Garmin Bike Speed Sensor
Monitor your speed as you ride with these easy-to-install wireless sensors.
Simply attach the sensors and ride. With no magnets or other exposed parts to line up, these sensors are easy to install, maintain and move between bikes.
The speed sensor attaches to the hub of either wheel and self-calibrates with your Edge® to give you accurate speed and distance at all times, including indoors on the turbo trainer.
Combine both the Speed and Cadence sensors and improve your personal best or see where your stand against the pros.
