Myrons Mopeds

 

USA Models 1974-1986

 

All models use 50:1 pre-mix, two-stroke oil and gas, except those that say “oil injection”.
Modern unleaded gasoline is OK to use. The “do not use unleaded” label is obsolete.
All US models have automatic transmissions. Most are one-speed, but some are two-speed.

The plain Maxi and Rigid models have the 7-side-fin “low-torque” engine top end.
The other step-thrus have a 8-side-fin “hi-torque” top end (head, cylinder, intake and carb).
The Magnum top tank models have the 9-side-fin “Magnum” engine top end.

Each model came in three horsepower versions, different for each US state.

wide spoke wheel means rim is 1.35 inner width,
thin spoke wheel means rim is 1.1 inner width.
ff means front fender. A thin front fender needs a thin 2.00-17 tire.

1980 carry overs: In 1980 there were 2 or 3 years worth of mopeds produced. They were stockpiled and sold in 1981, 82 and 83. This was not just Puch, it was many manufacturers. It was a way to avoid the new worldwide motor vehicle standards and labeling requirements. Motor vehicles made before 1981 were not required to have the modern 17-digit VIN with assigned manufacturer codes. And there were other safety and standardization requirements for motor vehicle manufacturers.

That is why there are 1980 models in the 1981 and 1982 line ups!

Not long after Hans Renold invented the roller chain in 1880, Johann Puch invented the safety bicycle in 1880. A year later Puch and two business partners started Styria Fahrradwerke, making safety bicycles that were chain driven, allowing the rider to sit closer to the ground. Traditional bicycles at the time were the direct drive big wheel type. Those were more dangerous and difficult to ride. The 1981 Magnum Limited commemorates the centenial anniversary of Styria, later known as Steyr Daimler Puch after merging with Austro-Daimler in 1928, and Steyr-Werke AG in 1934.

1. Parts for Laura M56 Engine

The parts list below is made from the Batavus USA Spare Parts Catalog for 1978-80 Regency VA and Regency HS (20, 25, 30 mph). Combined with that are parts from the Trac USA Parts List for 1982-86 Clipper, Eagle and Hawk (25 and 30 mph).

In 1978-80 the M56 engine was made by Laura in Holland, mostly for Batavus mopeds. It was remade in 1982-85 by Daelim in Korea, mostly for Trac mopeds. The Trac remake is 90% the same. Only some pulley, pedal and drive shaft parts are different, shown below in a lighter color shade.

Note 1: The original belt T5X395 with 79 teeth was unavailable for many years from about 1990 to 2020. During that time the only belt available was one tooth (5 mm) shorter T5X390, sold online by Get-to-It Sales. The shorter belt was too tight unless the rear pulley teeth were shaved down. Many M56 rear pulleys have had their teeth shaved. With shaved teeth the shorter belt fits but the original belt is too loose.

To get a correct fitting belt, here is how to tell if the tops of the teeth have been shaved off. Original uses T5X395. Shaved uses T5X390. This is important because there is no way to adjust the belt tension, and no automatic belt tensioner.

2. Parts for Laura M48 Engine

The parts list below is made from all three versions (20, 25, 30 mph) of the Batavus USA Spare Parts Catalogs shown at right, for models 1976-80 VA, HS50, Mo-bat, Bronco, Starflite VA I, Starflite VA II, Starflite HS.

1970’s USA Batavus dealers were given parts books only for their state’s speed version, and not other state’s. So a dealer in 25mph state like Arizona did not know, and could not easily find out, what parts were different in a 30mph state like California. There were just a few pages that were different.

3. M48 Engine Parts Information

Small clutch parts: Most of the small clutch parts are in this photo.

Top row, #17 840010 tab washer, #4 820502 hex bolt, #5 843500 washer, #6 480981 plate, #61 480892 leaf spring, #22 480887 saucer spring (used), #20 820520 splined bolt.

Bottom row, #24 813081 needle bearing, #23 816180 felt ring, #41 490814 washer, #22 480887 saucer spring, #79 480899 washer.

Saucer spring: You can see the shiny rings on the used saucer spring. They are where the contact was. The dark areas never touch anything. 

Leaf spring: The leaf spring goes on any one of the ten tabs of the friction plate, under the basket. What it does is reduce vibration. It stops the jingle bells sound, and helps the friction plate tabs last longer. It is not essential, but very beneficial. 

