The E-bike market is defined by battery safety and drive-train reliability. We help global B2B importers and mobility brands source City, Mountain (e-MTB), and Fat-tire E-bikes from China’s leading manufacturing clusters. We focus on the technical integration—system compatibility, frame stress tests, and cell-level battery audits—ensuring your fleet performs in the real world.
Navigating China’s E-bike Clusters: Jinhua, Changzhou, & Shenzhen
E-bike sourcing is not “one size fits all.” We match your project to the specific strengths of China’s industrial regions:
- Jinhua & Yongkang (Zhejiang): The hub for high-volume, cost-effective E-bikes and folding models. Perfect for mass-market retail and entry-level brands.
- Changzhou & Kunshan (Jiangsu): The center for premium E-bikes and mid-drive systems. This region has deep roots in traditional bicycle manufacturing, offering superior frame geometry and assembly precision.
- Shenzhen & Dongguan (Guangdong): The leader in Smart E-bikes and high-tech components. Ideal for sourcing advanced controllers, IoT-integrated displays, and high-performance battery packs.
Technical Compliance & Safety: Beyond the Glossy Paint
For B2B buyers, a failed inspection or a battery fire can ruin a brand. We help you navigate these critical risks:
- Battery Cell Fraud: Many factories use unbranded or “Grade B” cells to lower costs. We verify the use of Samsung, LG, or high-tier Chinese brands (EVE/Bak) with cell-level testing.
- Motor Overheating: Inconsistent torque and poor heat dissipation in hub motors. We perform continuous load tests to ensure the motor meets its rated power.
- Frame Fatigue: Inexpensive frames may crack at the weld points under the extra weight of the motor. We audit the T4/T6 heat treatment process.
- Regulatory Compliance: Ensuring the pedal-assist (PAS) logic and speed limits comply with EN15194 (EU) or UL 2849 (USA) for legal road use and insurance.
Electric Mobility Solutions We Manage
Urban & Commuter E-bikes: Step-through frames with reliable hub motors for daily city use.
Electric Mountain Bikes (e-MTB): Mid-drive motor systems with integrated down-tube batteries and hydraulic suspension.
Fat-Tire & Off-road: High-torque 750W-1000W models for sand and snow terrains.
Cargo & Delivery E-bikes: Reinforced frames designed for heavy-duty commercial logistics.
Custom OEM/ODM: Managing custom frame geometry, private label branding, and specialized component selection (Shimano/Bafang/Suntour).
Our Hardcore E-bike Inspection Protocol
Battery Discharge Test: Running full-cycle discharge tests to verify actual Ah capacity and BMS (Battery Management System) shut-off safety.
Waterproofness Check: Testing the wiring harness and connectors for IP65/IP67 water resistance—critical for all-weather use.
Torque & Braking Test: Measuring stopping distances with weighted bikes to ensure hydraulic or mechanical brakes are properly tuned.
Component Verification: Physically checking that the derailleurs, tires, and forks match the exact specs in the proforma invoice.
Dangerous Goods Logistics: Managing the complex shipping requirements for Class 9 Lithium Batteries, ensuring all UN38.3 and MSDS documentation is correct.

FAQ
Q: Can you help us obtain EN15194 or UL certification? A: We work with manufacturers who already have these certifications. For custom designs, we coordinate with labs like TUV or SGS to manage the testing and certification process for your brand.
Q: What is the typical MOQ for custom branded E-bikes? A: For standard frames with custom colors/logos, MOQs usually start at 50 units. For fully custom frame geometry, the MOQ is typically 200–500 units.
Q: How do you handle warranty and spare parts? A: We negotiate a 1-2% spare parts kit (controllers, displays, throttles) to be included in the container. For major components like motors or batteries, we manage the factory’s warranty replacement process for you.
