SpeedBox 1.3 B.Tuning for Shimano (EP8)

From the ground up redesigned tuning chip for your e-bike with a Shimano motor – with a new design, completely new hardware and firmware, and Bluetooth technology to connect your e-bike with a mobile app.

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.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

The SpeedBox 1.3 tuning chip enables you to suppress the speed limiter on your electric bike. This unlocks the power of the Shimano motor, allowing you to achieve unlimited speed. When in use, the actual speed will appear on your display up to 14 mph (23 km/h).

The manufacturer recommends keeping the maximum speed for Giant models up to 21-22 mph (35 km/h).

To see the correct speed and all riding data during your ride, refer to the SpeedBox App on your smartphone.



This tuning chip is 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 preferable maximum speed limit in the app.

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. It is highly recommended to open the motor and refer to product pictures if you are uncertain about the situation under the cover.



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 kit does not support Shimano EP801 and EP6 motors. For Shimano EP801 and EP6 motors you would need Peartune for Shimano EP801 and EP6

For the Shimano E8000, E7000, E6100, E5000 motors, you would need Speedbox Shimano 1.2 tuning kit.

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 0.6 miles (1 km) before the chip is activated.
