power cagesA bicycle pedal provides the connection between the cyclist's foot or shoe and the crankarm allowing the leg to be used to turn the crank. The Velocipede, a predecessor to the bicycle, lacked pedals but allowed the crank to be operated by means of a treadle. Pedals were initially attached to crankarms connecting directly to the driven (usually front) wheel. The safety bicycle as we know it today came into being when the pedals were attached to a crankarm driving a ring gear that transmitted power to the driven wheel by means of a chain.

Although the pedal turns clockwise in its bearing relative to the crankarm, the force from the rider's foot presses the bearing against the crankarm thread at a point which rolls around clockwise, thus slowly pulling the outside of the bearing anticlockwise because of friction. Flat & PlatformWell-Go Platform PedalsTraditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contrast to the quill pedal which had very little surface area. One form of the platform pedal had a large flat top area and flat bottom with large "flip-up" tabs for use with toe clips and toe straps designed for greater cornering clearance, which was often needed on the track.
