Sensor Mounting (No Magnets Required)
The BK9 sensors do not require magnets for operation, simplifying installation.
Cadence Sensor Installation:
- Attach the cadence sensor to the inside of your bike's crank arm using the provided silicone ring or field buckle. Ensure it is securely fastened and does not interfere with pedaling.
Speed Sensor Installation:
- Attach the speed sensor to the hub of either the front or rear wheel using the provided silicone ring or field buckle. Ensure it is firmly attached and does not obstruct wheel rotation.
- Важна напомена: If your bike has a dynamo hub, it is recommended to mount the speed sensor to the spokes near the rim for accurate readings, as dynamo hubs can interfere with hub-mounted sensors.

Упутство за употребу
Connecting to Cycling Computers and Apps
The COOSPO BK9 sensors support both Bluetooth 5.0 and ANT+ connectivity, allowing them to pair with a wide range of devices and applications.
- Активирајте сензор: Gently shake or rotate the sensor to wake it up. A small LED indicator will flash to confirm it is active.
- Enable Bluetooth/ANT+: Ensure Bluetooth is enabled on your smartphone or ANT+ is active on your cycling computer.
- Open Application/Device: Launch your preferred cycling application (e.g., Rouvy, Peloton, Wahoo, CoospoRide) or turn on your GPS bike computer.
- Pair Sensor: Navigate to the sensor pairing or device connection section within your app or cycling computer settings.
- Изаберите сензор: The sensor should appear in the list of available devices. Select it to pair. For cadence, it might appear as "BK9C" and for speed, "BK9S".
- Потврдите везу: Once paired, the app or device will typically display a "connected" status.

Одржавање
Чишћење и њега
The COOSPO BK9 sensors are IP67 waterproof, meaning they are protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. However, to ensure longevity:
- Обришите сензоре огласомamp cloth after use, especially after riding in wet or dusty conditions.
- Avoid soaking the sensors in water or cleaning them with high-pressure water jets.
- Не користите јаке хемикалије или абразивна средства за чишћење.

Решавање проблема
- Сензор се не повезује:
- Ensure the sensor battery is not depleted. Replace if necessary.
- Wake up the sensor by shaking or rotating it.
- Verify Bluetooth (for apps) or ANT+ (for cycling computers) is enabled on your device.
- Уверите се да је сензор у домету вашег пријемног уређаја.
- Try restarting your smartphone or cycling computer.
- Ако користите апликацију за паметни телефон, уверите се да упаривање вршите унутар саме апликације, а не директно преко Bluetooth подешавања телефона.
- Inaccurate Speed Readings:
- If mounted on a dynamo hub, reposition the speed sensor to the spokes near the rim.
- Ensure the sensor is securely mounted and not shifting during rides.
- Wahoo App Connectivity:
- The Wahoo app may not allow pairing of two third-party cycling sensors simultaneously. If you are experiencing issues, try pairing one sensor at a time or use a different compatible application.
- General Connectivity Issues with Smartphone Apps:

Image: A visual guide demonstrating the correct and incorrect methods for connecting the COOSPO BK9 sensor to smartphone applications. The correct method involves pairing within the app, while the incorrect method shows attempting to pair directly via phone settings.
Always connect the sensor directly through the cycling application's pairing menu, not through your phone's general Bluetooth settings. Connecting via phone settings can prevent the app from recognizing the sensor.
