Who We Are

PermeantsBikes is a professional carbon fiber bicycle frame manufacturer specializing in the design, development, and production of high-performance road, mountain, and gravel bike frames. Based in Huizhou, Guangdong Province, China, we bring together advanced carbon fiber engineering and a deep passion for cycling to deliver frames that meet the demands of riders and brands worldwide.

Since our founding in 2007, we have built a complete in-house manufacturing capability — from carbon layup and autoclave curing to custom painting and global logistics. Every step of the process is handled under one roof, ensuring full control over quality, consistency, and lead times.

We are not a trading company. We are builders, engineers, and cyclists who understand what a great frame needs to be. With over 15 years of experience in the carbon bicycle industry and more than 30,000 framesets exported worldwide, PermeantsBikes is a trusted manufacturing partner for cycling brands across the globe.


Manufacturing & Quality

Integrated production from carbon layup to final inspection

R&D and Design

Our in-house engineering team specializes in carbon layup optimization, aerodynamic tube profiling, and custom geometry development. Every frame is designed using FEA (Finite Element Analysis) to balance stiffness, weight, and ride comfort — ensuring each model meets its intended performance target.

Carbon Layup & Curing

We use premium Toray carbon fiber — including T700, T800, and T1000 grades — with precision hand layup and autoclave curing. Our EPS (Expanded Polystyrene) molding technology ensures smooth internal surfaces and consistent wall thickness across every frame, eliminating voids and imperfections that compromise strength.

Quality Control

Every frame is tested to 1.3× the ISO 4210 safety standard, exceeding international requirements. We perform stiffness testing, impact testing, and fatigue cycling on every production batch. Each individual frame undergoes visual and dimensional inspection before packing to ensure zero-defect delivery.

Custom Painting

Our professional painting workshop offers full custom paint service — any RAL or Pantone color, custom decals, matte or gloss finish. Your brand identity, perfectly executed on every frame.

OEM & ODM Services

Whether you need a proven platform with your branding (OEM) or a fully custom frame design from scratch (ODM), we support both models with flexible MOQ. From geometry and layup schedules to paint and packaging — every project is tailored to your specifications.


Our Flagship: The ST-09

The Permeants ST-09 represents the pinnacle of our engineering capability — a monocoque carbon road frame with no bonding points, weighing just 650g for the frame and 320g for the fork. Designed for riders who demand the absolute lightest weight without compromising stiffness or durability.

Our Mission

Deliver frames that perform at the highest level — with zero compromise on safety, quality, or ride feel.

We believe that every rider deserves a frame that is engineered with intention, built with precision, and tested to exceed international standards. Whether you are a brand launching your first product line or an established distributor seeking a reliable manufacturing partner, PermeantsBikes is built to support your growth.
