Calibrate wheel circumference in your head unit or app if required to ensure accurate distance and speed calculations. Replace the coin cell battery when the device indicates low power to maintain continuous data transmission.

Recommendations

Place the sensor close to the hub or securely on a spoke to prevent movement during rides. Verify pairing and correct wheel circumference settings before starting a ride for best measurement accuracy. Periodically check mounting hardware and battery status to ensure uninterrupted performance.
