Hub motor kits are all-in-one electric conversion solutions for two-wheelers including electric scooters, e-bikes and light electric motorcycles, integrating a BLDC hub motor with a matching controller, speedometer, throttle, wiring harness and other essential accessories.
Designed for easy installation and direct assembly, the hub motor kits eliminate the trouble of separate component matching, and provides a stable, high-performance power system for electric vehicle building, refitting and production.
As the most popular conversion kit for light electric two-wheelers, hub motor kits are favored for their compact structure, low maintenance and strong adaptability.
Core Components of a Standard Hub Motor Kit
A full-function hub motor kit usually includes 5 key parts, each undertaking a critical role in the power system:
- BLDC Hub Motor: The power core of the whole kit, directly installed in the wheel hub, drives the wheel to rotate without additional transmission parts;
- Electric Controller: The "brain" of the system, adjusts motor speed, current and torque, and protects the motor from overvoltage, overcurrent and overheating;
- Speedometer: Displays real-time riding data such as speed, voltage, battery capacity and mileage, with adjustable parameters for different usage scenarios;
- Throttle: The man-machine interaction part, controls the motor's power output and realizes speed adjustment;
- Complete Wiring Harness: Integrates ignition switch, relay, flasher and DC-DC converter, connects all components in a standardized way, and ensures safe and stable power transmission and signal communication.
