It takes a special kind of magic to make an electric one-wheeled motorcycle not terrifying to ride, and Ryno Motors has pulled it off. The microcycle, which has a single 25-inch motorcycle tire and reaches speeds up to 10 mph, uses a combination of gyroscope sensors and accelerometers to balance itself.

I saw this when I lived in Portland OR and it looked very interesting – if just as dorky as a Segway. If they were legal in your town, would you buy one?
