Looking a little bit like a 50′s Vespa mated with a 21st century robot, the Electric Unicycle is a lot like a Segway, except where it isn’t. It is a gyroscope-balanced personal mobility device with a 500W motor that can push a 160lbs man at 13mph for up to two hours on a three hour charge. But unlike the Segway, this one has one wheel. So while your forward and backward movements are gyro-controlled (and serve as the throttle), your side to side movements aren’t; you will have to have some sense of balance or you’ll fall. It shouldn’t be that hard though, and once you get the hang of it, you’re sure to get a lot of enjoyment out of your $2,700 expense.
