A 2000W rear hub motor on a 20-inch fat tire wheel. That is a lot of power in a small package. The LTIGOAW 20-inch 48V 2000W conversion kit on Amazon targets the high power end of the hub motor market with a complete rear wheel package built for fat tire bikes. 65 Nm of torque, an LCD display, and a claimed top speed of 34 mph. Let us dig into what this kit actually delivers.
Specs and Build Quality
The LTIGOAW kit uses a brushless gearless direct drive hub motor. 2000 watts continuous is serious power for a hub motor. That puts it in the same territory as the big Voilamart and Ebikeling 2000W kits but on a 20-inch fat tire wheel instead of a standard 26-inch.
The 20x4 inch fat tire format is the key differentiator. Fat tire bikes have become hugely popular for snow, sand, and off-road riding. A 2000W motor on a 20-inch wheel gives you massive torque at the rim thanks to the mechanical advantage of the smaller diameter. The motor does not have to work as hard to accelerate a 20-inch wheel compared to a 26-inch or 700C wheel.
Torque is rated at 65 Nm. That is a solid number for a direct drive hub. Geared hub motors often produce more torque at lower speeds, but 65 Nm from a direct drive unit is respectable. The motor should pull hard from a stop and maintain speed well on moderate hills.
Claimed top speed is up to 55 km/h, which is about 34 mph. That is fast for an ebike. Real world speed depends on battery voltage, rider weight, and terrain. A fully charged 48V battery will give you more speed than one at 30 percent charge. Expect the mid to high 20s in practical riding conditions with a typical rider.
Noise is rated at under 55 dB. That is quiet. Direct drive motors are inherently quieter than geared hubs because there are no planetary gears to whine. The LTIGOAW motor should be barely audible over tire noise and wind at speed.
Efficiency is listed at 83 percent or higher. That is typical for a direct drive hub motor. Geared hubs can hit higher efficiency numbers, but direct drive units make up for it with simplicity and durability. No gears means nothing to strip or wear out.
The motor casing is aluminum alloy with a baking paint finish. The paint looks durable in the product images. The axle has machined flats for torque arm mounting. At 2000 watts, torque arms are absolutely mandatory. The axle will try to spin in the dropouts under hard throttle. Do not skip this.
Installation and Compatibility
Rear wheel hub motor installation is more involved than front wheel. You have to deal with the drivetrain, derailleur, and freewheel. The LTIGOAW kit is designed for 20-inch fat tire bikes, which narrows the compatibility window significantly.
Compatibility checklist:
The wheel is 20 inches with a 4-inch wide fat tire. That only fits frames designed for 20x4 fat tires. Think electric fat tire folders like the Lectric XP, RadExpand, and similar models. Also fits custom fat tire builds, trikes, and some cargo bikes. It does not fit standard 26-inch mountain bikes, 700C road bikes, or narrow tire 20-inch folding bikes.
Frame dropout spacing is another concern. Fat tire bike frames typically have wider rear dropouts to accommodate the wider hub and tire. Measure your dropout spacing before ordering. The LTIGOAW motor axle needs to fit your frame.
Installation steps:
- Remove the existing rear wheel and tire
- Install torque arms on both dropout sides
- Mount the LTIGOAW wheel and tighten the axle nuts
- Mount the controller to the frame
- Route the motor cable along the chainstay
- Connect the LCD display, thumb throttle, and brake levers
- Connect the battery and test the system
The kit includes power-off brake handles compatible with both V-brakes and disc brakes. That is a nice touch. Many budget kits only support one brake type. The LTIGOAW levers work with either, so you do not need to swap your existing brake system.
The thumb throttle is included. Thumb throttles are more comfortable than twist throttles for off-road riding where you want to maintain a firm grip on the handlebar. They also take up less space on the bar.
The LCD display shows speed, battery level, trip distance, odometer, and PAS level. The display is backlit for night riding. The readout should be readable in most lighting conditions based on the product images.
The controller is a separate unit that needs frame mounting. The wiring is plug and play with color coded connectors. No soldering required. Budget about two to three hours for a first time installation.
What Amazon Reviewers Are Saying
The LTIGOAW kit has 9 reviews on Amazon with a 4.1 out of 5 star average. That is a decent sample size for a relatively new kit. The overall rating is solid.
Positive reviews highlight the power and acceleration. Riders report strong hill climbing ability and good top speed. The fat tire compatibility is a common positive point. Builders who installed this on Lectric XP and similar folding fat tire bikes report good fit and performance.
Negative feedback mentions the controller mounting bracket and some wiring routing challenges. A few reviewers note that the instructions could be clearer. That is common with budget conversion kits. The instructions are usually a photocopied sheet with basic diagrams. Nothing unusual there.
The 4.1 star average from 9 reviews is encouraging. No major red flags in the feedback. The kit seems to deliver on its power claims based on what buyers are saying.
Who Is This Kit For?
This kit is for the fat tire bike owner who wants serious power. If you have a 20-inch fat tire folding bike and you want to turn it into a 2000W beast, this is one of the few kits that fits that specific niche. The combination of 2000W power, 65 Nm torque, and 20-inch wheel size is hard to find in a single package.
It is also a good option for custom fat tire builds. If you are building a fat tire trike, cargo bike, or off-road machine from scratch, the LTIGOAW kit gives you a complete rear wheel solution with the motor pre-laced into the rim. No wheel building required.
Who should skip it:
Riders with standard 26-inch or 700C bikes cannot use this kit. The 20-inch fat tire wheel is not compatible with standard frame sizes. If you have a regular mountain bike or road bike, look at 26-inch or 700C hub kits instead.
Riders who want a stealthy or lightweight conversion should look elsewhere. A 2000W direct drive hub motor is heavy. The motor, wheel, and tire combination adds significant weight to the rear of the bike. The bike will feel rear heavy.
And riders who do not need 2000W of power may be better served by a 1000W or 1500W kit. More power means more battery consumption. You will need a high capacity 48V battery to get reasonable range from a 2000W motor.

Frequently Asked Questions
Does the LTIGOAW kit include a battery?
No. You need a separate 48V ebike battery. A 2000W motor draws significant current, so choose a battery with a high discharge rating. Look for at least a 30A BMS. Budget 200 to 350 dollars for a quality battery that can feed this motor properly.
What bikes does a 20x4 fat tire wheel fit?
Folding fat tire bikes like the Lectric XP, RadExpand, and similar models. Also fits custom fat tire builds, trikes, and cargo bikes designed for 20x4 tires. Does not fit standard 26-inch, 27.5-inch, or 700C frames. Measure your dropout spacing before ordering.
What is the real world top speed?
The manufacturer claims 34 mph. Real world speed depends on rider weight, battery voltage, and terrain. Expect the mid to high 20s with a typical rider and a standard 48V battery. A higher voltage battery like 52V would push the top end higher.
How much torque does the motor produce?
65 Nm. That is strong for a direct drive hub motor. The 20-inch wheel multiplies the effective torque at the rim, so acceleration feels punchier than the raw number suggests. The motor should handle moderate hills without issue.
Do I need torque arms for a 2000W motor?
Absolutely. A 2000W hub motor generates enormous torque. The axle will try to spin inside the dropouts under hard throttle. Install heavy duty torque arms on both sides of the rear dropouts. Do not skip this step. Frame damage is expensive.
Is the motor weather resistant?
The motor casing uses gaskets and sealed bearings. It should handle rain and wet roads. Avoid pressure washers and deep puddles. The controller is the more vulnerable component. Mount it in a location that is protected from direct water spray.
