Abstract: The embodiment of a torque multiplying mechanism, consisting of a rotating sleeve (9), a pedal extender arm (2), small sprockets (5), a hinge pin (4) attached to each small sprocket and to each pedal extender arm, un-numbered short chains connecting the small sprockets to large sprockets (6), and foot pedals attached to the pedal extender arms. The foot pedals connect the pedal extender arms to the rotating sleeve through the small sprockets, short chains and large sprockets attached to the sleeve. The rotating sleeve then forces the vehicle drive sprocket to turn, with multiplied torque, due to the leverage applied to the short chains by the small sprockets attached to the pedal extender arms.
