just giving kinda an update and tips on what i am learning fopr anyone who saw this post adn started trying this too. i am practicing doing the trick on just flat ground by grabbing the front brake and doing a footjam. once i get the front end high enough i give the tire a good kick back to get momentum and get the bike even higher in the air. one thing i found out that helped alot thou is when you are first getting the rear of the bike in the air, keep the foot that is still on the pedal flat to the ground. when i first started doing it my left foot (the one on the pedal) would not be flat to the ground, so when i started going backwards my foot would change postion and kill my balance.
