Skip the chest strap. The COOSPO HW9 reads your heart rate from your arm and shows your training zone on a five-colour LED, so you can check your effort at a glance and adjust as you ride.

Highlights

  • Five-colour LED shows which heart rate zone you're in
  • Bluetooth 5.0 and ANT+, with two Bluetooth connections at once
  • HRV support
  • IP67 rated (not suitable for swimming)
  • Up to 35 hours per charge, with magnetic USB charging
  • 20 g including the elastic nylon armband

Connect it your way

Pair the HW9 with GPS watches, bike computers, fitness equipment and apps. COOSPO says it works with third-party apps such as Strava and Wahoo over Bluetooth, and you can set its vibration and LED functions in the CoospoRide app. If you wear a smartwatch, turn off the watch's own heart rate function while using the HW9. COOSPO quotes ±1 bpm real-time tracking from its third-generation optical sensor algorithm.
