Audi A0

The Audi A0 concept, developed as a joint collaboration between Technische Universität München and Universidad Nacional Autónoma de México, combines an electric motor with a single, hollow wheel for a self-stabilizing, tilt-controlled stroll.

At a maximum speed of up to 15 km/h (9 mph), this monocycle can be folded up to fit in your car’s trunk for a casual ride around the great outdoors.



Don’t expect to get too far on that sightseeing trek though, as the cycle’s battery only lasts for up to an hour.
