Each side frame comprises a single length of tubular material of substantially constant cross section throughout with the ends of the single length providing vertically spaced free ends. A seat mast having a crank housing tube connected to the lower end thereof has its upper end joined to the pair of frames. A fork mounting tube of substantially constant diameter is provided between the frames, and a fork assembly is mounted for pivotal movement about the axis of the fork tube in a manner in which it can be quickly disconnected from the frame. Dropouts are in the free ends of each side frame and the ends of fork tubes of the fork assembly, and a wheel is rotatably mounted on the dropouts.
