I tried my first backflips today and I think it went pretty well! Didnt actually land them with my feet on the pedals but I was able to do the whole rotation after a feew tries!:P
I remember reading a previous post were u said u were going to try them and then you said you were leaving to go try them, now a biyt later i see this, good job on actually getting the balls to try them and u basically already have them, props.
You're freaking out a little as you go off it. (I'm not suggesting you're afraid) Your body is tensing up. When that happens your dominant side usually kicks the bike out to one side. Looks like that's what's happening. I'm sure you've experienced the dead-sailor kicked to one side. Same thing. Try to relax and tell yourself before you even get to the spot that it doesn't hrt to crash and it's no big deal.
