COOSPO BK9 Speed & Cadence Sensor Set – Magnet-Free, Bluetooth 5.0 & ANT+, IP67, 300-Hour Battery for Zwift, Rouvy, Wahoo & Bike Computers

Track your speed and your pedaling cadence at the same time, with no magnets to align. The COOSPO BK9 set includes two slim wireless sensors: a speed sensor that clips onto your wheel hub, and a cadence sensor that attaches to your crank arm. Both send live data to your bike computer, smartphone, smartwatch, or indoor training app over Bluetooth 5.0 and ANT+. 🚴📊✨

Each sensor is ultra-thin at about 8.5mm and weighs only 8.4g (speed) and 8.6g (cadence). A small LED shows connection status, a replaceable CR2032 battery lasts up to about 300 hours according to the manufacturer, and IP67 protection handles rain and splashes. The set includes the silicone parts you need: a silicone case for the speed sensor, plus a silicone pad and two straps for the cadence sensor.

⚠️ Important Note
This set contains one speed sensor and one cadence sensor, and each measures only its own data. Please check that your bike computer, watch, or app supports Bluetooth or ANT+ speed and cadence sensors. The manufacturer notes that the Wahoo app does not allow two sensors from other brands to connect at the same time, so please check your app before ordering. IP67 does not cover soaking or high-pressure cleaning. Please check your hub and crank fit before ordering. ✅📲
