Tuning control

You can activate tuning 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).
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.
