Choosing an ebike rear hub means settling two questions before you spend: what voltage and power you need, and how much of the conversion system you want in the box. The options here range from a standalone rear wheel to a full conversion kit, so the right pick depends on your bike's wheel size, your existing battery, and whether you already own a controller and throttle.
Quick take
Need a direct answer? If you already have a battery and the rest of the electronics sorted, a standalone hub motor covers the basics. If you want more of the system in one box, a bundled conversion kit does more of the work. If you are building a high-voltage bike, the top-power kit is the only one here that reaches that level.

US 1500W 48V Hub Motor Rear Wheel for Electric Bicycle E-bike Kit 7 Speed

The SENDERPICK motor pairs a 48V 1500W brushless gearless rear hub with a 7-speed freewheel, a 17mm axle, and 135-145mm dropout compatibility, which makes it a practical swap for many rear frames. At USD 135.53 it sits between the lowest-price motor and the more complete kits. The 243mm motor diameter, three hall sensors, 500RPM rated speed, and 40N·m torque are the mechanical specs that matter for a 1500W build. The 6-hole disc brake support means you can run a disc rotor on the same wheel. The limitation is the package: it contains the hub motor, so a controller, display, battery, and throttle are not included.
20in Rear Wheel 48V 1500W Electric Bicycle Ebike Conversion Kit Hub Motor LCD

For a 20-inch wheel build, this is the more complete route. It includes the rear hub motor, a 48V 1500W controller, an LCD display, and power-off brake levers, and the 48V 20A lithium battery is not included, so that part is still on your shopping list. The motor is brushless and toothless, rated at 500RPM with efficiency of at least 82%, and the wheel has an M14 motor shaft. At USD 290.00 it is the higher-priced 48V option in this comparison, but you avoid sourcing a display and brake levers separately. The real limitation is wheel size: a 20-inch rear wheel only fits bikes built around 20-inch wheels.
For Electric Bicycle E-bike Rear Wheel & Parts 48V 1500W Hub Motor

At USD 108.91, this is the lowest-price 48V 1500W rear hub in the group. It uses a brushless gearless threaded design with three hall sensors, a 17mm axle, an M14 shaft, and a 135-145mm hub opening, matching the SENDERPICK motor's dropout fit. The 7-speed flywheel is included, and the wheel has a 6-hole disc brake mount, though the brake rotor is not included. If you already have the controller, display, and battery sorted, this rear-wheel-and-parts hub motor is a direct way to get a 1500W rear wheel without paying for extras you do not need.
72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W

This is the only option here that crosses from 48V to 72V, and it comes as a package rather than a bare wheel. The 27.5-inch aluminum wheel carries a 2000W motor rated at 560RPM and 60N·m of torque, the highest output numbers in this comparison. The kit also includes a 9-speed flywheel, LCD display, controller, throttle, pedal-assist sensor, power-off brake levers, controller bag, and an English manual. At USD 309.52 it is the most expensive choice, and the 72V battery is not included. It makes sense for a 27.5-inch bike with a 72V battery behind it.
Final recommendation by use case
Choose the Rear Wheel & Parts hub motor if you want to spend the least and already have the supporting electrics. Choose the 20in kit if you are working with a small wheel and want more parts included. Choose the US hub motor if you want a middle-priced motor-only rear wheel. Choose the E-Bike Motor conversion kit if you want the highest power output and a full accessory package.
