• SECURE FIT: 20x4.0 heavy duty e-bike tube suitable for most fat tire bikes with 20'' tires between 3.5'' to 4.0'' wide, including e-bikes and mountain bikes (MTB), featuring a 32mm Schrader Valve.
• THICKER AND MORE RESISTANT: Our 20 x 4.0 fat tire tubes are crafted from robust, thick heavy-duty butyl rubber material. The thicker inner tube can withstand more friction and wear, thus extending the tube's service life.
