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.

Remember, regular maintenance is key to keeping your e-bike running smoothly and preventing future faults. Read more

Tips & Cycling Knowledge The Best Bikepacking Route for Fall and Winter: Baja Divide The Baja Divide is a stunning route that stretches between the Pacific Ocean and the Sea of Cortez, passing through historic Spanish mission sites, shaded oases with plenty of water, remote ranches and fishing villages, bustling highway towns, and every major mountain range in Baja California. This route, made up of miles of beautiful desert tracks, is the perfect destination for bikepacking during the fall and winter. The complete route is about 3473 miles, and divided into 20 individual segments, defined by resupply points. If you're choose one segment to enjoy the freedom of cycling while easily tackling rugged terrain, the Kingbull Literider folding electric bike is your ideal companion. With its powerful 750W motor, portable folding design, and comfortable riding experience, Literider helps you conquer any terrain with ease while offering impressive range, so you can focus on the scenic beauty without worrying about fatigue on long rides. Baja California and Baja California Sur are two of the least populated areas in Mexico, particularly away from the border regions near Tijuana and Mexicali. Vast deserts, rugged coastlines, and a taste of the wild west make this a prime destination for those seeking adventure and natural beauty. Route Features Throughout the Baja Divide, you'll find numerous dirt roads that cut through fishing villages and ranches. However, some parts of the route receive little maintenance and are often affected by weather. Mountain roads are rugged, and sandy tracks add to the challenge. Plus bikes with 3.0” tires are recommended for navigating the sand. Tubeless tires are essential to avoid cactus thorns. The rhythm of life on the Baja Divide revolves around cycling, camping, and resupplying. Wild camping is a highlight of this route, and while resources are limited, the route is designed with enough resupply points to make a self-supported tour feasible. On some sections, you may need to carry 2-3 days of food and 10-12 liters of water. Fortunately, with an electric bike like the Kingbull Literider, you'll have the added power and range to lighten your load and make your journey more enjoyable. Best Riding Time The best time to ride the Baja Divide is during winter, particularly from November to March. The dry, warm climate is ideal for riding, while summer temperatures can be extreme, and late summer to fall brings hurricane season. Cultural and Culinary Experience Along the Baja Divide, you'll experience a mix of rural and urban life, as well as diverse landscapes. The route passes several historic Spanish mission sites, often located near water and shaded by date palms, offering a perfect blend of history and nature. You’ll also pass through bustling highway towns like Colonet, Vincente Guerrero, Vizcaíno, and Ciudad Constitución, where you can sample delicious Mexican food such as tacos, ceviche, and fresh pastries. Scenery and Camping The scenery along the Baja Divide is breathtaking, with deserts, canyons, towering cacti, cirios trees, and mountain ranges dominating the landscape. The Sea of Cortez offers stunning views where the desert meets the sea. If you're willing to carry extra food and water, you can also enjoy remote beach camping at some of the secluded beaches along the route. Practical Information Navigation: Since most roads along the Baja Divide are unmarked and unnamed, GPS navigation is highly recommended. Equipment: Wide tires (at least 3.0”) and a tubeless tire system are essential. Supplies and Water: On certain stretches, you may need to carry up to 10 liters of water and plan ahead, especially in areas without ATMs like Cataviña, Bahía de los Ángeles, and San Ignacio. Visa Information: Most travelers from the U.S., Canada, Australia, the EU, and South American countries can enter Mexico visa-free for up to 180 days. However, for stays longer than 7 days, a tourist visa fee of around $20 is required at the border, along with a passport. Conclusion If you love wilderness adventures and are seeking a winter escape, the Baja Divide is an outstanding choice. With vast deserts, historical mission sites, rugged coastlines, and the welcoming culture of Mexico, this route will leave you with unforgettable memories. Go light, embrace nature, and with a bike like the Kingbull Literider, you'll enjoy the ride with extra power and less worry. Read more