Crank Seals: Laura M48 uses crank seals that are 1 mm smaller (tighter) than normal.  The 15mm right side has a 14x30x7 seal. The 21mm needle bearing case on the left side has a 20x42x7 special seal with an offset lip. 

Friction Plate #480889: 10 tabs, each 10.5mm wide, inner diameter 58.5mm, outer diameter 92.4mm (100.4mm at tabs), thickness 3.65mm.

Note: The tabs break off when the slots in the basket become worn or notched on one side. This is because not all ten tabs are sharing the load evenly. A worn clutch housing/basket also makes the clutch stick and not go into “neutral”.  

Pulley-Housing #480880: 10 tabs, 10.3mm wide, ID 94.0mm, OD 98.6mm, center needle bearing ID 15.0mm, OD 21.0mm, length 22.0. Comes with the needle bearing only. Price $150 new, $100 almost new not worn. Far left, a new one and a worn out one. The slots for the tabs get worn wider where the plate tabs push at. Filing those flat will help, but it might still stick sometimes.

 

Pulley-Housings: 480880 (painted red) has a wide pulley for US 25, 30 mph and Euro 40, 45, 50 kmh versions. 480894 (painted yellow) has a thin pulley for US 20 mph and Euro 25, 30 kmh versions. 480880 red is deeper (25.5 mm) than 480894 (24.4mm).

 

 

 

 

 

 

 

 

 

 

Clutch Washers: The Batavus crank goes from 12mm to 15mm right at the edge of the needle bearing. The clutch needle bearing is lubed by the gasoline and oil mist in the crankcase. The three special steel washers, one cupped, seal the crankcase pressure on the spinning crankshaft, along with the rubber crank seals.

 

First the felt ring #23 goes into a recess in the housing-pulley #71. Then the large 15mm washer #41 goes on, just over the 12-15 step in the crankshaft. Then the 12mm saucer spring #22 goes on with the dish side up (outward). Then on 25 and 30 mph versions with the brick red pulley, the 12mm small washer #79 goes on, into the dish of the saucer spring. Then the aluminum clutch hub with large steel saucer in back goes onto the flat sided part of the crank, and rests against the #41. When the outer nut is tightened, the saucer spring is compressed slightly, so that the crankcase is sealed by the metal-to-metal contact ring between #79 and #22. When the engine is running, but the rear wheel is stopped, #79 spins, but #41 is stationary. Once the bike gets over 10mph, #41 and #79 are both spinning in sync, so the metal-to-metal pressure seal gets better.

 

Crankcase Pressure Leaks: All of this special washer business allows the needle bearing to never need greasing. But if a washer is missing, there is a small pressure leak. A small crankcase pressure leak causes a small loss of engine power at low speeds.

On a two-stroke crankcase the leak alternates in both directions. Piston going down causes some fuel mist to get pushed out. Piston going up causes some fresh air to get sucked in. Then the cycle repeats. Because of the rapid reversal of direction, at low engine speeds the leak has more time to happen, due to inertia. So the effect of leaving out one of the washers is to cause less “low-end torque”. The engine is weak until it gets going fast, then it is normal but lean.  

There is a small grease seal in the needle bearing #24. But it is not a pressure seal with a ring spring. So it is sealed partially, even without the washers. That is why leaving out the washers only causes a small loss of low speed power.

Left Crank Seal: The clutch side crank seal is special. The lip lies outside of the edge plane. That is to say, it sticks out. On most other seals the seal lip lies in between the edge’s planes.

A regular seal lip is in the wrong location. It cannot hug the needle bearing shell.

 

 

Engine Covers:

Laura M48 magneto (right) and clutch (left) covers are the same. There are different versions, including aftermarket, and different stickers.

Motobecane, Laura Batavus, Laura Badger, TYM Angel, TYM Speed Bird magneto covers all interchange, because they all have a 124 mm inner diameter. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This is an aftermarket 124mm ID engine cover for an ’80’s Motobecane. You can see it looks slightly different but fits Batavus. Price $18 with two rubber fastener tabs.

Conclusions:

To upgrade a 25 mph to 30, you have to change the carburetor assembly, head, sprocket and exhaust. 

To upgrade a 20 mph, you have to change the “whole” engine, carburetor, exhaust and sprockets.

The M48-03 (20 mph) version parts are made to not interchange, so you can’t upgrade easily. The clutch hub with smaller front pulley is painted golden yellow and uses a thinner and longer belt, so you can’t put a 30mph clutch hub, painted brick red (the belt would slip because the sides don’t touch). 

