We make frames — that is the origin of this business. Our Foshan plant has fabricated bicycle frames since 2014, running alloy welding, carbon layup and painting in-house, and we supply frames and forks to brands and assemblers on OEM terms.
What we make
Road, gravel, mountain (hardtail and full suspension) and children’s frames, in carbon fibre (T700, T800 and T1100 grades), aluminium 6061 and 7005, and steel. Forks, both rigid and suspension-compatible, and seatposts, cockpits and swingarms to match. Frames can be supplied finished and painted, or as raw sub-assemblies for your own paint line.
OEM means the specification is fixed before the first frame is built
The failure mode in frame supply is not bad workmanship, it is an undefined specification. A frame described as “carbon” or “aluminium butted” leaves room for a different fibre grade, a different layup schedule or a straight-gauge tube, and the difference does not show in a photograph. So we fix, in writing and before production:
- Material and layup — fibre grade, and for carbon, the layup schedule by zone.
- Wall thicknesses — by zone on butted tubing, or the table of thicknesses for the frame.
- Geometry and tolerances — head and seat angles, chainstay and top-tube lengths, bottom-bracket shell and threads, with the tolerance allowed on each.
- Finish — colour reference, decal artwork and the maximum tone difference allowed between frame and fork.
- Hardware — mounts, bosses, cable routing and dropout specification.
The first article of the production line is then measured against that sheet and approved before the rest of the batch is packed.
Testing and documentation
Sampled structural and fatigue testing to ISO 4210, seven QC checkpoints per order, and pre-shipment inspection with photographs and carton count. Frame weight is recorded per size and per batch, which is the single most useful measurement a brand can hold — it is the number most often quoted loosely and the one buyers check first.
Tooling and volumes
An existing mould has no tooling cost and carries the lowest minimum we offer. A private mould in high-modulus carbon with a bespoke finish requires substantially more volume, because tooling has to be amortised. Tell us whether you want a private mould or a platform frame and we will confirm both the tooling position and the exact minimum for that configuration.
Commercial terms
Standard wholesale terms are a 30% T/T deposit with the order and the balance against the B/L copy; L/C at sight is also accepted. Samples are available before volume commitment, and on OEM frame projects we recommend validating the sample against the tolerance sheet before production starts.
Frame specification sheet: what gets fixed in writing
| Item | What we record | Why it prevents disputes |
|---|---|---|
| Material and layup | Fibre grade (T700 / T800 / T1100) and, for carbon, the layup schedule by zone | “Carbon” alone permits a different fibre grade or a cheaper schedule |
| Wall thickness | Thickness by zone for butted tubing; the thickness table for the frame | A straight-gauge tube still matches a loose description |
| Geometry | Head and seat angle, chainstay and top-tube length, stack and reach by size | Small geometry changes alter how the bike rides and are invisible in photographs |
| Tolerances | Bottom-bracket shell and threads, head tube reaming, dropout spacing, face parallelism | These decide whether the frame can actually be assembled without rework |
| Finish | Colour reference, decal artwork, and the maximum tone difference allowed between frame and fork | Frame and fork are painted separately — a mismatch is visible on the shop floor |
| Weight | Recorded per size and per batch | It is the measurement buyers quote most loosely and check first |
| Hardware | Mounts, bosses, cable routing, dropout specification | Decides compatibility with the components the build actually uses |
The first article off the production line is measured against this sheet and approved before the rest of the batch is packed. On frame supply, that single step prevents most of the disputes that otherwise arrive with the container.
Container loading reference
| Configuration | Reference units per 40ft High Cube |
|---|---|
| 27.5″–29″ adult MTB, one unit per carton (≈85% assembled) | ≈360–430 |
| Same models, knocked down | Substantially more — typically 60–100% more, depending on carton design |
These are industry reference ranges, not commitments: the real figure follows your carton dimensions and assembly ratio, and we calculate it for your exact mix before you commit. Note that adult bikes are usually volume-limited rather than weight-limited — which is why knocking a bike down increases the count far more than shaving a kilogram off it.
What drives the minimum order quantity
MOQ in this trade is not arbitrary, and it is not a negotiating position. It comes from four things:
| Driver | Effect on MOQ |
|---|---|
| Tooling | An existing mould carries no tooling cost and allows the lowest quantity we offer. A private mould has to be amortised, so the minimum rises in step with the tooling cost. |
| Frame material | Alloy has the lowest barrier. Carbon adds layup tooling and a longer ramp, so the minimum rises again — more on a new layup than on an established one. |
| Finish complexity | Two-colour wet paint and custom decals require masking, artwork and a paint batch run; a single-colour powder coat does not. |
| Component availability | Named-brand groupsets have their own supply lead times and minimum purchase steps, which can set the floor for the whole order. |
Inside a mixed container, per-model and per-colour minimums apply as well. That is why a container built from four variants usually costs more per unit than the same volume built from two — the mix is a cost decision, not just a merchandising one.
The seven QC checkpoints every order passes
| # | Checkpoint | What is checked |
|---|---|---|
| 1 | Incoming material | Tube and sheet specification, alloy grade confirmation, and component references against the bill of materials |
| 2 | Frame dimensional | Critical dimensions and geometry against the tolerance sheet; bottom-bracket thread and facing |
| 3 | Weld and alignment | Weld quality, rear-triangle alignment, dropout parallelism, and fork alignment |
| 4 | Surface and paint | Surface preparation, primer and topcoat coverage, colour against the approved sample, decal position |
| 5 | Assembly and torque | Torque on critical fasteners, brake setup, gear indexing, and wheel trueing |
| 6 | Function test | 100% of units: braking, shifting, steering — and electrical function on e-bikes |
| 7 | Packing and loading | Carton contents against the packing list, carton count, and photographs of the loaded container before the doors close |
Structural and fatigue testing to ISO 4210 is carried out on sampled frames rather than on every unit. Sampling is the method the standard itself describes, which is why an inspection report containing the sample plan and the results is what a third-party inspector will ask for first.
Frequently asked questions
Do you supply frames without paint?
Yes. Frames can travel raw for your own paint line, or finished and painted here. Raw frames reduce cost but move the finish risk to your supplier — which is a deliberate trade, not an oversight.
What is the minimum for a private mould?
Tooling is the deciding number, so the minimum is quoted per project rather than published: a new private mould in high-modulus carbon with a bespoke finish requires materially more volume than an existing platform.
How is frame weight verified?
Frame weight is recorded per size and per batch during inspection, and the figure travels with the shipping documents. If weight is critical to your market, state the target on the tolerance sheet so it is checked rather than assumed.
Can you work from a reference frame we already own?
Yes. Reverse-engineering a sample is one of the most common starting points; it ends with a written specification and tolerance sheet that both sides agree before production.
What testing do you carry out?
Sampled structural and fatigue testing to ISO 4210, plus the seven checkpoints applied to every order and 100% pre-shipment function testing on assembled goods.
When we are not the right supplier
Two qualifications, stated plainly. First, if you need twenty units next week, we are not your supplier: there is no production run to release and no sea freight to catch, and local stock will beat us on speed every time. Second, factory-direct pricing only pays off when an order is planned. If you are assembling a range for a season, we work; if you are filling a gap in a single week, we do not.
What we will not do is quote you a specification we cannot hold. If a component in your target build is not available at the price point you need, we say so and offer the alternative rather than matching the quote and hoping the difference is not noticed on arrival.
