Warning:

Please note that using modified e-bikes of this type on public roads may be illegal. The manufacturer and retailer accept no liability for any damage resulting from the use of SpeedBox products. E-bikes equipped with SpeedBox products must not be used on public roads, cycle paths, or in public areas. E-bikes equipped with SpeedBox products may only be used on private property and entirely at your own risk. The use of SpeedBox may void your bike’s warranty. We strongly recommend using other safety features and protective gear to prevent injuries.

We do not recommend updating your bike’s software, as updates may affect the operation of the box.

Please note that opened electronic components (including SpeedBox, Speedfun, and Peartune products) are not eligible for the 14-day return or exchange policy. Non-functioning SpeedBox, Speedfun, and Peartune products covered by warranty are always sent to the manufacturer for repair. Read the warranty terms here.

How does the SpeedBox 3.1 for Specialized work?

The SpeedBox is installed on the e-bike frame under the TCU/TCD unit. Tuning is activated by turning the e-bike off and on twice. After activation, the tuning is active, and the motor will assist up to a speed of 50 km/h.

Speed programming.

You can adjust the maximum assistance speed as follows:

  1. Switch down three levels from Turbo mode and then three levels up (Trail → Eco → Off → Eco → Trail → Turbo).
  2. The default speed limiter of 25 km/h will appear on the display.
  3. Briefly activating the WALK function lets you increase the speed limiter by 5 km/h at a time (in some displays, the speed rounds to the nearest whole number).
  4. The last visible limit is automatically saved after 5 seconds of inactivity.
  5. To confirm the setting, turn the e-bike off and on twice.

You can check the current speed limit by pressing the button combination + - + -.

Note: The speed display in the Specialized Mission Control app does not work correctly with tuning. If your e-bike has a TCU without a display, we recommend the B.Tuning version, which is compatible with the SpeedBox app.

Installation

Connecting the SpeedBox to the e-bike is easy thanks to the color-coded connectors. We have prepared detailed installation instructions and videos to make the installation process smooth. Removing the tuning is equally simple. If you need assistance, our customer service is always available.

Note before installation:

If you are installing the SpeedBox on a new bike, make sure you have ridden at least 10 km before activating the tuning.
