ULIP Inner Tube 20x4.0 for Fafrees FF20 Polar

Model-oriented offer for Fafrees FF20 Polar, a foldable, homologated fast fat e-bike. The official EU website lists Chaoyang 20 × 4.0 tires and butyl inner tubes. The ULIP inner tube is therefore intended for replacement on a bike that still uses the original or equivalent 20x4.0 tire with an inner tube.

Why it is suitable

  • Size: 20x4.0; the manufacturer's additional inner tube designation is 3.50-16.
  • Use: wide fat-bike tires for asphalt, gravel, sand, and other mixed surfaces.
  • Material: flexible butyl rubber for good air retention and damping.
  • Model: prepared as a precise search offer for Fafrees FF20 Polar.

Checking before ordering

Check the marking 20×4.0 and the type of valve/rim on the sidewall of your existing tire. Models may vary by year or market. The inner tube is not intended for dimensions 20×3.0, 20×2.125, 24×4.0 or 26×4.0 and is not a substitute for a dedicated tubeless version. The package contains one inner tube.
