When I started, I would put my front wheel up on a curb or pallet and practiced lifting up my rear wheel and rolling on, really exaggerating the rear wheel lift until I could do a front/rear wheel switch on the edge of the curb. This just helped with body postion, I found my body weight had to be quite far over my bars. Once you start gapping to front wheel, keep your arms locked when your front wheel first lands on the object and really bend your knees to pull your rear wheel up. Be careful, you don't want to catch your front wheel on the object and go over the bars. Dallas
