The design of a special HSG gearbox with 16:1 ratio was developed for the company DG TWIN.

The gearbox is designed to be mounted on conventional mountain bikes not equipped with electric propulsion.

The power of the electric motor is 120 W with a DC supply voltage of 24 or 48 V.

The gearbox has been designed by applying the HSG (Long-Addendum) theory by taking advantage of a high reduction ratio of 16:1, in a single stage.
