Bike Front/Rear Hubs Factory

Hub Range and Application Fit

From Road Bike Hub models with lightweight alloy shells and straight-pull spoke flanges to utility coaster hubs, each family has its own engineering focus. The table summarizes our range and typical application fit for the complete front/rear hub program.

Front hubs are the bearing and steering interface; rear hubs add the freehub body, cassette interface and ratchet drive. Depending on transmission principle, we build single-speed, derailleur-compatible and internal gear hubs.

For electric-assist platforms, our Custom Electric Bicycle Hub Suppliers line uses thru-axle and dual-cartridge bearing configurations to handle the higher torque of e-bike systems.

Manufacturing and Process Control

We keep core processes in-house because hub quality depends on coordination between forming, machining, surface treatment and assembly. Our chain includes punching, aluminum forging, CNC machining, cold forging, blackening and phosphating, aluminum oxidation, CP and ED plating, heat treatment and assembly.

Automation is applied to punching, CNC machining, hub assembly and freewheel assembly. This reduces manual variation and keeps key process parameters stable from sample approval through long production runs.

• Production base: 80,000 m² in Ningbo, China
• Annual hub output: 15 million pairs of steel hubs
• Annual freewheel output: 5 million pieces
• Monthly supply capacity: 1.3 million components

This integrated model is why global component brands work with us as a front/rear hub supplier for repeatable, volume-driven programs.

Materials, Construction and Surface Finish

Steel hubs give strength and wear resistance, which suits city bikes, shared fleets and heavy-duty use. Aluminum alloy hubs are lighter with higher rigidity and better corrosion resistance, making them the preferred choice for road, mountain and performance programs.

• Steel hub finishes: blackening, phosphating, CP plating, ED coating
• Aluminum hub finishes: anodizing, electrophoresis, plating
• Branding: laser marking or logo engraving on the hub body
• Custom colors and appearance options managed for batch consistency

Critical Specifications and Configuration

Every hub quotation starts with the same engineering variables. We configure the axle system, brake interface, spoke pattern, drivetrain and sealing level to match the completed wheel build.

• Axle: quick-release or thru-axle, diameter and frame spacing/OLD
• Brake interface: rim, six-bolt disc, center-lock disc
• Spoke specification: hole count, flange geometry, straight-pull or j-bend
• Drivetrain: cassette speed and brand, single-speed, fixed, coaster, internal gear
• Bearings and seals: sealed cartridge or serviceable ball, with sealing level matched to riding environment
• Rear engagement: ratchet, planetary gear, internal spline engagement

OEM/ODM and Customization Path

Our OEM/ODM projects follow a defined path: manufacturing feasibility review, sample development aligned with mass production conditions, specification lock, and batch production with process consistency verification. Confirmed samples therefore represent production output, not isolated prototypes.

Customization is supported in areas that can be controlled and scaled:

• Hub body dimensions aligned with different frame standards
• Axle standards and spacing configurations
• Hole count and flange geometry adjustments
• Bearing configuration options
• Material selection, surface finish and color
• Laser marking, private label and OEM packaging

Quality, Verification and Warranty

Quality control runs through raw material preparation, processing, surface treatment, assembly and final inspection. Our focus is reducing batch variation through process control rather than relying on final sorting.

• Dimensional and assembly accuracy inspection
• Functional performance verification
• Structural load and durability evaluation based on application
• Surface treatment consistency and corrosion resistance testing

The standard warranty is 2 years for manufacturing or material defects under normal use. Warranty support follows problem confirmation, technical evaluation based on production data, and correction or replacement according to liability attribution.

Information We Use to Configure Your Solution

We prepare each hub proposal from these inputs. The more exactly the inputs match the final wheel build, the shorter the review cycle.

• Bicycle platform, wheel size and front/rear position
• Axle standard, diameter and frame spacing/OLD
• Brake type and rotor mounting standard
• Spoke count, flange drill and straight-pull/j-bend requirement
• Cassette speed and brand, or single-speed/fixed/coaster requirement
• Material, target weight, finish and color
• Bearing and sealing requirements for the riding environment
• Forecast volume, packaging and logistics target

Frequently Asked Questions

What is the difference between a front hub and a rear hub?

A front hub carries the bearing and steering load and connects to the fork. A rear hub adds the freehub body, cassette interface and ratchet or planetary engagement, and may integrate internal gears or a coaster brake. We manufacture both as matched front/rear pairs.

Which disc brake standards do your hubs support?

Our hub range includes six-bolt and center-lock disc interfaces, plus rim brake and coaster brake variants depending on the hub family. The brake standard is confirmed during the configuration review.

Can you produce hubs for high-torque e-bikes?

Yes. Our e-bike hub line uses thru-axle and dual-cartridge bearing designs to support the higher torque of electric-assist systems. We review motor type, axle specification and torque requirements when preparing the proposal.

How do you ensure samples match mass production?

Sample development is aligned with production conditions, and specifications are locked before scaling. Process parameters are monitored with inspection checkpoints and batch traceability so confirmed samples represent ongoing production quality.

What maintenance should be planned for your hubs?

Bearings and freehub bodies are designed as serviceable modules. Specialized tools allow replacement without replacing the complete hub. Sealing levels are matched to the intended environment to extend service intervals.

Do you supply hubs only or complete wheelsets?

We supply hubs individually and as part of complete wheel programs. Review our Wheelset range for factory-built front and rear wheel configurations matched to the same production standards.
