The Solowheel from Inventist, Inc. is simultaneously an advanced form of low-energy, zero-emission, ultra-portable transportation and a modern version of Thor’s prehistoric wheel from “B.C.” Not that self-balancing people movers are anything new, even in modern times.

The best known product in this category is the Segway. The main difference between a Segway and a Solowheel is size. The Segway has two wheels and a long handle for the “driver” to hang on to. By contrast, the Solowheel is just what it sounds like – a single wheel, but one with a small handle on top so that when you’ve finished using it for transportation, you can pick it up and carry it with you.
