This electric bicycle final assembly line is developed for mass assembly scenarios of urban electric bicycles, leisure electric scooters, lightweight electric two-wheelers and standard battery electric bikes. It belongs to non-standard complete vehicle conveying and assembly equipment for electric bicycle manufacturers and is the core main production line for standardized mass production of electric two-wheeler vehicles. The entire electric bicycle production line arranges workstations strictly in accordance with the forward assembly process logic of electric bicycles. It fully covers a complete set of standard mass-production procedures: frame loading, centralized pre-assembly of components, chassis system marriage, motor and battery power system assembly, instrument panel and vehicle wiring harness installation, wheel assembly, parts inspection and arrangement, vehicle power-on debugging, and full offline inspection. The equipment supports flexible mixed-model production for multiple vehicle types and enables fast switching between different frame specifications, battery layouts and configuration versions. It fully meets the standardized, large-scale and continuous mass production needs of small and medium-sized electric bicycle manufacturing enterprises, effectively improving finished vehicle assembly consistency and production delivery efficiency.
As the core load-bearing and conveying mechanism of the complete electric bicycle assembly line, it adopts an industrial heavy-duty slat conveying structure with high structural strength and sufficient load margin. It can stably carry electric bicycle frames and semi-finished vehicles for long-term continuous flow operation. The line is equipped with customized adjustable tooling support fixtures, which can quickly complete positioning according to different electric bicycle wheelbases and frame installation points. It effectively avoids frame offset, shaking and misalignment during assembly, and ensures assembly accuracy of each workstation. The full-line electrical system supports precise fixed-point stopping, segmented speed regulation conveying and emergency stop interlock protection, featuring stable operation and low failure rate, fully adapting to continuous mass production working conditions of electric bicycle factories.
The electric bicycle production line is equipped with standardized split-type pre-assembly auxiliary workstation modules, including frame pre-assembly bench, front and rear shock absorber assembly pre-assembly station, wheel hub motor power assembly pre-assembly station, and front fork steering system pre-assembly station. Large-volume and multi-process components are pre-assembled, pre-fitted and pre-tightened offline in advance, and transferred to the main line for integrated assembly after self-inspection. This mechanism effectively reduces main line operation pressure, avoids process accumulation and man-hour waste, accurately balances the overall takt time of the electric bicycle assembly line, improves the overall equipment efficiency (OEE) of the line, and forms a stable and efficient assembly line mass production mode.
Each workstation of the electric bicycle assembly line is equipped with complete standardized industrial assembly auxiliary systems, including pneumatic tool hanging slide rails, retractable hose reels, stabilized air supply pipelines and workstation material sliding tables. The on-site spiral telescopic air supply structure provides continuous and stable air source support for pneumatic torque wrenches, pneumatic tightening guns and other assembly tools, adapting to high-frequency and high-strength cyclic assembly operations. Multi-layer material storage racks are arranged in the workstation area to realize nearby storage and rapid picking of parts, reduce invalid walking and material searching time of operators, fully comply with lean production layout standards, and significantly improve single-station assembly efficiency and operation standardization.
The end of the electric bicycle production line integrates an all-in-one vehicle inspection and offline working section, covering full factory inspection procedures such as vehicle power-on functional detection, braking system performance verification, lighting and instrument function detection, line sequence inspection and structural tightness test. It conducts multi-dimensional comprehensive verification on the assembled electric bicycle to ensure that key systems such as vehicle circuit, braking, wiring harness and instruments operate normally and meet factory parameter standards. Qualified finished vehicles directly complete offline turnover and warehousing; for vehicles with assembly defects and functional abnormalities, an independent rework branch channel is specially set up to realize separate operation of qualified product circulation and defective product rework, effectively ensuring the factory pass rate of electric bicycle finished vehicles.
This electric bicycle production line adopts flexible modular overall design. Workstation tooling, positioning fixtures and assembly reference benchmarks support rapid model change and adjustment. It can quickly adapt to mass production of different types of electric bicycles such as standard electric bikes, portable electric bicycles and light electric scooters, and has good compatibility for vehicles with different wheelbases, frame structures and battery installation methods. A single electric bicycle assembly line can realize multi-variety and small-batch mixed alternate production, avoiding repeated investment in new production lines and effectively reducing fixed asset investment and later operation and maintenance costs of electric bicycle manufacturers.
Aiming at the industrial characteristics of concentrated assembly load and long-term uninterrupted production of electric bicycles, the line body slat chain, main support frame and bottom load-bearing base are all designed with load redundancy reinforcement. The structure has high rigidity and strong deformation resistance, and can adapt to 24-hour non-stop shift production mode of the factory. Under long-term high-load operation, the line body runs without deformation and jitter with stable conveying, which is highly suitable for the high-intensity and continuous mass production schedule of electric bicycle finished vehicles.
According to customers’ actual production capacity objectives and workshop manpower allocation, refined process man-hour splitting and workstation takt planning can be carried out. The standard single-unit production takt is controlled within 4~12 minutes per unit, and the full line can adapt to the annual production capacity planning of 20,000 to 200,000 electric bicycles. Meanwhile, the overall layout of the electric bicycle assembly line can be customized non-standard according to customers’ workshop size, site layout and inlet and outlet positions, supporting multiple layout forms such as linear and return type, with strong site adaptability.
The whole electric bicycle production line is equipped with industrial-grade safety protection system. Each workstation is equipped with emergency stop buttons, safety guardrails and infrared photoelectric induction devices. Automatic alarm and stop protection will be triggered in case of missing materials, line jamming and equipment abnormalities, eliminating potential safety hazards in operation. The whole line adopts centralized PLC programmable control system with stable operation logic. It can be seamlessly connected with factory MES system to realize real-time collection of workstation production data, automatic output statistics, real-time monitoring of equipment status and production data traceability management, meeting the intelligent production management requirements of modern electric bicycle manufacturing factories.
Suitable for electric bicycle professional manufacturing factories, light electric two-wheeler production enterprises and electric bicycle mass production bases. It is applicable to technical transformation and capacity expansion projects of electric bicycle manufacturers, including new construction of electric bicycle production lines, equipment upgrading of old electric bicycle assembly lines, production line takt optimization and standardized transformation of production processes.
The electric bicycle assembly line supports modular function expansion. According to customer production capacity and process requirements, optional expansion modules include frame suspension conveying line, spraying docking conveying equipment, automatic wheel assembly machine, precision parts filling equipment, finished vehicle rain detection line and AGV intelligent material handling system, which further improve the automation level and overall mass production capacity of the electric bicycle production line.
