They are a blast to bomb hills with but like rob said it is fairly difficult to push from a dead start on flat ground. Also it feels more like a snowboard as you speed up.
Rob, did you have trouble at first with riding? I kept thinking longboarding or skateboarding, not snowboarding and it wont ride like a skateboard. I had to get over this mental block and remember snowboarding not skateboarding.
Np3 once you get good though it is a blast. We have this one hill we bomb and its like a mile and a quarter. So much fun. Its funny to watch people look at you funny tryin to figure out what the heck your doing.
