That's pretty cool. No brakes, though.:eek: (Okay, I know that in order to accomplish that bendiness, the required amount of slack in the brake cables would render them totally useless, but still....)

that's what feet are for- you can Fred Flintstone the stop. ;)

Cool bike!

Can't blow up the picture, but gotta assume it's a fixie.

I don't know why it couldn't have brakes though. The rear brake cable housing on a "normal" bike is flexible, it's only the frame that keeps it from bending. You'd have to anchor the ends a little better than they usually are, is all (or conversely, make them slip a little more). As far as the front brake - nothing different there at all.
