E-bike tuning bikespeed-RS for Sachs

Tax included. Shipping calculated at checkout.
The bikespeed RealSpeed ​​tuning lifts the speed limit of a pedelec with a Sachs RS mid-motor at 25 km/h. Unlike the usual tunings on the market, the speed actually driven is displayed on the speedometer. All kilometer, average and maximum speed displays, range calculations, etc. also remain usable. Of course, the existing support levels and start-up profiles are retained.

The tuning works on all e-bikes with a Sachs central motor from 2020 to 2022, as well as the EOX Remote 500, EOX View 1200, EOX View 1300 or Bloks/BMZ 14D display.

If you have a Bosch, Yamaha, Brose, TQ or Panasonic mid-engine, please see our other auctions.

The installation is completely invisible inside the protective cover of the motor of your ebike. The tuning can be switched on and off with a key combination on your display or on the controls on the handlebars. When you switch on your bike and after entering the combination, the tuning informs you about its status with the help of a small animation. If the bikespeed-RS is activated, the tuning removes the limitation of the top speed, which means that it is only limited by the engine power and your own muscle power.

We have made the installation of the bikespeed-RS on your ebike as easy as possible. All necessary connections can be plugged into the proven bikespeed cable sets and can therefore be retrofitted without a trace. The tuning automatically adjusts itself to your pedelec when it is switched on. All necessary parameters such as engine, display, tire size, etc. are automatically recognized. The tuning can therefore be used immediately and universally and you do not have to make any settings.

The scope of delivery consists of the bikespeed-RS tuning including all required cables and illustrated installation instructions. Additional fastening material is not required. You need a standard Allen and Torx set for installation.

We expressly point out that operating the bikespeed-RS on public roads is not permitted. Already the presence of the tuning can constitute an offense of the StVo. We recommend using a converted bike only on private property. Operation on public roads is expressly prohibited by the StVo! You can find more information on this at
