SBU V3 Self Balancing Unicycle

We know what you’re thinking: when am I going to be able to commute to work on a motorized, self-propelled unicycle with a training wheel? Well, at least you’re thinking it now. So try out the SBU V3 Self  Balancing Unicycle ($1,800). The  SBU V3 works like a Segway and responds to your bodily tilt while providing motorized propulsion and built-in balance. [source]
