According to Iván Paróczai, marketing manager of Schwinn-Csepel, the new concept has already drawn a lot of attention, but standardized production is yet a further step.

Gábor Rácz, the inventor of the chainless bike, presented the new concept to his students at the Budapest University of Technology and Economics already during the beginning of the 90s. He intended to apply the same durable mechanism found in computer hard-drives.

On the Stringbike, the crankarm, instead of turning a chain around the chainring, moves two trailing arms via a bearing, which pull two durable plastic strings that are connected to the rear
hubs of the wheels through two wheel drums. The strings either coil up around the drums or roll off them if the strings are let go or are pulled by the trailing arms, respectively.

According to the designers, the new concept lets the biker switch between gears while standing still, the strings are even more durable compared to regular chains, and the disassembly of the vehicle becomes faster, thus making transportation easier.
