Abstract
A drive mechanism for a pedalled vehicle employs foot levers mounted on the vehicle frame, a rotary drive mechanism, and one way rotary members. A chain or toothed rack can engage the rotary members to provide reciprocal oscillatory motion, which is then converted to one-way rotary motion. A synchronizing mechanism ensures that motion of each lever produces corresponding motion in the opposite direction by the other lever.
