1. The Detour Most Sales Reps Take
Sales reps selling hub motors or lithium battery packs typically enter the bicycle and e-bike industry through the obvious front door — contacting the supply-chain procurement teams at brand-name vehicle manufacturers such as Yadea, Aima, or Niu, collecting buyer lists, then working through them one by one. This approach is not entirely without results, but the yield is poor: top-tier brand manufacturers' supply chains have been locked in by established solution providers for years, new vendor qualification cycles routinely stretch to six months or more, and brand-name vehicle manufacturers are not the entities actually designing motors or battery packs — they are system integrators.
The companies in this industry that genuinely select motors and configure lithium battery pack solutions are not necessarily the brand owners. They are contract vehicle assemblers, manufacturers fulfilling export EPAC orders for the EU market, and specialized component factories further down the chain.
Supply-chain stratification is the answer. Vehicle assemblers sit at the top. Below them are major assemblies — motors, controllers, battery packs. Below those sit finer components: wheel sets, drivetrain kits, brakes, chargers, instrument clusters. Each tier has its own procurement logic and its own factory entities. Selling into a given tier means finding the genuine manufacturing entities at that tier — not standing in line at the vehicle assembler's front gate.
2. What Factories in This Industry Look Like
Industrial Clusters: Three Hubs, One Division of Labor
Bicycle and e-bike factories in China are highly concentrated, centered on three regions.
Tianjin Wuqing, Wangqingtuo is the densest industrial cluster for complete vehicles and components. At its peak, Wangqingtuo town hosted more than 1,000 vehicle and component enterprises; in 2022 it produced approximately 10 million bicycles and 2.2 million e-bikes (Xinhua figures). The cluster encompasses both vehicle assembly plants and deep-tier suppliers — frame welding shops, wheel assembly plants, plastic injection molders — with the supply chain largely self-contained within the town.
Jiangsu Wuxi and Kunshan form the primary manufacturing base for Taiwan-funded brands including Giant, Merida, and Yadea. Vehicle factories here operate at scale under standardized management and generate sustained high-volume demand for upstream components, though entry barriers are correspondingly higher.
Guangdong Shenzhen and Dongguan concentrate high-end carbon-fiber road bike and shared-bicycle manufacturing, along with some of the premium OEM bicycle factories exporting to Europe and North America.
Zhejiang Jinhua and Yongkang are traditional strongholds for bicycle components; some contract suppliers for Luyuan and Lima are located in Zhejiang, and there is a meaningful concentration of motor and controller manufacturers.
Genuine Factories vs. Badge Assemblers
In Tianjin Wangqingtuo, a significant number of operators are "badge assemblers": they source bare frames, procure ready-made parts, assemble them, affix a house brand, and ship — with no welding line, no coating line, and no in-house electrical testing capability. These entities have limited technical judgment about motor and lithium battery procurement, low switching costs, and poor stickiness. They also typically lack CCC certification (mandatory for e-bikes since 15 April 2019).
The most direct way to identify a genuine factory is to check its CCC certificate: certificates issued by CQC and CTC must list a factory name and address matching the actual production site, and are publicly verifiable on the CQC website. A secondary signal is job postings — ongoing recruitment for frame welders, coating workers, and final-assembly-line operators indicates an active production line rather than pure trading assembly.
Factories exporting EU EPAC (Electrically Power Assisted Cycles) vehicles must also hold EN 15194 certification, a quality filter that effectively requires full electrical safety testing capability.
3. A Three-Step Method: Walk Down from Vehicle to Component, One Tier at a Time
Step 1: Establish Which Tier Your Product Sells Into
Supply-chain stratification is not an exercise in diagramming — it is the mechanism for locking onto procurement decision-makers with real buying authority.
Vehicle assemblers (top tier): Brand manufacturers such as Yadea and Aima, plus OEM contract assemblers. Top-tier factories buy in large volumes, but procurement decisions typically reflect supplier relationships established years earlier, making entry cycles long. Motors and batteries are usually purchased as complete solution packages from Tier 1 solution providers — selling components directly to vehicle assemblers generally requires first becoming a supplier to those Tier 1 integrators, not engaging the vehicle assembler's procurement team directly.
Major-assembly suppliers (second tier): Dedicated motor factories (hub motors, mid-drive motors) and dedicated lithium battery pack factories (compliant with GB 43854-2024, mandatory for new vehicle models from 1 November 2024). These factories source copper wire, silicon-steel laminations, cells, and BMS boards — making them the direct customers of suppliers selling raw materials and key components. Penetrating this tier is far more efficient than targeting brand-name vehicle manufacturers.
Precision component factories (third tier): Factories specializing in drivetrain kits (chains, freewheels, derailleurs), wheel sets (hubs, spokes, rims), and disc-brake systems, as well as charger, instrument cluster, and controller manufacturers. This tier purchases precision stampings, injection-molded parts, and electronic components; procurement decisions are more technically driven, and product specifications are clearly defined.
Summary: Suppliers of motor windings or silicon-steel laminations should prioritize major-assembly motor factories. Suppliers of lithium cells or BMS solutions should prioritize dedicated battery pack factories. Suppliers of precision hardware should target drivetrain and wheel-set manufacturers.
Step 2: Use Industry-Specific Signals to Identify Factories in an Active Procurement Window
Within a single industrial cluster, two hundred factories may exist, but at any given moment only a fraction are actively procuring. The following signals identify factories with an open window.
New national-standard model-recertification window: GB 17761-2024 takes effect on 1 September 2025, introducing mandatory changes to vehicle weight, speed, and electrical-safety parameters for e-bikes. Recertification drives motor specification adjustments, controller software upgrades, and lithium pack compliance redesigns — creating a concentrated entry window for motor and battery suppliers from now through the end of 2025.
