Motors, controllers, and displays are the core of any e-bike conversion, but the right pick depends on what you're starting with. Do you need a complete wheel, a motor-and-controller combo, or just a replacement controller? The four options here cover all three scenarios, from a 24V brushed motor kit to a 2000W rear hub.
Quick Take
- 24V Brushed Motor Kit - The low-cost complete set for light e-bikes and DIY projects.
- 48V Brushless Motor Controller - A replacement controller for existing brushless motor setups.
- 36V Brushless Motor Kit - A motor-and-controller pair for spoke-wheel bikes.
- 72V Rear Wheel Kit - The high-power complete rear hub kit.

Product Notes
24V Brushed Motor Kit
This entry-level set bundles everything needed for a basic conversion: the 24V 250W DC brushed motor, a chain, freewheel, freewheel adapter, controller, mounting plate, accelerator handle, and left handle sleeve. It's designed for standard 0.87-inch handlebars and 16-28-inch wheels, so it can fit many existing bikes and DIY e-bike projects. The rotary throttle handlebar gives you twist-grip control, and the motor has a rated torque of 0.8 N·m with an efficiency rating of at least 78%. At $63.38, it's the lowest-priced complete kit in this group. Pick this when you want a low-cost, full parts list and you're comfortable with a brushed motor's modest output. The trade-off is the 250W rating and the need to confirm that the included 38-section chain and 16-tooth freewheel match your bike's drivetrain.
48V Brushless Motor Controller
This is the component-level choice for riders who already have a brushless motor and need a new controller. It's specified for e-bikes, mountain bikes, and scooters, and it's set up for universal bike compatibility. The 48V 25A controller is paired with a 5S meter protocol, and the important caveat is that you should confirm your original controller's label and connector before ordering to avoid display error codes. It's designed to work with motor power levels from 250W all the way to 1000W, making it a flexible replacement part. This works well if you're repairing or upgrading an existing brushless setup. The limitation is that it's a controller only, so the motor, display, and wiring will come from your existing or separate build.
36V Brushless Motor Kit
This conversion installation kit pairs a 36V 350W brushless motor with a multifunctional controller that provides speed changes, reverse, and anti-theft readiness (the anti-theft accessories are not included). The motor uses an aluminum housing, pure copper coils, and rare earth magnet steel, and it's built for spoke-wheel bikes. The specs give exact chainwheel measurements: inner diameter 35mm, outer diameter 134mm, and teeth spacing 12.7mm, which is useful if you're checking fitment. With 330RPM and 10.85 N·m of torque, it's a clear step up in pulling power from the 250W brushed option. At $90.43, it sits between the low-cost brushed set and the high-power hub. It's a solid match for builders who already have a battery and display ready, since the kit centers on the motor and controller.
72V Rear Wheel Kit
The highest-priced kit in this comparison is also the most complete. It arrives as a 27.5-inch rear wheel with an aluminum rim, a 9-speed flywheel, motor, controller, LCD display, ordinary throttle, pedal-assist sensor, brake lever, controller bag, and an English manual. Running on 72V and 2000W, it delivers 560RPM and 60 N·m of torque, which makes it the serious option for riders who want strong hill-climbing ability. It comes with a 1-year manufacturer warranty. At $309.52, it's the premium in this group, and you'll need a 72V battery (not listed in the package contents) plus a frame that fits a 27.5-inch rear wheel. Select this when you want a complete rear hub system with display and pedal-assist in one package.
Final Recommendation by Use Case
If you're looking for a low-cost, complete conversion for a light e-bike, the 24V Brushed Motor Kit is the most straightforward starting point. If you already have a brushless motor and need a controller, the 48V Brushless Motor Controller covers a wide power range. For a spoke-wheel bike that needs a motor and controller together, the 36V Brushless Motor Kit offers balanced performance. And if you want a complete rear wheel with high power, the 72V Rear Wheel Kit is the most comprehensive solution.
