Thanks for all your guy's help on my last questions. The answers were more than helpful. I was looking for tips on jumping and hopping. I'm on a 20' and I can't seem to get any height out of my jumps. I've inflated the tire well enough but I can't get the motion to jump any higher than one stair at a time. On top of this, I was wondering how you get any distance out of your jumps. I suppose you must be moving in order to get max distance, but is there something I'm just not getting? Thanks in advance. -NiGGeL
