Rider sits sideways, so the same balance system is used as is used in skateboarding, surfing, snowboarding, etc. (opposed to the left-right balance on typical 2 wheelers).
The videos are boring as hell, all the guy ever does is go around in circles, mostly. But, the idea is interesting.
Looks interesting. Doesn't look as stable as bike though.
Well uh... it's "cute" Having to stay seated(I doubt you could easily stand and pedal) which would make suspensionless travel on un-perfect pavement..shall we say, "A real kick in the crotch"
