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 14x2.125 INCH TUBE: The upgraded 14x2.125 inch inner tube is 40% thicker than the regular ones, which not only makes the tires have better load resistance, longer service life.
SAFETY and PERFORMANCE: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.
ABOUT THE PSI: The PSI of the inner tube is determined by the PSI marked on the tire, We recommend inflating the tubes up to 36PSI to help extend their lifespan.
