But when i'm trying to bunnyhop or whatever it's called I can't the scooter up ?
If the average scooter rider's IQ was any lower that it already is, most of us would be smashing ourselves in the face with rocks right now.
If your clamp is too heavy, then you have a problem. Work out or something. Ultra pro clamps are the lightest out there. Plus, the weight of a clamp is inconsiderable. It doesn't change the feel of the scooter or anything, for the most part(except for SCS and some quad clamps). I'm going to assume that you just don't know how to jump properly.
