That's actually pretty darn cool. Not that I'd be rushing out to get one, but still.
Always thought that if Kamen could do the Segway, why not a two-wheeled, inline version, without the handlebar stalk? So basically a Segway skateboard, but single track with lateral stability built into it. I'd not ride a Segway, but I would so love to try this solowheel and would jump at a chance on the two-wheel-inline contraption I just described.
I know next to nothing. I am frequently wrong.
