- 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 1843. The mopeds even sported the same logo as the bicycle company.
- Columbia mopeds were the only mopeds ever assembled inside the U.S., even though the parts and motor were not made there.
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 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.
- Some models of the "Western Flyer" use the pressed steel frame of the Commuter, and are indistinguishable from each other but for the decals on them.
Columbia = Moppet
At some point in the late 70's and early 80's Columbia sold rights and design of their moped to a company that produced identical mopeds under the name Moppet.
