ULIP 20×4.0 inner tube for Fiido T1 Pro

ULIP Inner Tube 20x4.0 for Fiido T1 Pro

A model-specific offering for the Fiido T1 Pro, a cargo fat e-bike. The official EU website lists CST fat tires 20 × 4.0. The ULIP inner tube is therefore intended as a replacement for bikes that still use the original or equivalent 20x4.0 tire with an inner tube.

Why it's 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 cushioning.
• Model: offered as a precise search result for the Fiido T1 Pro.

Check before ordering

Check the sidewall of your existing tire for the marking 20x4.0 and the type of valve/rim. Models may vary by year or market. The inner tube is not intended for dimensions 20x3.0, 20x2.125, 24x4.0, or 26x4.0 and is not a substitute for a dedicated tubeless setup. The package contains one inner tube.
