How do I adjust the brake sensor when it's not activating the brake light or cruise mode?

Since the shape of brake levers varies between different bicycle models, there is no fixed distance for installing the brake sensor. You can first attach one end of the sensor to the brake lever, then hold the small magnet in your hand and repeatedly adjust its position. By observing the white light on the red middle button of the Remote Controller or the brake light at the rear of the PikaBoost, you can find the position that works best for your brake lever, and then attach the magnet there.

Please note that before attaching, make sure to clean the surface of the brake lever to avoid poor adhesion.
