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. If you want to uninstall the SpeedBox from your e-bike, first set the maximum assist speed to 25 km/h by switching the modes three levels down and then three levels up. Then confirm by turning the e-bike off and on twice. The speed indication in the Specialized Mission Control app is not functioning correctly. If you have a TCU without a display on your e-bike, or lacks a Walk button, we recommend purchasing the B.Tuning version compatible with the SpeedBox App.
