Purists will argue that a bunny hop is different to a pedal lift. I can't bunny hop, which is actually a manual, followed immediately by a scoop of the pedals. Clipped in however I can somewhat brutally wrench the front end into the air, then lean forward and lift the back up over an obstacle.............Clipped in or on platform pedals? I've been told that one of the advantages of clipping in is being able to lift the back wheel.
Going uphill for me as well, i can do it but i am a better descender, this might change when i get a lighter bike i certainly know i am dragging it up hill atm.
