They worked great, good quality, and cheaper than purchasing just one I could find at a department store.

I also bought an inner tube along with the tire for my e-bike, and I’m really satisfied with its performance so far. The tube feels thick and durable right out of the box, which immediately gave me confidence in its quality. Installing it was simple and smooth—no unnecessary hassle or issues with alignment. It fit perfectly inside the tire, creating a snug and secure seal. What really impressed me was how well it holds air. After inflation, the pressure stayed consistent for days without needing any top-up, which shows it’s built with good-quality rubber that doesn’t leak easily. The valve is also sturdy and well-made, making inflation quick and trouble-free. Since replacing my old tube with this one, I haven’t experienced any flats or pressure drops. The ride feels stable and secure, and it works great in combination with the new tire. Together, they’ve made my e-bike much more comfortable and enjoyable to ride. Overall, this is one of the best inner tubes I’ve used. It’s reliable, strong, and clearly made to last. If you’re looking for a solid replacement or upgrade, I’d definitely recommend this inner tube. It delivers great value for the price!

These inner tubes are working great in my electric bike!

I think that there is something going on besides the inner tube but the fact that it's popped so many times with it being supposedly flat resistant leakage and all that I think that it's definitely not the best item I wish I could get my money back Edit: they reached out and rectified the situation and sent me replacements

They fit great, hold up good. Definitely better than what the factory put in the wheel. The only issue I had with a flat was due to my own neglect, in running to low on tire pressure and pinching the tube.

Excellent and easy install

Perfect fit. Cheap and better than going to a bike store and paying 25$ for one.
