Getting Started
- While the Bike Speed Sensor 2 is ready to use right out of the box, we do recommend checking and/or replacing the CR2032 battery installed during production before mounting to your bicycle.
- The sensor will now be ready to connect with your compatible GPSr.
- Garmin Bike Speed Sensors can be paired with multiple ANT+ devices.
- The Bike Speed Sensor 2 can pair with up to two Bluetooth devices.
Pair GPSr and Bike Speed Sensor
- Bring GPSr and Speed Sensor within 3m (10 ft) of each other.
- Ensure no additional wireless sensors are located within this 3m (10 ft) range.
- Rotate wheel with Bike Speed Sensor (without turning crankshaft) 2 full revolutions to wake the sensor (green LED flashes for 5 seconds) .
- If the LED flashes red, the battery charge level is low and requires replacement.
- If the LED does not flash, check battery installation for correct polarity and replace as needed.
- Select [Setup] > [Sensors] or [ANT Sensor] > [Bike Speed Sensor] > [Search For New].
- GPSr will report 'Searching...'.
- If a Bike Speed Sensor 2 is located, your
device may allow you to choose either an ANT+ or Bluetooth connection:
- ANT+ - Allows unlimited device connections.
- Bluetooth - Only a limited number of device connections are allowed (usually 2).
- The GPSr will report 'Connected' once the Bike Speed Sensor is paired.
- It may be helpful to continue rotating the wheel during this initial setup procedure.
Enable Bike Speed Sensor
- Select [Setup] > [Sensors] or [ANT Sensor] > [Bike Speed Sensor] > [On].
- GPSr will report 'Searching...' then 'Connected' once a Bike Speed Sensor is located.
- The GPSr may not display 'Connected' until the Bike Speed Sensor starts transmitting data.
Disable Bike Speed Sensor
- Select [Setup] > [Sensors] or [ANT Sensor] > [Bike Speed Sensor] > [Off].
- GPSr will report the Bike Speed Sensor as 'Disabled'.
View Bike Speed Sensor Data on GPSr
- Bike Speed data can be viewed on your GPSr in multiple Data Fields.
- Data Field availability may vary from one device to another.
