Feature: High quality. Dynamically monitor: This motorcycle tire pressure monitoring system dynamically monitors tire pressure and temperature, helps improve fuel efficiency, prolongs tire life, and enhances driver safety. Long battery life and reliable performance: Bluetooth-compatible external motorcycle TPMS sensors feature a long-lasting battery life of approximately 3 to 5 years. Easy operation via app: This Bluetooth TPMS supports Bluetooth 4.0 or higher and is operated through an app. The tire pressure monitoring system is designed for smartphones, supporting apps for both iOS and Android devices. During Bluetooth scanning, the app may request location permission; please allow this access as it is required by the Android system for Bluetooth functionality. High accuracy: Real-time monitoring with 2 TPMS sensors, waterproof and corrosion-resistant design, anti-theft technology, suitable for use in rainy conditions. High sensitivity and precise measurement of pressure and temperature. Easy setup: Installation can be completed in 3 simple steps within 10 minutes: 1. Remove tire valve caps and install anti-theft screws; 2. Attach the external sensor to the tire valve in the correct order; 3. Hold the sensor in place and tighten the anti-theft screw. Warning: Compatible with smartphones equipped with Bluetooth 4.0 or higher. Not compatible with devices having Bluetooth versions below 4.0. (Due to variations in hardware performance among Android phone manufacturers, data transmission delays may occur; this is considered normal.) Data is displayed on the smartphone. While driving, exercise caution when checking tire pressure and temperature on your phone. If tire pressure rapidly increases or decreases continuously, stop the vehicle and inspect the tire for potential issues. This product provides tire pressure and temperature readings but cannot prevent accidents caused by tire failure. It is recommended to use high-quality tires. Minor tire leakage resulting in gradual pressure loss over time is normal and unrelated to the installation of this product. Outer sensor installation: Each sensor has a unique ID code. Ensure each sensor is installed on the corresponding tire valve. Note: When tightening the sensor, open the app on your phone (select Auto Pair) and press the “Search” button simultaneously to complete the sensor pairing process quickly. Attention: Follow the markings and install each sensor on its designated tire. Keep the included installation tools (screws and wrench) in your vehicle for future sensor installation or removal. After installing the sensors, check for any tire air leakage.
