User manual →Tuning control
Activate tuning by double-pressing the LIGHT button.
The display briefly shows 5 km/h (3 mph), which means tuning is active — from this moment there is no speed limit and your speed depends only on motor power and pedaling rhythm.
Deactivate tuning the same way.
The display shows 2 km/h (1 mph) and the bike returns to the original 25 km/h limit.
Alternatively, tuning can be controlled using the + – + – button sequence.
Custom speed limit setting
SpeedBox allows you to set your own speed limit (for example to save battery).
On the controller switch to AUTO mode and then move 3× down and 3× up in this order:
→ STD → ECO → OFF → ECO → STD → AUTO.
The display shows the current speed limit.
Double-press LIGHT to increase the limit by 5 km/h each time.
The last selected limit saves automatically after 5 seconds of inactivity.
Note: The display does not show decimal points.
For example, a displayed value of 3 km/h actually means 30 km/h, and after another double-press it becomes 35 km/h.
