As a bicycle front forks protrude downwardly from the headstock and support a front wheel driven by pedal cranks, and rear forks are cantilevered downwardly and rearwardly from the central unitary frame. As a tricycle the rear forks are replaced by a frame supporting two side by said rear wheels. Handle bars protrude upwardly from the headstock and an elongate inclined seat protrudes rearwardly and upwardly from the headstock. The velocipede is simple, compact and may be ridden by riders of different sizes without adjustement.
