ABSTRACT:
Manually powered propulsion apparatus includes a pedal and a rotatable member. A flexible transmission member is connected to the pedal and to the rotating member and includes pivotally interconnected link members. The link members are linearly disposed when the pedal is extended and cooperate to form a curved, self-supporting structure between the rotatable member and the pedal when the pedal is retracted.
