Feature: . 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: The 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 a mobile app. The tire pressure monitoring system is designed for smartphones and supports 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 accurate pressure and temperature readings. Easy setup: Install 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 position. 3. Hold the sensor in place and tighten the anti-theft screw securely. Warning: Compatible with smartphones supporting Bluetooth 4.0 or higher. Not compatible with phones with Bluetooth below version 4.0. (Due to variations in hardware performance among Android phone manufacturers, data transmission delays may occur; this is a normal condition.) Product 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, stop safely and inspect the tire for damage. This product provides tire pressure and temperature readings but cannot prevent accidents caused by tire failure. Always use high-quality tires. Minor tire leakage resulting in gradual pressure loss over time is normal and not related to the installation of this product. External sensor installation: Each sensor has a unique ID. Ensure each sensor is installed on the correct tire valve. Note: When tightening the sensor, open the app on your phone (select Auto Pair) and press the Search button simultaneously to complete sensor pairing quickly. Attention: Follow the markings and install each sensor on its corresponding tire. Keep the installation tools (screws and wrench) in your vehicle for future sensor installation or removal. After installing the sensors, check for any tire air leakage.
