hi guys, I've just recently started back hopping. My best is about 10 hops at the moment, and what i learnt was if you lean back but with bent arms(just a little bit) and keep springing your legs it works just fine. Well it did for me. Oh and one more thing, doing really big hops on the back wheel wears you out a hell of alot more, so keep the hops minimized! hope I helped
