If you're converting a bike to electric, the first big fork in the road is power vs. package. Do you want a complete component bundle or just the motor wheel itself? That's the trade-off between these two conversion kits: a 27.5-inch rear wheel running 72V with a 2000W motor and a long list of included electronics, versus a 20-inch, 48V 1000W hub motor wheel with a significantly lower listed price.
Quick verdict: If you want every conversion component listed in one package, the 72V 2000W 27.5-inch rear-wheel kit is the straightforward choice. If you need a compact 20-inch wheel and are ready to build the surrounding electronics yourself, the 1000W hub motor wheel is the lower-priced starting point.
| Product | Listed Price | Price Indicator | Wheel Size | Motor | Package Highlights |
|---|---|---|---|---|---|
| 72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W | USD 309.52 | 27.5-inch | 2000W, 72V | Controller, LCD display, 9-speed flywheel, throttle, pedal assist sensor, power-off brake lever, controller bag | |
| 1000W Electric Bicycle Front/Rear Wheel E Bike Motor Conversion Kit Hub 20" 48V | USD 147.56 | 20-inch | 1000W, 48V | Motor wheel, tire and tube, 7-speed freewheel |
Where each product wins
- The 2000W kit wins on completeness and power. It comes with a controller, LCD display, 9-speed flywheel, throttle, pedal-assist sensor, and power-off brake lever, all listed in the package. Its 72V/2000W motor is the higher-spec powertrain.
- The 1000W wheel wins on price and compactness. It lists at USD 147.56, which is about USD 162 less than the 2000W kit, and the smaller wheel suits tighter frames. It also lists a 3-year manufacturer warranty, while the 2000W kit lists a 1-year warranty.
72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W
This kit is a complete conversion bundle for a 27.5-inch rear wheel. The included components go beyond the motor wheel: a controller, an LCD display, a 9-speed flywheel, a throttle, a pedal-assist sensor, a power-off brake lever, a controller bag, and an English manual are all listed. The motor is a 2000W unit running at 72V, with a listed torque of 60 N.m and a wheel made of aluminum. If you want to avoid hunting for separate parts, this is the package that spells everything out. The main limitation is the higher listed price of the two, and the 27.5-inch size is only relevant for a full-size rear frame.
1000W Electric Bicycle Front/Rear Wheel E Bike Motor Conversion Kit Hub 20" 48V
The 20-inch 1000W hub motor wheel is the lower-priced option at USD 147.56. The description highlights a quiet brushless gearless hub motor, a maximum efficiency of 88.7%, and a max torque of 35 N.m. The package list shows the motor wheel, tire, and tube, plus a 7-speed freewheel. That focus on the wheel itself is the key limitation: if you need a controller, display, or throttle to complete the conversion, those are not detailed in the package contents, so plan your build around the wheel alone. For a compact 20-inch bike, this wheel brings a high-efficiency motor to a tighter frame at a lower listed price.
Final choice by use case
- Choose the 72V 27.5-inch 2000W rear-wheel kit if you want a full electronics bundle and a high-voltage, high-power motor for a full-size bike, and you're comfortable with the higher listed price.
- Choose the 20-inch 1000W 48V hub motor wheel if you're building a smaller-wheel bike and want a lower-priced motor wheel that leaves the accessory choices open.
