Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your YOUNICE Motorcycle Tire Pressure Monitoring System (TPMS) MT20. This system is designed to enhance driving safety by monitoring your motorcycle's tire pressure and temperature in real-time, helping to prevent accidents caused by tire issues.
Safety Information
- Always ensure sensors are securely fastened to prevent detachment during operation. Loose sensors can be a hazard.
- Do not attempt to disassemble or repair the device yourself. Refer to qualified personnel for service.
- Regularly check tire pressure with a calibrated gauge, even with the TPMS installed, for optimal accuracy and to confirm TPMS readings.
- Pay attention to all alarm signals and address them promptly. Ignoring alarms can lead to dangerous situations.
- Ensure the display unit is mounted in a position that does not obstruct your view of the road or interfere with motorcycle controls.

Product Overview
Display Unit
The display unit features a color LCD screen for clear visibility of tire pressure, temperature, time, and battery level. It includes a solar panel for charging and a magnetic charging port for convenient power options.
External Sensors
Two external sensors are provided for monitoring the front (FW) and rear (RW) tires. These sensors are designed for easy installation on the tire valve stems and are built to be waterproof.
Setup and Installation
1. Charging the Display Unit
Before first use, fully charge the display unit using the provided USB cable. The unit also supports automatic solar charging when exposed to sunlight, ensuring continuous power supply.
2. Mounting the Display Unit
- Attach the mounting bracket to your motorcycle's handlebar or another suitable, secure location.
- Secure the display unit onto the bracket. Adjust the angle for optimal visibility without obstructing your view or interfering with motorcycle controls.
3. Installing the External Sensors
- Identify the front (FW) and rear (RW) sensors. Ensure they are installed on the correct tires.
- Unscrew the original valve cap from the tire valve stem.
- Screw an anti-theft nut onto the tire valve stem.
- Screw the corresponding sensor (FW for front, RW for rear) onto the valve stem until it is hand-tight.
- Using the provided wrench, tighten the anti-theft nut against the sensor to secure it and prevent theft.
- Check for any air leaks around the sensor and valve stem.
Operation
Power On/Off
The system features an automatic start/stop energy-saving mode. It will automatically turn on when the motorcycle starts moving and enter sleep mode after 10 minutes of inactivity to conserve power.
Display Information
The color LCD display shows the following real-time information:
- Front Wheel (FW) Tire Pressure
- Front Wheel (FW) Tire Temperature
- Rear Wheel (RW) Tire Pressure
- Rear Wheel (RW) Tire Temperature
- Current Time/Clock
- Battery Level of Display Unit
- Solar Charging Indicator
Alarm Modes
The system provides 6 distinct alarm modes to alert you to potential tire issues, updating data every 3 seconds:
- Air Leak Alarm: Alerts to rapid air loss from a tire.
- High-Pressure Tire Alarm: Alerts when tire pressure exceeds the user-defined high limit.
- Low-Pressure Tire Alarm: Alerts when tire pressure falls below the user-defined low limit.
- High-Temperature Tire Alarm: Alerts when tire temperature exceeds the user-defined high limit.
- Low-Battery Alarm: Indicates the display unit's internal battery is low and requires charging.
- Sensor Signal Loss Alarm: Alerts if communication with one or both sensors is lost.
Setting Parameters (Pressure/Temperature Units, Alarm Thresholds)
Use the "Select" and "Switch/Select" buttons on the side of the display unit to navigate through settings. Refer to the included printed manual for detailed instructions on adjusting pressure units (PSI/Bar), temperature units (°C/°F), and alarm thresholds for high/low pressure and high temperature to suit your preferences and motorcycle specifications.
Maintenance
- Cleaning: Wipe the display unit and sensors with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the device.
- Battery: The display unit is rechargeable via solar power and magnetic USB. Ensure it receives adequate sunlight for solar charging or connect it to a USB power source when needed. Sensors have internal batteries that are not user-replaceable. If a sensor battery depletes, the sensor will need to be replaced.
- Water Resistance: The display unit is IP67 waterproof, meaning it can withstand immersion in water up to 1 meter for 30 minutes. However, avoid prolonged submersion or exposure to high-pressure water jets to ensure longevity.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display not turning on | Low battery; System in sleep mode | Charge the unit via USB or expose it to direct sunlight for solar charging. Start riding the motorcycle to activate the system from sleep mode. |
| No sensor data / Signal loss alarm | Sensor not installed correctly; Sensor battery depleted; Electromagnetic interference | Re-install the sensor, ensuring it is tight and correctly positioned. If the issue persists, the sensor battery may be depleted; contact support for sensor replacement. Move away from strong electromagnetic sources if possible. |
| Inaccurate readings | Sensor not calibrated; External factors; Incorrect unit settings | Verify readings with a reliable, calibrated tire gauge. Ensure sensors are correctly paired. Check that the display unit's pressure and temperature units are set correctly (PSI/Bar, °C/°F). |
| Display leaks / Water ingress | Damage to unit; Exceeded IP67 limits (e.g., prolonged deep submersion) | Discontinue use immediately to prevent further damage. Contact customer support for assistance and potential replacement under warranty. |
