Chamber 4.10-6 valve curved

This is a tube for an electric quad bike for children. Usually an electric 800W or 1000W with 6" wheels has 2 different tires: 4.1x6" front and 13x5.00x6" rear. The same 4.10-6 tube is used for these tires. The 4.10-6 tube has a curved valve. The curved valve will allow for easy installation of the wheel and is convenient for inflating air. The tube is made of high quality rubber, so it will hold air pressure for a long time when inflated. These tubes are also used for wheelbarrows and lawnmower tires.
