Step by step
The illustrated guide walks you through installation step by step — from removing the motor cover to the test ride. Each step includes photos and a clear description.
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.
