A bicycle having front and rear wheel caliper brakes each being connected by a cable to a linkage including a swingable cam element which is normally disposed in the path of travel of a cooperating cam member mounted for movement concentrically about the pedal axle whereby the cam element through its swingability is removed from such path during forward pedaling action and is lockingly engageable with such cam member upon back pedaling action. In the latter condition force is applied to the linkage for effecting a pull upon the cables to effect braking operation. The cam members are so related to the pedal cranks that when engagement with the cam element is effected one pedal crank will be downwardly directed whereby a support stand carried upon the associated pedal may cause such pedal to swing to present the support stand for engagement with the support surface.
For use with a bicycle having a frame, front and rear wheels supported on said frame, a pedal crank assembly with a main shaft and pedal cranks, and front and rear wheel caliper brakes, a brake control assembly comprising an elongated latch link disposed proximate said main shaft and having forward and rearward end portions, a lever arm having opposed ends, said lever arm being swingably mounted at one of its ends on said frame, said lever arm at its other end being pivotally engaged to the forward end portion of said latch link whereby the latter is permitted limited movement in a direction generally rearwardly of said bicycle by virtue of the swingable mounting of said lever arm, means connecting said front and rear brakes to said lever arm between its ends, means urging said lever arm forwardly from its swingable mounting when said brakes are in non-braking condition, a cam provided on said latch link in its rearward portion, cam support means mounted on said main shaft for rotation thereabout, at least one cam follower mounted on said cam support means for movement therewith, said cam and cam follower being unengaged during forward pedaling of said bicycle, said cam and said cam follower being engageable upon back pedaling of said bicycle whereby said latch link is caused to move in said generally rearward direction causing tension to be placed upon said brake connecting means thereby effecting braking action, and means engaged to said latch link for disengaging said cam and cam follower to release the bicycle from braked condition.
