7. Troubleshooting

This section addresses common issues you might encounter with your Deepower DP-A2 electric bike. For problems not listed here, please contact customer support.

• Bike not powering on: Check if the battery is fully charged and properly installed. Ensure the battery switch is in the 'on' position.
• Motor not assisting: Verify that the pedal assist level is set above zero on the LCD display. Check for any error codes on the display.
• Brakes feel weak: Inspect brake pads for wear. Adjust brake cable tension. If issues persist, professional inspection is recommended.
