The Decision Problem
Choosing an ebike motor, controller, and display isn't as simple as picking the most powerful motor. The controller has to speak the same protocol as your display, the wheel has to fit your frame, and the motor voltage has to line up with your battery. With prices spanning $72.29 to $261.69 across four conversion kits, the right choice depends on what you already have and what you want to end up with.
Quick Take
Decide first whether you're replacing a controller or building a complete wheel. Then match the wheel size and voltage to your existing bike. These four options split into a controller-only part, two complete wheel conversion kits, and a lower-voltage motor-and-controller combo.

Decision Matrix
- Choose the X056-AXD001 when you already have a motor and display and just need a replacement controller rather than a full kit.
- Choose the complete motor-and-wheel set when you want the bundle that includes the wheel, motor, controller, brake handle, connectors, fuse, and wiring in one package.
- Choose the front-hub kit when the motor should be mounted at the forward end of the bike.
- Choose the motor-and-controller combo when your bike is a spoke-wheel model and you want reverse and anti-theft controller functions.
Product Notes
X056-AXD001 Brushless Motor Controller
If you already have a motor and display and simply need a replacement controller, this is the most direct path in the set. It's a 25A brushless controller with a 250W to 1000W energy range, so it can work with different motor sizes. The catch is the 5S protocol: if the controller doesn't match your display, you may see error codes, and you'll need to confirm your original controller's label and connector before ordering. That makes it a part for someone who already understands their existing ebike system, not a grab-and-go conversion kit.
48V 1000W Rear-Wheel Conversion Kit
This is the complete package for a 28-inch rear-wheel build. The kit includes the rear motor wheel, controller, controller bag, PAS, twist throttle, brake handle, connectors, fuse, and harness wires, so you're not piecing together a dozen parts. The hand brake is included, which keeps the control setup simple. The trade-off is that it's built around a 28-inch rear wheel, so you'll need a frame that matches that size. If you're going for a front-wheel drive setup or a smaller wheel, this rear-wheel kit is the wrong direction.
1500W Front-Wheel LCD Conversion Kit
This front-wheel conversion kit is the highest-power option in the lineup, with a color display that shows gear, speed, mileage, and battery level. It also includes a PAS sensor, thumb throttle, and brake levers that cut motor power when you brake, and the disc brake compatibility makes it a good match for a bike already set up with disc brakes. The limitation is the front-wheel format: this kit is designed for a 26-inch front wheel, so it won't fit a different front wheel size or a bike that needs rear-wheel drive.
36V 350W Brushless Motor Kit
This spoke-wheel kit pairs a brushless motor with a multifunctional controller, and it includes speed change, reverse, and anti-theft functions in the controller. The motor is rated at 330RPM and 10.85N·m of torque, and the aluminum housing, pure copper coils, and rare earth magnet steel suggest a durable build. The chainwheel measurements (35mm inner diameter, 134mm outer diameter, 12.7mm teeth space) let you check fit against your frame. The limitation is that it's meant for spoke-wheel bikes, so if your bike uses a different wheel construction, this isn't the kit to choose.
Final Recommendation by Use Case
- Controller-only upgrade: Choose the X056-AXD001 Brushless Motor Controller if you already own the motor and display and just need the controller to complete the chain.
- Complete motor-and-wheel conversion: Choose the complete motor-and-wheel set when you want one package that contains the wheel, motor, controller, brake handle, and wiring.
- Front-hub conversion: Choose the front-hub conversion kit for a forward motor installation.
- Spoke-wheel motor and controller build: Choose the spoke-wheel motor/controller kit if your bike uses spoke wheels.
