While most bikes have the tried and true chain system to propeller them forward, a collection of hungarian inventor have created a new method from pedaling using cables.

The stringbike, as they call it, looks pretty much like a normal bike, until you get up close to inspect it. Instead of the standard chain, the bike has a series of cables on each pedal that spin the rear wheel hub forward. these cables then spin freely on the pedals back swing, allowing the wheel to continue spinning despite not being spun further.
