ABSTRACT:
A four wheel velocipede includes a single front to rear frame member connected to front and rear axle assemblies. The steering mechanism is coupled to the front axle assembly by a pipe braced to the frame member. In one embodiment, the frame member is bent over to one side and contains a drive linkage driven by a pedal operated crank assembly connected to a central cantilevered pipe for driving a rear wheel. In a second embodiment, a front wheel drive includes universal joints connecting the front axles to a pedal driven crank for permitting the front wheels to be driven while simultaneously steered. A horizontally extending cross member crank pivots about a vertical axis on the frame member for driving the pedal driven crank via a pair of reach arms connected to the cross member crank.
