Custom Carbon Fiber Bike Parts for OEM/ODM Projects

Carbon Fiber Bike Components We Manufacture

We manufacture custom carbon fiber parts used in bicycles, e-bikes and cycling equipment. We do not focus on retail sales of complete standard bicycles. Instead, we support OEM and ODM carbon fiber bicycle components, including frame sections, forks, handlebars, fenders, guards, e-bike covers and custom lightweight structural parts.

For clients developing complete carbon fiber bikes, we can also provide reference models, component integration support and manufacturing evaluation based on your target weight, riding scenario, market positioning and budget.

We are not a retailer. We are a composite material manufacturing factory — not only a bicycle frame supplier, but a custom carbon fiber composite manufacturer for bicycle, e-bike and sports equipment projects. Our long-term experience across automotive, motorcycle, sports and industrial carbon fiber sectors is applied to bicycle component manufacturing for B2B clients across Europe, North America, Australia, Southeast Asia and the Middle East.

Carbon Fiber Bicycle Parts We Manufacture

We support a wide range of carbon fiber bicycle components. Below is an overview of what we currently manufacture for OEM and ODM clients:

We do not supply standard open-mold frames under shared tooling. Every product we manufacture is custom-produced for each client’s specific project.

For safety-critical parts such as forks, handlebars, rims and load-bearing frame structures, final production is based on confirmed drawings, structural requirements and third-party testing where required by the target market.

Complete Carbon Fiber Bicycle Reference Models

In addition to custom carbon fiber bicycle parts, we also use complete lightweight bicycle reference models to help OEM and ODM clients evaluate frame structure, component matching, surface finish, packaging and market positioning.

These reference models are not fixed retail products. They are used to support technical discussion for clients who want to develop carbon fiber bicycles, lightweight cycling products or custom carbon bike components. For a broader overview of how carbon fiber is used across different bicycle types and components, see our Carbon Fiber Bicycle Guide.

(Reference model images available on request. Contact us for product photos, weight records and configuration details.)

Final specifications can be adjusted according to the client’s target market, budget, riding scenario, certification requirement and brand positioning.

OEM Project Options for Carbon Fiber Bikes and Components

We support a range of B2B project types, from individual custom parts to complete bicycle concept development:

함께 일하는 사람

Our carbon fiber bicycle parts are manufactured for:

• Bike brands and private label companies looking to develop unique carbon components without building their own factory
• E-bike manufacturers and integrators who need lightweight carbon covers, guards and structural housings
• Racing teams and sport performance companies developing custom carbon fiber bicycle frames and components
• Repair and aftermarket businesses needing replacement parts or upgraded carbon fiber alternatives to OEM plastic or aluminum components
• Product developers and startups who have a design concept and need manufacturing support from prototype to production

Example: How a Lightweight Carbon Fiber Bicycle Is Built

A complete lightweight carbon fiber bicycle project is not only about the frame. The final riding experience depends on the integration of frame geometry, fork stiffness, handlebar position, wheel selection, drivetrain compatibility, brake system, surface finishing and packaging.

Based on our reference bicycle projects, a typical lightweight carbon fiber bicycle development may include:

This system-level view helps clients understand how each component decision affects the overall project, and where carbon fiber manufacturing choices matter most.

Customizable Specification Options

For OEM and ODM bicycle projects, specifications can be adjusted according to the client’s brand positioning and target market:

Carbon Fiber Materials for Bicycle Parts

We work with the following carbon fiber materials, selected based on the structural requirement, surface appearance, weight target and budget of each project:

Material grade, lot reference and cure date are documented per project. We can use Toray-origin prepreg when required and available, or Japan / Taiwan / China-origin equivalent prepreg based on the project budget and certification requirement.

The same material selection process we use for bicycle parts applies across our other product sectors. Clients with cross-industry projects can also explore our work in 탄소 섬유 자동차 부품 그리고 탄소 섬유 모터사이클 부품, where similar material grades and processes are used in demanding structural and aesthetic applications.

Manufacturing Processes for Carbon Fiber Bicycle Parts

Different bicycle components require different manufacturing processes. We select the process based on geometry, wall thickness, structural load, batch size and surface finish requirement.

