26Inch 48V 1000W Rear Hub Motor Kit for Bicycle E-Bike Retrofit Upgrade
Choose this kit if you have a 26-inch bike and want a 48V 1000W rear hub without spending more than necessary. The listed details include a brushless and toothless motor, efficiency above 80 percent, and a speed of 56 km/h, which matches a commuter-style riding pace. It uses aluminum, iron, copper, magnetic steel, aluminum alloy, and rubber butyl materials, and the motor shaft length is listed at 20 cm. Keep in mind that the battery is not included; the listing says it accepts 48V 17-20Ah lithium or lead-acid batteries. The kit is described as a retrofit upgrade, so it is aimed at riders who already have a compatible bike and want to add electric power.
72V 3000W Ebike Bicycle Conversion Kit4.0 Rear Hub Motor Wheel Fat Tire 20 24 26
Go with this kit when power and tire flexibility take priority. It's the only one of the four listed with a 3000W motor and a 72V system, and the title says the rear hub wheel fits fat tires in 20, 24, and 26 inch sizes. The listed attributes also include support for universal and multiple e-bike styles like e-cargo, e-city, e-mountain, and e-folding bikes, plus a 170mm rear wheel spacing. It comes with an LCD M9 set and a two-year manufacturer warranty. Before choosing it, consider the note in the description: with a 72V 3000W motor, the maximum current when the battery is fully charged should stay below 50A, and the recommended approach is to use power-assisted mode on uphill climbs rather than pure electric mode.
26inch 48V 1000W E-bike Conversion Kit Rear Wheel Electric Bicycle Hub Motor Set
This is the sibling of the first kit in both price and core specs: USD 183.18, 48V, 1000W, and a 26-inch rear wheel. The listing also says the motor runs with high efficiency and uses a brushless, gearless design. What sets it apart in the supplied details is the explicit after-sales service note and the gross weight of 12.2kg / 26.9lbs, which gives you a sense of the physical kit weight. As with the other 48V 1000W option, the battery is not included, and it is designed for 48V 17-20Ah lithium or lead-acid batteries. If you're picking between this and the other 26-inch kit, the main difference in the listings is the after-sales service wording rather than the motor itself.
20in Rear Wheel 48V 1500W Electric Bicycle Ebike Conversion Kit Hub Motor LCD
Choose this kit if your bike uses a 20-inch rear wheel and you want more power than the 1000W options without stepping up to 72V. The listed price is USD 298.32, and the motor is rated at 48V and 1500W with an efficiency above 82 percent, according to the product description. The kit also includes an LCD display, a 48V 1500W controller, and a power-off brake lever, and assembly is required. The battery is not included, with the listing specifying a 48V 20A lithium battery. This setup is best suited to a smaller wheel size, and the listed PAS sensor is designed to make pedaling and climbing easier.
Final Recommendation
For most 26-inch commuter-style bikes, either 48V 1000W kit at USD 183.18 gives you rear-hub power without a battery purchase included. If you prefer an LCD display and a compact wheel, the 20-inch 48V 1500W kit at USD 298.32 is the middle option. For a fat-tire build where 3000W and 72V matter more than price, the USD 695.74 72V 3000W kit is the one that matches that ambition.
