ABSTRACT:
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.
