Electric motorcycles and their derivative electric tricycles are segmented by application scenario, load capacity and structural design, with significant differences in assembly complexity across categories, which serves as the core basis for assembly line selection.
Electric Motorcycle (Two-wheeler) Classifications
- Commuter type: The mainstream mass-market product, with a curb weight of 80–150kg, simple frame structure and standardized components, suitable for high-volume standardized production.
- Cargo type: Features reinforced frames and extended rear racks, with a payload of 100–300kg, widely used for short-haul logistics in Southeast Asia and South America. Assembly requires additional reinforcement of load-bearing joints.
- High-performance type: Targeted at EU export markets, with a curb weight of 120–200kg, equipped with high-power motors, lithium battery packs and advanced electronic control systems. Assembly demands strict precision for high-voltage component docking and performance calibration.
Electric Tricycle Classifications
- Passenger type: Equipped with semi-closed or fully enclosed cabins, designed to carry 2–4 passengers, mainly used for short-distance public transit in rural and suburban areas of emerging markets. Assembly involves additional body structure and interior component installation.
- Cargo type: The most widely adopted variant, with a payload of 300–1000kg, featuring a reinforced chassis, extended cargo box and high-torque powertrain. Assembly requires high-precision tightening of chassis load-bearing components and reliable powertrain connection.
- Special-purpose type: Includes refrigerated, sanitation and last-mile delivery tricycles, with customized structures for specific scenarios. Assembly lines for these models require flexible configuration to adapt to non-standard component integration.
To match the differentiated assembly requirements of the above vehicle categories, plate chain and AGV assembly line solutions are available for varying production capacities, model mixes and regional compliance standards.
1. Details of Two Mainstream Electric Motorcycle Assembly Lines
1.1 Plate Chain Assembly Line
Core Principle
The frame of the electric motorcycle is fixed to the accumulation pallet of the plate chain via a dedicated positioning fixture, with workstations arranged on both sides of the line. The plate chain only runs at a constant speed during the workpiece transfer phase. When the pallet reaches the corresponding workstation, a photoelectric sensor triggers a stopper, the plate chain stops, and workers complete the assembly of corresponding parts in a static state. After the assembly task at the current workstation is completed, the stopper releases the pallet, which moves to the next station along the plate chain, and empty pallets are automatically recycled to the loading end for reuse.
Note: Mobile assembly during conveyance is strictly prohibited in electric motorcycle assembly lines to avoid safety risks caused by the shaking of heavy components such as batteries and frames, and to ensure the assembly accuracy of processes such as tightening and docking.
Core Advantages
- High production efficiency: 150%-250% higher than pure manual assembly lines, with a standard takt time of 70-100 seconds per unit, single-shift capacity of 180-350 units, and maximum annual capacity of 150,000 units. Workers do not need to manually handle workpieces, only focusing on their assigned assembly tasks, reducing invalid labor hours by more than 40%.
- Strong adaptability for mass production: Standardized operation processes control product consistency error within ≤0.8mm, reducing human-induced assembly errors by more than 60%. It is fully suitable for standardized production of single-model, high-volume, low-SKU commuter electric motorcycles, and is the preferred solution for mass-market electric motorcycle factories in Southeast Asia and South America.
Applicable Scenarios
Only suitable for mass production of 1-2 models on the same platform with minimal structural differences. It does not support fast model changeover for mixed-line production, making it ideal for cost-sensitive, stable-order commuter model projects.
Industry Standard Parameters
| Parameter Item | Industry Standard |
|---|---|
| Conveyance Speed | 0.3-2m/min, variable frequency adjustable (only runs during transfer phase) |
| Single Workstation Load Capacity | ≤350kg (matches the industry requirement that the curb weight of electric motorcycles is ≤300kg) |
| Accumulation Positioning Accuracy | ±1mm |
| Number of Workstations | 15-40 |
| Automation Rate | 10%-25% (only tightening and filling processes can be automated; the plate chain structure limits the integration of complex automation equipment) |
| Operational Availability | ≥97% |
| Model Changeover Time | ≥30 minutes (requires adjustment of fixtures and positioning blocks, low flexibility) |
1.2 AGV Intelligent Assembly Line
Core Principle
Laser/QR code navigation AGVs are used as the core conveyance carrier, equipped with customized tooling pallets to carry frames or semi-finished products. AGVs automatically travel along the system-planned path, stop and dock with power and communication systems when reaching designated workstations. After assembly is completed, the AGV automatically moves to the next station, and idle AGVs automatically return to the charging area for replenishment.
Core Advantages
- Highest flexibility in the industry: Supports mixed-line production of 100+ models with different sizes and configurations. No hardware adjustment is required for model changeover; only parameter switching on the MES system is needed, with changeover time ≤5 minutes, far exceeding the flexibility of traditional plate chain lines, perfectly suitable for high-end customized and small-batch personalized electric motorcycle production.
- Strong layout adaptability: No fixed guide rails are required, and the AGV travel path can be modified at any time according to plant structure and process adjustments, especially suitable for old plant renovation projects without large-scale civil construction.
- Perfect intelligent control capability: AGVs are equipped with IoT modules to upload real-time position, operation status and assembly progress data to the MES system for full-process quality traceability. It supports automatic obstacle avoidance, with operational safety ≥99.9%.
Applicable Scenarios
Suitable for small-batch, multi-SKU production scenarios with an annual capacity of 10,000-50,000 units, such as high-end electric motorcycles exported to the EU and customized modified models, catering to customers who need to frequently adjust product configurations and respond to niche market demands.
Industry Standard Parameters
| Parameter Item | Industry Standard |
|---|---|
| Navigation Accuracy | ±10mm |
| Maximum Travel Speed | 1.5m/s |
| Single AGV Load Capacity | ≤1000kg |
