Chopped handle bars?

yeah, but your hips are similar height to your bars. although if you get out of the saddle you can get your hips above wing-mirror height. but it's prolly not entirely sensible to be riding a fixed gear out of the saddle through a gap in traffic so tight you can't fit through without contorting yourself. you know, stability and all that.

occasionally you might want to though.

My favourite way to ride. Seriously it's all about contorting and tight gaps..<3
