BikeTube

Heavy Duty eBike TPU Tube, 27.5x4.0-4.5", SV 35mm

The BikeTube Heavy Duty eBike TPU Tube is a lightweight, high-strength TPU inner tube built for 27.5" fat tires and the higher loads and speeds common with e-bikes, helping reduce rotating weight while maintaining dependable durability on trail, gravel, and pavement.

• 27.5 x 4.0–4.5" fit - Sized for modern fat-tire eBike and plus applications where a stable, properly matched tube matters for support and ride quality
• Double-thickness TPU construction - Designed for added toughness versus typical thin TPU tubes, targeting better real-world resistance to pinch and abrasion
• Lower rotating mass vs. butyl - TPU tubes are typically far lighter than standard butyl fat-bike tubes, improving acceleration and making the bike feel more responsive
• Efficient rolling feel - TPU’s material properties can reduce hysteresis losses compared to conventional rubber tubes, supporting a faster feel at a given tire pressure
• SV (Presta) 35mm valve - A practical valve length for many fat-bike rims while keeping a clean, secure fit at the valve hole
• Service kit included - Comes with 2 alcohol prep pads and 2 patches to support proper cleaning and repair when a trail-side fix is needed
