Columbia  made in USA by Columbia  Sachs or Solo engine

Columbia is one of America’s best and oldest bicycle makers.

1913 Pope (Columbia) racer

From the days of true horse power, their bicycle was “an ever saddled horse which eats nothing”. Colombia and Montgomery Ward mopeds are made by Colombia Manufacturing Company, Division of MTD Products Inc, One Cycle Street, Westfield MA 01086

Columbia has been credited with many firsts in the biking industry, since its founding in 1877 by Col. Albert Pope. It has pioneered many improvements to the industry, producing bikes, motorbikes, and furniture for nearly 150 years. Here is the Columbia Manufacturing Inc website, history page. http://www.columbiamfginc.com/columbia_history.html

America’s first moped, is also Shaun’s favorite. Hats off to Columbia! This is a well made, long lasting, economical, safe, and fun bike, very strong and sturdy but not heavy. Definitely one of the Top Ten Mopeds of the 1970’s. Can you dig it?

KKM VIN Info: KKM mopeds were made after 1980, and thus were required to have the 17-digit Vehicle Identification Number and other requirements that the Columbia mopeds did not have.
Digit 1 is the Country, 4 = USA 
Digit 2,3 are the Maker, 33 = KKM Enterprises
Digit 4 is the Line, A = Frame A, B = Frame B (tube or sheet, don’t know which)
Digit 5 is the Type, A = two wheel, B = three wheel
Digit 6 is the Engine Maker, S = Sachs, M = Minarelli, L = Solo, R = Morini 
Digit 7 is Engine Model, 2 = Sachs 505 1D, 1 = Sachs 505 1A 
Digit 8 is Hub Type, C = cast 105mm, B = pressed 105mm, A = pressed 90mm

Digit 9 is check digit 
Digit 10 is Model Year, J = 1988, K = 1989, L = 1990

Based on this and the photo of the red 1988, it’s VIN is 433AAS2CxJxxxxxxx, where x is any.

WELCOME. Columbia parts for sale are found in their various type categories. These are Sachs Motors, Solo Motors, Bing Carburetors, Bosch Magnetos, CEV headlights, Merit switches, ULO tail lights, VDO speedometers, Grimeca wheel parts, brakes, spokes, tires and tubes, Magura controls, chains, sprockets, cables, bearings, seals, engine hardware, pistons, gas valves, gas caps, pedals, pedal cranks, axle parts, seats, exhausts, steering, handlebars, grips, bulbs, forks, fenders, racks, covers, mirrors, etc. Use this table to specify or identify the item for your Columbia model. Then look for it in the Parts by Type menu. Some of the parts category web pages are finished, some are being constructed, and some are still blank. Please email Shaun with a question of a part that you cannot find. 

After days of studying “all” of the Columbia, Mopet and Montgomery Ward parts manuals, service manuals, owners manuals, brochures, photos from the internet, and many actual known parts, this is the result, concentrated and useful information, for you to use. Enjoy!

Notes

Sachs 25 and 30mph exhaust headers

Speed Versions – The only difference between a 25mph Columbia with a Sachs 505/1A engine, and a 30mph one, is the exhaust front pipe or header. The 30mph version is 28mm OD, and the 25mph one is 22mm OD.

Speed Versions – The only difference between a 20mph Columbia with a Sachs 505/1A engine, and a 25mph one, is the rear sprocket. The 25mph sprocket is 42 teeth, and the 20mph is 48 teeth.

#420 Rear Sprocket (on sheet metal frame models) is thicker than most moped sprockets. While most are 4.3mm thick, for #415 or 415H chains, the Columbia (sheet metal frame model) one is 5.5mm thick, for a #420 or 420H chain.

The 42T x 45.5 x 5.5 original sprocket can be replaced with a 42T x 41.5 x 4.3 Italian moped one, but the center hole has to be precisely cut 4mm bigger, on a lathe. Then the chain can be a 415 or 415H, like the front sprocket is.

#415 Rear Sprocket (on tube frame models) has a 115mm center hole, bigger than any other moped sprocket. That is because of the oversize 105mm drum brake that goes inside the sprocket. Having the brake and sprocket on the same side allows the opposite side to have a screw-on freewheel sprocket for a pedal chain.

Brakes made in USA by Columbia are compatible with Grimeca brakes made in Italy. The cast aluminum Grimeca brake shoes directly replace the stamped steel brakes. The USA made brake plates, cam shafts, lever arms, are also each interchangable with Grimeca items.

Gas Valve (sheet frame) is located on the left front, close to the decompression valve and start cable. The original had the hose spigot on the right, heading toward the carburetor. Although right is prefered, the replacement gas valve can have the hose spigot going down or left. Shown above is a “12×1 spigot down” replacement petcock, on a yellow Columbia.

