What Types of Displays Can Replace LCD Screens on E-Bikes?

E-bike riders have many display options to choose from when replacing standard LCD screens, depending on personal performance, aesthetics, and cost preferences.

OLED (Organic Light Emitting Diode) displays are an attractive solution with vibrant visuals due to their deep contrasts and rich colors. They offer excellent viewing experiences but are more expensive when subjected to direct sunlight or extreme conditions.

LED displays offer another solution. They are bright, energy-efficient, and generally more affordable than OLEDs. While they don't offer as much color depth, their brightness makes them easier to read under various lighting conditions—including sunlight—making LED displays an appealing choice for riders who prioritize clear visibility as well as energy savings.

TFT (Thin-Film Transistor) displays are:

Another viable choice.
Providing improved resolution and faster refresh rates when compared with standard LCDs.
Providing more explicit graphics and more precise data.

They represent an attractive balance between performance and cost, making them popular among riders looking for responsive screens without incurring OLED technology's premium cost tag.

Each display type offers distinct strengths, enabling riders to choose according to their specific aesthetic needs, durability requirements, or functionality requirements.

Display Compatibility and Protocols

Before buying a new display, check that it matches your e-bike’s system:

Communication Protocol: Most e-bikes use either a UART (serial) or CANBUS (network) protocol between the controller and display. CANBUS is common on high-end bikes, and it is often a closed system – only the manufacturer’s own displays are guaranteed to work. In other words, if your bike uses CANBUS, a third-party screen must explicitly support that protocol or come from the same brand. UART systems (found on many mid-range bikes) are simpler and often accept any display with the same connector/pinout.
Wiring and Connectors: Even if the protocol matches, the display’s connector must fit. E-bike wiring is not standardized, so you cannot assume a plug will match just by color. Always verify the connector type and pin assignments. For example, most waterproof Higo/Julet connectors use color-coded housings by pin count. Never force mismatched connectors – doing so can damage pins or electronics.
Firmware Compatibility: The controller and display each run firmware that dictates what data they exchange. A firmware mismatch can cause missing or incorrect info (speedometer, battery, assist level) or prevent the display from powering on. Many manufacturers lock their firmware to proprietary displays. Check if the manufacturer provides firmware updates or a list of compatible displays. If in doubt, choose a display known to work with your specific bike model.

Understanding your bike’s protocol and firmware is crucial. If you plug in a screen with the wrong protocol or incompatible firmware, it may power up but fail to show correct data or to let you change settings.

How to Replace Your E-Bike Display

If you’ve confirmed compatibility, follow these general steps to swap the display:

Gather Tools & Prepare: Turn off the e-bike and remove or disconnect the battery. Have appropriate tools ready (usually small Allen wrenches and zip ties).
Document the Setup: Before unplugging anything, take photos or notes of the existing display wiring and mount position. This helps later when connecting the new unit.
Remove the Old Display: Use an Allen key to unscrew the display’s mounting bolts. Carefully unplug its cable connector from the controller – most connectors have a locking sleeve that you twist or press to release.
Install the New Display: Position the new display on the handlebar and secure it with the mounting bolts. Align the connector pins and plug the new display’s harness into the bike’s wiring. Make sure the locking sleeve is fully threaded into place.
Reinstall Battery & Test: Reconnect the battery and power on the e-bike. Check that the display lights up and shows basic information (speed, battery level, pedal assist level, etc.). Verify that any buttons or touch inputs work correctly.
Secure Wires: Once everything is confirmed working, tidy up the cables with zip ties, ensuring they cannot snag on the frame or turn signals.

These steps assume a straightforward replacement. Always follow the new display’s manual if provided. Taking time to double-check each connection and testing before finishing ensures a smooth swap.

Troubleshooting Tips for Electric Bike Display Not Working Issues

If your electric bike's display suddenly ceases functioning, following these simple troubleshooting steps might restore everything to normal:

Check the Battery Connection: Make sure your battery is charged up and securely connected, as any looseness or depletion can lead to display issues.
Examine Wiring and Connectors: Inspect all visible wiring or connector damage for any signs of fraying or loose wires, which could disrupt the signal between your display screen and the bike's controller. Frayed or loose wiring could also impede proper communication.
Reset Your System: Sometimes, rebooting the system can resolve a problem quickly and efficiently. Switch off your bike, disconnect its battery for a short period, reconnect it, and then turn it back on.
Upgrade Firmware: Check for available firmware updates for the display on your e-bike display to prevent malfunctioning displays due to outdated software.
Test the Display Unit: If everything else seems normal, but something seems amiss with your display unit, testing it with another compatible bike or display may help identify its cause.

Following these steps, you can effectively identify and address most display issues without needing an expensive replacement.
