The third version of the Inmotion Electric Unicycle is here, and it's a much smoother experience than the rest of the self-balancing unicycles we've used in the recent past. Which is silly to say because it's not like we use self-balancing unicycles all that often - or ever. Inmotion basically has the market cornered. Here at CES 2015, at least, there's really nothing like it. Riding around on a unit that lets you turn with a flick of your hip - that's the future of one-wheeled transportation.
