3. Setup and Installation

Follow these steps to properly install the speedometer magnet on your bicycle spoke:

1. Identify a suitable spoke on your bicycle wheel, typically on the front wheel.
2. Position the plastic housing of the magnet around the chosen spoke.
3. Insert the metal screw through the designated hole in the plastic housing and into the magnet unit.
4. Tighten the screw by hand until the magnet is securely fastened to the spoke. Ensure it is firm but do not overtighten to avoid damaging the plastic housing.
5. Adjust the magnet's position on the spoke so that it aligns with your bicycle computer's sensor. The gap between the magnet and the sensor should be minimal, typically a few millimeters, for accurate readings.

4. Operation

The speedometer magnet works in conjunction with a bicycle computer sensor. As the wheel rotates, the magnet passes by the sensor, generating a signal that the computer interprets to calculate speed and distance. No direct user operation is required for the magnet itself once installed correctly.

5. Maintenance

To ensure optimal performance and longevity of your speedometer magnet:

• Regular Cleaning: Periodically wipe the magnet and its housing with a damp cloth to remove dirt and grime. Avoid harsh chemicals.
• Check Tightness: Routinely inspect the mounting screw to ensure the magnet remains securely attached to the spoke. Tighten if necessary, but do not overtighten.
• Inspect for Damage: Check the plastic housing for any cracks or damage that could affect its secure fit or the magnet's position.

6. Troubleshooting

If your bicycle computer is not registering speed or distance, consider the following:

• No Reading: Ensure the magnet is correctly aligned with the sensor on your bicycle computer. The gap between the magnet and sensor should be small (typically 1-5mm). Adjust the magnet or sensor position as needed.
• Intermittent Readings: Check if the magnet is loose on the spoke. Tighten the mounting screw if it has become loose. Also, verify that the sensor itself is securely mounted and not shifting.
• Magnet Lost: If the magnet has fallen off, a replacement unit will be required.
