3. Setup and Installation
Proper installation is crucial for accurate readings. Follow these steps carefully:
- Battery Installation: Install the two CR2032 batteries into the computer unit and the wireless transmitter. Ensure correct polarity.
- Mounting the Computer: Fix the bicycle computer onto your handlebar using the provided mount and cable ties. Ensure it is securely fastened and does not rotate during use.
- Mounting the Transmitter: Attach the wireless transmitter to the front fork of your bike.
- Attaching the Magnet: Secure the adhesive speed magnet to a spoke on your wheel.
- Positioning:
- Ensure the distance between the transmitter and the computer is less than 60cm.
- Ensure the distance between the transmitter and the magnet is no more than 1cm. Precise alignment is critical for consistent signal pickup.
- Wheel Circumference Setting: After installation, power on the computer. You will need to set the wheel circumference for accurate speed and distance measurements. Refer to the manual's specific section for programming this value. It is recommended to manually measure your wheel's circumference for best accuracy, rather than relying solely on default values.

4.3 Two Bike Settings (Bike A / Bike B)
This model supports settings for two different bikes. This allows you to store distinct wheel circumference values and track data separately for each bike. Consult the full user manual for detailed instructions on how to switch between Bike A and Bike B settings and how to program each profile.
5. Maintenance
To ensure the longevity and optimal performance of your RISEPRO Bicycle Computer, follow these maintenance guidelines:
- Cleaning: Wipe the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Water Resistance: The unit is waterproof, but avoid submerging it in water for extended periods or exposing it to high-pressure water jets.
- Battery Replacement: When the display becomes dim or erratic, replace the CR2032 batteries in both the computer and the transmitter. Ensure proper disposal of old batteries.
- Storage: If storing the computer for an extended period, remove the batteries to prevent leakage. Store in a cool, dry place.
6. Troubleshooting
If you encounter issues with your bicycle computer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No speed reading / Inconsistent readings | Magnet and transmitter misalignment or distance too large. Low battery in transmitter. | Ensure magnet and transmitter are within 1cm. Check and replace transmitter battery. Verify transmitter is securely mounted and not shifting. |
| Display is blank or dim | Low battery in computer unit. | Replace the CR2032 battery in the computer unit. |
| Computer does not stay clipped to handlebar | Mount not secure or insufficient grip. | Ensure cable ties are pulled very tight. Consider adding a thin piece of rubber under the bracket for better grip and to prevent rotation. |
| Difficulty entering programming mode or setting values | Incorrect button sequence or timing out. | Refer to the detailed programming section in the full user manual. Ensure you complete steps before the unit times out. |
| Inaccurate distance/speed readings | Incorrect wheel circumference setting. | Re-measure your wheel's circumference precisely and re-enter the value in the settings. |
