BADASSBOX for POLINI Motors

Where is your sensor?

The speed sensor and its positioning are decisive for which badass box you need.

We distinguish between the classic mounting on the chain stay and the integrated mounting in the area of the dropout.

Sensor on the chain stay

A good indication that your sensor is on the chain stay is the presence of a spoke magnet.
In addition, the sensor is usually direct and easily visible.

Polini Sensor

If this sensor of your Polini motor - as shown in the picture below - is located on the chain stay of your bike, then the badassBox 4 Polini is exactly what you need.
