A monowheel or uniwheel is a type of one-wheeled, single-track vehicle. Unlike the unicycle, a monowheel consists of a large, hollow wheel that loops above and around the driver. Monowheels are typically powered by an engine as with a motorcycle, with a chassis securing the steering, driver's seat, and propulsion mechanism to the interior of the wheel.
