Product Description

PRINCIPLE

During riding, when the inner tube is punctured, the self-replenishing fluid in the inner tube is ejected from the punctured hole at the pressure of the outer air. The self-replenishing fluid condenses rapidly at the puncture hole, blocking the puncture hole, thereby preventing the tire burst phenomenon in the riding process.

【Easy To USE】The Self Sealing Bike Inner Tube is a self-repair for some small holes or very fine cracks. For example, after a long time, some places will leak air quietly, accidentally hit nails and other problems, which are easy to repair.
It is worth noting that our self-repairing inner tube can be used normally at room temperature and 0~-15℃, and it is more conducive to travel in cold weather.
🚵‍♀️【Please note】 1. Because the Self Sealing fluid is flowing, in order to prevent the liquid from flowing out during operation, please do not concentrate the center of gravity or the liquid near the air nozzle when pumping up.
🚵‍♀️【Safe Bike Tires】 Pre-installed with Sealant to provide maximum puncture protection and prevent flat tires on your bike.The self-repairing inner tube is a thicker design, which is more durable than the normal inner tower. The bicycle inner tube rolls through the tire repair liquid to automatically fill the punctured area. After testing, the leak can be repaired within 5~8 seconds under normal conditions.
