Comin’ In on a Wheel and a Prayer: This is what happens when you put an engine on a unicycle. Well, this and massive internal injuries. Because, you know, unicycles just weren’t unstable enough already.
Vaguely resembling a sporty motorcycle, the uni-wheeled Embrio uses electronic and hydrogen-fuel-cell technology to help its driver zip around obstacles. A system of gyroscopes keeps it upright. In standby mode, a pair of extra wheels deploy jet-plane-like landing gear to increase longitudinal stability.
I don’t quite get it. What is the value of having one wheel over two? This doesn’t strike me as a great advance over the motorcycle.
