Why Partner with a Specialized Bike Component Factory?

Collaborating with an integrated specialist manufacturer delivers decisive advantages for your brand that a generic supply chain cannot match.

Engineering & Co-Design: We go beyond simple build-to-print. We provide end-to-end engineering partnership from concept to mass production. Our focus is on Design for Manufacturing (DFM), optimizing performance and lightweight design while controlling costs and enhancing production efficiency.

Vertical Integration & Full-Process Quality Control: From the selection of premium raw materials like 7075 aluminum alloy, through 3D forging, precision CNC machining, to final anodizing and packaging—all core processes are completed in our own factory. This vertically integrated model fundamentally ensures product consistency, ultra-short lead times, and uncompromising quality.

Flexible Scalability: Whether you are a startup needing small-batch prototypes to validate the market or an established brand seeking high-volume production, we provide matching flexible manufacturing solutions as the most reliable foundation for your growth.

Manufacturing Excellence: The Core Competencies of LUNJE

As your preferred bike component manufacturer, we leverage cutting-edge technology and market insight to build truly competitive products.

Advanced Materials & Forming Processes: We utilize aerospace-grade 7075 aluminum and form it with advanced 3D forging and drawing technology. This process optimizes the metal grain flow, creating exceptionally lightweight handlebars with superior fatigue resistance and impact strength, suitable for demanding disciplines from trail to racing.

High-Precision CNC Machining: All clamping surfaces, cable ports, and complex contours are machined on 5-axis CNC centers. The result is perfect tolerances, flawless finish, and 100% functional reliability.

Market Insight Rooted in Practice: Through close dialogue with hundreds of professional athletes and industry KOLs worldwide, we gather firsthand feedback. This allows us to pinpoint rider pain points and market trends, ensuring our OEM/ODM designs are not only eye-catching but offer practical value and commercial potential.