From a distance you can tell a 30mph version by the extra think 28mm exhaust header.

From a distance you can tell a 20mph version by the yellow clutch and thin long belt.

1973 to 1975 Batavus VA (step thru), VA Deluxe with Laura M48 engine:

These early Batavus mopeds had Domino controls. The purple VA on the left has a Domino left control and a Magura right control. Weird. The orange VA on the right has a Domino left control and a Domino wrap around throttle right control. It must have a thumb lever for the choke but it is not very visible.

Hercules Mopeds Speed Versions

For Hercules mopeds, made from 1975 to 1980, that sold new in the USA, here are the things that determine the speed version: cylinder-and-crankcase, exhaust header pipe, intake pipe, carburetor, air filter cover, and rear sprocket.

 

 

 

 

 

How to tell: The cylinder says “25km” or “45km”. The cylinder head fins are either slanted (A,B) or straight (D). The exhaust front pipe is thick or thin. The carburetor says “85/10…” or 85/12…”. The air filter inlet hole is big or small. The rear sprocket is big or small. Find the model row in the table that has the same sizes and ID numbers, to determine what speed version your Hercules moped is.

This information was not easily available. Sources are all factory manuals, parts, service, and owners.

The model numbers are confusing. Here is the explanation.

1970-1977 Hercules P1, M1, M2 (sheet frame)

These models all have stamped sheet-metal frames with Sachs 504/1 engines. The pedals are part of the frame. There are two chains, motor and pedal.

This says in 1975 the US model of Hercules sheet-frame had a 504/1BS engine, 1 hp 20mph. The Canada model had a 504/1A engine 1.8 hp 25-30mph. The two 1976 models shown below agree with that. The 1975-76 USA model was branded “Hercules” but the Canada model was called “Moppet”.

1973-77 Hercules M4, M5, P3, HR2 (tube frame)

These models all have tube frames with Sachs 505/1 engines. The pedals are part of the engine. There is one chain.

 In 1976 the US DOT adopted new standards for mopeds. US states chose their on speed limits. In 1977 Hercules mopeds were imported to the US in 20mph (25km motor) and 25/30mph (40km motor) versions. The 30mph states sold the 25mph versions.

In the July 1977 book “Complete Book of Mopeds” it says “Just beginning to be brought into the United States, the German made line of mopeds called Hercules uses the well respected Sachs engine. Four models are presently available in the United States.” It goes on to describe the four models, 3 tube-frame-single-chain and 1 sheet-frame-dual-chain. M4 with chrome gas tank. HR2, an M4 with chrome crash bars, high exhaust pipe. An M4 variant economy model, less chrome, and a P1 sheet frame. Those other models are not in any internet images, so they did not sell much, if at all. The majority of 1977 Hercules for sale in the US were M4, in several flavors.

US Models:
1975:  M4 505/1B (20mph), P1 504/1BS (20mph)
1976:  M4 505/1B (20mph), P1 504/1BS (20mph)
1977:  M4 505/1B (20mph), P1 504/1BS (20mph), M4 505/1A (25mph)

 

 

 

 

 

 

 

 

 

 

 

You can tell a US model moped by the side reflectors and the lights. A Euro model has no side reflectors and the lights are smaller. Here they are side by side.

In 1977 the importer was Sachs Motor Corporation of USA, headquartered at 909 Crocker Rd, Westlake OH 44145, and later at 6401 Regio St, Buena Park CA 90620. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This flyer discloses the true identities. The Westlake is a P1 model and the Balboa is a M4 model.

 

1978-79 Sachs Westlake, Balboa

In 1977 the US models were given American names.

The P-I (P1) with stamped sheet frame was called Westlake, after the town of Westlake Ohio where Sachs USA was headquartered. The engine covers changed from grey to black.

The M-I (M4) with tube frame and separate gas tank was called Balboa, after Balboa Island and Balboa Peninsula, in Newport Beach California. Here is a Sachs Balboa ad showing the historic Balboa Island Ferry that holds three cars and crosses the Newport Harbor channel every five or ten minutes. Myrons Mopeds had several group rides where 30 or 40 mopeds crammed onto that 3-auto ferry. Each bike paid 25¢ for the thrill of floatation. 

United Moped was located in Fountain Valley, near Newport Beach. They were also the US distributor for Foxi mopeds, both Sparta made in Holland, and KTM made in Austria.

