9. Troubleshooting
This section addresses common issues you might encounter with your e-bike.
| Problem | Possible Cause | Solution |
|---|---|---|
| Bike does not power on | Battery not charged or not properly seated; power button not pressed correctly. | Ensure battery is fully charged and securely installed. Press and hold the power button. |
| Motor not assisting | PAS level set to 0; throttle not engaged; brake levers engaged; loose motor connection. | Increase PAS level. Check throttle. Ensure brake levers are fully released. Inspect motor cable connections. |
| Short battery range | Under-inflated tires; frequent use of pure electric mode; heavy loads; cold weather. | Maintain correct tire pressure. Use PAS mode more often. Reduce load. Battery performance decreases in cold weather. |
| Brakes feel weak | Worn brake pads; loose brake cable; air in hydraulic system (if applicable). | Inspect and replace brake pads. Adjust brake cable tension. Consult a professional for hydraulic brake issues. |
