Choosing an ebike conversion kit often boils down to two questions: what wheel does your bike already have, and how much power do you want to add? These two hub motor kits sit at opposite ends of the spectrum. The 1000W kit is listed at USD 147.57, while the 2000W kit is listed at USD 309.52, a gap of USD 161.95.
Quick verdict
If you want a high-voltage, high-power rear wheel build, the 72V 2000W kit is the more substantial option on paper. If you prefer a lower-priced motor with mounting flexibility, the 1000W 48V kit is the more practical choice.

Where each kit wins
The higher-voltage rear wheel kit brings a larger wheel, the higher listed torque and rotational speed, along with a display and full control set. The lower-priced front/rear hub kit brings a lighter front wheel, hub widths for 100mm front or 135mm rear, and a tire and tube included.
72V 2000W Rear Wheel Kit
This kit pairs a larger aluminum rear wheel with a 9-speed flywheel, LCD display, ordinary throttle, pedal assist sensor, and power-off brake lever. The listed torque is 60 N.m and the rotational speed is 560rpm. The net weight is 12.2kg, and the package includes a controller bag and English manual. The main limitation is the wheel size: the listing specifies only this one wheel size, so it won't directly suit a smaller bike frame. It is also the more expensive of the two kits, with more components to install.
1000W 48V Front/Rear Hub Kit
This hub motor is built for a smaller wheel, with a tire and tube included. It is described as a brushless gearless hub motor with a 7-speed freewheel, hub widths for both front and rear, and support for standard 6-hole disc brakes. The listed max torque is 35 N.m, max RPM is 420, and the speed range is 0-40km/h. The front wheel weighs 8.5kg. Because it can be mounted on either end, it offers more frame flexibility. The trade-off is the lower motor voltage and power, plus the smaller wheel size. It is the lower-priced option and a simpler starting point for compact builds.
Final choice by use case
Choose the higher-voltage rear wheel kit when you are building a larger-wheel bike and want the higher listed voltage, torque, and LCD integration. Choose the lower-priced front/rear hub kit when your bike takes a smaller wheel, you want mounting flexibility, and you prefer the lower-priced start.
