1. Insert a new battery into the bike speed sensor.
The COROS Bike Speed Sensor operates on a CR2032 button cell battery. To open the battery cover, twist the cover counterclockwise. After placing the new battery inside, twist the cover clockwise to secure it. The LED light on the front of the sensor will illuminate to indicate the sensor is awake.
2. Connect with the COROS app.
- You will need to download and create a COROS account to set up your bike speed sensor.
- Once you are logged in, open your COROS app to the Profile page (fourth tab on the bottom).
- Select "Add New Device".
- Scan the QR code that came with the instruction manual in the box.
- Wait for the pairing process to complete.
3. Mount the sensor on your bike.
- Insert the speed sensor into the silicone cover.
- Wrap the silicone case around either the front or rear wheel hub of your bike. Fasten the loop from one side of the silicone case around the hook on the other side to secure it in place.
- Once the sensor is mounted, you can wake it up again by rotating the wheel twice.
