SpeedBox Tuning for Shimano EP8 + E-Tube Port

The tuning chip SpeedBox 1.3 enables you to suppress the speed limiter on your electric bike. When in use, the actual speed will appear on your display up to 23 km/h.

SpeedBox 1.3 B.Tuning offers a unique connection between your e-bike and mobile phone. This tuning chip is a top-notch product perfectly optimized for the most powerful ride and experience. It suppresses the speed limiter so you can enjoy your ride at unlimited speed. After pairing with the SpeedBox App mobile application, you will see real riding data on your phone’s display. You may also set the speed limit of your own choice. Monitor and store all the parameters of your trip on the display of your phone in any place, anytime.

Compared to previous versions, this new product also plugs into the engine's E-Tube port. It is therefore necessary that the e-bike motor in which you are going to install the new version of SpeedBox for Shimano has one free E-Tube port. In case you do not have a free E-Tube port in the motor, please select “+E-Tube Port” variant.

E-bikes, which do not have a free E-Tube port, are usually those with a Di2 electronic gear shifting system, or with a tube integrated Satellite System ON/OFF Switch (EW-SW100, EW-SW300).

This tuning chip is also very easy to control - via mobile app or by turning on/off the lights. If the lights are turned off, SpeedBox is activated. The chip can be easily deactivated by turning on the lights. A new feature in this SpeedBox version is the possibility of activating the double-click function in the app. By activating this function, the lights become independent of tuning. By double-clicking on the LIGHT button, the lights will flash, and the tuning will turn on. If you double-click on the button again, the tuning will turn off and the e-bike will work the same as without a chip. 

You can set the maximum speed limit in the app.

We use original connectors for the production of SpeedBox chips ensuring that the installation process is very simple and the chip is connected properly. We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the tuning chip is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.

If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 1 km before the chip is activated.
