Abstract: A four wheeled, human-powered, striding cycle that uses the stepping and striding motion of the human legs to propel a rider forward. Two separate and dependent foot pedals are moved fore and aft along a concaved arc segment. The motion simulates the natural stepping and striding motion of a running human. A standing human steps on a pedal, then moves it down and aft in a striding motion. As one pedal is moved aft, the other pedal moves forward in a reciprocating fashion. A cable and pulley system connects each pedal with its respective rear wheel. Pedal motion aft applies torque to its respective drive shaft which in turn rotates its respective drive wheel. Pedal motion forward also provides torque to the opposing drive shaft creating additional torque for the opposite wheel. Forward motion begins when force is exerted down and aft on each pedal by the stepping and striding motion of the human leg.
