Abstract

A bicycle having front and rear wheel caliper brakes, a pedal crank assembly having a shaft extending through a hub and projecting at its ends therebeyond for connection to pedal cranks. The shaft may be integral with the pedal cranks or may be discretely formed and threadedly secured at its ends to the pedal cranks. The bicycle also contains a brake control assembly having a cam mounted on the shaft outwardly of the hub for rotation with the shaft, the cam having at least one working edge surface, a plate carried on the shaft in substantially planar parallel relationship to the cam. The plate pivotally mounts a cam follower, in the nature of a pawl, for engaging said cam working edge upon back pedalling operation. A substantially vertically extending rod is loosely engaged at its lower end to the plate and fixedly engaged in its upper end portion to brake control cables leading from the caliper brakes. The rod is journalled for axial rotation and resilient means urges the same into spaced relationship with respect to the cam follower with which the rod is engageable upon rotation for releasing the cam follower from engagement with the cam.
