Two-Wheeled Unicycles

A YOUNG inventor has created a motorbike with a twist—it uses two wheels positioned right next to each other giving it the illusion of being a powered unicycle. Ben Gulak has spent several years building his electric Uno.

The bizarre-looking contraption has only one switch—on or off—and is controlled entirely by body movement. The rider leans forwards to accelerate to speeds of 25 mph and back to slow down.

The wheels are completely independent, allowing the bike to turn on a sixpence. The bike has a ‘neutral point’ so that when you lean forward it accelerates to keep the neutral point in the right place. It has a couple of gyros and is basically self-balancing.
