Hi, I have only just learnt to bunny hop , so i feel your pain.. I found that just ride along at slow speed, and try to flick the back wheel up in the air, by just throwing your weight forwards, but don't jump, which is a problem I had. Then when you can do that motion, add in, the lift of the front wheel and the back should follow. But just stick with it, I took quite a few falls before i could do it. Joe
