I was messing around with something tonight, and I'm quite sure someone has done it before...
It's like an un-steamroller. (can be extrapolated to an un-whiplash, or un-whopper, or whatever your imagination holds)
Basically, you hold your hands all funny on the grip and seat, then snap the bike in front of you so that you're in the steamroller position (or further...), but the front end never changes angle on the head tube. Does that make sense?
I am quite sure someone's done this before, because this is small potatoes compared to all the sh*t people have come up with. Show me though?
