3.2. Sensor Mounting (Speed or Cadence)
The sensor can be configured as either a speed sensor or a cadence sensor. The installation method varies based on its intended function.
For Cadence Tracking:
Attach the sensor to the inner side of your bike's left crank arm using the provided rubber bands or cable ties. Ensure it is securely fastened and does not interfere with pedaling.
For Speed Tracking:
Attach the sensor to the rear wheel hub. Ensure the sensor is aligned with the wheel magnet, which should be installed on a spoke opposite the valve. The gap between the sensor and the magnet should be less than 12mm.
