6. Troubleshooting

This section addresses common issues you might encounter with your Jasion Thunder Electric Bike.

6.1 Battery Indicator Discrepancy

Issue: The battery indicator on the display shows a mix of red, yellow, and green lights when fully charged, instead of all green.

Possible Cause: This could be a calibration issue with the battery management system (BMS) or a display error.

Solution:

1. Ensure the battery is fully charged until the charger indicator turns green.
2. If the issue persists, try fully discharging the battery (by riding until it's low) and then fully recharging it. This can sometimes recalibrate the BMS.
3. If the problem continues, contact Jasion customer support for further assistance.

6.2 Motor Not Engaging / No Power Assist

Possible Causes:

• Battery not charged or not properly seated.
• Power switch is off.
• Brake levers are engaged (some e-bikes have safety cut-offs).
• Loose electrical connection.

Solutions:

1. Check battery charge level and ensure it is securely installed.
2. Verify the bike's power switch is in the 'ON' position.
3. Release both brake levers completely.
4. Inspect visible cable connections for looseness. If unsure, contact support.

6.3 Unusual Noises During Operation

Possible Causes:

• Loose components.
• Brake rub.
• Chain issues (dry, dirty, or misaligned).

Solutions:

1. Stop riding and visually inspect the bike for any loose parts.
2. Check if brake pads are rubbing against the rotors. Adjust if necessary.
3. Clean and lubricate the chain. Ensure it is properly seated on the gears.
