User manual →Tuning control
You can activate tuning in the SpeedBox App (Tuning off / Tuning on).
Or you can turn it on using your e-bike controller by activating the WALK function.
The display will briefly show 3.5 km/h (2.2 mph), which means tuning is on — from that moment, no speed limit applies and your speed depends only on the motor output and your pedaling cadence.
Tuning is deactivated the same way.
The display will show 2.5 km/h (1.6 mph) and the e-bike will return to the original 25 km/h limit.
If your controller does not have the WALK function, you can control tuning using the + – + – button combination.
Custom speed limit setting
SpeedBox allows you to set a custom speed limit (for example, to save battery).
You can change the speed limit again in the SpeedBox App.
Or, on the controller, switch to Turbo mode and then toggle 3× down and 3× up in the following order:
→ EMTB → Tour → Eco → Tour → EMTB → Turbo.
The display will show the current limit.
Increase it by 5 km/h with a short activation of the WALK function (or by rotating the rear wheel 360°).
Example: display shows 3.0 km/h = 30 km/h limit, 4.5 km/h = 45 km/h limit, etc.
The last selected limit is automatically saved after 5 seconds of inactivity.
Recommendations for riding and stopping
When stopping briefly, keep one foot on the pedal so the countdown does not start.
When stopping for longer, let the countdown run at least partially.
After a longer ride, the countdown may take several minutes — do not disconnect the display until the process is finished.
Warning
- Laws regarding the use of derestricted e-bikes vary by country, so please check local regulations before riding.
- SpeedBox is intended for off-road use only and you use it at your own risk.
- The manufacturer is not liable for damage caused by illegal or improper use.
- Installation may also void your e-bike warranty.
- For your safety, use appropriate protective gear and ride with maximum caution.
