ABSTRACT:
A pedal drive mechanism for a are vehicle. In a preferred bicycle version, pedal lever arms Additional pivotally attached to each side of the frame near the rear wheel hub for reciprocal rotation within a limited angular sector. Downward forces exerted by a rider on the pedals are transmitted through flexible tension members on each side of the bicycle anchored either to first attachment points intermediate the ends of the lever arms or to second attachment points on the frame above the lever arms and leading around pulleys mounted at the other of the first and second points. From the pulleys each tension member leads over and around a corresponding rotary driving member that is connected through an overrunning clutch to the rear wheel. Means interconnecting the lever arms return one arm to the upper starting position while the other arm is in the downward power stroke. Manually operable control means vary the location of the first attachment points on the lever arms to change the torque delivered to the driving members for a given driving force on the pedals. Additional idler pulleys mounted at the tension member anchor points may be used to "gear up" the mechanism for higher speeds and lower output torque. Disconnect means disengage the overrunning clutches from the rear wheel hub to prevent damage to the mechanism when the bicycle is backed up.
