TRP E-Bike Speed Sensors

This depends entirely on your current rotor mounting system. Check your wheel hub or the rotor itself; if it uses six bolts around the center, you need the 6-bolt version. If it uses a splined interface with a lockring, you need the Centre Lock version.

These sensors are designed for compatibility with specific TRP and compatible e-bike drivetrains. Because e-bike speed sensing can be proprietary, always verify your specific motor system's requirements before purchasing to ensure the magnet and sensor will communicate correctly.

If you are comfortable removing and reinstalling your brake rotors, you can install these sensors yourself. However, it requires basic mechanical knowledge and the correct tools for your specific rotor type, so consult your bike's service manual if you are unsure.

The magnet must be positioned precisely to trigger the sensor on your frame or fork. Using the correct mounting type ensures the magnet sits at the exact distance and alignment required for the sensor to pick up accurate speed data without interference.

This product is specifically the speed sensor magnet component. It is designed to work in conjunction with your existing e-bike speed sensor system to provide the necessary signal for speed tracking.
