Chest belt heart rate monitor Cycplus H2 — wireless chest strap for heart rate monitoring

Cycplus H2 is a wireless chest belt heart rate monitor designed to measure and transmit real-time heart rate data during training and daily activities. The device uses an ECG algorithm and supports both Bluetooth 5.0 and ANT+ connectivity to pair with compatible sports watches, bike computers and fitness apps. Lightweight and slim, the sensor attaches to an adjustable soft strap that conforms to the chest and resists sweat and rain with IPX7 protection.

Advantages

The ECG-based algorithm reduces interference from movement, breathing and muscle tension to deliver stable, accurate real-time heart rate readings and enable instantaneous detection of R-wave peaks. Dual-protocol wireless connectivity ensures broad compatibility with popular platforms and devices. A replaceable CR2032 battery provides long runtime of up to about 500 hours, and the sensor automatically enters sleep or wake modes to conserve power. The strap incorporates non-slip silicone points and an adjustable length to keep the sensor in constant contact with the skin while remaining comfortable for extended use.

Suitable for

• Cycling and mountain biking with external bike computers
• Running, jogging and interval training
• Gym workouts, strength and cardio sessions
• Indoor training apps and virtual platforms (e.g., Zwift, Strava)
• Daily heart rate monitoring and HRV analysis with compatible mobile apps

Key specifications

• Algorithm: ECG-based detection for accurate instantaneous heart rate
• Connectivity: Bluetooth 5.0 and ANT+ for wide device compatibility
• Power: Replaceable CR2032 battery, up to about 500 hours of operation
• Protection: IPX7 sweat- and rain-resistant housing
• Weight and size: Sensor thickness approx. 9 mm; sensor weight approx. 21 g
• Belt: Soft adjustable strap with non-slip silicone points, fit range 65–95 cm

How to use

Fasten the adjustable strap around the chest so that the sensor rests directly against the skin just below the sternum; wet the electrode areas slightly if needed to improve contact. Pair the Cycplus H2 with a compatible device or app using Bluetooth 5.0 or ANT+ according to the receiving device’s pairing instructions. The sensor powers on automatically when movement is detected and enters sleep mode when removed from the chest to save battery. Replace the CR2032 battery following the manufacturer’s guidance when runtime decreases.

Usage recommendations

For consistent measurements, position the strap snugly and clean both skin and electrodes after heavy sweating. Use the H2 with supported fitness platforms and save recorded sessions to analyze heart rate trends and HRV data. Store the strap dry and remove the sensor when not in use for long periods to extend battery life.
