Uno

18-year-old Ben Gulak is the inventor of Uno. It took him several years but the result is stunning. Uno has 2 wheels positions next to each other making it look like a unicycle. It works like a Segway, tilt forward to go forward and back to slow down or stop. Ben says he was inspired when he had visited China and saw the pollution. Uno weighs 120 lbs, has a top speed of 25 mph and a range of about 2.5 hours. Ben is currently looking for investors to put the Uno into production.
