The ratio on the belt/chain drive (secondary transmission) can easily be adapted to your requirements. A ratio calculator is available for selecting the correct transmission ratio under the following link.

With the Pinion gearbox, there are no limits to the secondary gear ratio, which means that the gear ratio can be reduced to fast and slow.

With belt drive please make sure that the front, rear pulley, belt and adjustment range of the bicycle frame fit together.

Further information can be found here on the respective manufacturer's homepages or ask your dealer.
