User manual →Tuning control
You can activate tuning in the SpeedBox App (Tuning off / Tuning on).
You can also turn it on using the e-bike controller by pressing the LIGHT button.
The display will briefly show 9.9 km/h (6.2 mph), which means tuning is on — from this moment there is no speed limit and the speed depends only on the motor output and your pedaling cadence.
Deactivate tuning 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 a LIGHT button, you can control tuning with the + – + – button combination.
Custom speed limit settings
SpeedBox allows you to set a custom speed limit (for example, to save battery).
You can change the speed limit in the SpeedBox App.
Or on the controller, switch to Turbo mode and then shift 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 press of the LIGHT button (or by rotating the rear wheel 360°).
Example: 3.0 km/h = 30 km/h limit, 4.5 km/h = 45 km/h, etc.
The last selected limit is saved automatically after 5 seconds of inactivity.
Recommendations for riding and stopping
During a short stop, keep one foot on the pedal so the countdown doesn’t start.
During a longer stop, 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
- Rules for using derestricted e-bikes vary by country, so please check your local legislation before riding.
- SpeedBox is intended for off-road use only and you use it at your own risk.
- The manufacturer is not liable for damages 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.
