- Columbia mopeds were made by Columbia Bicycles, which is claimed to be one of the very first bicycle manufacturers in the United States, dating back to 1877. The mopeds even sported the same logo as the bicycle company.
- Columbia mopeds were the first mopeds ever assembled inside the U.S., even though the motor and some other parts were not made there. The tubular frames, seats, fenders, wheels, hubs, brakes, front fork assembly, headlight, and wiring harnesses were made in the USA.
The majority of Columbia mopeds bikes were powered with a 47cc Sachs 505/1A, though some were powered by a Solo motor. Even though the Sachs 505/1A motor is designed for rear coaster-brakes, Columbia chose to use a Magura hand lever and cable for the rear brake.
- There are 2 models that are the most abundant frame types for Columbia, both of which went by the same name of Columbia Commuter.
- The pressed steel frame was Sachs powered only, while the tube frame model had either the Sachs or the Solo motor.
- The top-tank Columbia Medallion, also known as the Western Flyer, is a very unique design for Columbia mopeds. Essentially, the frame of the bike is identical to the tube frame Commuter, but it has a plastic gas tank that reaches from the seat to the steering column.
- The "Western Flyer" name came on all frame types, and is not specific to any model. These bikes were sold under the name "Western Flyer" instead of Columbia.
Columbia = Mopet
At some point in the late 80's Columbia sold rights and design of their moped to a company, KKM Enterprises, Inc. that produced identical mopeds under the name Mopet into the mid 90's. This company produced the tubular frames, long seats, fenders, wheels, hubs, brakes, front fork assembly, headlight, and wiring harnesses in the USA.
