KT 36/48V 1000W Motor Controller with LCD3 Display for E-Bikes

The KT 36/48V 1000W motor controller with LCD3 display is a three-phase BLDC controller (motor controller) built on the KT (Kunteng) platform. It runs on either 36 V or 48 V battery systems and supports motors rated up to 1000 W. The maximum current is 22 A. Consequently, one part covers two of the most common e-bike voltages.

This kit fits electric bikes, electric scooters and other light electric vehicles. It works with three-phase brushless motors, including rear hub and front hub configurations. Moreover, the bundled LCD3 display mounts to the handlebar with the supplied bracket. Speed, mileage, battery voltage and assist level therefore stay visible in one place.

The controller suits two main scenarios. First, replacing a failed controller on an existing electric bike. Second, powering conversion kits and self-built projects that need 36 V or 48 V control up to 1000 W. In addition, it supports the PAS pedal assist system and an optional throttle.

Key Benefits

• Dual 36 V / 48 V voltage – the same controller works with both battery types, so an upgrade needs no new controller.
• Power up to 1000 W – this is the rated limit; peak values depend on your battery and motor.
• 3 / 5 / 9 assist levels – you choose how many assist steps appear while riding.
• LCD3 display with bracket – shows speed, mileage, battery voltage and the current assist level.
• PAS pedal assist system – delivers motor support while pedalling, with no throttle needed.
• KT standard protections – guards against overvoltage, undervoltage and overload conditions.
• Smooth start and modulation – power builds gradually, which helps in city traffic and off-road riding.
• Three-phase BLDC compatibility – suits rear hub motors, front hub motors and other BLDC layouts.

Who Is This For?

This KT controller with LCD3 display is aimed at electric bikes, electric scooters and other light electric platforms. It matches any vehicle running a three-phase brushless motor. Both rear hub and front hub builds are covered. The display connects to the controller using the KT protocol, so the pair works together out of the box.

Repair users form the first group. If the original controller on your 36 V or 48 V e-bike has failed, this unit restores drive and adds a fresh display. Builders form the second group. Conversion kits and scratch-built machines often need a controller that handles both voltages, and this one does.

Before ordering, confirm two details. Your system must be 36 V or 48 V. Your motor must be a three-phase BLDC type. Please also note the legal side: 1000 W exceeds the EU 250 W limit for pedal-assist bicycles. Such a vehicle is therefore treated as a moped under EU rules.

What Is in the Package?

• 1× KT motor controller (36/48 V, up to 1000 W, 22 A)
• 1× LCD3 display with handlebar bracket

PAS sensors, throttle grips, brake levers with sensors and other accessories are ordered separately.

Technical Specifications

Why Choose the KT 1000W Controller with LCD3?

The controller and display are sold as a matched pair. As a result, you avoid hunting for a separate screen that speaks the KT protocol. Wiring stays simple because both parts come from the same platform.

Tuning is the second reason. The LCD3 carries an open parameter menu with P, C and L settings. Wheel size, assist behaviour and throttle response can therefore be adjusted by the rider. You also pick 3, 5 or 9 assist levels, and the choice is stored rather than set on every ride.

Finally, one part serves two systems. The same unit drives both 36 V and 48 V packs. Riders who later move from a 36 V battery to a 48 V battery keep the controller they already own.

Frequently Asked Questions

Will this controller work on my 36 V electric bike?

• Yes, the unit supports both 36 V and 48 V battery systems.
• No setting change is needed when moving between the two voltages.

Which motors is it compatible with?

• Three-phase brushless (BLDC) motors.
• Rear hub motors, front hub motors and other BLDC configurations.

Does the LCD3 display come with a mounting bracket?

• Yes, the bracket is included and attaches to the handlebar.
• The screen shows speed, mileage, battery voltage and assist level.

Can I ride without a throttle?

• Yes, the PAS pedal assist system provides support while you pedal.
• A throttle grip is optional and ordered separately.

How many assist levels can I use?

• You can select 3, 5 or 9 assist modes.
• The chosen mode count stays saved between rides.

What protections does the controller have?

• Overvoltage, undervoltage and overload protection.
• These are the standard KT platform safeguards.

Is a 1000 W build street legal in the EU?

• 1000 W exceeds the EU 250 W pedal-assist bicycle limit.
• Such a vehicle is legally classed as a moped.

What is the maximum current draw?

• The controller is rated for a maximum of 22 A.
• Peak power depends on your battery and motor combination.

Whether you are reviving a tired e-bike or wiring a fresh conversion, this KT controller and LCD3 display arrive ready to work together. Check that your pack is 36 V or 48 V and that your motor is three-phase BLDC, then connect, mount the screen and set your assist levels.
