Abstract
A pedaled propulsion system has left and right foot pedals that travel up and down on roller slides on track members mounted on the bicycle frame. An endless drive web passes between the pedals and loops around a driven wheel at one end of the track assembly, and around an idler at the other end of the track assembly. The driven wheel is mounted on the input shaft of a unidirectional transfer arrangement. The transfer arrangement has an aluminum block case or housing, and an input shaft which has a bevel pinion gear on it that meshes with left and right driven bevel gears. These bevel gears each are mounted to an output shaft by means of unidirectional clutch bearings inside the bevel gears. Each bevel gear drives in one direction and idles in the other direction. As the input shaft oscillates back and forth, the output shaft continues to rotate in the same direction. A sprocket wheel can be mounted on the output shaft to power a chain drive or a shaft drive. Springs at the bottom of the pedal stroke cushion the stroke and return some of the energy during the return stroke.
