Choosing between two rear-wheel ebike conversion kits quickly becomes a wheel-size decision. The TBvechi kit is built for a 28-inch rear wheel, while the other kit is built for a 20-inch rear wheel. Both place a hub motor in the back, and both appear in the ebike motor, controller, and display space, but their listed prices and included controls split them clearly.
Quick verdict
If your bike uses a 28-inch rear wheel, the TBvechi 48V 1000W kit at USD 174.94 is the direct match. If your bike uses a 20-inch rear wheel, the 48V 1500W LCD kit at USD 290.00 is the direct match, and it adds an LCD display and power-off brake levers. The listed-price gap is USD 115.06.

Where the TBvechi kit fits best
The 28-inch kit is a complete rear-wheel conversion package for a bike that already uses a 28-inch wheel. It is listed as universally compatible, and the set includes a controller, controller bag, PAS, twist throttle with a five-star connector, brake handle, connectors, fuse, and harness wires. The hand brake lever is part of the listed package.
Where the 1500W LCD kit fits best
The 20-inch kit is the higher-powered option for a bike with a 20-inch rear wheel. The listing specifies a 48V 1500W brushless toothless hub motor, an LCD display, a 48V 1500W controller, and power-off brake levers. It lists a rated speed of 500RPM, motor efficiency of at least 82%, a maximum load capacity around 150kg, and 7 speed gears. Assembly is required, and the power-off brake levers are designed to cut motor power when the brake lever is pulled.
Product notes
#### 48 V 1000 W 28 in E-Bike Conversion Kit Electric Bicycle Rear Wheel Motor Set
The kit from TBvechi bundles a 48V 1000W rear motor, wheel, controller, controller bag, PAS, twist throttle with a five-star connector, brake handle, connectors, fuse, and harness wires. The 28-inch rear wheel size is the first thing to confirm against your bike. The kit is listed as universally compatible, and the hand brake lever is part of the package. The description includes a specific caution: connect the controller wires by matching the correct colors, otherwise the controller may be broken. That makes careful wiring a priority during installation. If a 28-inch rear wheel conversion with a throttle, PAS, and hand brake is what you need, this kit puts those parts in one listed package.
#### 20in Rear Wheel 48V 1500W Electric Bicycle Ebike Conversion Kit Hub Motor LCD
This kit centers on a 20-inch rear wheel with a 48V 1500W brushless toothless hub motor. It includes an LCD display, a 48V 1500W controller, and power-off brake levers. The spec list shows a rated speed of 500RPM, motor efficiency of at least 82%, a maximum load capacity around 150kg, and 7 speed gears. The 48V 20A lithium battery is not included, so plan for a separate battery source. Assembly is required. If a 20-inch rear wheel bike is what you have, and you want a display plus power-off brake function with a higher motor power rating, this kit lines up with your build.
Final choice by use case
Confirm your existing rear wheel size first. For a 28-inch bike, the 48V 1000W kit is the matching choice and groups the motor, controller, and controls in one set. For a 20-inch bike, the 48V 1500W kit is the matching choice and brings an LCD display, power-off brakes, and a 1500W motor into the build. Both are listed as black and new, so wheel size and the control package are what separate them.
