If you encounter any issues with your PUCKIPUPPY Boxer ST Electric Bike, please refer to the following basic troubleshooting tips:
- Bike Not Turning On: Ensure the battery is fully charged and properly installed. Check that the battery is locked into the frame.
- Motor Not Assisting: Verify that the pedal-assist level is set above 0 on the LCD display. Check that the battery has sufficient charge. Ensure all electrical connections are secure.
- Brakes Squealing/Ineffective: Inspect brake pads for wear. Clean brake rotors if they are dirty. If issues persist, professional adjustment may be required.