Electrical: Columbia lights are completely separate from the ignition. Never will the engine die when the brakes are applied or when the brake light wires are loose, like on many other mopeds. Each of the lights has it’s own generator wire, so they are independent of each other. The 6V 22W AC yellow wire powers the head light, speedo light and horn, the 6V 10W AC green (and green/black) powers the brake light, and the 6V 5W grey wire powers the tail light. Those three lighting source coils, plus a fourth ignition source coil (perhaps 20 volts but not officially rated), comprise the “Bosch 6V 22-5/10″ magneto-generator.

Solo Type 254/255 Engine
Coolant plug above spark plug

Solo Engines are made in Germany by SOLO Kleinmotoren GmbH, Postfach 600152, D 71050 Sindelfingen, Germany. Solo made mostly small agricultural motors, chain saws, sprayers, etc. The name is from the revolutionary backpack portable sprayer for pesticides in 1951. The “Solo” could be used by a single person for the first time, whereas in the past pesticide sprayers required a heavy stationary motor pump and several assistants to handle the long hose. See Odyssey, Solo for more.

Notes:

Clutch Seal: The pressure seal for the clutch side on the 254/255 is not just one seal, like normally. It is two seals, the outer one 26x35x7 seals case-to-clutch, and the inner one 15x21x3 seals clutch-to-shaft. This is the Laura clutch seal/bearing design, similar to Batavus. Instead of being separate in it’s own grease, the clutch needle bearing is bathed in the two stroke oil and gasoline. The benefit is it never needs to be greased. The drawback is the crankcase pressure has another place to possibly leak, both fresh air inwards, and fuel/air mist outwards.

How to identify a 1 or 2 speed: There are two types of belt-drive transmissions, 1 speed and 2 speed. The one-speed (ein-gang) “regular” transmission has a solid rear pulley, with no screws around the edge. The two-speed (zwei-gang) transmission has a rear pulley with planetary gears and a second speed auto clutch inside, with 12 screws around the edge. The presence or absence of pulley screws is the best way to tell a 1-speed from a 2-speed, from a few yards away. If the clutch cover is off, the presence or absence of the manual starting clutch lever is another way to tell. 1-speeds have it but 2-speeds do not.

ColumbiasoloSolo “Colombia” Motor, Type 255

Solo “Odyssey” with Columbia-made clutch and no coolant

Colombia 2240-2250 clutch

Solo 255 with Colombia “belt clutch”.
The sides of the belt are the friction surface.
No clutch shoes, no friction plate or disk.

How the automatic clutch works: The engine is idling and the belt is stationary. The pulley sides are spinning, but the pulley center is not, because it is on a needle bearing. As the engine begins to rev up, the weights #6 fly out from centrifugal force. They force the outer pulley half #8 inward, causing the sides of the belt to rub on the spinning pulley sides. The bike begins to move forward. As the speed increases the weights fly out more and more. When the revs are high enough, the weights are fully out, and the belt is not slipping, or almost not slipping. When the bike slows down, the spring #7 pulls the weights back in, and the slipping process reverses.

How the starter clutch works: A manual start lever on the handlebar pulls a cable, that pulls a start lever #36 against the clutch. It moves a plates #3 and #5 inward. That forces the outer pulley half #8 to rub hard against the belt. Then moving the bike forward, either by pushing or pedaling, causes the engine to turn over, and hopefully start up (if other things are working). When the start lever is released, moving the bike forward has no effect on the engine.

More clutch info: The Colombia “belt clutch” has a needle bearing in the front pulley that allows the belt to be stationary while the engine crankshaft is spinning at idle speeds. Those needle bearings often go out, and bind. Then the bike won’t stay idling unless the rear wheel is allowed to rotate at around 5 mph. The thin needle bearing needs to be greasy, inside, but the belt that goes around it needs to be not greasy.

Another problem is high friction. As explained above, the sides of the belt are the friction surface. The trouble is, the design causes a lot of friction, so you have to push or pedal really hard. The excess friction is from the belt rubbing the pulley sides the wrong way. The belt only moves in a circular motion for half way around, then it moves across the pulley, not with it. Some people are not strong enough to get it started.

Another problem is slippage. The sides of the belt always slip a little, but they slip a lot when greasy. Then you have to pull very hard with your left hand on the start lever. The hard squeeze required eventually leads to the starter pieces wearing out fast. Once that happens, some people end up wrapping a rope around the flywheel to use as a pull starter. De-greasing the belt, and applying sticky spray for squealing belts, should help it to not need such a strong squeeze on the hand lever.

Welcome. Badger mopeds were made by Tovarna Rog, in the city of Ljubljana, Slovenia, formerly Yugoslavia.

 

 

Info Badger

There are many things the same as Batavus (Holland). 

You have to admire the 120 year history, from http://www.secondchanceproject.eu/wp/?page_id=16

Tovarna Rog in 2000's

Tovarna Rog in 2000’s

The long history of the Rog Factory (Tovarna Rog)

The industrial use of the area and the building started in the year 1871 when the Janesch (Janež) tannery started to operate. After 1900, the tannery was bought by Carl Pollak who renovated and extended the factory building, and expanded the production. The rebuilt factory is the first example of (visible) iron-concrete skeleton construction in Ljubljana. The Pollack factory worked successfully until the economic crisis in the 1930s, when the company was placed under compulsory administration of the Municipal Savings Bank, because it was insolvent. The industrial building was in use during and after the Second World War, when the Rog factory started manufacturing bicycles and typewriting machines on site (1952). The last big renovations of the building and the construction of auxiliary facilities were carried out in 1953 and 1963. The Rog factory operated on location until the early 1990s when the bicycle production was closed.