In December 1978, United Moped sent out this Sachs dealer price list to it’s dealers, who were already selling Foxi mopeds, both Sparta and KTM types. The list shows the official model names. The Westlake (Hercules P1) was either P-I with spoke wheels or P-II with “snowflake” mag wheels. The Balboa (Hercules M4) was either M-I with spoke wheels or M-II with mags. 

 

 

After 1977 there were three USA speed versions:
30mph  504/1D, 505/1D
25mph  504/1A, 505/1A
20mph  504/1B, 505/1B

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1979-83 Sachs Suburban, 1980 Sachs Sundancer

In 1980 the Westlake was re-named Sundancer. The engine covers remained black. The tail light changed from ULO to CEV. The exhaust changed from black to all chrome. The CEV round chrome switches changed to CEV black plastic.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In 1979 the Balboa M-II with mags was re-named Suburban. The tail light changed from ULO to CEV. The engine covers changed from grey to black. The exhaust changed from black to all chrome. The CEV round chrome switches changed to CEV black plastic.

 

 

 

 

1980 Sachs Seville, Prima, Prima G3

 

 

 

 

 

 

 

 

 

 

After 1980 new requirements for moped manufacturers came into effect. Motor vehicle manufacturers worldwide were required to be registered, and to have a manufacturer code which is the first 3 digits of the new 17-digit Vehicle Identification Number. Many other requirements for noise, safety, and labeling came into effect. Decreasing sales and increasing regulations drove most European moped manufacturers out of the US after 1980. They stockpiled 2 or 3 years worth of 1980 models. Shaun’s dad’s shop Royal Cyclery sold 1980 Sachs Sundancers from 1981 to 1984. The same thing happened for the other makes. They all avoided making 1981, 82, 83 models. Moped shops throughout the USA sold 1980 models mostly, during 1981, 82 and 83.

 

1982 Bombardier-Hercules Eagle I, II, III

Somehow Bombardier, in Canada, had Hercules make the bikes anonymously, for just one year, maybe a single batch. The H logo is still on the gas cap and the headlight brackets. The Eagle owners manual is available online http://projectmopedmanual.info/Manual_HTML/sachs.html but it does not say the actual manufacturer or representative. It only says it was printed in Canada. The blank ID plate shown has both English and French language, so it is Canada compliant at least, and maybe also USA compliant. Many of these bikes were sold in the Great Lakes states Minnesota, Wisconsin, Illinois, Michigan. But none or almost none were in California. So Eagles are anonymous and regional. 

 

 

 

 

 

 

 

 

The 1980’s: While the last production year for US-model Hercules mopeds was 1980, sales of 1980 models continued into 1981 and beyond. The Motorcyclist Magazine 1981 Buyers Guide https://www.myronsmopeds.com/category/1981-buyers-guide/  lists several “1981” Sachs models: Sundancer $665, Suburban $740, Prima $793, Seville $892, Prima G3 $993 est.

Bike maker Nürnberger Hercules-Werke stopped supplying bikes to the US after 1982. But engine maker Fichtel & Sachs continued to make engines for Columbia (USA), KKM (USA), Sparta (Netherlands), Jui Li (Taiwan), Her Chee (Taiwan). The bike makers had Fichtel & Sachs engine parts and service manuals. The last US-model with an actual Sachs 505/1D engine is a KKM Mopet, 1988 to 1990, made in Ohio USA. So the Sachs engines lasted 8 years longer than the Hercules-Sachs bikes, in the USA.  

The rise in popularity of well-made low-cost 50 or 80cc Japanese scooters like Honda Spree, Elite and Yamaha Razz, Riva plus the increased regulations for drivers licenses, registration, plus the lower price of gasoline, contributed to the last Sachs-Hercules moped shipped from Germany to the USA, in 1982, and the last Sachs moped engine shipped from Germany to USA in 1990.

The 1990’s: Hercules continued making the same sheet-frame and tube-frame type mopeds, for sale in Europe, until 2006.

 

 

 

 

 

 

 

 

 

 

 

The 2000’s: New clean air regulations came out in 2006 for 50cc bikes, in many places worldwide. That caused many 50cc two-stroke engines to be discontinued. A few years before that, in 2002 Handy Bikes in Columbus Ohio, considered importing a model like the 2002 Hercules Prima 5S, but with a 1-speed automatic Sachs 505/1D engine, side reflectors, brake light, and turn signals. It would have been called “Sachs Suburban” just like 1980. But the cost was too much. It would have sold in 2003 for $1800, comparable to a 2003 Tomos for $1050 or $1200.
