Adam Savage rides his electric unicycle thingee

Via Bikes and the City. This is a video of a motorized unicycle called an SBU, by Focus Designs, with Adam Savage behind, or on, the wheel. These are cool! I had never heard of them.
I can never personally justify electric bikes and light EV's. I can ride faster, all day, with my own power. So it stays at "neato" for me, not a must have.
