Choosing between a standard 26-inch wheel and a fat-tire 20-inch wheel is the first big decision in any e-bike conversion project. Both of these rear hub kits run on 48V, come in black, and are listed as new, but they target different bikes and different performance levels. The listed prices sit USD 119.00 apart, and that gap signals a real difference in motor output and included features. The right pick comes down to the wheel size your bike can accept and how much power you actually need from your conversion.
Quick verdict: The 26-inch 1000W kit is the lower-priced route to electrifying a standard 26-inch bike. The 20-inch fat-tire 2000W kit costs more up front and brings substantially higher motor output to a fat-tire build.
| Product | Listed price | Price bar |
|---|---|---|
| 26" 48V 1000W Rear Wheel Kit | USD 185.07 | |
| 20" 48V Fat Tire 2000W Rear Wheel Kit | USD 304.07 |
The 26-inch 1000W kit wins if...
- You want the lower listed price in this pair.
- You're converting a 26-inch bike listed as compatible with an electric bike.
- You want after-sales service included in the kit.
- You're comfortable buying a separate 48V 17-20Ah battery.
The 20-inch fat tire 2000W kit wins if...
- You want 2000W instead of 1000W.
- You need a power-off brake handle that works with V-brakes or disc brakes.
- You want the higher listed efficiency of 83% or more.
- You prefer noise below 55dB.
26inch 48V 1000W E-bike Conversion Kit Rear Wheel Electric Bicycle Hub Motor Set
This kit is built around a 26-inch rear wheel and rated at 1000W, so it targets a standard electric-bike-style conversion. The motor is brushless and toothless, with a listed speed of 56km/h, and the package weighs 12.2kg (26.9lbs). It carries the lower price in this comparison. The main thing to budget for is the battery: the specification states 48V 17-20Ah lithium or lead-acid batteries are not included. That's the concrete trade-off for the lower starting point. If you already have a compatible 48V battery or plan to buy one, this kit gives you a clear path to a rear-wheel e-bike conversion.
20" 48V Fat Tire E-Bike Rear Wheel Hub Motor Electric Bike Conversion Kit 2000W
This kit steps up to 2000W through a 20-inch fat-tire rear wheel and is matched to an e-cross-style bike in the specs. It includes an LCD display and a PAS sensor, which makes it a more complete starting point for monitoring the ride. Assembly is required, and the brake handle is a power-off type that needs to pair with V-brakes or disc brakes. The price is the higher of the two in this comparison, so the bigger motor and the included display come at a larger up-front investment. If your frame accepts a fat-tire 20-inch wheel and you want the extra power, this is the kit to build around.
Final choice by use case
Pick the 26-inch 1000W kit when the bike you're converting uses a standard 26-inch rear wheel and you want to keep the conversion cost lower. Sourcing a separate 48V battery is the main extra step.
Pick the 20-inch fat-tire 2000W kit when your bike takes a 20-inch fat-tire rear wheel and you're ready for a physically bigger, higher-powered conversion with a display. Plan for the extra assembly work and the higher initial price.
