How do you get all 4 wheels on the wall?
it's not hard, try doing a kind of ollie when you "hit" the wall, stay with skate in your feet ! do it many times and you will do backside allride! see in my profile ! I hope my tip help you!
Soon as you ollie, put your hand against the wall and use it to drag your feet and the board up the wall
Put your feet even on the board and push towards the wall
