A motorcycle with one wheel? No, it just looks that way. The Uno has two wheels, side by side. It runs on electricity and is controlled by body language. The only controls are an on-off switch. To go forward, you lean forward. Lean further to go faster. The Uno was invented by 18-year-old Ben J. Poss Gulak. Motorcycle Mojo has the story of how the Canadian engineering prodigy built the prototype Uno. Link
