ABSTRACT:
Manually-powered propulsion apparatus for propelling a cycle includes two pedals and two rotatable crank members connected to the drive wheel of the cycle. Two flexible cables are connected to the crank members, one of the cables transmitting power from the pedals to the crank members and the other cable causing retraction of a pedal when the cyclist is applying force to the other pedal.
