Tube, 20", Select Size & Valve Type. 1 Pack or 2 Pack Money Saver. Regular or Presta Valve Bicycle Inner Tube, Sunlite, BMX, Recumbent, Stroller, Youth Bike, Toddler Bike, Trailer

I purchased the 20 x 1.25-1.50 and I don't know what some reviewers say about the tubes being larger than 20". Tubes will look larger without the tire but that doesn't mean they are larger than the advertised size. I compared the diameter of this tube with the original one that came on my folding bike and the tube size is identical (it does look too large for the wheel). Also don't let the Sunlite brand deter you as the tubes are labeled 'Kenda' on them. You can tell good quality tubes as they have some thickness to them at the base of the air valve, as is the case with these tubes. Finally I took out my Presta valve wrench and the tubes DO have removable valve cores. Pretty much checks off all the boxes for me . . .

Good product. I use the same brand of tube at work. I up keep a fleet of three wheeled bikecycles at my job . 16 adult three wheeled bikecycles to be exact . I used many brands before . So far I am very happy with this brand . Bought these tubes for my son's BMX bike . If this product holds up to a bunch of adults. It should last my son a long time.

these tubes are a great fit I use them on a folding training bike far exceeds the basic functions of my other tubes one thing to keep in mind though these are presta valve tubes if you have regular shrader valve rims like I do you'll need the insert converters right here on Amazon they are worth it get a couple of pairs just in case AND THEY HOLD HIGH PRESSURE FOR WEEKS hey best buy anywhere!!!!!!!

When I went to install both tubes on my bike, only one tube fully inflated. The one that did not inflate seemed to have a defective valve. I contacted the seller and, surprisingly. got an immediate response. I was sent a replacement tube, which inflated well and was installed on my bike. So far they both have been fine on the bike and I'm hoping for no flats!

Was a little leery buying these inner tubes after reading the reviews. But I did not have any issues with the tubes being too big or too small. They seemed to be well made and I had no issues inflating one to 85 psi.

quick shipping. used on Lectric 2.0 Ebike

Ordered 20" X 1 3/8" tube for my kids bike. It it was larger than the old tube it replaced but supposedly the same size.Had to fold over a good bit just to fit it all back together. We'll see how it works. Now the tire doesn't sit properly seem centered on the wheel due to excessive tube overlap.

I use these on my recumbent trike... so far so good... No failures
