Explore our primary array of high-precision components, machinery, and cycling inventory manufactured under strict ISO9001 quality frameworks.
Founded in 2005, VETOR GROUP has emerged as a premium B2B foreign trade enterprise specializing in high-performance machinery, vehicle components, and mountain bikes. Situated strategically in Cixi City, Zhejiang Province, our manufacturing plants occupy a central location along the fertile Hangzhou Bay. This spatial node gives us an exceptional logistical footprint: we are within 90 minutes of both Ningbo Port and Shanghai Port, and have immediate accessibility to major international hubs like Hangzhou Xiaoshan and Ningbo Lishe airports.
Over nearly two decades, VETOR GROUP has balanced standard parts production with custom engineering solutions. Our product matrix spans specialized deep-groove ball bearings, automotive assemblies, power generation systems, motorcycle internals, and high-performance bicycles. All production processes align with the ISO9001:2015 International Quality Management System, guaranteeing rigorous quality control from physical metallurgy inputs to load-bearing component testing.
In the global cycling industry, wheel size dynamics have undergone significant transitions. For decades, the 26-inch standard dominated the market, followed by the introduction of 29ers. However, the modern enterprise market has increasingly gravitated toward the 27.5-inch (650B) aluminum mountain bike as the optimal solution for diverse trail applications. This specific platform combines the acceleration dynamics and stiffness of smaller wheelbases with the roll-over ability, traction, and obstacle-clearance benefits of larger 29-inch wheels.
For B2B buyers and commercial distributors, importing 27.5" aluminum models represents a strategic portfolio decision. This sizing addresses a broader demographic range of riders who find 29ers too heavy or geometrically unwieldy, while still delivering significant competitive performance gains over legacy 26-inch models. Structurally, 27.5" frame designs allow for shorter chainstays, resulting in tighter handling and a stiffer rear triangle. This is particularly beneficial for aluminum frame applications where minimizing material mass while maintaining fatigue resistance is key.
An engineering deep-dive into alloy treatments, tube profiling, stress analysis, and structural performance.
We source structural-grade 6061 and 7005 aluminum alloys. Applying a multi-stage T6 thermal precipitation hardening treatment (artificial aging) increases yield strength, maximizing fatigue resistance for high-load off-road environments.
By using high-pressure hydraulic fluid to shape tubes inside steel molds, we vary tube wall thickness (double-butted and triple-butted processes). This puts material only where structural load demands it, lowering frame weight without sacrificing strength.
Our automated double-pass TIG welding processes prevent localized stress concentrations at tube intersections. Weld beads are meticulously smoothed and tested via Finite Element Analysis (FEA) to eliminate micro-cracks under dynamic loads.
Internal cable and hydraulic hose routing protects systems from trail debris, mud, and water ingress. This design also leaves ample structural space for integrated battery compartments for modern e-MTB variants.
VETOR GROUP operates on a Factory 4.0 lean manufacturing layout, integrating CNC milling, automated welding workstations, and standardized coating application systems. By digitalizing our production flow, we reduce lead times while improving structural tolerances on frame geometry, bottom brackets, and head tubes.
This internal integration directly benefits B2B procurement managers. Because we manage manufacturing processes from alloy extrusion processing to custom surface treatments, we maintain tight control over delivery schedules and material quality. Our location in Cixi City puts us at the center of China’s major component supply chains, ensuring direct access to specialty raw materials, precision gearing, and hydraulic brake components, helping shield buyers from unexpected supply disruptions.

VETOR GROUP serves global distributors, volume wholesalers, and specialized OEM brands. Understanding that different target demographics require tailored geometries and components, we offer custom design solutions to fit specific market segments:
OEM and ODM Frameworks: We provide full development cycles for custom frame design, custom tubing profiles, and frame geometry adjustments, with rapid prototyping options in 7–10 days. We also offer tailored paint schemes and decals to match brand requirements. By offering flexible component specification sheets—from entry-level gearing to professional hydraulic and suspension systems—we help clients balance cost with performance to optimize retail pricing.
Sourcing light vehicles and precision components globally requires careful navigation of regional regulations, safety standards, and customs duties. At VETOR GROUP, we help simplify this process by ensuring our products meet relevant safety benchmarks and international compliance standards.
Regulatory Alignment & Standards: Our manufacturing systems and components comply with ISO 4210 (safety requirements for city, trekking, young adult, mountain, and racing bicycles). Every bicycle and performance component is tested for impact performance, fatigue resistance, and overall structural integrity under simulated load conditions. We also supply necessary documentation to help streamline customs clearance and mitigate tariff challenges in various import regions.
A key structural advantage of VETOR GROUP’s bicycles and automotive components is our in-house bearing division. We manufacture high-precision deep groove ball bearings and EMQ (Electric Motor Quality) grade bearings, with inner ring dimensions ranging from 6mm to 90mm.
These bearings are engineered for low noise, low vibration, and reduced friction. By controlling bearing production internally, we can supply specialized hub and bottom bracket configurations that improve overall rolling efficiency and service life. These components are also used across a wide range of industries, including home appliances, electric motors, motorcycles, and agricultural machinery, serving customers throughout Europe, South America, and the Middle East.
Our operations adhere to ISO9001 quality management guidelines, ensuring traceable material quality and manufacturing safety.
We regularly present our mechanical and manufacturing technologies at international automotive and sporting goods exhibitions.
Beyond mountain biking assemblies, VETOR GROUP supplies a diverse selection of automotive and motorized parts.
EMQ deep groove ball bearings (6mm-90mm) engineered for low noise, vibration, and friction. Ideal for electric appliances, motors, and vehicle hubs.
Engine components, cylinder linings, drive assemblies, and brake pads conforming to OEM safety and dimensions.
