Schwalbe AV6 BMX Inner Tubes - 20 x 1.10-1.50, Schrader 40mm Valve (2 Pack) Schwalbe AV6 BMX Inner Tubes - 20 x 1.10-1.50, Schrader 40mm Valve (2 Pack)

it fit my bike, was easy to install, so far no problems.

Excellent tubes, zero issues, all great! I have changed tubes to Schwalbe on all four bikes. Why, because the cheaper tubes fail. Cheaper tubes seem to have common failure mode, leaking around valve stem where molded to tube. Cant realistically patch that!

I love the fully threaded metal valve stem and nut. I hate it when the tire and tube slide on the rim and make the valve stem misaligned, and then as I try to get it straightened out I always seem to overcorrect and make it go crooked the other way. This design eliminates that hastle. Also, when first going to put air into it (and if you ever get a leak/flat and need to air it up again) the valve stem doesn't push into the rim and make it difficult to attach the air pump. Other than that, there's not much to say. It's an innertube. It holds air. I've only ridden about 20 miles on it so far, so I can't comment on durability. The valve stem though is awesome, and if you've never used a tube with this design, I cannot recommend it highly enough. Happy pedaling!

Available and quick. 20" x 1.2" tire size for a folding bike.

Quality

Go the whole way and get quality tunes. The clear cap signifies their brand.

These seem like nicely constructed tubes. Like getting two so I have a spare. They fit my 20x1.25 perfectly and will easily run the 50psi I need to run (rated to 72psi, I also like the keeper nut on the valve stem, nice touch.Time will tell but so far very impressed.

I like these tubes because I trust the metal valve won't fail. But twice now, I've had brand new tubes split at a seam. Of course, since these are backups for a future failure, they don't come to light until after the 30 day return policy. I guess the price I have to pay since, even with the failure rate, they are better than others I've used, esp. since it's hard to find 20" x 1.5".

After desperately searching the internet for bike tubes thin enough to fit my Giant Expressway 1, which by default comes with super skinny city tires. (Finding skinny tubes for 20" rims is not fun). Finally I broke down and bought these because they were the only ones I could find without looking overseas. They arrived, and they fit! And the quality is actually as good as advertized. I only needed to replace the one tube, and I can see the difference in how long it takes them to lose air. The Schwalbe tube takes approximately 50% more time before I need to pull out the pump again. I wasn't enthusiastic about the price tag at first (isn't all rubber the same?), but now I can confidently say they're worth the money.

Decent quality

The Schrader 40mm valve is too short for most bikes, making it difficult to pump air. To maintain sufficient air pressure for cycling requirements, frequent inflation is necessary.
