Inventing the worlds first transmission hub directly connected to crank,Direct Transhub Direct Bike was made possible by Bygens innovation in technology Bygens patented core technology

Transmission hub directly connected to cranks.

Bygen invented the worlds first Direct Transhub that runs using cranks only and without chains or other power transmission devices that replace chains that cause power loss. (Dirt on bicycle chains also causes power loss)

• Has more power than conventional bicycles because there is no power loss due to chain tension or dirt on bicycle chains.

• As a result, Bygen was able to develop and manufacture a variety of direct bicycles that possess power, portability and even beauty.

• In order to build a finished product bike, all parts except for brakes, not just Direct Transhub and Powercrank, including carbon frame, carbon wheel, folding handle and gear lever, must be developed and manufactured independently.

• Among all the bicycle producers in the world, there are only a few finished product manufacturers that independently develop and manufacture all the parts themselves as Bygen does.

•Bygen, using its independently developed carbon forming technology, is producing a variety of carbon products in its manufacturing factories .
