The parts of the mechanism imitate a real steam engine. The lack of an outer shell grants easy access to the rubber-band motor.
Mode one with the feet locked will allow the Monowheel to roll straight ahead for about 1.5 – 2 meters.
In Mode 2 with the feet in the unlocked position your Monowheel will roll ahead while the rubber-band motor is working. After that it turns around, its feet hide inside and the model keeps rolling until it runs into an obstacle. In this mode, the model can cover up to 5 meters, which inspired us to play some mechanical bowling using our new model as a bowling ball!
