Key Features
Enclosed cabin structure provides protection from rain, wind and sun for more practical year-round operation.

1500W–3000W electric motor options allow the vehicle configuration to be matched to different load, terrain and performance requirements.

Hydraulic disc braking system with front and rear discs provides controlled braking performance and easier maintenance access.

McPherson independent front suspension helps absorb road irregularities, while the integrated rear axle provides a compact rear-wheel structure.

60V lead-acid or LiFePO4 battery options support different purchasing budgets, operating requirements and battery lifecycle expectations.

Typical Applications
Urban short-distance mobility:
Suitable for local commuting, neighborhood travel and short daily trips where a compact enclosed vehicle is preferred.
Community and residential areas:
Used for internal transportation in residential communities, retirement communities and large private developments.

Tourist destinations:
Suitable for resorts, scenic areas and leisure facilities requiring low-speed passenger transportation.
Industrial and commercial sites:
Can be configured for employee or visitor movement across factories, campuses, warehouses and large facilities.

Manufacturing Processes
The manufacturing operation is supported by a 150,000 m² production facility, vertically integrated processes including:
- Automatic stamping – Sheet-metal components are formed using automatic stamping equipment for dimensional consistency.
- Tube and profile bending – Structural tubes and profiles are processed using dedicated bending equipment according to approved drawings.
- Automatic welding – Body and structural assemblies are welded using automated welding equipment to improve joint consistency.
- Electrophoretic coating – Selected metal components receive electrophoretic treatment for corrosion protection and coating adhesion.
- Injection molding – Plastic components are produced using large injection molding equipment according to component specifications.
- Surface preparation and painting – Body panels are prepared, painted and cured through controlled paint-booth and drying-kiln processes.
- Vehicle assembly – Chassis, suspension, braking system, motor, battery, electrical system, cabin components and interior equipment are assembled on the production line.
Engineering Validation & Testing Standards
Before mass shipment, every vehicle model undergoes rigorous performance, environmental, and structural testing in accordance with international EV quality control protocols:
- Rain & Waterproofing Test: 30-minute high-pressure water spray chamber test at IPX5 equivalent severity to verify cabin seal integrity and motor/controller insulation.
- Gradeability & Torque Validation: Fully loaded (300 kg payload) continuous incline driving test on a 20% (11.3 degree) slope to verify motor thermal management and anti-rollback braking safety.
- Chassis Endurance & Vibration Test: Simulated rough-road durability test over 1,000 km on bumpy, cobblestone, and pothole tracks to evaluate suspension fatigue and weld seam structural integrity.
- Electrical System Insulation: 100% high-voltage insulation resistance testing on the harness and battery management system (BMS) before warehouse dispatch.
Certifications & Compliance
- EEC / EU Type Approval: Applicable to vehicle configurations that meet the relevant EU L-category type-approval requirements. The exact approval category and scope should be confirmed against the final vehicle configuration and destination market.
- Certificate of Conformity (CoC): A vehicle conformity document supplied for vehicles manufactured in conformity with the approved type where applicable. Under EU Regulation 168/2013, a CoC accompanies each vehicle manufactured in conformity with an approved vehicle type.
- WVTA (Whole Vehicle Type Approval): A type-approval framework allowing an approved vehicle type to be marketed across the EU without repeating the complete approval process in every EU country, subject to applicable requirements.
- ISO 9001:2015: Quality management system standard applicable to the manufacturing organization.
- CCC: China Compulsory Certification is applicable only to products within China's mandatory CCC catalogue and relevant implementation rules.
Compliance note: Certification, approval and documentation availability depend on the final vehicle configuration, production version and destination market. Buyers should confirm the required approval package before placing a market-specific order.
