Thicker 40% 14 x 2.125 Inner Tubes Heavy-Duty 14 Inch Electric BikeTubes for Replacement Electric Scooters and E-Bike Tire Tube 2 Packs

14x2.125 TUBE: This inner tube model is 14x2.125 with CR202 Angled Valve Stem, which is used to replace 14x2.125 / 57-254 Electric Scooter Tire tube.
Heavy-Duty 14 Inch TUBE: The upgraded STAIBC 14x2.125 inner tube is 40% thicker than the regular ones, which not only makes the tires have better load resistance, longer service life. But also excellent in withstanding the wearing effects of weather, such as not cracking in high heat & maintaining flex in colder temperatures.
SAFETY: This inner tube is made of thick butyl rubber, which is better in air tightness, elastic damping and aging resistance than natural rubber. With thick butyl rubber that absorbs shocks, you won't feel the bumps and hollows because your bike will glide along, protecting you from the force.
PACKAGE INCLUDES: 2 packs 14×2.125 Heavy-Duty inner tubes.
365 DAYS WARRANTY: STAIBC service will provide 365 days of quality after-sales service with evidence provided, which is not caused by human destruction or improper use!
