Self Balancing Unicycle
The SBU is a unicycle that keeps itself in balance. This Self Balancing Unicycle controls the forward and backward balance while you only need to balance to the left and right. There is no need to pedal on the SBU, just use the foot rests.

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.
