Derek's logic assumes that bike acts as a catapult to 'launch' the rider as it pivots on the front wheel, but that would mean the bike is now going faster than the rider (to apply an accelerative force) being launched off of it, which is impossible.

Yeah, I was like "where is that force coming from?" but now it seems like it's coming from nowhere
