ABSTRACT:
An O-ring is mounted to the wheel of a manually powered bicycle. A Teflon washer is mounted on the wheel sprocket contacting the O-ring. The friction between the O-ring and the Teflon washer are sufficient to move the crank sprocket away from dead center on a mechanism wherein the crank sprocket is rotated by manually oscillating the handle bars of the bicycle.
