It's how he rolls

Can't afford a Segway? The Solowheel is only $1,796, but you get only one wheel.

The description at solowheel.com says:

The Solowheel is the smallest, greenest, most convenient "People Mover" ever invented. This gyro-stabilized electric unicycle is compact and fun to ride and is intended to be used as you would use an electric bicycle.
