Unocycle or simply Uno is designed on a one-wheeled motorcycle concept that probably looks like a motorcycle that has been in a nasty accident, but the teenage (18-year-old) inventor of this electric bike, Ben J. Poss Gulak from Canada, believes that this is the answer to urban traffic chaos and pollution. Although it resembles a unicycle, the Uno has two wheels side by side and uses gyroscopic technology to stay upright. The rider leans forward to accelerate to speeds of 15-20mph, and backwards to slow down. The inventor states that he was inspired to make the bike after visiting China a few years ago and seeing all the smog there. They all drive little bikes that are really polluting and he wanted to make something to combat that and the final product of his several years of research is Uno. The Uno weighs around 120 pounds and is light enough to be taken indoors to be charged up and run for around 2.5 hours.  Still in development, the Uno's top speed is said to be around 15-20 mph, but the inventor, Ben Gulak, suspects it could be made to go as high as 40 mph. That's no Harley, but it's still faster for a unicyle, and remember this is a battery-powered machine that you never need to fill up.
