  • 2. Selecting Riding Mode

    The KORNORGE electric bike offers three riding modes: manual, pedal-assisted, and pure electric. Use the mode selection buttons on the LCD display to switch between assist levels (1-3) for pedal-assist mode. If the display shows "0" mode, the throttle will not respond; you must select an assist level (1-3) to engage electric power.

  • 3. Using the Throttle

    Once an assist mode is selected (1-3), gently twist the throttle on the right handlebar to engage the electric motor and accelerate. The bike will provide power based on the selected assist level and throttle input.

  • 4. Braking

    The bike is equipped with dual disc brakes for effective stopping power. Apply both brake levers evenly to slow down or stop. Regular inspection of brake pads and cables is recommended.

Maintenance

  • 1. Battery Care

    The 48V 15.6AH removable battery is UL2849-certified. Charge the battery fully before first use and after each ride. It takes approximately 7-8 hours for a full charge. Store the battery in a cool, dry place when not in use. To remove the battery, use the key to unlock it and slide it out. To reinstall, slide it back in and lock it with the key.

  • 2. Tire Pressure

    Regularly check tire pressure to ensure it is within the recommended range specified on the tire sidewall. Proper tire pressure improves ride comfort, efficiency, and safety.

  • 3. Brake System Inspection

    Periodically inspect the dual disc brakes for wear on the pads and proper tension of the brake cables. Adjust or replace components as necessary to maintain optimal braking performance.

  • 4. General Cleaning

    Clean the bike regularly with a damp cloth. Avoid using high-pressure water jets directly on electrical components. Lubricate the chain periodically to ensure smooth operation.

Troubleshooting

If you encounter any issues with your KORNORGE electric bike, refer to the common problems and solutions below. For more complex issues, please contact customer support.

  • Bike Not Turning On

    Ensure the battery is fully charged and properly installed. Check that the battery switch is in the "on" position. Long-press the power button on the LCD display to activate it.

  • Motor Not Engaging

    Verify that the display is on and an assist mode (1-3) is selected. The motor will not engage if the display is in "0" mode. Check all cable connections for looseness.

  • Low Power or Short Range

    This typically indicates a low battery charge. Ensure the battery is fully charged before each ride. Extreme temperatures can also affect battery performance and range.

  • Brakes Squeaking or Not Effective

    Inspect brake pads for wear and replace if necessary. Check brake cable tension and adjust as needed. Ensure disc rotors are clean and free of oil or grease.
