SpeedBox 3.1 for Specialized Levo, Kenevo, Levo SL, Kenevo SL, Creo SL, Vado SL

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]

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.

Note: Speed indication in the Specialized Mission Control app may not display correctly. If you have a TCU without a display or without a Walk function, we recommend purchasing the B.Tuning version compatible with the SpeedBox App.
