Coros Bike Speed Sensor

COROS Bike Speed Sensor is a lightweight and weather-resistant accessory that delivers precision speed and distance tracking—no GPS needed.

Key Features:

• Real-Time Speed & Distance Tracking
  Accurately measures your speed and distance by detecting wheel rotations, multiplying rotation rate by wheel circumference for reliable data. 

• GPS-Free Performance
  Ideal for both outdoor rides where GPS might be limited (e.g., dense urban areas or wooded trails) and indoor training sessions where GPS fails to function. 

• Bluetooth Connectivity
  Seamlessly pairs with bike computers, GPS watches, and training apps using Bluetooth. Often supports simultaneous pairing with up to two devices. 

• Easy Installation
  The sensor fits into a silicone case that straps around the front or rear wheel hub. Mounting is quick and intuitive—wake-up is achieved simply by spinning the wheel twice. 

• Long Battery Life
  Powered by a standard CR2032 button cell that lasts up to 12 months with daily use of one hour. Comes with an LED indicator that changes color to alert when replacement is needed. 

• Water-Resistant & Lightweight
  Built for durability, it features an IP67 rating for full protection against dust and water. Weighs only 17 grams, adding virtually no weight to your wheel. 

• Calibration for Accuracy
  For precise tracking, enter your wheel’s circumference during setup. You can adjust this later via your COROS device’s accessory settings.

COROS Bike Speed Sensor Track your speed and distance accurately—without relying on GPS. Lightweight, durable, and easy to install, this Bluetooth-enabled sensor delivers seamless performance for both indoor and outdoor rides.
