COROS Bike Speed Sensor vs Garmin Forerunner 165
Side-by-side on the specs that matter, with category winners and an opinionated take to help you decide.
This choice is between a dedicated cycling sensor for accuracy and a versatile smartwatch that tracks everything but cycling data less precisely.
Pick the COROS Bike Speed Sensor if you travel with your bike and want reliable, automatic speed data without draining your watch battery.
Pick the Garmin Forerunner 165 if you travel for general fitness and want a single device to track runs, sleep, and daily activity.
- —The COROS sensor gives precise cycling metrics but requires a bike and a separate device, like a phone or watch, to view data.
- —The Forerunner 165 provides all-day health tracking and GPS but estimates cycling speed less accurately than a dedicated sensor.
- —Traveling with the Garmin is simpler as it's one wearable, while the COROS is an extra small item to pack and potentially lose.
