How this thing works really is a mystery. It looks more like a killing machine than a high-tech motorcycle.
The RIOT Wheel is a huge, heavy motorized single-wheel vehicle, originally built for Burning Man, the natural home of deviant vehicles. RIOT 2 and RIOT 3 are the next incarnations, still somewhat under wraps. What we can say about them is that they are both much lighter. RIOT 3 is an all-out speed machine for claiming the world single-wheel land-speed record, RIOT 2 is a highly maneuverable, practical about-town vehicle.
