The COROS Bike Speed and Cadence Sensors pair to bike computers, GPS watches, and other devices via Bluetooth. ANT+ connections are not supported. The sensors can pair with up to two other devices simultaneously.
How to Pair
Wake up the COROS bike sensor by spinning your wheel or crank arm. The light on the front of the sensor will illuminate to indicate that it's in pairing mode. If you haven't yet mounted the sensor on your bike, you can also remove the battery and replace the battery to wake it up.
With COROS DURA or COROS watches: Go to the System > Accessories > Add Bluetooth page on the device to search for and pair with the sensors.
Other devices: To pair with third party bike computers, indoor trainers, apps, and other devices, please refer to your device's user manual to search for and pair with the speed and cadence sensors.
Sensor won't turn on or pair
If the light on the front of the sensor doesn't turn on even after rotating your bike wheel/crank arm, try replacing the battery with a new one. The cadence and speed sensors both use a CR2032 button cell battery.
Ensure the battery is inserted correctly by following the steps here:
Tips for pairing the COROS Bike Speed Sensor
When pairing the speed sensor, make sure to select your wheel circumference. When pairing the bike speed sensor to a device for the first time, the device will prompt you to enter the wheel circumference of your bike to get the most accurate speed and distance measurements.
On your COROS DURA or COROS watch, you can adjust the wheel circumference at any time by going to System > Accessories > select the COROS Bike Speed Sensor > Wheel Circumference.
