If you love turning heads when you take a ride around town, then the Ryno electric unicycle is probably for you. Designer Chris Hoffmann had his eyes set on the Segway crowd when he started work on the Ryno, and he has come up with quite the interesting looking one-wheeled auto. The cost for a pre-production Ryno is a whopping $25,000 and Hoffmann already has five orders, but he expects the market model to cost about $3,500. The production model will have a top speed of 25 mph, a range of up to 30 miles and an impressive 25-inch thick tire. Hit the jump for video proof of this gadget in action!
