Garmin Bicycle Speed Sensor (2)

The Garmin Bicycle Speed Sensor (2) is a compact, wireless sensor that accurately measures your cycling speed. It uses both ANT+ and Bluetooth Smart technology to transmit data to compatible devices such as Garmin Edge cycling computers, fitness watches, and smartphone apps. The sensor is easy to install on the rear wheel hub and requires no magnets or calibration.

With a battery life of up to 12 months from a single CR2032 coin cell, the sensor is designed for long-term use. Its IPX7 water rating ensures it can withstand rain and splashes, making it suitable for all-weather riding. The sensor is lightweight at just 11.6 grams and has a low-profile design that does not interfere with the bike's aesthetics.
