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 check 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 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.
