Abstract: A detachable pedal assembly including an axle assembly and a binding assembly with an automatic release mechanism is disclosed. The axle assembly includes a thrust bearing and threads to engage the crank. The binding assembly includes a pedal and clasp that detachably receives and locks the thrust bearing of the axle assembly in operational engagement. When a predetermined force is applied the binding assembly automatically releases from the axle assembly to permit the cyclist to dismount or avoid injury in an accident. Furthermore, the position of the release mechanism to the side of the binding assembly permits the binding assembly to be offset from the axle axis, thereby improving increased riding efficiency, lower aerodynamic drag, and increased turning clearance.

Abstract: A detachable pedal assembly including an automatic release mechanism that is positioned approximately between the pedal and crank arm is disclosed. The detachable pedal assembly in one embodiment comprising an axle assembly including thrust bearing and threads to engage the crank, a binding assembly including a pedal to which the cyclist applies force and clasp that detachably receives the thrust bearing, and a force-sensitive locking means that holds the binding assembly in operational engagement to the axle assembly until a predetermined force is applied, at which time the binding assembly automatically releases the axle assembly to permit the cyclist to dismount or avoid injury in an accident. The position of the release mechanism to the side of the binding assembly permits the binding assembly to be offset from the axle axis, thereby improving increased riding efficiency, lower aerodynamic drag, and increased turning clearance.
