not sure exactly how you're supposed to ride it. looks otherwise like the kind of small two wheeler that interests me, because you can easily take it place that would be difficult or impossible for anything with four wheels instead of two. i just wish, something that proportioned could be nearly silent to not chase away little furry creatures i'd be there to see. or to get to and from a camp site. something like that but all electric. better then two wheels would be anti-gravity, and quiet, but of course we don't have that. as for all that loud high powered stuff, i really wouldn't want to ride on two wheels in mixed traffic with cars and trucks anyway. or any more then i would need to to get to where only two wheels can.
Trials is a competition where in you navigate a course. If you touch your feet to the ground you loose points, speed is not a factor. So, if you notice a trials bike has no seat as you never sit.check this guy out....
