Specialized Inner Tube

Yes, this tube is specifically designed for 12-inch wheels with an ISO diameter of 203. It is a direct replacement for standard 12-inch bicycle tires.

The outer wall is reinforced to provide extra protection against thorns and debris where punctures are most likely to occur. The inner wall is kept thinner to minimize rotational weight, ensuring the bike remains easy to pedal.

On smaller 12-inch wheels, space around the hub is very tight. The angled valve makes it significantly easier to attach a pump head without struggling against the spokes or the rim.

Yes, this tube features a Schrader valve, which is the same type found on most standard bicycle and automotive tires. You can use any standard floor pump or hand pump compatible with Schrader valves.

Yes, the valve core is removable. This is helpful if you need to replace a damaged core or if you want to inject tire sealant directly into the tube for added puncture protection.
