It's a Motorcycle! It's a Unicycle! No, it's Uno!

"Uno: a Unicycle-Motorbike-Segway Hybrid"

Take a motorcycle.

Remove both wheels, and but them side-by-side, under the rider.

Give it gyroscopes and limited AI.

Add snappy styling and a bright paint job.

That's the Uno. It's a sort of motorized unicycle. You make it go, turn, or (I assume) stop by leaning one way or another.

It does have one control: a power switch.

Very, very impressive.
