The Cycplus H1 is an optical heart rate monitor that you wear comfortably around your arm. The sensor measures your heart rate and converts it into digital data, allowing you to train directly based on your heart rate during exercise. For proper functioning, the strap should fit snugly against the skin. Thanks to ANT+ and Bluetooth (BLE), you can easily pair the H1 with compatible bike computers, sports watches, and training apps. The LED indicator provides real-time feedback on your heart rate (green <80 bpm, orange 80-140 bpm, red =140 bpm). Charging is done via magnetic charging and takes approximately 30 minutes. The battery lasts up to approximately 110 hours (depending on usage) and with IPX6, the H1 is ready for use in various conditions.
