MaintenanceTips & Cycling Knowledge E-Bike Display Error Codes: Solutions for Error Code E36 The display screen of an electric bicycle (e-bike) is not only an essential source of information during a ride but also shows key data such as speed, battery level, mileage, and riding mode. This information helps riders better understand the status of their bike, ensuring a smooth and safe riding experience. However, beyond these functions, the display screen has another crucial role: when a fault occurs, it can display specific error codes that inform the rider about potential issues with the e-bike. Different error codes correspond to various types of faults, which may involve the motor, controller, braking system, or sensors, among other components. These error codes function as the e-bike’s “diagnostic tool,” helping riders quickly identify the root cause of the problem. Therefore, when an error code appears on the e-bike’s display, the rider must use the code’s meaning to conduct a thorough inspection of the bike and take appropriate measures to resolve the issue. Understanding Error Code E36 Error code E36 typically indicates an issue with the electric bike's motor or that the controller has detected a voltage beyond the safe operating range. This can be caused by several factors, including: Loose or Damaged Cables: The motor cables under the frame may be loose, broken or have poor contact, affecting power output. Display Malfunction: The bike's display could be faulty, misinterpreting or incorrectly communicating voltage levels to the controller. Controller Fault: The voltage detection circuit within the controller may be malfunctioning, preventing accurate transmission of voltage data, or leading to an incorrect detection of over/under-voltage conditions. Motor Malfunction: The motor may be damaged, resulting in improper function, and might need replacement. How to Respond to Error Code Alerts When an error code appears on your e-bike’s display, there’s no need to panic. Most issues can be addressed through basic checks and troubleshooting. Here are some general steps to follow: 1. Check Connections and Plugs Many fault codes stem from loose connections or damaged wires. Carefully inspect the connections of various components on your electric bike, paying special attention to the motor cables, particularly when an E36 code appears, as this is often caused by issues with the motor or motor control circuit. Check for any looseness, wear, or breakage in the motor wires, especially at the connection point under the frame. Corrosion on Plugs: Due to moisture or dirt, plugs may corrode over time. Regularly clean the plugs and ensure they are dry. 2. Reset the Display Sometimes, the bike’s display may need to be reset to clear temporary faults. Follow these steps to reset the display: Enter Settings Mode: Press and hold the “+” and “-” buttons simultaneously to access the display settings menu. Select P16 Parameter: Press the power button to navigate to the P16 parameter setting. Reset the Display: In the P16 parameter screen, press and hold the “-” button for about five seconds to reset the display. Save Settings: Once reset, press and hold the “+” and “-” buttons again to exit settings, then restart the display to check if the fault has been cleared. 3. Check the Controller If the problem persists after resetting the display and inspecting the cables, it may be related to a fault in the controller. Verify that the connections between the controller and other components (like the motor and sensors) are secure and that the controller itself is functioning correctly. For Literider models, the controller is located inside the fold of the frame. In Voyager, Rover, Hunter, and Discover models, the controller is situated near the pedals and crank. You’ll need to remove the black cover to check the controller. You can refer to these videos for guidance on how to perform this check. 4. Contact Professional Support If you are unsure how to proceed or if the issue remains unresolved after the above steps, please contact our customer service at customers@kingbullbike.com.

By following these steps, common issues can be resolved. However, if problems persist, reaching out to professional support with detailed information will ensure timely assistance. Remember, regular maintenance is key to keeping your e-bike running smoothly and preventing future faults. Read more
