New bike design uses wires and discs instead of a chain

Bike chains are messy and can break. But bike wires? Why, they're the wave of the future! At least according to the designers from the Schwinn Csepel Zrt.
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.
It seems like a pretty interesting system, one that may make its way to mass-market bikes at some point in the not-too-distant future.
