Step by step
The illustrated guide will walk you through the installation step by step — from removing the motor cover to the test ride. Each step is accompanied by photos and clear explanations.
Tuning control
You install the SpeedBox into the e-bike frame under the control unit. You activate the tuning by pressing the WALK button or using the - + - + button combination. The value 35.1 km/h will briefly appear on the display, indicating the preset maximum speed of 35 km/h. You deactivate the tuning the same way — the display will show 25 km/h and the e-bike will work the same as before the tuning was installed.
Setting a custom speed limit
You can change the maximum assistance speed by switching the modes from TRAIL three levels down and then three levels up: AUTO → ECO → OFF → ECO → AUTO → TRAIL. The current maximum assistance speed will then appear on the display. Each time you press the WALK button or rotate the rear wheel, the maximum assistance speed increases by 5 km/h. The last displayed limit is saved after five seconds of inactivity.
