1000W 1500W 2000W Fat Tire E-Bike Conversion Kit with KT Controller & LCD3 / LCD8 Display

Product Overview

The 1000W 1500W 2000W Fat Tire E-Bike Conversion Kit is a high-torque, heavy-duty power upgrade engineered specifically for 20"x4.0", 24" x 4.0 and 26"x4.0" fat tire bicycles. Driven by an advanced KT (Kunteng) intelligent sine-wave controller, this system powers a robust direct-drive gearless rear hub motor to conquer deep snow, soft sand, mud, and steep off-road inclines. Engineered for wider 175mm or 190mm rear dropout fat bike frames, the kit reaches top speeds of 28–40+ mph (45–65 km/h) depending on wattage output. Paired with your choice of the classic blue backlit KT LCD3 display or the full-color KT LCD8 screen, riders get complete access to real-time telemetry, customizable P & C parameter tuning, 5-level Pedal Assist (PAS), and whisper-quiet motor control across all terrains.

Frequently Asked Questions (FAQ)

Q: Will this fat tire motor kit fit a standard 135mm bicycle frame?

A: No. Fat tire hub motors feature wider axle spacing designed specifically for fat bike frames with 175mm or 190mm rear dropout width. Please measure your rear frame dropout spacing before selecting your kit.

Q: Why is a KT (Kunteng) controller best for a high-power fat tire e-bike?

A: KT controllers deliver ultra-smooth sine-wave current control, keeping high-wattage fat tire motors whisper-quiet while providing complete P & C parameter customization via the LCD3 or LCD8 display for custom acceleration and speed profiles.

Q: What is the difference between the KT LCD3 and KT LCD8 displays?

A: Both displays offer full access to P and C setup parameters. The KT LCD3 uses a classic high-contrast blue backlit LCD screen, while the KT LCD8 features a vibrant full-color TFT display with graphic telemetry and superior sunlight readability.

Q: What battery specs are required for these fat tire kits?

A: We recommend pairing with a 48V to 72V Lithium-ion battery (15Ah to 20Ah+) equipped with a Battery Management System (BMS) rated for:

1000W Kit: Minimum 30A continuous BMS. We recommend you the Hailong battery;
1500W Kit: Minimum 35A to 40A continuous BMS. We would recommend you the down tube style or the triangle battery;
2000W Kit: Minimum 45A to 50A continuous BMS. We recommend you the downtube style battery and block shape battery.

How to measure wheel size and dropout of a bike

How to Measure a Bike Tire (How to Measure a Bicycle Tire)

In the bicycle field, the wheel size is the size of the bike wheel after you install the tire. So when you get the tire size, you get the bike wheel size.

If you have a bike tire on your wheel, you can generally find required measurement information on the tire wall (side of tire – see picture below).

Tire walls usually display the size as the picture below.

If you can’t find the sizing on the wall of your tire, here we show you the methods to get your bike wheel size.

The Standard Method (Easiest and Fastest Ways to Find Bike Tire Size)

The standard method is to measures the tire width and tire diameter in inches.

How to Measure Bike Wheel Size with the Standard Method

Put your bicycle on its kickstand or against a wall so that it’s stable.
Place the bottom of the tape at the lowest point of the tire (on the ground) and measure in a straight line to the centre of the bike wheel to find your wheel radius (as shown in the image above). Multiply your wheel's radius by two, then it is the wheel's diameter. it is the wheel size.
Measure the tire's width by placing the type across the top of it like the picture below. the number you got is the tire width. Be sure to list the diameter first, followed by the tire width.
Bike wheel diameters are rounded to the nearest half-inch, so if your measurements are just over or under, round up or down to the nearest size.

How To Measure a Bike Wheel (Rim) for Tire Size

If you do not have your bike’s tire to hand, you can determine the tire size by measuring your bike’s rim width in millimetres as well.

Based on the average tire and wheel combinations currently on the market, the following charts illustrate the coinciding tire size and rim length.

Many rims will display their size somewhere, but some rims may be missing this measurement.

If you cant find measurement on your wheel’s rim, follow the easy steps below that will help you determine the appropriate tire sizes your rim can handle.

With no tire on your bike wheel, position the wheel vertically and hold it steady.
Take a measuring tape and press it against the inside of the rim, where the tire bead would normally sit.
Measure the internal distance from one side of the rim to the other (as shown in the image above).
Take this width and apply it to the correct table below.

Road Bike Rim Width to Tire Size Chart

Mountain Bike Rim Width to Tire Size Chart

Measure of Wheel

20" -- outer tire: 495mm dia.; rim: 410mm dia.;

24" -- outer tire: 600mm dia.; rim: 517mm dia.

26" -- outer tire: 650mm dia.; rim: 573mm dia.;

700C -- outer tire: 690mm dia.; rim: 635mm dia.

28" -- outer tire: 710mm dia.; rim: 650mm dia.

How to measure the dropout of your bike

The dropout of your bike is important, it can decides if the electric bike kit can fit your bike or not. So before your purchase of an ebike kit, please measure the dropout of your bike first.

Bike dropout is literally called frame spacing, is the inside distance between the two fork ends (drop outs) where the wheel fits in. it is very easy to be measure just by removing the wheel and holding a ruler to measure the place where the wheel came out. please check the following picture.
