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.
For use with a bicycle having a frame with a hub-forming casing, front and rear wheels supported on said frame, a pedal crank assembly having a shaft extending through said hub-forming casing and projecting at its ends therebeyond and pedal cranks provided at each end of the shaft, and front and rear wheel caliper brakes, the improvement comprising a brake control assembly having a cam mounted on said shaft for rotation therewith and having at least one cam working surface, a plate carried on said shaft for limited swingable movement with respect thereto and being in substantially planarwise parallel relationship to said cam, a brake control cable extending from each of said front and rear caliper brakes, a link having an upper end portion operably secured to said brake control cables, said link having a lower end portion engaged to said plate, a cam follower pivoted in its rearward portion upon said plate and having a forwardly extending free end forward portion engageable with said at least one cam working surface upon back pedalling whereby such engagement effects a limited rocking of said plate with consequent downward movement of said link to effect pulling on said brake cables for bicycle braking action.
