(ISO 520 = 20.5“) 24 x 1¾ S7 for old Schwinn
(ISO 533 = 21.0”) 2.50 – 21  motorcycle

 

 

21 inch rim (534 mm) 

Twenty one is a common front rim size on off road and street cruiser motorcycles. The thinnest street tire is 80/90-21, which equals 2.75-21. The thinnest off road commonly available is also 2.75 – 21. Vintage French bicycles had 21″ rims with “600B” or “24 x 1-1/2” tires, but not modern bicycles.

Any rim can be measured to determine the bead diameter, where the tire sits. One way is to wrap a cloth measuring tape around the tire-less rim to measure the circumference, then divide by 3.14. See Sheldon Brown Rim Measuring for more details.

22 inch rim (559 mm) 

Some vintage motorized bicycles had 22 inch rims, that accept bicycle size 26 x 2.125 “balloon” tires. For them, wide bicycle tires, for a beach cruiser or mountain bike, are an affordable option. Street classic tread all black is shown, but other choices exist. Whitewall 26 x 2.125 available also. Most bicycle shops carry 26×2.125 tires also. The ISO number on every bicycle tire is what tells the rim size. This tire says 57-559, which means 57mm wide (2.24″) and 559mm (22.0″) inner diameter. For more about tire sizes see Sheldon Brown Tyre Sizing. Bicycle tires are intended for low speed and low weight. They have no motor vehicle safety endorsements, like “street-legal” or “DOT” tires do. They are listed here to show what all the choices are. But they are not recomended for use on motor vehicles.

Notice 22 = 26 – 2*2.0

 

23 inch rim (584 mm) 

Twenty three inch rims are on antique motorcycles, and on some off road front, and also some on road front customs for novelty. Modern downhill mountain bike racers use 23 inch rims, called “27.5 x 2.0”. 1950’s French bicycles use 23″ rims, called “650B” or “26 x 1-1/2”. Some modern commuter bikes also use 650B tires (584mm rim), in-between a mountain bike 26″ (559mm) and road bike 700C (622mm).  Antique motorcycles from the 1910’s, 20’s, 30’s use the bicycle system, where the tire size means the outer diameter. So, at least some 28 x 2.5 tires correspond to 2.50 – 23, but maybe not all. A 28 x 2.5 or 28 x 3.0 antique replica tire costs around $200 and up from Coker Tire. Measure the rim diameter precisely to determine the rim size, on any vintage, antique, or unknown motorcycle. A 23-inch-rim tire costs ten times as much as a 22-inch-rim tire!

24 inch rim (610 mm) 

For some reason, there are no bicycles or motorcycles, except for some antique ones possibly, with 24″ rims. If there were any antique motorcycles with “28 x 2.0” or “29 x 2.5″ tires, they likely had 24” rims. Most early motorcycle tires were “28 x 2.5″, assumed to be a 23” rim, or “28 x 3.0″, assumed to be a 22” rim. 

 

25 inch rim (635 mm) 

Twenty five inch rims are not on any motorcycle. They are on older traditional bicycles, still common “work horse” bicycles in Europe and Asia, today. In less developed places in the world, the 28 x 1-1/2 tires, rod brake (not cables), always black, classics out number all other vehicles. The “700B” French size tire had a height of 32 or 33mm, to make an outer diameter of 700mm.

This 1940 Solex has 25" rims, with "700B" or "28 x 1-1/2" tires. Notice 28 = 25 - 2*1.5

As you go back in time, tires were bigger and thinner, just like with automobiles!

 

5. Dual Meaning of Tire Size

A bicycle 16 inch tire fits inside a motorcycle 16 inch tire.

A 16 x 2.50 fits inside a 2.50 – 16.

Rim size is at bead seat.

The “size” of the tire has a different meaning for bicycles, than for motorcycles and cars. For bicycles, the tire size means the outer diameter of the tire. For motorcycles and cars, the tire size means rim size, which is the inner diameter of the tire. So a 20 x 2.125 bicycle tire fits a 16″ moped rim. Conversely, a 2.25 – 16 moped tire fits a 20″ bicycle rim.

Vintage motorcycle tires: After about 1969, motorcycle tires no longer used the bicycle system. From then on, “22 x 2.0” meant bicycle 18 inch rim, and “2.0 – 18” meant motorcycle 18 inch rim. Bicycles were given the even numbered rim sizes 16, 20, 22 while motorcycles were given the odd numbered rim sizes 17, 19, 21, 23, pretty much. Bicycles were given the “outer times width” syntax “22 x 2.0”, while motorcycles given the “width dash rim” syntax “2.0 – 18”. The “x” and the “-” are not interchangeable. Also the order is not interchangeable. This was a new way to tell the difference between a bicycle tire and a motorcycle tire, just by the “tire size”.

Rim measurement: You can measure any rim with a tape measure, and determine the tire size. Try to measure the rim diameter at the “porch”, where the tire sits, not the “lip” at the very edge. A 16″ rim will have a total diameter of 16.6″. So don’t count the lip.  This method settles the confusion of whether a marking or specification is using the bicycle (tire OD) or motorcycle (tire ID) system. Older mopeds often have 2.25-18 (22 x 2.25) and 2.25-19 (23 x 2.25) tires. They used the bicycle system. Modern moped-size (thin) tires, since the 1970’s, all use the motorcycle system, in the USA. Some modern electric scooters have an oddball size, 16 x 3.00. It’s a bicycle size, because a 16 x 2.25 bicycle tire fits, but wider. It’s a solid aluminum disk rear wheel, and so the inner tube valve stem must be the 90 degree type. The rim diameter at the “porch” is about 12″. A motorcycle inner tube size 3.00-12 fits perfect, but they are only available with straight valve stems. Tires and tubes for those must be purchased from the dealer or distributor of those electric scooters.
