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 the "Yolin" on the back, it is guaranteed to be a perfect fit. As the original manufacturer, we have the database to verify the exact protocol. 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 100% 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?
Don't worry! We offer a Compatibility Guarantee. If the display does not work with your e-bike due to compatibility issues, we will provide a full refund. You can shop with zero risk.
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.
