Heavy-Duty 14x2.125 Inner Tube with Angled Schrader Valve Stem for Electric Bike Tire Tube, 2 Packs

Good quality, easy-to-use. Worked as expected.

The idea of an offset/angled stem is a great idea. I used these on my daughters electric scooter. With the motor being mounted in the rear hub on the rear rim, there is very little space to try and air up a tube with a regular stem on it. The offset stem makes it much easier to air up the tube. I will not be going back to a regular stemmed tire. The metal stem is also a great upgrade. I hope they last a few years.

so far so good

I needed this because it has the angled valve stem. The straight valve stem models I couldn’t check with my gauge. These are excellent and I would recommend.

Excelent
