what are you struggling with particulary?
i had poblems to get the backwheel right on the spot the frontwheel was before(if that makes sense),and i figured out it helps alot to lean over the bars even more,so you get this"going over the bars feeling" just for a split second,then release the front brake and extend legs,while pulling the bars in "rear wheel stance" position(arms bent).
edit:or did you mean just hopping to front?title is a bit confusing sry
