Setup
1. Main Unit Installation
- Attach the bracket to your bicycle handlebar using the provided screws and nuts.
- Slide the main unit onto the bracket until it clicks securely into place.
- Connect the wired extension controller for the horn and light to the main unit.
2. Speed Sensor and Magnet Installation (Wireless Version)
For accurate speed and distance tracking, proper installation of the wireless speed sensor and magnet is crucial.
- Magnet Placement: The best position for the magnet is on the top of a bicycle spoke. The non-circular structure of the spoke top helps prevent the magnet from swinging, ensuring a stable wireless signal.
- Distance: Maintain a distance of approximately 6mm between the magnet and the speed sensor. If the distance is too close, it may lead to unstable readings.
- Alignment: Ensure the magnet is aligned with the center position of the transmitter (speed sensor) as shown in the diagram for optimal signal stability and accuracy.
- Sensor Battery: The wireless launcher (speed sensor) requires a CR2032 button cell battery.

Bike LED Light
The 800-lumen headlight provides excellent visibility. It features dual T6 LEDs for both spotlight and floodlight capabilities.
Dual T6 LEDs provide both spotlight and floodlight for comprehensive illumination.
Lighting Modes: There are 4 modes of brightness, controlled either by the wired extension controller or the button on the main unit:
- 100% brightness for 1 LED
- 100% brightness for 2 LEDs (will switch to 60% brightness if no movement after 3 minutes)
- 60% brightness for 2 LEDs
- 2 LEDs flash (SOS mode)
Press the "LED" button on the wired controller or the power button on the main unit to cycle through the modes.

The headlight features an anti-glare design to prevent blinding oncoming drivers, enhancing safety for city riders and commuters.
Anti-glare design ensures visibility without blinding others.
Bike Horn
The 120dB electronic horn provides a clear warning sound. It is controlled via the wired extension controller.
Sound Modes: There are 3 kinds of sound modes. To select your desired sound mode, long press the "SPK" button on the wired controller for 5 seconds.
The wired controller allows easy access to the horn function.

To turn the backlight on or off, press the SET key for 2 seconds.
The bright backlight ensures clear visibility of data in all conditions.
Charging
The main unit has a built-in 4000mAh rechargeable lithium battery. It supports USB Type-C charging.
- Connect the provided USB charging cable to the Type-C port on the device.
- You can charge the device using a mobile phone charger or a power bank.
- Important: Do not charge the device using a computer USB port, as this may cause continuous restarts.
- A full charge takes approximately 4 hours.
Recommended charging methods for the device.
The device features a built-in 4000mAh battery for long endurance.
Maintenance
- Cleaning: Wipe the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Water Resistance: The device is IPX6 water-resistant, meaning it can withstand strong jets of water. However, it is not recommended for prolonged use in heavy rain or submersion.
- Battery Care: Charge the battery in a timely manner when it is low. If the battery is completely exhausted, all stored data may be lost, and the device will revert to factory settings upon recharging.
- Data Reset:
- Clear Trip Distance (DST), AVS, MXS, TM, and CAL: Long press the Power button for 3 seconds. This will also turn off the bike light and computer.
- Clear All Data: Long press both the SET and MODE buttons for 10 seconds.
- Reset Circumference, Weight, Clock: Press and hold the MODE key and SET key simultaneously for 5 seconds to enter the setting state.
The device is water-resistant, but avoid prolonged exposure to heavy rain.
Troubleshooting
- No Speed Display / Computer Not Finding Sensor:
- Ensure the distance between the main unit and the speed sensor is below 80 cm.
- Verify the distance between the speed sensor and the magnet is approximately 6mm.
- Check that the magnet is aligned with the center of the sensor. Incorrect alignment can lead to abnormal or zero speed readings.
- After battery installation, the speed sensor needs to work continuously for 1 minute to recognize the new sensor due to ID coding technology. Test for one minute to confirm proper function.
- Avoid electromagnetic interference from household appliances, high-voltage wires, transformers, charging stations, elevators, etc., as these can affect wireless operation and cause zero speed display.
Ensure the magnet is aligned with the center of the sensor.
- Inaccurate Speed Readings (e.g., speed jumps to 99km/h):
- This often indicates incorrect installation or calibration. Reboot the computer and ensure the correct tire circumference is set.
- Double-check that the magnet is precisely aligned with the center of the sensor. Misalignment can cause abnormal speed readings.
- GPS Functionality (for LIG001 GPS model):
- The GPS code meter will automatically search for satellite signals after switching on. The first time you use it, or in an unfamiliar area, it may take 1-3 minutes to complete positioning.
- The satellite icon will stop flashing once the satellite search is complete. Subsequent use will be faster due to satellite memory.
- The GPS version does not require a sensor connection for speed tracking.
GPS models offer advanced positioning without external sensors.

User Tips
- Handlebar Space: The 3-in-1 design is excellent for saving handlebar space compared to separate devices.
- GPS Accuracy: For GPS models, ensure you are in an open area for the initial satellite connection. Once connected, it generally works very well.
- Horn Usage: The loud horn is effective for warning pedestrians and vehicles, especially in busy areas or during overtakes.
- Battery Life: The 4000mAh battery provides good endurance, especially when the headlight is not continuously on.
- Light Modes: Experiment with the different light modes to find the best setting for your riding conditions (e.g., 60% brightness for urban areas, 100% for dark trails, SOS for emergencies).
