SBU always in balance
The Self Balancing Unicycle is a unique blend of machine and human balancing. Lean forward to speed up and lean backward to stop. Its top speed is about 8 mph on a flat road. Do not lean too far on the Self Balancing Unicycle otherwise you’ll fall of.

On a single charge you can use the SBU almost 1.5 hours. Only ten Self Balancing Unicycles will be sold early November 2008, for $1500 a pop.
