Cheers Bottleneck, I think im pulling the bars too high too early.
I ride a 09 GU Le 20" but used to ride a 26" which i found this move to be easier on. It took more effort to lift the front wheel in the first half of the move which probably helped in a way. With the 20" it feels far more sensative to giving it too much on the pedal stroke at the wrong time.
I haven't had much luck with bunny hops so far. I see its far more popular with benito ros and others at world cup level. I can bunny hop my mountain bike pretty well but it feels totally different on the trials bike!!?
