Hi, I need help with bartwist, I've not even tried one propely yet, I can't get the motion right. I can the motion when the scooter is on the floor but if I pick the front wheel up, my hand gets stuck on the grip. Its so annoying, I've tried wetting my hand to make them slide around the grip better but I want to be able to do it without it, any tips on how to slide your hand around the grip?
