Once installed it doubles the cut off speed. It can also be used with the Bosch S pedelec motors as it works in the same way. The dongle can be easily unplugged whenever necessary to revert the bike back to normal.

The display will read the wrong mph, when the dongle is operating the speed and anything related to speed is halved, so it should be doubled for a true reading. It's simple, if it says you are going 5mph then you are actually going 10mph. As soon as it's unplugged the speed readout will revert back to normal.

Please Note: We use the reference to Bosch in the sense that this will fit Bosch powered eBikes. This product is not manufactured, produced or endorsed by Bosch themselves.

This can be added at time of purchase but please note that if workshop time is requested to fit further down the line we will be happy to assist however a small labour charge will be added.

By going over the 15mph cut off these dongles are FOR OFF ROAD (PRIVATE LAND) USE ONLY! They may not be used on the road, cycle paths, bridleways or anywhere else where the public have access.

Tuning devices are supplied on the basis that they may only work with the software version of the bike supplied at the time of supply & no warranty or guarantee is given that these will continue to work with future software versions or upgrades.
