Presenting the Uno.

Built by Ben J. Poss Gulak, it’s an electric vehicle that uses a similar sort of microgyro-motor system as the Segway, but with two gyros: one for forward and back, and one for turning. Its got just one control —a power switch— and everything else is done by leaning, which must make for one hell of an adrenaline-packed ride.
