As you can see from the above photo, this new bike design features two cables rather than a bike chain. The pedal assembly consists of kidney-shaped eccentric discs, a swinging unit and the transmission. Those discs work like gears do on a traditional bike, and they can be swapped out for different-sized discs depending on what sort of riding you'll be doing.
