Introduction
The YoLin YL81F EBike LCD Display is a smart, bezel-less control panel designed for electric bicycles and scooters. It provides essential riding information and allows for customization of various parameters to enhance your e-bike experience. This manual will guide you through the installation, operation, and maintenance of your YL81F display.
Setup and Installation
Before installation, ensure your e-bike system is powered off. The YL81F display is compatible with 36V, 48V, and 52V e-bike systems.
Mounting the Display
- Identify a suitable location on your handlebar for the display and the separate control unit.
- Securely attach the display bracket to the handlebar. The mounting clamp diameter is 31.8mm.
- Ensure the display is positioned for optimal visibility and the control unit is easily accessible.
Wiring Connections
Connect the display to your e-bike controller using the provided waterproof connector. Pay close attention to the wire color functions:
| Pin No. | Cable Color | Function |
|---|---|---|

- Storage: When not in use for extended periods, store the display in a dry place with a temperature between -30℃ and 70℃.
Troubleshooting
If you encounter issues with your YL81F display, refer to the following common troubleshooting tips:
- Display Not Powering On:
- Check all wiring connections, especially the power cord (Red) and ground wire (Black), to ensure they are secure.
- Verify that your e-bike battery has sufficient charge.
- Ensure the display's power button is pressed correctly.
- Incorrect Speed/Mileage Readings:
- Confirm that the wheel diameter setting in the display's parameters matches your e-bike's wheel size.
- Check the speed sensor connection on your e-bike.
- Display Shows Error Codes:
- The display is equipped with an error code display function. If an error code appears, note it down.
- Consult your e-bike's controller manual or contact customer support with the specific error code for diagnosis.
- Display Not Communicating with Controller:
- Critical Note: The YL81F display operates on a specific communication protocol (default lithium II protocol). If the display was purchased separately from your e-bike, it is crucial to verify compatibility with your e-bike's controller protocol. Incompatible protocols will prevent proper function. Contact the seller or manufacturer to confirm compatibility if you suspect this is the issue.
- Check the data transmission lines (Green RX, Yellow TX) for secure connections.
