Folding Bike TPU Inner Tubes

Ultralight, Compact & Puncture-Resistant Solutions for Brompton & 20" Folding Bikes

Austrian Engineering for Urban Mobility

Next-Generation TPU Technology for Folding Bike OEM & Wholesale Partners

Modern urban commuters and folding bike enthusiasts demand maximum reliability with minimum carry weight. Engineered and tested in Austria, Tubolito replaces outdated butyl rubber with advanced Thermoplastic Polyurethane (TPU). The result is an ultra-durable folding bike tube that cuts rotating mass by up to 60%, shrinks packed volume to pocket size, and delivers superior puncture defense for daily city riding.

Folding Bike TPU Tubes FAQ

What makes Tubo-Folding ideal for Brompton and folding bike commuters?
Tubo-Folding reduces total wheel weight by up to 60% compared to standard butyl tubes. Its ultra-compact pack size fits easily into small frame bags or jersey pockets, making it the ideal low-weight spare and primary tube for folded bike transit.
Are Tubo-Folding TPU inner tubes compatible with rim and disc brakes?
Yes. Tubo-Folding tubes are thoroughly tested and fully approved for use with both rim brakes and disc brakes on 16-inch and 20-inch folding bicycles.
What size options and valve configurations are available for bulk B2B procurement?
Tubo-Folding is available in 16-inch (suitable for Brompton 1 1/8" - 1 3/8" width) and 20-inch (1.2" - 1.8" width) sizes. Both sizes are offered with Presta (SV 42mm) and Schrader (AV 40mm) valve stems to support diverse international retail specifications.
How should TPU inner tubes be inflated safely?
Tubolito TPU tubes must not be inflated above 0.5 bar / 7 psi when outside of the tyre. Over-inflation outside the tyre can cause permanent deformation and structural damage. Always follow max pressure guidelines printed on the outer tyre.
