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. http://www.motorcyclemojo.com/articles/the-uno/
Also, I wonder how far it can go on a single charge, and how long does it take to charge? I wouldn't mind one of these for commuting on nice days.
The controls consist of leaning forward and backward, therefore there is no manual shifting. If you've ever seen a motorcycle with a (rudimentary) auto transmission, they are obscenely huge. This thing as half the size of the smallest sportbike I've ever seen, so it does not have space for an automatic tranny.
It's basically a Segue styled to look like a unicycle.
