SpeedBox 1.2 B.Tuning for Shimano (E8000, E7000, E6100, E5000)

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.

SpeedBox B.Tuning chip can be used even without the SpeedBox App. However, it is a great accessory that will give you a complete overview of your performance. Most sport apps use only rough estimates of values. That’s why these data may differ from the real electric bike data by up to 20%. SpeedBox App displays completely accurate data, which is read directly from the electric bike's control unit.