Prepreg Molding — Most Common for Structural Bicycle Parts

Prepreg (pre-impregnated carbon fiber sheets) is our primary process for bicycle forks, handlebars and frame sections. Carbon fiber is pre-impregnated with epoxy resin under controlled factory conditions, then laid into precision tooling and cured under controlled temperature and pressure.

최적 대상: carbon fiber bicycle forks, frame sections, high-load structural components Advantage: Best fiber-to-resin ratio, highest strength-to-weight, consistent surface quality 한정: Higher tooling cost, requires controlled material storage and temperature management

Bladder Molding — For Hollow Bicycle Tubes and Bars

An inflatable bladder is placed inside the carbon fiber layup. During curing, internal pressure consolidates the carbon against the mold wall, creating a hollow structure with consistent wall thickness.

최적 대상: carbon fiber handlebars, seatposts, hollow frame tubes Advantage: Clean hollow internal surface, good pressure consolidation, compatible with complex tube profiles 한정: Bladder removal path must be designed into the part geometry from the start

Compression Molding — For Batch Accessories and Covers

Carbon fiber mat or short-fiber prepreg is placed in matched metal tooling and pressed under heat and pressure.

최적 대상: carbon fiber bicycle fenders, guards, covers, small brackets, chain guards Advantage: Stable batch production, good repeatability, lower per-part cost at volume 한정: Less suitable for large hollow frames or complex 3D structural tube sections

Resin Infusion / Wet Layup — For Low-Volume or Large Covers

Dry carbon fiber fabric is placed in a mold and resin is applied under vacuum or by hand.

최적 대상: Large e-bike body covers, fairings, protective housings where weight is secondary to cost Advantage: 대형 또는 단일 곡률 부품 프로토타입 제작에 적합한 낮은 금형 투자 한정: Higher part weight versus prepreg, less consistent fiber ratio across batch

CNC Carbon Fiber Plate — For Flat Brackets and Panels

Flat carbon fiber sheets are CNC-machined to the required shape. No mold required.

최적 대상: Flat mounting brackets, stiffening plates, frame reinforcement inserts, custom flat components Advantage: Fast development, no mold cost, tight dimensional tolerances 한정: Not suitable for complex 3D frame geometry or hollow tube sections

Open Mold vs Custom Mold vs Reverse Engineering: Which Is Right for Your Bicycle Part?

When open mold makes sense: You are launching a new bike brand with limited budget and need a functional product quickly. You can differentiate through components, finish and branding rather than frame geometry.

When custom mold makes sense: You have a unique geometry, a proprietary design, or a component that does not exist in any current catalog. You want full design ownership and exclusive tooling.

When reverse engineering makes sense: You have an existing plastic or aluminum part and want to replace it with a carbon fiber version — or you need to reproduce a part where no digital files exist. We work from the physical sample to create mold geometry.

Lightweight Is Important, But Safety Comes First

Many carbon fiber bicycle projects begin with a target weight. However, weight alone is not enough to define a good carbon fiber bicycle part.

For B2B manufacturing, we review each part based on its real function: whether it is cosmetic, protective, semi-structural or safety-critical. A lightweight carbon frame section, fork, handlebar or seatpost must still meet the required stiffness, fatigue resistance, insert strength and long-term durability for its intended use.

Before reducing weight in any structural bicycle component, we check:

• Rider load and expected use environment
• Whether the part carries steering, braking or frame load
• Wall thickness and layup consistency
• Local reinforcement around mounting holes, clamps and inserts
• 피로 및 충격 테스트 요구 사항
• Whether ISO 4210 or EN 15194 testing is needed for the target market

Our goal is not simply to make a carbon fiber part lighter. Our goal is to make it lighter, manufacturable and suitable for its intended use.

Carbon Fiber Bicycle Part Development: What We Check Before Starting

This checklist reflects real engineering questions we go through before committing to a development timeline and tooling cost.

Structural classification:

• Is this part structural (carries rider or drive load) or cosmetic (appearance and protection only)?
• Does it connect to a safety-critical system such as steering, braking or frame integrity?
• Are there metal inserts, bonded joints or threaded interfaces?

