ABSTRACT:
A pedal assembly for bicycles, velocipedes, and the like is disclosed wherein the pedal is adjustably attached to the crank arm at a predetermined angle of inclination to or perpendicular to the crank arm. Rotation of the crank arm varies the angle of inclination of the pedal; the predetermined angle of inclination is the sum of first incremental angle provided by a beveled cam and a second incremental angle provided by an inclined pedal platform.
Also disclosed is a quick-release pedal-and-cleat structure in the pedal assembly.
