Tuning control

You can turn the tuning on by activating the WALK function.
The display will briefly show the value 9.9 km/h (6.2 mph), which means tuning is enabled — from this moment there is no speed limit and the speed depends only on the motor output and your pedaling cadence.
Deactivate the tuning the same way.
The display will show 2.5 km/h (1.6 mph) and the e-bike returns to the original 25 km/h limit.
If you don’t have a controller with the WALK function, you can control the tuning using the button combination + – + –.

Setting a custom speed limit

SpeedBox allows you to set a custom speed limit (for example, to save battery).
On the controller, go to Turbo mode and then switch 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 by 360°).
Example: 3.0 km/h shown = 30 km/h limit, 4.5 km/h = 45 km/h, etc.
The last selected limit is saved automatically after 5 seconds of inactivity.

Riding and stopping recommendations

For a short stop, keep one foot on the pedal so the countdown doesn’t start.
For a longer stop, let the countdown run at least partially.
After a long ride, the countdown may take several minutes – do not disconnect the display until the process is finished.

Warning

The use of derestricted e-bikes varies by country, so please check local legislation before riding.
SpeedBox is intended for off-road use only and is used at your own risk.
The manufacturer is not liable for any damage caused by illegal or improper use.
Installation may also result in the loss of your e-bike warranty.
For your safety, use appropriate protective equipment and ride with maximum caution.