Manufacturing feasibility:

• Is the hollow structure designed to allow bladder removal after curing?
• Are there sufficient draft angles on all mold faces for clean demolding?
• Are wall thickness requirements consistent with the chosen carbon fiber process?
• Are there undercut areas that require split tooling or multi-part molds?

Testing and compliance:

• Does the target market require ISO 4210 (bicycle safety) or EN 15194 (e-bike) compliance?
• Is fatigue testing required for the specific load cycle of this part?
• Are there mounting point pull-out or torque requirements to meet?

표면 및 마감:

• Is the visible surface cosmetic carbon (3K twill or UD) or painted?
• Is a Class-A surface finish required, or is a functional finish acceptable?
• Are logo, decal or masking details needed?

Custom Carbon Fiber E-Bike Parts

The e-bike sector creates specific demand for carbon fiber parts that go beyond traditional bicycle components. We manufacture the following for e-bike brands and integrators:

• Carbon fiber battery covers and housings — lightweight shells replacing plastic OEM covers, maintaining original mounting geometry
• Carbon fiber motor covers and guards — protective and aesthetic covers for mid-drive and hub motor systems
• Carbon fiber frame panels and inserts — lightweight cosmetic covers integrated into e-bike frame structures
• Carbon fiber racks and cargo structures — lightweight rear racks and mounting systems for cargo e-bikes
• Carbon fiber chain guards and protection covers — lightweight guards for belt-drive and chain systems

For e-bike components connected to electrical systems, we manufacture the carbon fiber structural and cosmetic shell only. Electrical integration, waterproofing and EMI compliance are outside our manufacturing scope and remain the client’s responsibility.

OEM and ODM Carbon Fiber Bicycle Parts Service

우리는 OEM 및 ODM 제조 관계를 모두 지원합니다.

OEM (Original Equipment Manufacturing): You provide STEP/STP files, 2D drawings or physical samples. We manufacture to your specification. You own the design. Mold tooling belongs to your project.

Quality Control for Carbon Fiber Bicycle Parts

Our quality process covers the full production cycle:

• Raw material batch record: prepreg lot, cure date, storage temperature log
• Layup schedule control: ply count, orientation and material checked per job card
• Mold temperature and pressure curing records per batch
• Internal surface inspection for hollow parts after bladder removal
• Insert bonding inspection: pull-out test on sample basis
• Dimensional inspection against drawing or reference sample
• Visual inspection: surface defects, pinholes, delamination, fiber read-through
• Final inspection before packing: part number, finish, logo, packaging condition

On testing standards: For bicycle frames, forks and handlebars targeting regulated markets, we can coordinate third-party testing to ISO 4210 (cycles — safety requirements for bicycles) or EN 15194 (e-bikes) based on the client’s target market and compliance requirements. We do not claim parts are pre-certified to ISO 4210 unless that specific project has completed the required testing process.

Typical Lead Time and Tooling Cost Factors

We do not publish fixed price lists because every custom carbon fiber bicycle part project is different. The following factors determine both tooling cost and production lead time:

Factors that affect tooling cost:

• Part size and overall dimensions
• Mold material required (aluminum for mid-volume, steel for high-volume)
• Number of mold split lines and part complexity
• Hollow or solid structure (bladder tooling adds cost)
• Insert and bonding interface requirements
• Cosmetic surface finish level required on the mold face

Factors that affect lead time:

• Whether existing tooling can be used or new molds must be fabricated
• Complexity of the layup schedule and number of plies
• Whether reverse engineering from a physical sample is required
• Number of prototype iterations needed before approval
• Testing requirements before batch production begins

As a general guide: simple parts using existing tooling can be produced in 2–3 weeks. New custom mold projects typically run 8–16 weeks from design freeze to first production sample, depending on complexity. We provide a project-specific schedule with every quotation.

FAQ: Custom Carbon Fiber Bicycle Parts

Can you manufacture custom carbon fiber bicycle parts from STEP files?

