Video guide

You can find a detailed installation procedure on our YouTube channel

Printed manual

Inside the product package you will find a printed manual including a wiring diagram for connecting the chip to the motor

Tip: To identify the correct speed sensor connector — which is often well hidden inside the frame — gently pull on the sensor cable attached to the rear fork. By gently pulling, you will see which connector moves — this is how you'll find the right one to connect the SpeedBox.

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 a clear description.