Lead-acid to lithium conversion: Industry data show the lithium battery adoption rate for two-wheeled e-vehicles rising steadily from a 15% baseline. A portion of mid-size vehicle assemblers and battery pack suppliers are migrating production lines from lead-acid to lithium, generating active demand for aluminum housings, BMS boards, and 18650 or prismatic cells.
EU EPAC export orders: EN 15194 is the mandatory certification for EPAC (pedal-assist cycle) products sold in the EU, covering strict parameters including motor output (≤250 W) and assisted speed cutoff (25 km/h). Factories taking EU orders have specific requirements for motor performance curves and controller algorithms, making them high-value entry points; the pre-Chinese New Year period is a peak season for European market orders.
Shared-bicycle procurement rounds: Shared-bicycle operators issue periodic procurement tenders with large-volume standardized requirements for frames, wheel sets, and brake systems — a concentrated order window for wheel-set and braking-system suppliers.
Hiring signals: Factories posting sustained openings for power-battery engineers, motor test technicians, or BMS development engineers are in the middle of solution upgrades or new-product development and should be prioritized for follow-up.
Step 3: Use Tianxia Gongchang to Filter for Genuine Factories and Export the List
Steps 1 and 2 narrow the supply-chain tier and identify procurement signals. Step 3 is confirming that every name on the list represents a genuine manufacturing entity.
Log in to Tianxia Gongchang, overlay bicycle and e-bike sub-industry filters with industrial clusters including Tianjin Wuqing, Jiangsu Wuxi and Kunshan, and Guangdong Shenzhen and Dongguan. Tianxia Gongchang covers 4.8 million real manufacturing enterprises in China and applies factory-identification logic to each entity, separating traders and badge assemblers from genuine manufacturers. After filtering, cross-check the following signals: whether a CCC certificate can be verified, whether job postings include production-line roles, and whether the factory participates in industry trade shows such as the China International Bicycle Exhibition.
Once badge shells and traders are removed, classify the list by supply-chain tier and sort by procurement-signal priority. Suppliers of motors should prioritize battery pack factories mid-way through lithium conversion; suppliers of lithium packs should prioritize export-oriented factories actively pursuing EN 15194 certification. A clean list saves time that, when costed out, exceeds a full sales-person-month — roughly 25,000 to 30,000 RMB.
4. How to Use Tianxia Gongchang in the Bicycle and E-Bike Industry
Factory-Identification Baseline: CCC Certification and Production Lines Are the Dividing Line
One of the core identification challenges in the bicycle and e-bike industry is that business-registration data for badge assemblers and genuine vehicle factories are nearly indistinguishable: both register in Wuqing or Yongkang, both list "electric bicycle manufacturing" as their business scope, and both can produce some form of product catalog. The difference is that a genuine manufacturing factory holds a CCC certificate with an address matching the actual production site and operates its own welding, coating, and final-assembly lines; a badge assembler buys loose parts, swaps brand labels, and ships — it has no independent component-selection requirement and no technical dialogue capability.
Business-registration lookup tools such as Qichacha or Tianyancha cannot distinguish between the two. Tianxia Gongchang uses genuine manufacturing capability as the identification baseline, removing trading entities from the manufacturing entity list. Log in to Tianxia Gongchang, filter by bicycle or e-bike sub-industry and industrial cluster, and note the share of entries flagged as non-factory entities — that figure directly quantifies how much of an unfiltered customer list consists of wasted visits.
Industry-Specific Filtering Path
When prospecting for bicycle and e-bike factory customers on Tianxia Gongchang, the recommended filter stack is:
- Supply-chain tier: OEM vehicle assemblers, dedicated motor factories, lithium battery pack suppliers, precision component factories (select the tier corresponding to your product)
- Industrial cluster: Tianjin Wuqing Wangqingtuo (vehicles + full component range, dense), Jiangsu Wuxi/Kunshan (Taiwan-funded OEM vehicles, export-oriented), Guangdong Shenzhen/Dongguan (high-end carbon fiber + shared bicycles, export-driven)
- Certification signals: Verifiable CCC certificate, EN 15194 certification record (EU EPAC export), GB 43854-2024 lithium battery safety certification status
- Size range: Motor specialists and lithium battery pack factories in the 50–300-employee band are the most active component-selection customers; top-tier brand supply chains are comparatively locked in

6. Go One Link Further Down the Chain, and the List Gets Sharply Cleaner
Inefficiency for upstream sales in the bicycle and e-bike industry ultimately comes down to conflating the supply chain — treating badge assemblers as motor-and-battery-buying factories, treating brand operations companies as manufacturers with production lines, and spending significant time on entities with no real procurement authority.
This industry's supply chain has clearly defined tiers: OEM vehicle assemblers handle final integration and component selection; dedicated motor factories and lithium battery pack suppliers are the genuine component-development entities; and precision component factories below them carry their own, more specialized procurement needs. Each tier has a distinct procurement decision chain, distinct decision-makers, and distinct entry signals. Treating the industry as a single undifferentiated audience means aiming at everyone and hitting no one.
Tianxia Gongchang removes trading entities from the pool of 4.8 million real manufacturing enterprises in China first, then segments by industrial cluster and supply-chain tier. What remains is a list of manufacturing factories with genuine points of entry. Walk down from vehicle assembler to component supplier one tier at a time: every tier further down means fewer factories to contact, more precisely defined procurement needs, and a lower threshold for the conversation — with the right direction set, the cost per closed deal finally comes down.
