7 Best Electric Bike Controllers With LCD Display for E-Bike Upgrades (2026)

A 5-pin LCD ebike display for UART No. 2 protocol systems, showing speed, battery, mileage, PAS level, and voltage on 24V to 64V setups.

Pros

• +Five-pin UART No. 2 wiring for compatible controllers
• +Voltage setting spans 24V, 36V, 48V, 60V, and 64V systems
• +Toughened glass screen over the LCD panel
• +Four handlebar ring sizes cover common bar diameters

Cons

• −Won't work if the controller runs a different protocol
• −No warranty term stated in the listing
• −Display only, no controller or wiring harness included

The first thing I'd check on this GLOBELEC display is the connector, not the screen. It runs the UART No. 2 protocol over a 5-pin plug, so it only talks to controllers wired the same way. A mismatched protocol means no speed, no battery readout, nothing.

Once that lines up, the spec sheet is sensible for a bar-mounted unit. The voltage setting covers 24V through 64V, and the four ring sizes span 22.2mm to 31.8mm bars, so it fits most commuter, hybrid, and e-scooter setups without shims. The shell is reinforced ABS+PC with an aluminum bracket and toughened glass over the panel.

The listing rates it IP65, which covers rain splash and road spray but not submersion. Worth knowing before you buy: no warranty term appears anywhere in the listing. I'd consider this a reasonable replacement for a cracked or dead display on a compatible bike.

A brushless motor controller kit rated for 24V, 36V, and 48V systems at 500W and 25A, paired with a multifunction LCD display and 22mm handlebar bracket.

Pros

• +Three voltage options reduce guesswork when matching an existing battery
• +LCD panel reports speed, battery level, ride time, and trip distance
• +22mm bracket fits standard handlebars on most e-bikes and scooters
• +Labeled connectors simplify matching the harness to each port

Cons

• −No motor wattage ceiling or phase current spec disclosed
• −Display waterproofing described only as waterproof, no IP rating given
• −Controller enclosure dimensions and mounting pattern not listed

The 1PZ controller kit covers the three voltage systems most home builders actually run: 24V, 36V, and 48V, with a 500W output and 25A current rating. That spread matters because swapping a battery pack usually forces a controller swap too, and this one sidesteps that on common hub and mid-drive setups.

The included LCD is the part I would weigh most. It shows speed, battery level, ride time, total mileage, and trip distance, with a backlight for low-light riding and a bracket sized for 22mm handlebars. Labeled connectors mean the harness plugs in port by port rather than by guesswork.

Worth knowing before you buy: the listing names brake power-off, undervoltage, and overcurrent protection but gives no motor wattage ceiling, no phase current figure, and no IP rating for the display. I would treat this as a solid pick for a straightforward e-bike or scooter build where the existing motor and battery specs are already known.

ChongXiao WXGN301 brushless controller with LCD display, compatible with 36V to 72V systems and up to 1000W motors.

Pros

• +Four voltage options cover common e-bike and e-scooter builds
• +LCD panel displays speed, battery, mileage, and fault codes
• +Aluminum alloy shell aids heat dissipation on long climbs
• +App-based parameter tuning for personalized riding settings

Cons

• −No wiring harness or connectors listed as included
• −App required for parameter changes, no on-device tuning
• −No waterproof or IP rating stated for wet-weather riding

The ChongXiao WXGN301 stands out for one reason: it works across 36V, 48V, 60V, and 72V battery systems and supports motors up to 1000W. That range means you can move it between a 48V commuter and a 72V build without buying a second controller. The LCD panel shows speed, battery level, mileage, and fault codes, which helps when diagnosing a cutout on the side of a ride.

I rate the aluminum alloy heat dissipation shell as the practical detail here. Controllers that drive 1000W motors build heat on long climbs, and the alloy housing gives that heat somewhere to go. The listing also names overvoltage, undervoltage, overheating, short circuit, and anti-runaway protections, though I would not treat any of those as a substitute for a correctly matched battery and motor.

Worth knowing before you buy: the listing does not name a wiring harness, connectors, or a waterproof rating. If your build sees rain or you need plug-and-play wiring, factor that in. I see this working best for someone building or repairing a mid to high power e-bike who is comfortable with wiring and app-based tuning.

A 24V/36V/48V 350W brushless controller and LCD display kit for ebikes and scooters, with a 17A controller and 22mm handlebar mount.

