We provide a wide variety of bicycle tires with complete specifications, available in eight colors: red, orange, yellow, green, blue, white, gray and black. Our products cover everything from 12‑inch kids’ bike tires to 28‑inch heavy‑duty bicycle tires.

We own two major brands: Diamond and Qilun.

Diamond brand tires are a perfect combination of tradition and innovation. Since the 1950s, they have been exported to Southeast Asia, Africa and South America. We also supply original equipment to many well‑known domestic bicycle and electric vehicle manufacturers, enjoying a high reputation in both international and domestic markets.

As a rising star, Qilun brand tires have secured a place in the increasingly competitive domestic market with excellent product quality and high cost‑performance.
