Garmin Bike Cadence Sensor 2, Black

The Garmin Bike Cadence Sensor 2 is a wireless accessory designed for tracking pedalling cadence on a bicycle. It attaches directly to the crank arm and monitors pedalling rhythm during rides. The design removes the need for external wheel magnets or exposed alignment components. Installation is straightforward, and the compact unit fits crank arms of various sizes. Riders use the data to plan training sessions, monitor efficiency, and assess cycling performance over time.

The device uses an internal accelerometer to detect movement and calculate pedalling speed in revolutions per minute. Data is transmitted wirelessly to external receivers for real-time monitoring and post-ride analysis. This connectivity allows simultaneous pairing with multiple external devices without cables. Supported training applications can also receive the signal for a fuller evaluation of cycling metrics. The black housing stays firmly attached to the crank and can be moved between bicycles when needed.
