Compatibility
Avoid the guesswork: if you see the "Yolin" logo on the back of your original display, our replacement is guaranteed to be a perfect fit.
As the original manufacturer of Yolin displays, we maintain the complete technical database for every serial number and protocol configuration. Most compatibility issues arise because sellers offer generic "universal" displays that fail to communicate with your specific e-bike controller.

The Yolin YL-91F-V is a 4-inch vertical LCD display designed for riders who prefer larger and more visible ride data. The expanded screen area allows riding metrics to be presented more clearly during commuting or long-distance rides.
Vertical Format for Focused Data Flow
Unlike horizontal models in the Yolin lineup, the YL-91F-V adopts a vertically structured interface. This format places primary ride data in a natural top-to-bottom hierarchy, helping riders process speed and system information quickly without scanning across the screen.
- Large vertical real-time speed display (mph/kmh system dependent)
- Multi-level PAS indication
- Battery level and voltage monitoring
- Integrated error code diagnostics
- Structured data separation for reduced visual clutter

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.
