Practise backrolls. Try it at quaterpipe or something. Also, watching my wheel helped me to do back rolls. But DONT start to jump, it might feel easy but it looks horrible.
yeah what Tupsu said, DONT do fakey hops. i can fakey 10x longer than i can manual, and its just all from practicing . go in a huge ppip and go up it then don't 180 and kep rolling back down and keep repating that
