I think I've seen one of those around but on a pavement. I thought it was...well I didn't know what it was. I knew it wasn't a childrens toy because a full sized adult was on it, but I guess it reminded me a bit of one, hehe though i guess its a bike version of the quad... but much smaller
By the way on the pics up there, it looks way small with you/someone on it, but yet propped up near a bench, it looks rather big...Is that a bench from a dolls house?
Am joking by the way, looks really kewl. Speeds are very fast too!...though you wouldn't get me on one
