erm, i can't explain it but.. just try this to get urself started; ride, then hit ur front brake and as ur coming down lean back so u get ur front wheel in the air, then keep hold of your braken just bounce, lol. That's what most of my friends did to learn how to do. I've never been able to explain this to some one( but i tried ), it just came natural to me, after watching lots of people doing it and getting my ballance on my back tire.
