Focus designs have taken the general premise from the Segway (accelerometers and gyroscopes) to make a self-balancing unicycle (SBU). You control the SBU by leaning in the direction you want to go… the pedals are not actually used for pedaling.
The SBU is not cheap… it will set you back $1,500 and will be available in November 08.
The rider controls the speed by leaning forward or backward to speed up or stop. There is no need to pedal, in fact there are no crank arms, just foot rests. The SBU keeps upright by utilizing advanced electronics including accelerometers and gyroscopes with sophisticated balancing algorithms. It’s truly an experience like no other.
