Unlike other motorcycle manufacturers of the day, Harley-Davidson did not start out as bicycle manufacturers. Companies like Silver King, Schwinn, and Indian produced bicycles first before moving into the motorcycle market. All Harley-Davidson bicycles were assembled in Milwaukee at Juneau Ave and had unique badge emblems on the head tubes and a gear wheel design with the letters H and D as part of the casting. Bicycles came in one color, military drab, with detailing in black, gold, and white. Harley-Davidson produced bicycles for four years before they ceased production in 1921.
