Eplus Speed Unlocker by Mountain Tuning for Bosch Gen2, Gen3 & Gen4
With the Eplus With Speed Unlocker, you can remove the 25 km/h speed limit on your Bosch e-bike, increasing the motor support to over 40 km/h. This allows you to finally utilize the drive's full power.
This tuning module's functionality is limited to the absolute essentials: removing the preset speed limit. After installation, the tuning is activated/deactivated via the WALK button on the e-bike. Incidentally, the e-bike display will display the real speed and the correct kilometers display, even with tuning activated (the battery range is almost correct).
Specifications
- Hardware: It is a buildable module with connectors.
- Preset control button: Walk (turns tuning on and off).
- Correct values on the display (Kiox, Purion, Intuvia, Nyon2).
- Kilometers traveled on the display: correct (kilometers traveled halved only for Nyon BUI275).
- APP-enabled: No.
Instructions
The Eplus Speed Unlocker is a module that must be connected to the engine (the necessary connectors are included). For installation, the engine cover must be temporarily removed and a pedal may need to be removed. After installation, the tuning is not visible from the outside. The module does not require its own battery. Further technical information can be found in the enclosed manual and in the Video Tutorial.

Tools
To install an E-Bike tuning chip in your E-Bike it is sometimes special tools necessary. Please check previously whether you have to open the engine compartment to access the motor connectors. This is especially true for products from the Modules, Kit, Dongle and Sensor.
Normally (but not always) opening the engine compartment requires loosening the crank. To do this, you will need a Crank puller. Some engines also have a Spider Tool This is important for opening the lock ring on the chainring - because the chainring must be loosened here so that the motor cover can be removed to access the inside of the motor. If you want to replace the chainring (wear, change the gear ratio), you often need a Spider Tool. The necessary special tools can also be found in our shop. To remove the engine cover, you usually need a Torx or Allen key. For installing the modules, appropriate Pliers from the electronics sector.
Do you decide not for a tuning solution that you have to install in the engine compartment (Box, Software), there is no need for any tools. In our Guide you will find further tips.

Important information on tuning measures for e-bikes and e-scooters
We expressly point out that any modification to e-bikes and e-scooters – whether through hardware tuning (e.g. tuning chips, dongles, sensor adapters) or software tuning (e.g. apps, programs or USB tools) – can have consequences.
Tuning measures on e-bikes and e-scooters mean that they are no longer permitted for use on public roads as defined by the StVZO (Road Traffic Licensing Regulations). Legal use is therefore only possible on private property or - if permitted - in competitions. Riding an e-bike or e-scooter modified by tuning measures on public roads can lead to criminal liability for driving without a license (Section 21 of the Road Traffic Act) and driving without insurance (Section 6 of the PflVG). Tuning measures on e-bikes can lead to the loss of warranty rights and manufacturer guarantees. Furthermore, tuning measures can lead to the loss of insurance coverage and benefits from accident victim assistance in the event of an accident. The e-bike (or e-scooter) modified by tuning measures is subject to additional stress due to the higher speed, which can lead to safety risks.
