Hungarian-based StringDrive claims that the current design of bicycles that have the drive chain and gears located on one side ends up as an asymmetric riding experience which could be more efficient or smoother if some changes were made to the design. This has resulted in the StringBike that relies on a couple of identical but opposing drive units on either side of the bike, featuring swinging arms that move forward and back as the pedals are turned. This unique motion will in turn pull a set of steel ropes on either side, causing a drum and the rear wheel to rotate. As the mechanisms on both sides are moving in symmetry with each round of the pedal, the rear wheel remains constantly driven to deliver a smoother and more efficient ride. Will this help pick up the interest in biking among the general public? We doubt so, but if it works as claimed, you might see more StringBikes around sooner rather than later.
