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 B.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. Thanks to SpeedBox App mobile application you can monitor and store all the parameters of your trip on the display of your phone in any place, anytime.

How does SpeedBox 3.0 B.Tuning 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 of your own choice in the App or 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 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 in the App or by pressing the + - + - button combination.
