SunliteBicycle Tube 12-1/2 x 2-1/4 (1.75) Angled 70 Degree SCHRADER valve

Installed on e-zip 500 rear wheel. The installation process is a learning experience for the rear wheel because the tires are very hard to remoe from the rim, and you have to disconnect the brake line and motor mount to complete the installation, but the inner tube worked great. Plan on two hours for this job if you have the tools and are handy. As with any new tube, I recommend checking for leaks in the sink BEFORE installing. It would be no fun to have to do this job repeatedly.

The pictures do not show the valve very well. The valve is obviously bent, but the direction is not straight out. In other words, it does not form a 90 degree angle with the tube if you look at it from above, so it does not stick out as much as you may expect.The box says Sunlite (as pictured), but the actual tube was marked Kenda. I used it for a Bugaboo Frog stroller where the original tube and tire were both Kenda as well, so that seems like a good sign. I was concerned it might be some custom size, but both the new and the original tubes have clearly marked sizes. If you are not sure if this is the right tube for you, check the tire or take out the old tube first and see what it says. In my case, they were identical, except the valve on the new one is angled, which is much easier to access.One issue that I did not foresee is with the actual wheel I was putting it on. The wheel is made of thick plastic and the opening for the valve is not just hole, but is a small tube. If the valve is straight, it would be simple to put it through. However, since the valve is bent, that part was difficult.When installing make sure the tube is not pinched under the tire rim. After you pump some air into, wiggle it a bit to make sure it is completely inside the tire.

Bought this for the rear wheels on my Phil & Ted double running stroller. Perfect fit and I like the angled valve, it makes filling the tires much easier. The valves on my previous inner tubes were straight so I had to buy an air pump specifically for the small tires. Now I can use any of my pumps, which is much more convienet.

This tube has a 70-degree angled brass valve, which makes filling the tire much easier. I used this tube on a jogging stroller 12" wheel, and it was much easier to get the pump head on this valve, with no need to try to fit the pump head into the very small space within the wheel spokes.The valve does not stick out very much, maybe about an inch, but that makes all the difference.This is also very thick rubber tube, much heavier than the old tube I replaced.If you're replacing a similar tube, and the valve access is tight, consider spending the extra $1 or so to get this tube.One other tip if you're not experienced at replacing an inner tube - after you get the tube in and reseat the tire on the rim pump up the tube one or two strokes just to give it a little shape. Then hold the valve and push it into the tire a few times to be sure the tube isn't pinched under the tire rim. Finally grab the tire and rock it back and forth as you go around the rim, which will help seat the tube. Pump it up slowly. If any portion of the tire bead starts to lift, let the air out and start again, as the tube is still pinched under the tire bead at the spot where it lifted.One more tip - talcum powder (baby powder) - sprinkle some on the tube before installing. It helps the tube slide inside the tire, making it easier to seat the tube.

Used this tube in a Quinny Buzz stroller. It's works great as long as you make sure you put the valve the right direction. I didn't think about it, I just threw it in there which ever way and of course got it wrong the first time. Of course! So the valve has to point out (probably obvious to some, I've never personally replaced any kind of tire tube before, so I didn't give it any thought), not towards the inside of the stroller. If it points in it hits the inner wheel workings. Will still roll but is SUPER annoying and will scratch stuff up. SO! Make sure your valve points out, works perfectly! Soooo much easier to fill that the stock Quinny tires that don't have the bend in the valve. Hindsight, I should've just ordered two of these, because now the second stock Quinny tire is leaking.

Wow, was I pleased with this tube! Why? It has two GREAT features that overcome a major problem with filling the tire with air: the valve stem is brass and it is angled outwards.Problem: because the small wheel has spokes that are very close to the air stem, a normal rubber, vertical stem has to be pulled sharply to the side in order to get the air hose over the nozzle. Every time this is done, the rubber stem is both stretched on one side and also driven against the relatively sharp edge of the hole in the rim. Basically you're trying to damage the stem in two different ways when you air it up.The brass, pre-bent stem alleviates both of these problems. 1, It is angled outwards so the air nozzle will connect without applying any force laterally to the stem; 2, Since the stem is brass, it is not subject to any cutting or shear effect from the rim hole.Awesome!

I purchased this tire tube and when it came in there were two small holes in it like it had been punctured by a staple. I am not saying this is a common thing just what happened to me. The tube itself was manufactured by Kenda, which is a name I associate with quality bike tires, even though the box says sunlite. Also, having the angled valve would make it incredibly easy to inflate once installed. However in my situation I quickly learned I would pay as much in shipping the defective product back as I had paid for the bike tube to begin with ($6.88), so I sucked it up and went to Wal-Mart. At Wal-mart I found a Bell 12-1/2 tube for $3.88 it has a straight valve but it does the job. Knowing what I do now I would not buy this product off Amazon again due to shipping cost in cases where the product is defective.

Perfectly matched with my scooter tire, just thinking to by one spare.

This was want we needed to get the bike back on the road. The valve was a little short ( that’s what she said ) but it got the job done

tube leaked out of the box have patched it and am using it.

Well it looked good at first but the valve let loose after 2 days, it literally separated from the tire.... so there you go.
