Compatible with PSB and other sensor magnets.
One of the most common signal generating mechanism, PSB's sensor magnet rotor series allows you to enjoy the full functionality of your e-bikes.
First, install the magnet housing through the hole from the back of the rotor. Then slide the o-ring from the front down onto the rotor surface, and place the spring washer.
Please note that there must be a 4mm minimum clearance between the magnet and the speed sensor or the bicycle frame. If the gap is less than 4 mm, the magnet must be installed in the reverse direction, ensuring sufficient clearance between the components.
Pressing down on the washer with an 8mm socket wrench will help secure the sensor magnet.
