A smart product of the third generation with an option to set a speed limit for Specialized e-bikes with Specialized motors (including SL motors)

SpeedBox 3.0 tuning product disables the speed limiter on the e-bike and you can enjoy riding at unlimited speed. After the product is installed, your e-bike’s display will show real data, such as maximum and average speed, daily mileage and cruising range.

How does SpeedBox 3.0 for Specialized work?

SpeedBox is installed into the e-bike frame under the TCU/ TCD unit. You will activate the tuning by switching the e-bike off and on twice. After that, the tuning is still active with a set maximum assistance speed of 50 km/h.

You can set the maximum speed limit by switching the modes from TURBO mode three levels down and then three levels up (TRAIL - ECO - OFF - ECO - TRAIL - TURBO). The display will show the default maximum speed limit of 25 km/h. With each brief activation of the WALK function, you will increase the maximum speed limit by 5 km/h (some types of displays may round up the number to the nearest whole number). The last displayed limit will be saved after 5 seconds of inactivity. The set limit must be confirmed by turning the e-bike off and on twice.

You can check the currently set maximum speed limit by pressing the + - + - button combination.


When connecting the SpeedBox to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our tuning product is just as easy. If you need any help, feel free to contact us anytime.

If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 10 km before the product is activated.

Detailed installation information can be found here.

2) Turn off the e-bike again and uninstall the SpeedBox from the e-bike frame.

3) Update the software if you need.

4) Install the SpeedBox back into the e-bike and then switch the e-bike off and on twice. After that, the tuning will be still active.
