About Keyu Bag
One of the most dependable cycling bag manufacturers from China Waterproof bike bags — designed, cut and sewn in-house in Xiamen.
Keyu Bag is a professional manufacturer of cycling bags, built on the philosophy of its name — Ke for precision engineering, Yu for capability without limits — along with a dedicated sewing team and modern equipment to ensure your order runs successfully. Whether you need a custom OEM design developed from a sketch or a drawing, or your existing range produced at scale with consistent quality, Keyu Bag can assist with those needs.
🟧🟧🟧🟧🟧🟧🟧🟧
What does Keyu Bag do?
We began by making simple bags for local brands — and kept every lesson about stitching, hardware and waterproofing along the way.
Today Keyu Bag produces waterproof handlebar bags, top tube bags, saddle bags, pannier bags, bike backpacks and cycling wallets for brands, distributors and retailers across Europe, North America and Australia. One factory floor handles cutting, welding, sewing and packing, so quality stays in our own hands.
🟧🟧🟧🟧 By the numbers
A factory sized for consistent quality.
We measure the business by orders delivered on time, samples approved on the first pass, and buyers who come back with the next season's line.

🟧🟧🟧🟧 How we choose
The standards behind every bag we sew.
These principles shape how we quote, sample and produce — and why buyers stay with us season after season.

Reinforced where bags fail
Bartack stitching at every stress point — zipper ends, strap anchors — where cheaper bags tear first.

Your drawing, your logo, your hardware. We build to your spec instead of forcing a stock design.
