Korean bike manufacturer Bygen has devised a solution to a common problem posed by folding bicycles -- they can't be folded sideways along the frame, and transfer grease and gunk to riders' clothing when they carry their bike. To get around this problem, Bygen's Hank Direct Bike doesn't have a chain or belt drive, but is instead fitted with levers that transfer power from the pedals to the rear wheels.
Bygen designed the levers to join the hub via an articulated linkage. This allows them to be extended forward, placing the pedals in their regular position underneath the saddle.
The bike itself has three gear ratios thanks to its hub transmission. The absence of a chain means variations in tension are not a problem, resulting in up to an 8% increase in pedaling power.
