Peugot has taken great liberties with the B1K Bicycle Concept, a carbon-constructed race bike built for the track and urban roadways.

This bike looks bad-ass, even if we struggle to comprehend how on earth the chain-less drive train works, those are details we’re willing to overlook, for the time being at least.
