ABSTRACT:
In a bicycle pedal mechanism, the pedal is floatingly mounted on the pedal axle by means incorporating a cam mechanism whereby the pedal is caused to shift longitudinally to and fro in synchronism with the rotation of the crank. In this way the rider's feet are positioned to do useful work for a longer duration of a cycle than would otherwise be the case.
