Choosing among ebikes conversion kits is less about picking the biggest wattage number and more about matching the motor wheel to the bike you want to convert. Start with wheel diameter and whether you want a front or rear setup, then narrow the field by battery requirements and the controls named with each kit.
Quick take
The four choices divide into a focused 20-inch front motor wheel, a 20-inch rear 1500W kit with an LCD display, a 26-inch rear 1000W kit, and an FCH option covering 24- and 26-inch front or rear configurations. The P1 front motor wheel has the lowest listed price, while P2 carries the highest listed price and names a 48V 1500W controller. P3 and P4 sit close together in the middle, but serve different wheel-format decisions.
Listed price comparison
| Conversion kit | Listed price | Position across the range |
|---|---|---|
| 1000W 20-inch Front Motor Wheel | USD 160.58 | |
| 20-inch Rear 48V 1500W Hub Motor LCD | USD 298.32 | |
| 26-inch Rear 48V 1000W Hub Motor | USD 183.50 | |
| 24/26-inch Front/Rear 48V Kit | USD 189.99 |
The full listed-price spread is USD 137.74. That makes wheel fit and the kit's stated components especially important: two similarly priced options can still be meant for quite different builds.
Decision matrix
- Need a 20-inch front-wheel route: choose the 1000W 20-inch Front Motor Wheel, which specifies a 20-inch x 2.125 tire size and front placement.
- Want a 20-inch rear setup with an LCD: the 20-inch Rear 48V 1500W Hub Motor LCD is the direct match.
- Converting around a 26-inch rear wheel: the 26-inch Rear 48V 1000W Hub Motor is the size-specific choice; it names 48V lithium or lead-acid battery types in the 17-20Ah range.
- Still deciding between 24- or 26-inch wheel formats and front or rear placement: the FCH 24/26-inch kit covers those alternatives in its title.
Product notes
20-inch Front Motor Wheel
At USD 160.58, the 1000W 20-inch Ebike Front Wheel Electric Bicycle Motor Conversion Kit is built around a front integral motor wheel for the named 20-inch x 2.125 tire format. Its brushless gearless hub motor is described with a maximum 35 N.m torque figure, maximum 420 RPM, and support for a standard six-hole disc brake. Choose it when your conversion plan already calls for that specific front-wheel size and format. The important constraint is its focused package list: it identifies one front motor wheel, rather than describing a broader controller-and-display package.
20-inch Rear Hub Motor with LCD
The USD 298.32 20-inch Rear Wheel 48V 1500W Electric Bicycle Ebike Conversion Kit Hub Motor LCD is the most control-oriented rear option here. It names an LCD display, a 48V 1500W controller, a power-off brake lever, and a PAS sensor alongside its rear-wheel layout. This is the pick for a 20-inch rear conversion where those named electronics are central to the build. Assembly is required, and the specified 48V 20A lithium battery is not included. That battery requirement should be part of the plan from the outset.
26-inch Rear Hub Motor
At USD 183.50, the 26-inch Rear Wheel Electric Bicycle EBike Conversion Kit Hub Motor Cycling 48V 1000W targets a larger rear-wheel conversion than either 20-inch choice. The kit pairs its 48V 1000W designation with a brushless, toothless motor description and names an efficiency figure above 80%. It is a sensible match when the rear wheel must be 26 inches and the ability to use either 48V lithium batteries or lead-acid batteries is relevant. Its stated battery options are not included, so the wheel kit and battery remain separate parts of the build.
24/26-inch Front/Rear 48V Kit
The FCH 24-inch 26-inch Electric Bicycle Conversion Kit is priced at USD 189.99 and stands apart by naming both front and rear wheel configurations plus 24-inch and 26-inch wheel sizes. It also specifies a brushless gearless motor, aluminum material, and pedal assist. Choose it if your key decision is between those stated wheel diameters and motor positions rather than a single fixed wheel format. The title spans both 1000W and 1500W configurations, so select the particular wheel position and motor-output arrangement that suits your intended conversion.
Final recommendation by use case
Choose the 20-inch Front Motor Wheel when its maximum 35 N.m torque specification is the priority in a focused front-wheel component. Choose the 20-inch Rear Hub Motor with LCD when you have a separate 48V 20A lithium battery plan and want the named display and controller setup. The 26-inch Rear Hub Motor is the direct fit for a fixed 26-inch rear-wheel conversion. Pick the FCH 24/26-inch kit when pedal assist matters and you want to decide among its stated wheel-size and front/rear configurations.
