This is the only four-wheeled rowing cycle that is available in this universe. The four-wheeled rowing cycle is propelled forward by rowing with the handlebar, which transmits power to a chain-driven gear centered on the rear axle. It combines the full-body workout of a rowing machine with the exhilarating ride of a recumbent quadcycle, enabling one to complete a fluid stroking motion that exercises the heart, core, and limbs amidst ever-changing scenery and outdoor terrain. Accommodates riders 4′ 3″ and taller (up to 300 lbs.).
