Monitor your speed as you ride with this easy-to-install wireless sensor. With no magnets or other exposed parts to line up, this sensor is easy to install, maintain and move between bikes.
The Speed Sensor 2 attaches to the hub of either wheel. You can set up wheel size in our Garmin Connect™ online community or self-calibrate with an Edge® cycling computer or compatible Garmin device. Once set up, you'll get accurate speed and distance at all times — even without a head unit.
ANT+® connectivity and Bluetooth® Low Energy technology let you sync to Garmin Connect and other training apps, compatible devices and fitness equipment for better data when you ride indoors and outdoors. The odometer feature tracks your distance to help plan for bicycle maintenance.
Replacing the Speed Sensor Battery
The device uses one CR2032 battery. The LED flashes red to indicate a low battery level after two revolutions.
- Locate the circular battery cover on the front of the sensor.
- Twist the cover counter-clockwise until the cover is loose enough to remove.
- Remove the cover and the battery .
- Wait 30 seconds.
- Insert the new battery into the cover, observing polarity. NOTE: Do not damage or lose the O-ring gasket.
- Twist the cover clockwise so that the marker on the cover aligns with the marker on the case. NOTE: The LED flashes red and green for a few seconds after battery replacement. When the LED flashes green and then stops flashing, the device is active and ready to send data
