You can set the maximum speed limit in SpeedBox App or by switching the modes from TURBO: eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by activating WALK assist function shortly or by turning the rear wheel 360°. Every activating increases speed for 5 km/h. The last displayed limit will be saved after 15 seconds of inactivity.
After finishing the ride, leave the bike on until a value of 0.0 km/h is displayed. During this process the remaining time will be displayed. Then it is safe to turn off your bike and you can start looking forward to your next trip. Do not remove the display to lock the e-bike until SpeedBox finishes the "countdown" process. Installation video on our YouTube channel @SpeedBoxTuning
We recommend not to exceed a speed of 35 km/h. Do not update your e-bike's firmware – it increases the risk of tuning detection. Disable auto-updates in the eBike Flow App. Warranty void if motor issues are caused by firmware updates. When stopping briefly, keep one foot on the pedal to avoid triggering the countdown. For longer stops, allow at least a partial countdown to complete. After long rides, countdown may take several minutes.
Do not remove the display before the countdown finishes. Activate/deactivate tuning only when stationary, never during the ride.
