Who says you need two wheels to have fun on a bike. The SBU V3 is a one wheel bike that can be controlled with leaning motions. You can go faster by leaning forward or slow down by leaning back. This bike runs on electric energy and weighs about 27 lbs. You can go as fast as 15 mph with this. The concept is designed by Focus Designs. It is available for $1795.
