E-bike tuning bikespeed-RS for Bosch

Tax included. Shipping calculated at checkout.

The bikespeed RealSpeed ​​tuning removes the speed limit of 25 km/h for all pedelecs with a Bosch mid-motor. 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 with all e-bikes currently on the market with a Bosch central motor (year of construction 2011 to 2022). The engine type (Classic, Active-Line, Active Plus-Line, Performance-Line and CX-Line, Display (HMI, Intuvia, Nyon, Purion and Kiox), the software version (*), the tire size, etc. doesn't matter.

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

The installation is completely invisible within the stone chip protection cover of the engine of your ebike. The tuning can be switched on and off with a key combination on your Bosch 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 for all pedelecs with a Bosch mid-engine and you do not have to make any settings.

Due to the principle, the well-known error 102 or 503 is finally a thing of the past with this tuning. A gear conversion is not necessary.

The scope of delivery consists of the bikespeed-RS tuning and illustrated installation instructions. Additional fastening material is not required. You may need a commercially available crank puller and a Torx T20 screwdriver for installation. For all Bosch motors built up to 2013, as well as the Bosch 2014 Classic+, you still need a tool to open the chain ring nut (spider tool). You can buy this in our other offers.

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
