Duše ULIP 20 × 4,0 pro ENGWE L20 Boost

ULIP 20×4.0 Inner Tube for ENGWE L20 Boost

A model-specific offer for the ENGWE L20 Boost, a low-step fat e-bike with a Boost function. The official specification lists 20 × 4.0 fat 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 terrains.
• Material: flexible butyl rubber for good air retention and cushioning.
• Model: prepared as a precisely targeted offer for the ENGWE L20 Boost.

Check before ordering

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