Abstract
Abstract A shoe brake for the rear wheel of a juvenile bike is pedal operated by a cam wheel on the pedal crank and a connecting link between the cam wheel and brake shoe. When pedalling forward, a spring keeps the brake disengaged, but upon reverse pedalling the spring allows the cam wheel to energize the brake shoe through the connecting link.
