Compatibility
Simply flip over your original display. If it says "Yolin" on the back, it's an original Yolin product. Since we made it, your specific display data is already in our system.
Most compatibility issues arise because sellers offer generic "universal" displays that fail to communicate with your specific e-bike controller.

FAQS
How do I know if this display will work with my e-bike?
The easiest way to check is to look at your original display. If you see "Yolin" on the back, that means it's our product. As the original manufacturer, we already have your display's information in our database.
If you no longer have the old display, just send us your e-bike model or controller model, and we’ll check compatibility for you.
Is this plug and play?
Yes, it is Plug and Play. We handle all the technical programming here so you don't have to. There is no need to connect to a computer or change any settings. Just install the display, plug in the connectors, and you are good to go!
What if the display isn't compatible with my bike? Can I return it?
If the correct original display code is provided and the display is defective or fails to work due to a manufacturing fault on our end, a full refund will be issued.
Exclusions:
External Damage: Error codes caused by damaged or malfunctioning e-bike components (e.g., motor, controller, wiring) are not display defects. The display is functioning as intended by alerting the user to external issues, and these cases do not qualify for a refund.
Custom Products: Each display is custom-programmed exclusively for your serial number and cannot be used on other bikes. Because these are 1-on-1 personalized products that cannot be resold, we cannot accept returns due to "change of mind," incorrect codes provided by the customer, or errors caused by other damaged bike parts.
Can I change the speed limit or settings (P-parameters) myself?
Yes, while it comes ready to use, our displays allow you to access basic settings (like wheel size, speed limits, or pass-voltage) directly through the menu. We can provide a manual if needed.
Can I choose a specific connector type?
Absolutely! We carry every type of connector. Usually, we send the one that fits your bike's original setup automatically. But if you need a different one, just send us a message before shipping, and we’ll change it for you right away.

Best service and part is perfect
I got my Ebike Display and it worked perfectly. So glad I found Yolin. When I was looking around for a replacement display, every seller said they wouldnt sell to me unless I knew the display protocol. I also could not find anyone that would tell me where I would find the numbers that lists the protocol. Then came Yolin and they made it so easy for me.
Ther display was the exact replacement of what I had. Put it on the bike and it fired right up! Nice bright display. Well done!
The support team was incredibly helpful. Their response time was quick , and the guidance provided was clear and easy to follow. I appreciated their patience and willingness to go the extra mile, leaving me with a positive experience. I highly recommend their services.
