Concord Replacement Bicycle Inner Tubes, 20", 4 Pack, Schrader Valve

Some inner tubes you just can't patch, so why not get a value pack.... Always good to have some on hand...

well. It fit. And the bike now goes. it has not spontaneously popped in the days since I installed it. So for the money, i'd say it is performing exactly as expected.

Can't cry about a 3dollar bicycle tire tube.

This is a inner tube for a 20" bicycle tire. It fits tire widths 1.75" to 2.25" and this was actually one single tube. It's a perfect replacement for my son's 20" bicycle. It's a nice quality, thick inner tube and will likely hold up for a few years.

Relatively easy and quick installation, but you must know or at least have an general idea on how to replace the inner tires on bikes. With helps of online videos, I was able to replace both tires within half an hour. Given that I had no previous experiences. They have been great ever since, revived my bike that's been neglected for years in the garage. Highly recommend

recently replaced my worn-out bicycle tire tube with the model, and I must say, I'm thoroughly impressed. This tube has exceeded my expectations in terms of performance and durability. First and foremost, installation was a breeze. The tube fit snugly into the tire without any hassle, and the valve stem was easy to secure. This saved me valuable time and effort, allowing me to get back on the road swiftly. In terms of performance, the tube has demonstrated exceptional puncture resistance. I've ridden over various terrains, from rough gravel paths to city streets filled with debris, and it has held up admirably. I was pleasantly surprised at how well it withstood sharp objects, providing a worry-free riding experience. Furthermore, the tube maintains consistent pressure over extended periods, reducing the need for frequent re-inflation. This not only enhances efficiency but also contributes to a smoother and more comfortable ride. Durability is another standout feature of this tube. It has shown resilience against wear and tear, even after numerous rides in challenging conditions. The high-quality materials used in its construction are evidently designed to withstand the rigors of regular cycling.

I only received 2 of the tubes because 2 tubes was missing from the box

When I got the package, there were supposed to be 4 tubes in it. There was only three, so either someone stole one out of it at the store or the person delivering.It stole one and only gave me three

was missing two inertubes

This product was not as described at ALL. It said that it was a four pack, we got ONE tire liner. Then, the ONE tire liner that we got, didn't even hold air. We replaced our child's liner with this one, aired it up, everything seemed great, then it went flat the same night. We looked all throughout the tube checking for the leak, and couldn't find it. We believe it was a manufacturing defect. Either way, we do NOT recommend.