Pros

• +Multi-voltage support covers 24V, 36V, and 48V systems
• +LCD tracks speed, battery, ride time, and mileage
• +Brake power-off and overcurrent protection built in
• +Labeled wiring harness eases controller replacement

Cons

• −No IP rating stated for controller or display
• −Mounting bracket limited to 22mm handlebar diameter
• −No wiring diagram included beyond cable labels

The CSBST 350W brushless controller kit pairs a 17A controller with an LCD display that reads real-time speed, battery power, and both trip and total mileage. I see this as a practical replacement for a failed controller on a 24V, 36V, or 48V ebike or scooter, especially since the harness carries cable instruction labels rather than requiring a wiring diagram.

The controller measures 85 mm by 53 mm by 30 mm, so it fits the usual frame-mount space on a hub-motor build. Its brake power-off and undervoltage protection are worth having on a commuter or DIY project where a drained pack or stuck brake lever can otherwise leave you pushing home.

Worth knowing before you buy: the listing gives no IP rating for the controller or display, and the display bracket only fits 22mm handlebars. I'd consider this a reasonable pick for a dry-weather commuter or a garage build, not a bike left outside in steady rain.

A 500W brushless motor controller kit with LCD display and thumb throttle, weighing about 0.95 pounds, for 24V, 36V, and 48V ebike or scooter builds.

Pros

• +500W controller supports 24V, 36V, and 48V systems
• +LCD display provides speed, battery, and mileage data
• +Labeled wiring simplifies installation on compatible bikes
• +Thumb throttle designed for smooth, comfortable acceleration

Cons

• −No waterproof rating stated for controller or display
• −No warranty term disclosed in the listing
• −Compatibility limited to hall-effect motors and 22mm handlebars

The CSBST 500W brushless controller kit bundles a motor controller, LCD display, and thumb throttle into one package for 24V, 36V, or 48V ebike and scooter builds. At 0.95 pounds, it adds little weight, and the labeled wiring harness takes some guesswork out of matching controller ports to the motor, display, and throttle.

The LCD shows real-time speed, battery power, riding time, and trip mileage, which I'd consider useful for tracking range on longer commutes or errands. The thumb throttle has concave dots for grip, and the included bracket fits 22mm handlebars, a common size on many ebikes.

Worth knowing before you buy: the listing names undervoltage and overcurrent protection but no waterproof rating for the controller or display, and no warranty term is stated. I see this working best for riders upgrading a compatible hall-effect motor setup who can keep the electronics out of heavy rain.

45A sine wave controller for 1600W-2300W ebikes, paired with a CS866 color LCD that supports 24V-52V systems.

Pros

• +Sine wave output compatible with both Hall and Hall-free motors
• +Self-learning function simplifies phase and rotation matching
• +CS866 display supports four common ebike voltages
• +Display shows speed, battery, and two mileage readouts

Cons

• −Light switch requires an external button unless using the display
• −No wattage or amperage rating disclosed for the included throttle
• −Voltage must be set manually via P03 parameter before riding

The JOCHEN 45A sine wave controller is built around a 1600W to 2300W power window, which puts it in the range of heavier hub-drive builds rather than commuter conversions. The self-learning white line handles phase angle and rotation direction automatically, so matching a replacement controller to an existing motor is less of a guess.

The CS866 color LCD covers 24V, 36V, 48V, and 52V systems, with voltage selected through the P03 parameter. It reports speed, remaining charge, subtotal mileage, and total mileage, which is enough to track a commute or a long gravel loop without a separate computer.

Worth knowing before you buy: the red and black lamp cable only supplies battery voltage, so turning lights on and off needs a switch unless you wire through the display and hold the up button for three seconds. I see this working best for riders replacing a failed controller on a mid-power hub-drive setup.

All-in-one e-bike controller kit with LCD display, throttle, and 1T5 cable. Supports 24V, 36V, and 48V systems at 250W or 350W.

Pros

• +Complete kit with controller, display, throttle, and cable
• +Backlit LCD readable in low light or night rides
• +Waterproof connectors for wet-weather riding
• +Works across 24V, 36V, and 48V at 250W or 350W

Cons

• −Fits only standard 2mm handlebars per listing
• −No specific waterproof rating or warranty stated
• −Controller dimensions may limit mounting options

The Oceanialend brushless motor controller kit bundles the parts needed for an e-bike upgrade or repair: a controller, LCD display, 1T5 cable, and throttle. The backlit LCD stays readable on night rides or dim commutes, and the waterproof connectors mean I would not worry about splashes on a wet shoulder-season ride.

It works across 24V, 36V, and 48V systems at 250W or 350W, so it suits a range of motor setups rather than one fixed voltage. At about 1.1 pounds, it adds little to the bike.

Worth knowing before you buy: the listing specifies a fit for standard 2mm handlebars, so check your bar diameter first. I see this as a practical spare or upgrade kit for riders running those motor and voltage combinations.