Part of the story that is not verified, was an earthquake struck the bicycle factory not long after the production of mopeds began, in the mid to late 1970’s. The earthquake destroyed most of the moped making equipment, and it was never replaced. So Rog moped production was brief. That is why Badgers are so rare in the US, because they were only made one year, pretty much. 

The abandoned 7000 square meter Rog factory was revitalized as a arts and cultural center in the 2000’s.

Odyssey

June 13, 2015

Odyssey   made in Germany by Solo Kleinmotoren   Solo engine

Odyssey was a USA-only brand, sold by The Odyssey Company, Mill Pond Center, Cos Cob CT 06807, and made in Germany by SOLO Kleinmotoren GmbH, Sindelfingen 6. Kleinmotoren means small motors. Solo made mostly agricultural motors, chain saws, sprayers, etc. Here is a English translation link to German Wikipedia de.wikipedia.org/wiki/Solo_Kleinmotoren, where they explain the name Solo. “Solo” is from the revolutionary backpack portable sprayer for pesticides in 1951. It could be used independently by a single person for the first time, whereas in the past pesticide sprayers required a heavy stationary motor pump and several assistants to handle the long hose. Here is a brief history of Solo from http://www.mopedarmy.com/wiki/Solo:

In a smallsolo workshop, the brothers Hans and Heinz Emmerich began the development of the first small two-stroke engine. At that time, the “lightest” industrial engines weighed as much as 35 pounds. On June 20, 1948, the same day as the Germany Currency Reform took place, the first KMS 30 (KMS = KleinMotoren Stuttgart) engine was born. Intended as a power source for portable machines, the KMS 30 weighed only 14.3 pounds yet produced 1.2 HP, which was an incredible feat for that time. From 1948 to 1971, Solo manufactured various pieces of agricultural equipment as well some scooters and other vehicles. In 1971 they introduced the Solo moped.

 

Solo Regular (1-speed) Transmission, no pulley screws

A. has no pulley screws
B. disk clutch with start lever

Odyssey 2-Speed Transmission
A. has 12 pulley screws

Solo 2-speed first speed clutch

Odyssey 2-speed Transmission
B. has a 3-shoe auto clutch

 

 

 

 

 

 

 

 

How to identify a 1 or 2 speed: There are two types of belt-drive transmissions, 1 speed and 2 speed. The one-speed (ein-gang) “regular” transmission has a solid rear pulley, with no screws around the edge. The two-speed (zwei-gang) transmission has a rear pulley with planetary gears and a second speed auto clutch inside, with 12 screws around the edge. The presence or absence of pulley screws is the best way to tell a 1-speed from a 2-speed, from a few yards away. If the clutch cover is off, the presence or absence of the manual starting clutch lever is another way to tell. 1-speeds have it but 2-speeds do not. See the Solo Motor section for more about the differences between the transmission versions, as well as the speed versions.

 

Solo Odyssey motor

Odyssey Zweigang Solomatic

Zweigang Solomatic

The amazing Solomatic Zweigang rear pulley changes speeds in a step, with planetary gears and an auto clutch inside the pulley, in an oil bath. That is way different from a much simpler variable V-belt pulley that gets wider or narrower continuously, according to centrifugal weights. So the Solomatic is a “true” 2-speed, not a CVT.

Tomos Parts

February 28, 2015

Welcome. ManTomos Logoy Tomos parts are in the Parts By Type sections. Below is a summary list of Tomos parts with links to the Parts by Type sections. The parts are described by sizes, specs, and type rather than part numbers and brand names. This system allows for when the same part is used on several different brands. For example, “Tomos A3 rings” are also “Sachs rings” and “Puch rings”. Instead, here we call those rings “38.0 x 2.0 FG”. That is more technical, but more universal and correct.

This Flag 1list is of United States model Tomos mopeds and nopeds. Tomos began in the US in 1976, but their new A3 moped came out in 1974 in Europe. Before that Tomos made Puchs, under license. 2013 was the last year Tomos sold new USA mopeds. That is why the dates below all range from 1974 to 2013.

Engine Names (all are under two horsepower, two speed automatic with pedals, some with kick start):
A3”   was 1974-1991
“Top end” is cast iron cylinder with piston controlled intake, two transfer ports, aluminum head.
A35” was 1992-2006
“Top end” is cast iron cylinder with reed valve intake, bigger fins, aluminum head says TOMOS.
“Bottom end” has wider gears and clutches, bigger roller clutch, more solid cases.
A55” was 2002-2013
“Top end” is all-aluminum cylinder with piston controlled intake, four transfer ports, aluminum head.
“Bottom end” is the same as A35.