Yes. We can review STEP/STP or IGES files and assess geometry for carbon fiber manufacturing feasibility. This includes checking wall thickness, mold split lines, undercut areas, insert positions and suitable process selection. For load-bearing bicycle frames and forks targeting consumer markets, we recommend the client also arrange ISO 4210 third-party structural testing, which we can coordinate through partner testing laboratories.

Do you make open-mold carbon bike frames or only custom molds?

We focus primarily on custom-mold projects where clients have their own design or need engineering development. We do not maintain a catalog of open-mold frames for resale. If you are starting a bike brand with limited budget, we recommend beginning with custom components — fork, handlebar, fender, cover — where tooling cost is lower, before committing to a full custom frame mold.

What carbon fiber grades do you use for bicycle parts?

We work with T700 and T800 carbon fiber in unidirectional (UD) and woven (3K twill) formats as standard. Higher modulus grades are available on a project basis. We can use Toray-origin prepreg when required and available, or Japan / Taiwan / China-origin equivalent based on the project budget and certification requirement. Material grade, lot number and cure date are documented per project.

What is the MOQ for custom carbon fiber bicycle parts?

MOQ는 툴링이 이미 존재하는지 여부에 따라 달라집니다.

기존 금형을 사용하는 두 번째 실행의 경우 MOQ는 부품 복잡성에 따라 20~50개 정도로 낮을 수 있습니다.

새로운 맞춤형 금형 프로젝트의 경우 전체 생산량을 확정하기 전에 첫 번째 샘플 승인 후 30~100개의 파일럿 배치를 권장합니다.

우리는 각 특정 프로젝트를 기반으로 MOQ에 대해 논의합니다.

Yes. We manufacture carbon fiber battery covers, motor covers, frame guards, body panels, racks and custom lightweight housings for e-bike brands and integrators. We manufacture the carbon fiber structure only. Electrical integration, waterproofing and EMI compliance remain the client’s responsibility.

What surface finishes are available for carbon fiber bicycle parts?

Available finishes include: raw UD carbon, 3K twill carbon weave, matte clear coat, gloss clear coat, matte painted, gloss painted, custom Pantone or RAL color, two-tone finish, logo application by printed decal or painted mask, and textured finishes on request.

How long does a custom carbon fiber bicycle part project take?

A typical project runs: file review and quotation (3–5 days) → mold design and fabrication (3–6 weeks) → first sample production (1–2 weeks) → client review and approval → pilot batch (2–4 weeks) → mass production. Simple parts with existing molds can be produced in 2–3 weeks. Full custom projects with new tooling typically take 3–5 months from design freeze to first production batch.

Can you reverse-engineer a carbon fiber bicycle part from a physical sample?

Yes. If no 3D file is available, we can work from a physical sample or an OEM plastic reference part. We use 3D scanning or manual measurement to create mold geometry. This adds approximately 1–2 weeks to the project timeline and is reflected in the tooling cost estimate.

Do you offer private label packaging for carbon fiber bicycle parts?

Yes. We can provide parts in plain packaging, client-branded boxes, polybags with client labels or custom retail packaging. All project details are treated as confidential. NDA agreements are available at the client’s request.

Why Choose a Custom Carbon Fiber Parts Manufacturer Over a Standard Bicycle Frame Supplier

Most carbon bicycle suppliers in China offer a catalog of existing frame designs available under your brand name. This is a fast, low-cost route to a branded bike — but it comes with limitations: identical geometry to competitors, no structural IP, limited finish options and no engineering support for unique requirements.

We are not a catalog supplier. Our value is in manufacturing custom carbon fiber bicycle components that do not exist yet — parts that require geometry development, layup engineering, tooling design and quality-controlled production. You can see the full range of what we manufacture across industries on our 홈페이지.

This makes us the right manufacturing partner when:

• You need a carbon part that does not exist in any current open-mold catalog
• You have a unique bicycle design requiring custom mold tooling
• You need to replace a plastic or aluminum part with a carbon fiber equivalent
• You are developing an e-bike product requiring lightweight custom carbon housings
• You need a carbon fiber bicycle component manufactured to your brand and specification with exclusive tooling

If you need an existing frame design with your logo applied, there are faster and cheaper options. If you need something engineered and manufactured to your specific requirement, contact us.
