Direct factory wholesale, scalable OEM customization, and ultra-lightweight high-tenacity tube formulations exported to 50+ countries worldwide.
As China's leading OEM/ODM manufacturer and exporter of bicycle inner tubes, we bridge Austrian precision polymer engineering with state-of-the-art Chinese high-capacity automated extrusion facilities.
For over a century, vulcanized synthetic butyl rubber served as the undisputed standard for pneumatic bicycle inner tubes. However, as modern cycling performance demands lower rolling resistance, decreased rotational inertia, and compact logistics profiles, butyl rubber has hit its physical limits. Traditional butyl inner tubes weigh between 100g to 150g per wheel for standard road applications and up to 300g for mountain bikes, while occupying significant volumetric space in retail packaging and transit containers.
By leveraging chemical breakthroughs in Thermoplastic Polyurethane (TPU) elastomer formulation, our Chinese manufacturing headquarters has successfully industrialized ultra-thin wall co-extrusion technology. TPU allows for wall thicknesses down to 0.15mm while simultaneously doubling the tensile strength and puncture threshold compared to standard butyl rubber.
From an international B2B buyer’s perspective, transitioning to OEM TPU tube inventory reduces ocean shipping freight volume by up to 70%, dramatically lowers customs tariff impact by cubic weight, and offers commercial brands an undeniable value proposition: professional race-grade weight savings at scalable wholesale price points.

Utilizes computer-controlled ring extrusion heads ensuring zero wall-thickness variance. Eliminates structural weak spots along the perimeter for uniform air mass distribution.
TPU's high elongation at break prevents sharp objects from piercing through immediately. The material stretches around thorns or glass before bursting, reducing explosive blowouts.
Removing up to 100 grams of rotational mass directly at the rim circumference offers equivalent kinetic energy savings to removing ~200 grams from the bike frame during acceleration and climbing.
Key strategic insights for importers, OEM bike brands, chain distributors, and e-commerce enterprise sellers preparing for the next decade of supply chain evolution.
Major European and North American bicycle brands are phasing out standard butyl inner tubes as stock equipment on mid-to-high tier road, gravel, and e-bikes. Equipping TPU tubes allows bike manufacturers to claim immediate 150g-200g weight reductions on complete bikes in retail showrooms without retooling expensive carbon frames or alloy wheelsets.
Strict European Union environmental mandates (such as the EU Corporate Sustainability Due Diligence Directive) are forcing distributors to evaluate product end-of-life options. Unlike vulcanized rubber which cannot be melted down, TPU is a true thermoplastic. Waste material and end-of-life tubes can be remelted, pelletized, and repurposed into tire levers, rim strips, or industrial bushings.
The convergence of smart electronics and cycling components has reached inner tube design. Future procurement cycles favor manufacturers capable of co-molding NFC micro-chips directly into TPU valve stems. This allows riders and mechanics to scan tire pressure directly via smartphone apps without attaching mechanical pressure gauges.
With the explosive growth of urban e-cargo delivery fleets, inner tubes face unprecedented static loads and continuous torque. Chinese export manufacturing is shifting toward heavy-duty, extra-thick TPU formulations (such as X-TUBO technology) that provide flat-free reliability under 200kg gross vehicle weight.
