(E-BIKE)Electric Bike production line

The picture displays a modern mass-assembly workshop for light electric bicycles. The core conveying equipment is a heavy-duty plate chain conveyor line, running horizontally through a long sequence of assembly workstations. Complete e-bikes sit directly on the flat metal plate trolleys of the main line and move step-by-step from one station to the next. Above each workstation, there is a multi-layer overhead hanging material rack system (orange support frames + layered material trays). These suspended racks hold pre-sorted parts directly above workers, eliminating long-distance walking to fetch components and greatly streamlining material supply. The workshop adopts a streamlined linear layout (can also be designed into U-shape upon request), with clear yellow safety marking lines on the polished concrete floor to separate walkways, material carts and assembly zones.

Production Line Configuration & On-site Working Principle

The whole assembly process is divided into five sequential core modules: raw part feeding, power system integration, body mechanical assembly, electrical debugging and finished vehicle inspection.

1. Parts feeding & workstation-side overhead material storage Spare parts are pre-distributed and placed on the layered overhead hanging racks above each workstation, matched to the BOM of corresponding e-bike models. Production scheduling is managed by the MES manufacturing execution system. Workers scan barcodes to confirm part correctness before assembly. This overhead storage design keeps the floor area clear and avoids stacking boxes on the ground.
2. Power system integration This is the key station for powertrain installation. Dedicated positioning jigs are used for motor mounting and battery pack fitting. The tooling can control assembly alignment tolerance within ±1 mm, ensuring stable contact of power connectors and avoiding poor power supply caused by offset installation.
3. Body mechanical assembly Workers install front forks, wheels, handlebars, front baskets, saddles, fenders and plastic body panels on the plate chain platform. The solid flat plate structure of plate chain conveyor can bear the weight of half-finished two-wheelers and prevent tipping during assembly operation.
4. Electrical system wiring and commissioning Install wiring harness, vehicle controller, dashboard, headlights, turn signals and brake cut-off switches. After wiring completion, power on the vehicle to test throttle response, lighting functions and brake electronic signals to catch circuit faults at this stage.
5. Finished vehicle performance testing station After mechanical and electrical assembly, finished e-bikes go through comprehensive offline functional tests: rolling road running test, braking performance test, power consumption inspection and appearance quality audit. Any non-conforming vehicles will be diverted to the rework zone for disassembly and adjustment, preventing defective products from entering packaging.

The plate chain main line can work independently or combine with double-speed chain modules according to customer output requirements. The production takt can be tuned between 90–120 seconds per workstation, to maintain balanced continuous mass production.

Main Assembly Workflow of E-Bike Assembly Line

1. Frame loading and fixing Place the bare e-bike frame onto the plate chain trolley and lock it with simple positioning supports.
2. Powertrain assembly Mount drive motor and battery pack; connect main power cables and high-voltage connectors.
3. Mechanical component fitting Install front fork, front/rear wheels, brake assemblies, handlebars, basket, seat and outer plastic covers.
4. Complete wiring harness installation Lay vehicle wiring harness, mount controller, instrument panel, lights and control switches.
5. Power-on electrical debugging Power on the vehicle; test throttle, lights, horn and brake power-off signal.
6. Full vehicle dynamic performance test Carry out roller running test, braking test and safety inspection.
7. Final quality audit & off-line Inspect appearance, fastener torque and test records. Qualified electric bikes are unloaded for packaging. Empty plate trolleys circulate back to the starting feeding station.

Core Technical Features

1. Heavy-duty plate chain main conveyor Wide flat metal plate carrying surface, stable bearing for half-assembled two-wheelers, anti-tipping during manual assembly. Low vibration and smooth step transfer between stations.
2. Overhead suspended multi-layer material rack system (visible in photo) Parts stored above workstations, floor space saving. Parts pre-sorted by station, reducing material transport and search time for operators.
3. Precision positioning assembly jigs Millimeter-level positioning for motor and battery installation, improving assembly consistency and reducing rework rate.
4. MES full-process digital traceability Barcode scanning for incoming parts, recording assembly parameters and test data for each individual e-bike, realizing end-to-end traceability.
5. Flexible mixed production capability By replacing simple positioning fixtures, one single assembly line can produce multiple styles of light electric bicycles. Layout can be linear or U-shaped based on factory building dimensions.
