Drawing upon a robust history of development that began with an original design conceived in Marseilles, France in 1869, this is the motorized monocycle made in the Netherlands that propels a single rider up to 25 MPH. Powered by a 31cc, four-stroke 1 1/2-hp engine, the wheel operates by using a centrifugal clutch on its inner steel frame to engage the larger 67″ diam. outer flywheel that actually makes contact with the ground with a rubber tire. The ingenious device is steered by leaning to one side or the other, and it can safely negotiate any dense surface such as pavement or grass. A fiberglass frame encloses the engine, drive train, and fuel tank, and provides a cushioned seat and convenient footrests for riders up to 6′ 3″ high when in a sitting position. The hand-holds have a finger throttle that provides progressive acceleration and a brake that provides confident stops for riders up to 275 lbs.
