ABSTRACT:
A drive system for the application of rectilinear drive force, wherein the rectilinear force is converted to a rotational force. The apparatus employs power blocks which are slidably mounted upon opposing parallel rectilinear motion guides. The power blocks are connected together and are disposed at opposite ends of the apparatus. Connected to each of the power blocks is a power transference chain which rotates an idler sprocket and a power sprocket when force is applied to the power blocks. The idler sprocket rotates in both clockwise and counter-clockwise directions, while the power sprocket coupled thereto applies force in solely a clockwise direction and is disengaged from its mounting axle by a unidirectional clutch when rotated in a counter-clockwise direction. The power sprocket applies a force to the drive resistance point, which in the case of a bicycle comprises the rear wheel thereof.
