Abstract
The present invention relates to a rider's simultaneous use of his forearms/hands and legs to provide dual power into a propulsion system for riding a cycle vehicle, including a bicycle and a tricycle, or other vehicles. The invention permits the rider to have complete control turning the cycle vehicle, at will, right or left, while at the same time pumping a set of forearm/hand bars in an up power stroke and a down power stroke. In addition, even though the pumping action is lineally moving a telescoping rod and a push/pull cable back and forth, it is also simultaneously rotating a flywheel, upper and lower sprockets, and the crank axle to drive the bicycle wheel forward over the riding surface. Thus, the rider can provide maximum power into rotating the rear tire by simultaneously using both his arms and legs, while contemporaneously controlling his direction of travel.
