If you need an e-bike display that does more than show speed, the **Ebike UART No.
2 Color LCD Display** is aimed at practical control and daily ride information.
The big decision is compatibility: this is only for controllers that use **UART No.
2**.
Ebike UART No. 2 Color LCD Display Review Summary
The main reason to buy this **Ebike UART No.
2 Color LCD Display review** is simple: it bundles the usual speedometer and odometer functions with a broader control set, including cruise control, walk-assist mode, turn signals, voltage display, and configurable bike parameters.
That makes it a stronger fit for riders who want a more functional cockpit rather than a basic status screen.
It is especially relevant if you already know your bike uses the matching UART No.
2 protocol and you want a color display with USB charging built in.
If your controller is not compatible, this is the wrong purchase no matter how useful the feature list looks.

Key Features and Specifications of Ebike UART No. 2 Color LCD Display
The listing positions this as a color LCD e-bike display with a wide operating range and a feature set beyond simple trip data.
It is meant to work with 24V, 36V, 48V, and 60V battery systems, but the compatibility rule is more specific than the voltage range: the controller must use **UART No.
2**.
Key listed capabilities include:
- Color gradient screen for readable ride data
- Direction turn signals
- Walk-assist mode
- Cruise control
- Real-time trip and total mileage tracking
- Voltage display
- Parameter adjustment, including wheel diameter and speed limits
- USB charging port for on-the-go phone charging
- IPX65 waterproof rating
- ABS and PC housing, plus tempered glass screen and nylon bracket
That combination makes this more like a compact riding control center than a passive dashboard.
It is useful if you value information density and onboard convenience, not just a large speed readout.
The best way to think about it is as an upgrade for riders who want more visibility into battery status and more control over how the bike behaves.
The voltage display and mileage tracking are especially useful because they help with range awareness and ride logging without needing a separate device.
Pros and Cons of Ebike UART No. 2 Color LCD Display
Pros
- Broad feature set for a display unit, including cruise control, walk-assist, and turn signals
- USB charging port adds practical utility on longer rides
- Voltage display and mileage tracking support better ride planning
- Wide battery support across 24V, 36V, 48V, and 60V systems
- Weather-oriented build claims with IPX65 waterproofing and rugged materials
Cons
- Protocol compatibility is strict; only UART No. 2 controllers are supported
- The listing is heavy on features, so buyers need to verify wiring and controller match before ordering
- It is more specialized than a generic replacement display, which narrows the audience
For most buyers, the biggest pro is not the screen itself but the amount of control it exposes.
The biggest drawback is also obvious: if you are not already certain about the protocol, this is a risky buy.
Who Should Buy Ebike UART No. 2 Color LCD Display?
This **Ebike UART No.
2 Color LCD Display review** points to a very specific audience.
You should consider it if you are building, replacing, or upgrading an electric bike cockpit and you already know the controller uses UART No.
2.
It also makes sense if you want a display that can do more than show speed and battery status.
It should appeal to:
- Riders who want cruise control and walk-assist in the same interface
- Commuters who value battery voltage visibility
- Owners who want a USB charging port built into the dash
- Riders who need support for common 24V to 60V battery setups
- People replacing an existing compatible display and wanting more features without adding separate accessories
You should probably skip it if:
- You do not know your controller protocol
- You want a universal plug-and-play display
- Your main goal is only a very basic speed readout
- You are not interested in the extra controls or charging port
Bottom line: this is a good fit for informed buyers, not for anyone shopping casually.
Compatibility and Ride Controls
UART No. 2 Matters Most
The strongest and most important claim in the listing is also the first warning: this display is for **UART No.
2** controllers only.
That means the product is not defined by voltage alone.
A bike can be 36V or 48V and still be incompatible if the protocol does not match.
Parameter Adjustment
The ability to modify wheel diameter and speed limits is a meaningful feature for riders who want a display that reflects their setup accurately.
It is also useful when you need to fine-tune how the bike behaves after a replacement or upgrade.
Cruise and Walk Assist
Cruise control and walk-assist mode give the display more everyday value.
These are not flashy extras; they are practical controls that can make starts, slow maneuvering, and steady riding easier.
Display, Power, and Durability
Color Screen Readability
The listing emphasizes a vibrant color gradient screen, which suggests the product is trying to improve visibility and scan speed rather than just delivering raw data.
That matters because a display is only useful if you can understand it quickly while riding.
USB Charging Port
The built-in USB port is one of the more buyer-friendly details here.
If you use your phone for navigation or ride tracking, onboard charging can reduce battery anxiety on longer trips.
Outdoor Protection
The stated IPX65 waterproof rating and rugged mix of ABS, PC, tempered glass, and nylon bracket indicate a design aimed at weather exposure and vibration.
That does not make it indestructible, but it does signal a display intended for real riding conditions rather than sheltered indoor use.
Information Tracking and Battery Awareness
Trip and Total Mileage
Trip and total mileage tracking are standard on better e-bike displays, but they still matter because they help you understand how far you have ridden and how much use the bike has seen over time.
Voltage Display
Voltage reading is one of the most useful additions for battery-aware riders.
It gives you a more immediate sense of charge state than guesswork alone and can help you avoid getting stranded.
App Sync Claim
The listing mentions syncing with cycling apps to record routes and stats.
That is potentially useful, but buyers should treat it as a helpful feature claim rather than the main reason to purchase.
The core value is still the built-in display itself.
Alternatives to Ebike UART No. 2 Color LCD Display
If you need a different fit, start with options that are easier to match or more commonly used in e-bike builds.
These are not automatically better, but they are reasonable comparison points if you are checking whether your bike uses a different controller ecosystem or if you want a display line with broader community familiarity.
Is Ebike UART No. 2 Color LCD Display Worth It?
Yes, if your controller is confirmed to be UART No.
2 and you want a feature-rich display with real utility.
The combination of cruise control, walk-assist, voltage display, mileage tracking, and USB charging makes it a smart purchase for the right setup.
No, if you are uncertain about compatibility.
In that case, the risk of getting the wrong protocol support is too high to ignore.
**For informed buyers, it looks practical and well-targeted.
For everyone else, it is too specific to buy blindly.**
