A cycle that uses both arm and foot motions to drive it. Unlike other designs that connect the hand and foot movements to a single crank mechanism, the instant design uses two sets of gears that are stacked. Four straight toothed racks are positioned between the drive gears. The toothed racks are connected to the hand and foot levers so that as the levers are manipulated, the racks are moved back and forth. This reciprocating motion turns the gears, transferring energy to the main drive gear, which turns the wheels. The drive gears are paired so that one set is always providing power from each operating lever. The operating levers are designed to alternate-i.e., left hand forward left foot back at the same time as the right hand is back and the right foot is forward. Thus, with each stroke, power is transmitted to the wheels.
