Two-wheeler production lines, especially for electric vehicles, are highly automated and integrated systems designed for assembling electric bicycles and electric motorcycles. Here are the main features:

1. **Component Preparation**: The production line first prepares all necessary components, including frames, motors, batteries, controllers, and wheels.

2. **Frame Assembly**: The frame is the basic structure of the two-wheeler, usually welded and polished first to ensure its stability.

3. **Motor and Battery Installation**: The motor is the power source, and the battery provides energy. These components need precise and secure installation to ensure the performance and safety of the vehicle.

4. **Controller and Sensor Assembly**: The controller manages the vehicle's operation, and sensors detect various states like speed and battery level.

5. **Wiring Harness**: The wiring harness connects electronic components and must be routed according to the design diagram to ensure all systems function correctly.

6. **Wheel and Saddle Installation**: Wheels undergo dynamic balancing tests for smooth travel, and saddles are installed considering comfort and aesthetics.

7. **Final Inspection and Calibration**: After assembly, vehicles undergo functional tests and calibrations, including motor performance, braking systems, lights, and instruments, to ensure all parts operate correctly.

8. **Automated Conveyor Configuration**: Includes chain conveyor systems, automated assembly equipment like automatic screw machines and robotic welding machines, and quality inspection equipment such as motor test stands and battery performance testers.

9. **Information Management System**: Integrated with an information management system for real-time monitoring and analysis of production data, optimizing production processes.

10. **Performance Testing**: Sample vehicles are tested for power, economy, braking, and handling to ensure they meet design requirements and standards.

11. **Durability Testing**: Sample vehicles undergo long-term, high-intensity durability tests to ensure a long service life and reliability.

These features collectively enable two-wheeler production lines to efficiently and stably produce high-quality electric vehicles that meet market demands.
