Pope began manufacturing motorized bicycles in 1902 and continued with motorcycles until 1918.
Columbia mopeds were the first mopeds ever assembled in the United States, even though the motor and some parts were outsourced. The tubular frames, seats, fenders, wheels, hubs, brakes, front fork assembly, headlight, and wiring harnesses were made in the United States.
The majority of Columbia mopeds 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 two 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 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.
In the late 1980s, Columbia sold the rights and design of their mopeds to a company, KKM Enterprises, Inc. that produced identical mopeds under the name Mopet into the mid-1990s. This company produced the tubular frames, long seats, fenders, wheels, hubs, brakes, front fork assembly, headlight, and wiring harnesses in the United States.
