To manually measure, mark a spot on your tire and roll the wheel one full revolution, then measure the distance. Input this value into the computer. For example, if your tire is 26" x 1.95", input 2055.
3. Unit Setting (KM/H or M/H)
After setting the wheel circumference, you can select your preferred unit of measurement (kilometers per hour or miles per hour) using the right button and confirming with the left button.
4. Clock Setting
Set the clock to either 12-hour or 24-hour format, then adjust the hour and minute using the right and left buttons respectively.
5. Handlebar Mount Installation
Attach the bracket to your bicycle's handlebar using the provided zip ties. Ensure it is securely fastened and positioned for optimal viewing.


6. Sensor and Magnet Installation
Install the wireless sensor on the front fork and the magnet on a spoke of the front wheel. The distance between the sensor and magnet should be less than 1.5mm for accurate readings. Use the provided zip ties to secure the sensor.
7. Signal Test
After installation, spin the front wheel to verify that the speed readings appear on the computer. If no readings are displayed, check the sensor and magnet alignment and distance. Ensure the distance between the computer and the sensor is less than 60cm.
Operating Instructions
The Lixada Bicycle Cycling Computer offers 16 functions to monitor your cycling performance. Use the buttons on the device to navigate through different modes and settings.
Display Modes
- SPD (Speedometer): Displays current speed.
- ODO (Odometer): Records total distance traveled (0.001-99999km/m).
- DST (Trip Distance): Shows distance covered in the current trip.
- MXS (Maximum Speed): Records the highest speed achieved.
- AVS (Average Speed): Calculates the average speed of the current trip.
- TM (Elapsed Time): Tracks the duration of the current trip.
- CLK (Clock): Displays time in 12-hour or 24-hour format.
- Backlight: Illuminates the display for visibility in low-light conditions.
- SCAN: Cycles through various display modes automatically.
Resetting Data
To reset trip-specific data (DST, TM, MXS, AVS), press and hold the left button for 3 seconds while in the respective mode. This will clear the current trip data.
Maintenance
Battery Replacement
The computer and sensor use CR2032 batteries. When the display becomes dim or erratic, it's time to replace the batteries. Ensure correct polarity during installation.
Waterproof Rating
The device has an International Protection Rating of IP4, indicating it is protected against splashing water from any direction. It is not designed for submersion.
Sensor and Magnet Distance
Regularly check that the distance between the wireless sensor and the magnet on the spoke remains less than 1.5mm. If the distance increases, readings may become inaccurate or stop altogether. Adjust as needed.
Troubleshooting
- No Speed Reading: Check the distance between the sensor and magnet. Ensure it is less than 1.5mm. Verify batteries are correctly installed and charged.
- Screen Difficult to Read in Daylight: Some users report screen reflectivity issues in bright sunlight. Adjust the viewing angle or consider using the backlight in shaded conditions.
- Backlight Not Staying On: The backlight may require frequent recharging or manual activation depending on the mode. Refer to the operating instructions for backlight settings.
- Inaccurate Readings: Re-verify the wheel circumference setting. Ensure the sensor and magnet are securely mounted and their distance is optimal.
- Missing Components: If any essential part (e.g., magnet) is missing upon arrival, contact the seller for support.
