Fat Tire E-Bike Tires and Wheels: Five Listings Compared by Size, Material and Pack Count
As an Amazon Associate we earn from qualifying purchases.
Fat tire e-bikes use wide tires on a 20-inch or 16-inch rim, and the replacement parts for them are sold by size, pack and inner tube. The listings in this group include a complete 20-inch rear wheel with a motor, a wheel upgrade kit, and several tire sets in 20 by 4 inches. Tire size is the first detail to match, and the count tells you how many tires or tubes you receive. This guide reads each listing by the size, material and included parts it states.
Quick answer
Start with the rim size. Most listings here are for a 20-inch wheel, and the tire is usually 20 by 4 inches, though one option is 20 by 3 inches. The Ultraverse listing covers 16, 20, 24 and 26-inch tires, so check the exact size on the product page. Then check the count, since some listings are a single tire and others are a pair or a set with tubes and levers. Material is rubber in most of the tire listings.
How we chose
Each entry uses the product details saved for the listing: the wheel size, tire size, material, color, number of items, unit count and included components. The guide reports these as the listing gives them. It does not describe how any tire grips loose ground, how long it lasts, or how it rolls on a particular bike. It does not rank the tires against each other.
What we could not verify
Ride quality and puncture resistance are not measured here. Several listings give the tire size in more than one place, and the figures are not always the same, so the guide notes those differences. Compatibility with a specific bike is not confirmed. Where a listing does not say whether tubes are included, the guide leaves it out.
The five listings
KPATH: 20 by 4 inch rear wheel with 48V 1000W motor, aluminum
The KPATH listing is a complete rear wheel for an electric bicycle. It is 20 inches across and sized 20 by 4 inches, with an aluminum rim and a rear-wheel motor included. The item weight is 10.5 pounds, and the color is listed as black. The listing describes the motor as 48 volts and 1000 watts. Because a motor wheel is a complete part, check the axle and the hub spacing against your frame before ordering. View the KPATH rear wheel on Amazon.
Woozis: 20 by 4 inch mag wheel upgrade kit, front and rear
The Woozis listing is a wheel upgrade kit for fat tire electric bikes in 20 by 4 inches, with a front wheel hub included. The color is listed as black. The title describes a front and rear wheel set, but the components field names only the front wheel hub, so check what you receive before ordering. A kit like this replaces the rim and hub rather than the tire alone. View the Woozis wheel kit on Amazon.
SIMEIQI: 20 by 4 inch folding bead tires, two bike tires, pack of four
The SIMEIQI listing is a 20-inch fat tire in black rubber, sold as two bike tires within a unit count of four. The title describes a folding bead, which the listing calls heavy duty. The number of items is two, and the components field names two tires. Confirm whether the unit count includes tubes, since the listing does not name tubes in the components field. View the SIMEIQI tires on Amazon.
kulifoo: pack of two, 20 by 4.0 inch tires with tubes and tire levers
The kulifoo pack is two 20 by 4.0 inch rubber tires in black, with two inner tubes and two tire levers. The unit count is two and the listing names every component in its components field, which makes it the most complete tire set in the group. The tire lever is useful when a tire is changed on the road. View the kulifoo tire set on Amazon.
Ultraverse: 16, 20, 24 and 26 by 4.0 inch fat tires, pack of two
The Ultraverse listing is a pair of fat tires in black with a yellow logo, sized in the title as 16, 20, 24 and 26 by 4.0 inches. The size field gives 16 by 4.0 and the wheel size field gives 16 inches, so the listing’s sizes do not agree. Check the exact size on the product page before ordering, since the fitment depends on the rim. The unit count is two. View the Ultraverse tires on Amazon.
A comparison by size and pack
| Listing | Type | Size as listed | Material | Count |
|---|---|---|---|---|
| KPATH | Complete rear wheel with motor | 20 × 4 in | Aluminum rim | 1 |
| Woozis | Wheel upgrade kit | 20 in | Not stated | 1 hub |
| SIMEIQI | Folding fat tires | 20 × 4 in | Rubber | 2 tires |
| kulifoo | Tires with tubes and levers | 20 × 4.0 in | Rubber | 2 |
| Ultraverse | Fat tires, multiple sizes | 16 × 4.0 in (size field) | Rubber | 2 |
Rim size and count are the two columns to compare first. The Ultraverse listing gives more than one size, so check its size before choosing it.
Rim and tire size
The number before the x is the tire width, and the number after it is the rim diameter. A 20 by 4 inch tire fits a 20-inch rim, while a 16-inch Ultraverse tire fits a 16-inch rim only. Measure the rim or check the existing tire before ordering.
What is in the box
The kulifoo pack includes tubes and tire levers. The SIMEIQI and Ultraverse listings name tires only in the components field. The KPATH wheel includes the motor, and the Woozis kit includes a hub. Check the box contents before assuming you need extra parts.
Checks to make before you order
Confirm the rim diameter and the tire width on your bike.
Check the count and what is included, since some listings name tires only.
For the KPATH and Woozis wheels, check the axle and hub spacing against your frame.
Which listing suits which fix
For a replacement tire with its own tubes and tools, the kulifoo pair is the most complete option. For a complete rear wheel with a motor, the KPATH listing is the match. For a wheel upgrade on the front, the Woozis kit is the one to compare. For a pair of tires in several sizes, check the Ultraverse size page carefully.
Tube and tool details
The kulifoo pack names two inner tubes and two tire levers with the two tires, which covers a roadside change for both wheels. The SUNDAWN listing names a rim strip, a valve core wrench, two tire levers and two valve cores along with its tire and tube. The SIMEIQI and Ultraverse listings name tires only, so plan to buy tubes and levers separately if you need them.
Frequently asked questions
Do I need tubes with new tires?
The kulifoo pack includes tubes. The other tire listings name tires only, so check the components field before ordering.
What does the 4.0 in the size mean?
It is the tire width in inches. The 20 is the rim diameter, so a 20 by 4.0 tire fits a 20-inch rim.
Can I use a fat tire on any e-bike?
Not always. Check the rim size, the tire width and the clearance in the frame and fork.
