I'm pretty terrible at backwheeling things, so use this rolling get up quite a bit. I call it a "UCI get up" ^_^
I do it pretty similar to explained above, by rolling towards the object, bad foot forward, at an average pace. When I'm within reach, I put in half a pedal stroke to lift the front up onto the object. The idea is it lands on the top, not on the edge and as soon as it does, kick the back wheel up, like the end of a bunny hop, unweighting the back wheel and shifting your weight over the front.
I guess it could be done with the front brake from here, but I find it easier to take in enough speed so that once the back end is unweighted, momentum carries me the rest of the way up.
There's my overly complicated explanation. :lol: Let me know if it's any use!
