When you're shopping for ebike motor, controller, and display upgrades, the screen has to match your controller, handlebar diameter, and power requirements. Here are four LCD displays that take different approaches to getting ride data in front of you.
What to check before you choose a display
Ebike displays are not universal. Three things matter most: controller compatibility, plug pin configuration, and handlebar clamp diameter. The screens here differ in plug pin count and mounting options, so matching these details to your bike is more important than the listed price. If your controller isn't compatible, an otherwise compatible-looking screen may not power on or may show incorrect data.
Quick take
If you want the lowest price and a compact display, the S866-SM fits. Need one screen that lists 24V, 36V, 48V, and 60V? The M5 5PIN is the most voltage-flexible option. Want a display that adjusts vertically and fits several handlebar clamps? The UART 2 M6C is made for that. If a color screen with detailed ride data matters more than price, the Bigstone C600E is the display to consider.
Listed-price comparison
| Display | Listed Price | Price Bar |
|---|---|---|
| M5 5PIN Speed Meter | $36.48 | |
| UART 2 M6C Display | $38.99 | |
| Bigstone C600E Display Kit | $75.99 | |
| S866-SM Display | $23.99 |
Decision matrix
| If you need... | Best match | Why |
|---|---|---|
| A low-cost display for a compact handlebar | S866-SM | Compact display for narrower bars |
| One screen that supports multiple voltage ratings | M5 5PIN | ABS housing with waterproof connector |
| Vertical angle adjustment and several holder sizes | UART 2 M6C | Full angle adjustment, multiple handlebar clamps |
| A color display with more ride detail | Bigstone C600E | 3.5 TFT screen, error codes, distance/travel time |
M5 5PIN LCD Speed Meter Display
At $36.48, this display is the only one here that lists 24V, 36V, 48V, and 60V support in its title. The ABS housing and waterproof connector make it a practical replacement for an ebike that sees wet weather. It comes with two mounting options: 31.8mm or 22.2mm, so you can match the clamp to your bars. The limitation is that it uses a 5-pin plug, not a 6-pin plug; if your harness expects six pins, you'll need to adapt or choose another screen.
UART 2 M6C Electric Bike LCD Display Meter
The M6C display costs $38.99 and uses the UART2 protocol, so it must match your controller's protocol to work properly. Its stand-out feature is full vertical angle adjustment plus a holder that fits multiple handlebar diameters, making it a strong option if you're moving it between bikes. The screen shows battery, headlight, walk mode, PAS level, speed, trip, running time, and error warnings. The catch is that the default speed is set to unlimited; if your controller limits speed, the display can only show that limited value.
Bigstone LCD C600E Display Kit Conversion
At $75.99, the Bigstone C600E is the most expensive display in this comparison, and it's the only one with a 3.5-inch TFT color LCD (320x480). It also adds backlight control, error-code readouts, distance, travel time, and speed in KM/H or MPH. The title lists 36/48V operation, and it is a conversion display kit. The trade-off is protocol compatibility: ebike brands use different LCD protocols, so you need to confirm the exact protocol before buying, otherwise the screen may not pair with your controller.
For E-Bike LCD Display S866-SM
The S866-SM sells for $23.99, the lowest price in this group. It is a compact UART2 display sized 80.5 x 47.5 x 9.2mm and mounts to a 22.2mm handlebar, which suits narrower bars. It includes battery indicator, headlight control, boost, PAS levels, speed, trip/total mileage, running time, fault indicator, walking mode, and metric/imperial switching. As with other UART2 models, make sure your controller is compatible; the default speed is unlimited, so a controller speed limit will show only up to that limit.
Final recommendation by use case
- Everyday commuter replacing a damaged screen on a multi-voltage bike: M5 5PIN.
- Rider who wants vertical angle adjustability and several clamp sizes: UART 2 M6C.
- Conversion build looking for a color display: Bigstone C600E.
- Budget-conscious MTB owner with a compact handlebar: S866-SM.
