I flipped my bike not too long ago. Clipped in moving wheelie, held it for a couple of pedal revolutions, then went too far back. Tried to yank my feet back like on the bmx if aborting a manual and just kicked the whole bike out from under me. It tweaked my wheel, fender and scuffed the brooks. Now I remember why I also have a bike with a 48H rear wheel and platform pedals.
