Converting a bicycle is not one single decision: you may be choosing a complete motor-and-controller direction, replacing a wheel with a motorized one, or matching a controller to an existing setup. Wheel position, wheel size, voltage, motor type, and display protocol separate these four ebike motors, controllers, and displays options more clearly than price alone.
Quick take
The 24V 250W Electric Bicycle Conversion Kit E-Bike Cycling Brush Motor & Controller is the compact brush-motor route, while the 26 inch Front Wheel E-Bike Electric Bicycle Conversion Kit 48V 1000W Hub Motor is a front-wheel hub kit with pedal assist and an SW900 instrument in its package description. For a 20-inch rear-wheel format with a 7-speed freewheel, look to the 20-inch E-Bike Rear Wheel Motor, Electric Bicycle Conversion Kit +7-speed Freewheel. The Brushless Motor Controller X035-AB007 48V 18A Electric Bike Conversion Kit 5S is the focused controller choice for a 5S-meter setup rather than a motorized wheel.
Listed-price comparison
| Option | Listed price | Price position | Main format |
|---|---|---|---|
| 24V 250W Electric Bicycle Conversion Kit E-Bike Cycling Brush Motor & Controller | USD 68.46 | 24V, 250W brush motor and controller kit | |
| Brushless Motor Controller X035-AB007 48V 18A Electric Bike Conversion Kit 5S | USD 69.35 | 48V, 18A controller for a 5S meter | |
| 20-inch E-Bike Rear Wheel Motor, Electric Bicycle Conversion Kit +7-speed Freewheel | USD 164.07 | 20-inch rear motor wheel with 7-speed freewheel | |
| 26 inch Front Wheel E-Bike Electric Bicycle Conversion Kit 48V 1000W Hub Motor | USD 189.99 | 26-inch front hub kit, 48V and 1000W |
The listed prices span USD 68.46 to USD 189.99. The two lowest-priced choices serve notably different roles: one is a 24V brush-motor kit, and the other is a 48V 5S controller. Choose between them based on the component you need, not their close prices.
Decision matrix
- Starting with a front 26-inch conversion: Choose the FCH 26-inch front-wheel kit. Its title, pedal-assist attribute, and included instrument point to a wheel-based conversion arrangement.
- Building around a rear 20-inch wheel and gears: Choose the 20-inch rear wheel motor with 7-speed freewheel. The rear-wheel placement and freewheel are central to its configuration.
- Choosing a brush-motor conversion direction: Choose the SENDERPICK 24V 250W kit. Its title specifically combines a brush motor and controller.
- Replacing or specifying the electronic control component: Choose the X035-AB007 controller. It is identified as a 48V 18A controller and names compatibility with a 5S meter.
Product notes
24V 250W Electric Bicycle Conversion Kit E-Bike Cycling Brush Motor & Controller

This is the clearest match when the goal is a 24V, 250W conversion kit centered on a brush motor and controller. The description identifies a pure copper brush motor, an approximately 330rpm rated rotation speed, and aluminum and iron construction. Universal compatible-bike wording makes it relevant to broadly framed bicycle-conversion plans. Its black finish and 4.5kg gross weight are also specified. The main constraint is built into the configuration: this is a 24V brush-motor kit, not the 26-inch front hub or 20-inch rear wheel format represented by the wheel-based alternatives.
20-inch E-Bike Rear Wheel Motor, Electric Bicycle Conversion Kit +7-speed Freewheel

Pick this rear-wheel option when a 20-inch motorized wheel and a 7-speed freewheel are the priorities. It is described as a brushless gearless hub motor wheel with tire and tube, and the rear wheel format is paired with support for a standard 6-hole disc brake. The stated maximum torque is 35 N.m, while the description also identifies a maximum 420rpm figure. Its limitation is its specific wheel format: the stated tire size is 20 x 2.125, making it a focused choice rather than the 26-inch front-wheel configuration of the FCH kit.
26 inch Front Wheel E-Bike Electric Bicycle Conversion Kit 48V 1000W Hub Motor

For a front-wheel conversion based on a 26-inch rim, this FCH kit puts a 48V 1000W hub motor at the center of the build. The description names a 48V 26A controller, an SW900 instrument, full-throttle grip, and manual brake cut-off functionality; the attributes also specify pedal assist and an aluminum material. Choose it when those front-wheel kit elements suit the intended direction. The limitation is equally clear: it is configured around a 26-inch front wheel, so it does not target the 20-inch rear-wheel-and-freewheel layout.
Brushless Motor Controller X035-AB007 48V 18A Electric Bike Conversion Kit 5S

The X035-AB007 is the direct choice for an electronic control component identified as 48V and 18A, with compatibility stated for a 5S meter. Its description places it in electric bicycle, mountain bike, and electric scooter applications, while its silver finish distinguishes it visually from the black wheel and motor kit options. The key reason to select it is its specific 5S protocol focus. That same protocol is its limitation: it is a controller-oriented option for a 5S-meter arrangement, rather than a package centered on a 20-inch rear wheel or 26-inch front hub motor.
Final recommendation by use case
Choose the 24V 250W Electric Bicycle Conversion Kit E-Bike Cycling Brush Motor & Controller for a brush-motor-and-controller kit. Choose the 20-inch E-Bike Rear Wheel Motor, Electric Bicycle Conversion Kit +7-speed Freewheel when the rear 20-inch wheel and 7-speed freewheel define the project. Choose the 26 inch Front Wheel E-Bike Electric Bicycle Conversion Kit 48V 1000W Hub Motor for a 26-inch front hub configuration with pedal assist. Choose the Brushless Motor Controller X035-AB007 48V 18A Electric Bike Conversion Kit 5S when the priority is a 48V controller built around a 5S meter.
