Choosing an ebike motor conversion kit can feel like juggling three specs at once: voltage, wheel size, and power. The kits in this guide range from a 36V 350W unit to a 72V 2000W rear wheel kit with LCD display, and the right pick depends on the wheel diameter your bike uses and the speed or torque you want.
Quick Take
For a 1000W hub motor with front or rear wheel use, the 1000W Electric Bicycle Front/Rear Wheel E Bike Motor Conversion Kit covers both positions. If you want a rear wheel conversion, the 48 V 1000 W 28 in E-Bike Conversion Kit Electric Bicycle Rear Wheel Motor Set from TBvechi offers 1000W at 48V. If you want maximum listed power, the 72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W is the highest-power option. For a lower-power conversion, the 36V 350W Electric Bicycle Brushless Motor Kit has the lowest listed price.

Product Notes
36V 350W Electric Bicycle Brushless Motor Kit
The 36V kit is the least expensive option here, and it is aimed at spoke-wheel bikes. It includes a brushless motor and multifunctional controller with speed changes, reverse, and anti-theft functions, though anti-theft accessories are not included. The motor is rated at 350W, 330RPM, and 10.85N·m torque, with efficiency listed at 78% or higher. Its aluminum housing, pure copper coils, and rare earth magnet steel are the specified materials. Before you order, confirm your wheel's chainwheel spacing against the listed chainwheel inner diameter of 35mm, outer diameter of 134mm, and teeth space of 12.7mm. This is a motor-and-controller conversion kit, so the fit depends on your existing spoke wheel.
1000W Electric Bicycle Front/Rear Wheel E Bike Motor Conversion Kit Hub 20" 48V
This 1000W front/rear wheel kit comes in at USD 147.57 and is built around a brushless gearless hub motor. The package includes a 20-inch wheel with tire and tube, plus a 7-speed freewheel on the rear motor wheel. It lists support for standard 6-hole disc brakes, along with max efficiency of 88.7%, max torque of 35N·m, max RPM of 420, and a speed range of 0-40km/h. The available wheel tire size is 20" x 2.125, and the hub width is listed as 100mm front or 135mm rear. The main limitation is the fixed 20-inch wheel diameter, so you need a bike that works with that size. If you want a smaller-wheel 1000W hub motor with disc brake support, this is the one to start with.
48 V 1000 W 28 in E-Bike Conversion Kit Electric Bicycle Rear Wheel Motor Set
The TBvechi 48V 1000W kit is a 28-inch rear wheel conversion set, and its listed contents cover the motor, wheel, spokes and aluminum circle, controller, controller bag, pedal assist sensor, twist throttle, brake handle, connectors, fuse, and harness wires. It is marked as compatible with a universal bike type, and the brake type is hand brake. The kit also includes a note to match controller wire colors carefully to avoid damaging the controller. Because it is a rear wheel kit, it will not suit a front-wheel build, and the 28-inch size is fixed. If you want a complete 28-inch rear wheel assembly with pedal assist and hand brake, this set is the one.
72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W
The 72V 2000W rear wheel kit is the highest-power option here, with a 27.5-inch wheel, 9-speed flywheel, controller, LCD display, ordinary throttle, pedal assistant sensor, power-off brake lever, controller bag, and English manual. It is rated at 560rpm and 60N·m torque, and the wheel material is aluminum. The listing also includes a 1-year manufacturer warranty. At 14kg gross weight, this is the heaviest package of the four. The trade-off is the wheel size: it is a 27.5-inch rear wheel, so your frame needs to match. If you want the most power and a display in the kit, this is the one.
Final Recommendation by Use Case
For 1000W front or rear wheel use, choose the 1000W Electric Bicycle Front/Rear Wheel E Bike Motor Conversion Kit Hub 20" 48V. For a rear-wheel setup, go with the 48 V 1000 W 28 in E-Bike Conversion Kit Electric Bicycle Rear Wheel Motor Set. If you want the highest power, the 72V E-Bike Motor 27.5" Rear Wheel LCD Electric Bicycle Conversion Kit 2000W is the match. For the lowest listed price and a 36V 350W motor, the 36V 350W Electric Bicycle Brushless Motor Kit E-Bike Conversion Installation Kit is the 36V choice.
