S3+ ANT+ and Bluetooth Speed or Cadence Sensor

Add speed or cadence data to a compatible cycling setup with an S3+ sensor that supports both ANT+ and Bluetooth.

✅ Choose the measurement role - The same sensor can be configured for either speed or cadence use.

✅ Connect to supported training equipment - ANT+ and Bluetooth provide connection choices for compatible computers and apps.

✅ Install without a separate magnet - The sensor's internal motion-sensing arrangement does not require an external wheel magnet.

Choose speed, cadence or a pair

Speed and cadence describe different parts of a ride. Configure one sensor for the reading you need, or use the two-sensor package when you want a separate sensor for each role.

Check support on the exact bike computer or app before pairing. The mode-switch procedure involves the battery arrangement as instructed, and the mounting position must match whether the unit is measuring wheel speed or pedalling cadence.
