Abstract
A bicycle wherein the front wheel can be both steered and powered by reciprocal movement of the handle bars in a forward and rear direction. The drive system for the front wheel comprises a first linkage comprising two arms, one of which is a pivoting arm, and a second linkage comprising three arms, two of which are pivoting arms. The two arm linkage system is the primary driver in the sense of rotating a drive sprocket between two over center positions. The three arm linkage system, while also driving the drive sprocket, serves the primary function of moving the two arm linkage system over the two center positions, as the handle bars are reciprocated in forward and rear directions.
