Twelve thousand square metres in Guangzhou

Everything here is our own. The range, the tooling, the specification and the drawings are held in-house, and the whole of it is produced at our plant in Guangzhou — moulding, CNC, finishing, assembly and packing on the same site. That is what lets us quote a single piece and a container load from the same price list.

Who we are

A specialist in one category

Guangzhou Qiwo Intelligent Technology Co., Ltd. designs, manufactures and exports empty e-bike battery housings and conversion kits under its own ALX brand — 71 models across six fitments, from one piece, documented in English down to the internal envelope. Mechanical parts, and nothing electrical. Cells, BMS, motors and controllers we neither make nor certify — but we will source them on request and ship them with your order, as separate line items under the original maker's certification. Narrow focus is why we can hold a one-piece minimum and a fifteen-day lead time at the same time.

Our range covers Hailong, Silver Fish, integrated in-frame, downtube, rear rack and bottle-mount empty e-bike battery housings, compatible with 36 V to 72 V systems and 18650 or 21700 cells. Housings are moulded from ABS and aluminium alloy for impact and shock resistance, in a 12,000 m² facility running ten Haitian injection moulding machines and fifteen CNC machines.

Every case is sold as an empty shell, with selectable cable-exit positions and mounting options. We do not supply cells, BMS or finished packs. That boundary is deliberate: it keeps your product liability for the electrical assembly with you, and it keeps our engineering focused on the part we are actually good at.

Empty shells only. Cells, BMS, harness and pack assembly are yours. Tell us the cells and we confirm the envelope.
Both material families in house. ABS and ABS+PC injection moulding alongside aluminium alloy work.
One piece or millions. The same machinery runs your sample and your production order.

Inside the plant

Not stock photography — this is the floor your order runs on

Ten Haitian injection moulding machines, fifteen CNC centres, finishing, assembly and packing. All on one 12,000 m² site in Guangzhou, which is why a one-piece sample and a two-million-set programme come out of the same building.

What we make

Two product lines, one factory

E-bike battery cases

The core business. Six fitment families — Hailong, Silver Fish, integrated in-frame, downtube, rear rack and bottle mount — in ABS, ABS+PC and aluminium alloy, from 36 V to 72 V.

E-bike conversion kits

Built-in housings and in-frame conversion kits for builders putting a pack inside a frame that was never designed for one, including complete-vehicle support on special-dimension projects.

Conversion housings

Who buys from us

Battery assemblers who build packs and want the mechanical part from a specialist rather than tooling it themselves.
E-bike brands needing a branded shell that fits a frame they already sell, in their colour and with their logo.

Repair and upgrade workshops replacing failed or cracked housings on existing bikes — usually single-digit quantities, which is fine.
Distributors holding stock across several fitments and consolidating them into one shipment.

Quality

What we control, and what we will not claim

We would rather draw the line clearly than imply coverage that falls apart at a customs desk or in a customer complaint.

SHELL

Structure and impact

Housings are moulded from ABS and aluminium alloy for impact and shock resistance. Models specified as shockproof or vibration-tested carry those properties as part of their specification — ask about the specific model and we will confirm what applies.

WEATHER

Water and fire behaviour

Waterproof construction is a design feature across all 6 families, and flame-retardant grades are available on some models. If your market requires a stated ingress-protection rating, tell us the requirement and we will confirm in writing whether the model you are looking at is tested to it.

PRODUCTION

Consistency across batches

Runs follow documented quality-control procedures, with inspection through the production cycle rather than only at the end, so a batch that drifts is caught before it ships rather than after it reaches your warehouse.

Documents

Tell us which model you are considering and we will tell you exactly which drawings, material data and test reports exist for it — and which do not. We would rather answer that question honestly up front than discover the gap when your customer asks.

What is not ours to certify

Because we supply the housing and not the finished electrical assembly, certification covering the complete pack — UN38.3 transport testing, IEC 62133, EN 15194 and UL 2849 in the United States — belongs to the cell and BMS supplier and to whoever assembles the finished pack.

We will supply the housing-level inputs those files need and tell you plainly where our scope ends.

Export markets

Shipping to five continents

North America, Europe, Asia, Africa and South America. Named destinations include the United States, Turkey, India, Lithuania, Spain, Serbia, South Africa and Bolivia.

North America & Europe

United States, Lithuania, Spain and Serbia among our regular destinations — mostly OEM brands and battery assemblers building to their own pack specification.

Asia & Africa

Turkey, India and South Africa. A mix of distributors, conversion-kit sellers and repair networks who re-order the same handful of part numbers.

South America

Bolivia and neighbours. Generally distributor orders with consolidated shipments across several models at once.

How we work with overseas buyers

Quoted within five hours, in English, with the technical detail rather than just a price.
One-piece orders welcome. Plenty of our first orders from a new market are a single case.

NDA as standard on drawings, colour formulations and tooling.
