Ultraverse 20x4.0, 26x4.0, 20x3.0, 26x3.0 Inner Tube Set with Schrader Valve-Ideal for Mountain Bikes & E-Bikes with 20/26-Inch Fat Tires-Durable & Reliable Performance 2 Pack with Tire Levers

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!

With the original tires and tubes that come with these E bikes they’re very soft the side walls you can grab with your hand and push in and we almost every time wreck when we put our brakes and try and make a turn, and we already gotten three flats with these original back tires colors a lot of thorns over here in New Mexico, But with your tires and tubes are stiffer stronger Love the way they ride un stop return you feel safe, and when we ride over thorn over here ino problems with flats. I’m fixing to order two more tubes and tires for my other E bike.

They fit well, came packaged appropriately, and most importantly, are still holding air! The tire levers are not addition, but I nearly broke them because the old tires had a steel spring to hold on the rim. I ended up cutting the steel spring on the tire with a Dremel. Otherwise, all good.

Great inner tubes. Came as promised the next day. The only problem is the little plastic tire tools they send you. Those things didn't work at all had to use the handle of a spoon instead

Both valve stems leak from the top (where you fill) . Cores are snug. If they held air I would be able to give a better rating. Update 06/10/25 seller issued credit and sent replacements. Above and beyond customer service. I changed from 1 to 4 stars.

Great quality... I received an email from Ultraverse, saying "Now that your product is delivered ...." 10 hours before it was delivered... I wrote back and said it hasn't been delivered and wrote Amazon saying it hadn't been delivered... I don't know why they sent that email so early.... But anyway... This is the second time I've bought them and they are good.... But since I thought they weren't coming today because of the email, I bought a set from two different companies to be delivered tomorrow and Saturday... One good thing now I can compare the 3 and see which ones I like the best... And I'll now have 5 spares...

I love these tires. I replaced set of original Lectric 20x3 tires on my XP3 with these. Swapping them out was a breeze. These tires are very smooth while riding and it seems to me there is less noise. the tread is quite a bit different than the stock Lectric tires, more for street riding. I do a lot of street riding with a small amount of gravel. The tread on these tires can handle both easily. I now have about 25 or so miles on these and am very pleased. My only gripe (and it is a small one) is that the nice yellow lettering is not on both sides of the tire. I think it really makes it pop. Shame it's not on both sides.

Why did you pick this product vs others?:This one looks and feels tougher than most, so far so good. Great price. If my opinion changes I’ll definitely update this post
