ABSTRACT:
An apparatus for changing the leverage of a bicycle pedal by telescoping the pedal on the pedal arm during rotation of the pedal arm and pedal guide around the pedal axis; the apparatus comprising a pedal guide which includes a lead bolt and has the pedal attached thereto, a pedal arm, a cam plate, a cam ring, a ring bearing, a pedal axle, a sprocket, and a spindle housing. The lead bolt of the pedal guide rotatably attaches to the cam ring which peripherally encloses the ring bearing. The ring bearing is peripherally located around the cam plate thus enabling the cam ring to rotate with respect to the cam plate. As the pedal arm and pedal guide rotate, the cam ring and cam plate control the telescoping motion of the pedal and pedal guide by controlling the movement of the lead bolt of the pedal guide. The pedal guide slides on the pedal arm. The sprocket is fixedly connected to the pedal axle.
