i dont know if you jave ever skateboarded or rollerbladed alot on transitions... like quarter pipes or mini ramps, but there if you have you will be familiar with pumping.
as you ride up the lip you want to pump up... as if you are riding up a quarter pipe. dont fully extend though, pump enough to get your center of balance parralell to the top of the lip.
you need a little bit of pop to get yourself upright, and that momentum should carry you forward just enough to match the angle of the landing.
