When you're shopping for e-bike motors, controllers, and displays, the first question is scope. Do you just need a new screen to replace a dead display, or do you want to add a motor to a bike that doesn't have one? The four options here answer that in very different ways.
Quick take
If your bike already has a working controller and you simply want a readable screen, the S866 is the leanest buy. If you want a more informative screen, the Bigstone C600E is the more complete display option. If you want to add a motor to a bike, the full motor kit is the all-in-one route.
Price comparison
| Option | Listed Price | Price Bar | Best For |
|---|---|---|---|
| UART 2 M6C LCD Display Meter | $38.99 | Replacing a display on an existing e-bike | |
| Bigstone C600E Display Kit | $75.99 | Riders who want a 3.5-inch TFT screen | |
| S866 E-Bike LCD Display | $23.99 | A low-price display for e-bike upgrades | |
| 26-inch 1500W Front Wheel Conversion Kit | $261.69 | Adding a motor to a compatible bike |
Decision matrix
- Need a simple screen replacement? Choose the M6C if you want vertical screen tilt and multiple handlebar sizes, or the S866 if you want the lowest price.
- Want a color display with speed, current, distance, and error codes? The Bigstone C600E is the one to consider.
- Want motor power, not just a new screen? The conversion kit is the one that turns a bike into an e-bike.
Product notes
UART 2 M6C LCD Display Meter
The M6C display is a direct replacement choice when your e-bike already uses UART2 communication. For $38.99 you get a 98.1mm x 61.9mm x 24.6mm LCD panel with three color zones to distinguish the display areas, and the screen angle can be adjusted vertically for better visibility. It covers the usual ride information and lets you switch between miles and kilometers. The holder fits 22.2mm, 25.4mm, 28.6mm, and 31mm handlebars, so you have some flexibility. The limitation is protocol matching: if your controller does not speak UART2, this display may not work properly.
Bigstone C600E Display Kit
The Bigstone C600E display kit is the color option here. It uses a 3.5-inch TFT screen with 320x480 resolution and is rated for 24V/36V/48V systems, making it useful for a range of e-bike builds. The display shows speed, current, driving mode, distance, travel time, and error codes, with KM/H & MPH switching. A backlight indicator and 6km/h walk function add some everyday convenience. At $75.99 it sits between the low-price display and the full kit. The main catch is protocol compatibility: different e-bike brands use different LCD display protocols, so the C600E may need to be matched to your controller. Confirm that before buying, or it may not communicate with your system.
S866 E-Bike LCD Display
The S866 is the lowest-price option at $23.99. It packs battery indicator, headlight control, PAS levels, trip/total mileage, riding time, fault indicator, walking mode, and error warnings into a small 80.5mm x 47.5mm x 9.2mm weather-resistant unit. The display uses UART2 communication, so it suits a bike that already has a UART2-compatible controller. The compact clamp fits 22.2mm handlebars. If you want an inexpensive screen for a mountain bike build that already has the motor and controller sorted, this is the display to grab. The tradeoff is that it is a display only, and it is built around a fixed 22.2mm clamp.
26-inch 1500W Front Wheel Conversion Kit
The 26-inch front-wheel conversion kit bundles the motor, display, and throttle together. For $261.69 you get a 1500W hub motor, a PAS sensor, an LCD display, a thumb throttle, and brake levers that cut motor power when applied. The motor spins at 520r/min, which gives steady startup and acceleration, and the VA LCD shows gear, speed, and mileage at a glance. It's a 48V lithium-ion system with disc brakes, so it covers more of the conversion in one purchase than the standalone displays. The catch is scale: this is a front-wheel installation, not a plug-in display, and it is designed for a compatible bike. If you're ready for a larger project, this one is the route to take.
Final recommendation
For a quick screen replacement, the S866 is the low-price pick, while the M6C costs a bit more and adds display flexibility. If you want a color display with more ride data, the Bigstone C600E is the choice. If you want to electrify a bike, the conversion kit is the one in this group that comes with the display and throttle in one package.
