I have been trying to improve my bunny hop so that I can do more tricks, and I need some advice. Whenever I see people who can hop higher than me, they pull their front wheel real high. Also, they bring their butts way back behind their seat. I can get about 2 1/2 feet, but I dont do either of those things. How do I do so without falling back or coming off my pedals? Also, it feels like I'm landing way to hard. When I come down, I kind of get shell-shocked, and it seems like some part of my bike kind of clangs. Maybe I just need to work at it more, but any advice would be greatly apprectiated. Thanks.
