The Motorized Monocycle.

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 (Play Video). 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. (minimum weight of 110 lbs. suggested for proper counterbalance during acceleration and braking). It can run for up to two hours on less than a 1/2-gallon of gasoline. Not a street-legal vehicle. 67" diam. x 14" W. (110 lbs.)
