Shane Chen calls it the Solo Wheel and says it's the world's first and smallest self-balancing unicycle.
You don't need to pedal, and it goes up to 12 miles an hour. A single charge will keep you rolling for about an hour.
To get going, you simply lean forward and the Solo Wheel does the rest. Chen says most people get the hang of it in about an hour.
The creation should be on the market in about two months, and Chen is already taking orders.
