hi , i really don't know why i cant kickflip i can fakieflip nearly every time and into advanced grinds (krooked,smith ect)
but i fust can to them normal. do you know why?

Because it's much easier to pop when you're rolling backward. Just stopping it rolling backward - the stopping of the momentum gives you good pop. It's much harder to learn to pop tricks going forward because you have the opposite momentum.

thanks i will try that
