It detects speed and transmits data to a compatible device during the ride. The system uses a dual-meter algorithm and allows you to monitor speed even without GPS signal.\u003c\/p\u003e\n\u003ch3\u003eABS body and CR2032 power supply\u003c\/h3\u003e\n\u003cp\u003eThe sensor features an \u003cstrong\u003eABS\u003c\/strong\u003e body measuring 34.05 × 31.80 × 8.50 mm and weighing 8.4 g. The construction is waterproof. Power is provided by a \u003cstrong\u003e220 mAh CR2032 battery\u003c\/strong\u003e, with a declared battery life of 300 hours. Magnet-free detection does not require placing a separate magnet on the wheel.\u003c\/p\u003e\n\u003ch3\u003eConnection to bike computers, smartwatches, and apps\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eBluetooth 5.0 and ANT+\u003c\/strong\u003e connections allow the BK9S to be paired with compatible bike computers, smartwatches, and fitness apps. When choosing the receiving device, it is necessary to verify support for speed sensors via one of the two protocols. The intended mounting position is on the hub, unlike cadence sensors mounted on the crank arm.\u003c\/p\u003e\n\u003ch3\u003eTechnical features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: Coospo BK9S.\u003c\/li\u003e\n\u003cli\u003eFunction: speed detection.\u003c\/li\u003e\n\u003cli\u003eDetection system: magnet-free, with dual-meter algorithm.\u003c\/li\u003e\n\u003cli\u003eMounting position: wheel hub.\u003c\/li\u003e\n\u003cli\u003eWireless connections: Bluetooth 5.0 and ANT+.\u003c\/li\u003e\n\u003cli\u003eBody material: ABS.\u003c\/li\u003e\n\u003cli\u003eDimensions: 34.05 × 31.80 × 8.50 mm.\u003c\/li\u003e\n\u003cli\u003eWeight: 8.4 g.\u003c\/li\u003e\n\u003cli\u003eBattery: 220 mAh CR2032.\u003c\/li\u003e\n\u003cli\u003eDeclared battery life: 300 hours.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003ch4\u003eWhere is the Coospo BK9S mounted?\u003c\/h4\u003e\n\u003cp\u003eThe sensor is designed to be installed on the bicycle wheel hub.\u003c\/p\u003e\n\u003ch4\u003eIs a separate magnet needed to detect speed?\u003c\/h4\u003e\n\u003cp\u003eNo, the BK9S uses a magnet-free detection system and can monitor speed even without GPS signal.\u003c\/p\u003e\n\u003ch4\u003eCan it be connected to a bike computer or smartwatch?\u003c\/h4\u003e\n\u003cp\u003eYes, via Bluetooth 5.0 or ANT+, provided the receiving device supports speed sensors through the protocol used.
