BulletPoint2 : Compatibility: Our tubes are compatible with most gas and electric scooters and children's bikes with 12-inch to 12.5-inch tires that are between 1.75 and 2.25 inches wide. BulletPoint3 : High-Quality Material: This inner tube is made of thick butyl rubber, providing superior wear resistance, puncture-resistance, and anti-skid performance.It is superior in air tightness, elastic damping, and aging resistance compared to natural rubber. BulletPoint4 : Durable Tube: Featuring a high-quality reinforced valve that preserves more pressure and withstands any pressure changes, this solid tube has been developed to respond to uneven road conditions, providing durability and longevity. BulletPoint5 : Please check the shape and size before purchase. It is strongly recommended to wear anti-puncture strips for extra protection. While the tubes are thicker, they are not indestructible. If a tip penetrates your tire, your inner tube can be pierced. Before installing, wrap the pointed end of the crowbar with a fiber cloth to prevent damage to the inner tire and coating of the hub. BulletPoint6 : Tip: Before installing the inner tube, please put the inner tube into the water for inspection, if there are bubbles, it means that it has been damaged, you can contact us. Check the valve position to ensure that the installation direction is correct. Note: The inflatable inner tube should avoid puncture by sharp objects.
