Common questions about manuals, registration, and support for this brand.
On most Yolin models (like the YL80C or YL81F), you can access the personalized parameter settings by pressing and holding the Plus (+) and Minus (-) buttons simultaneously for about 2 seconds while the display is powered on and the bicycle is stationary.
To reset the trip odometer, enter the main settings interface (usually by holding Plus and Minus). Once in the menu, look for the option to reset trip data or hold the combination of buttons specified in your model's manual (often Plus and Minus again) to clear the current trip distance.
Walk Boost mode allows the e-bike to move at a slow, constant speed (usually 6km/h) to assist you while pushing the bike. It is typically activated by long-pressing and holding the Minus (-) button.
Error codes indicate specific system faults. Common codes include: E001 (Controller failure), E004 (Throttle failure), E005 (Brake failure), and E006 (Motor phase failure). Refer to your specific model's user manual schedule for a complete list.
