ULIP 20×4.0 inner tube for Himiway Big Dog

ULIP Inner Tube 20×4.0 for Himiway Big Dog

Model-specific offer for the Himiway Big Dog, a compact cargo fat e-bike. The official comparison states 20 × 4.0 tires. The ULIP inner tube is therefore intended for replacement on a bike that still uses the original or equivalent 20×4.0 tire with an inner tube.

Why it is suitable

• Size: 20×4.0; 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 search-specific offer for Himiway Big Dog.

Verification before ordering

Check the 20×4.0 marking and the type of valve/rim on the sidewall of the 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.
