2 Pack 26 x 4.0 Fat Tire Tube Schrader Valve, Puncture Proof Bike Tubes for 26 x 4 Bicycle Tire, Butyl Rubber Inner Tube for EBike/Electric Bike/Mountain Bike

Great for mok e-bike

I keep seeing claims of how superior presta is, but my experience is that the only upside of presta is having the little nut holding the valve in place. In my experience, presta valves typically leak more, are much harder to use since you need an adapter with most inflators, and just cause a lot of issues...These tubes fit perfectly, hold air better than my old ones, and were easy to install. Very happy with them!

Seems pretty heavy duty for my 4" fat tire e-bike. I will be sure to update if they prematurely fail but so far so good.

I did not use the plastic tools that came with these, but the tubes were easy to install in the tires of my rambo rooster ebike. They pump up easily and seem well made and durable. They are everything I was hoping for, and priced right.

I ordered the 2 Pack 26 x 4.0 Fat Tire, Schrader Valve, Puncture Proof Bike Tubes for my fat tire ebike, to decrease the likelihood of having a flat while out riding. The product description says "puncture proof" but that's a bit of a stretch, (no pun intended) because there isn't a tube out there that won't puncture, given the right conditions and sharp objects such as large pieces of glass, industrial staples, nails, and thorns. However, these tubes are thicker than average and do offer a greater level of puncture resistance than regular tubes, making them a superior product.

So far, I haven't had any flats using these new inner tubes. These are thicker than the original tube included on my bike, so I have a feeling they should last a good long time. So far I've been using these tubes for a little less than 2 weeks, and I've been very happy with them. The size is a perfect fit, and installation was straight forward, with no problems. It was nice that they include tools to help remove the tire, but I imagine most people already have these tools.

I got a brand new bike and a few days after getting it the front tire developed a slow leak. I took it out and patched it and it was fine for another week but then it started leaking even harder. I patched it again but it didn't do any good this time so I had to declare it dead.I got these replacement tubes and replaced my front one and I haven't had any issues since then. I also have a spare on hand now for the next time I get a puncture.

Exactly as described in the listing, these are heavier/thicker fat tire (26x4 in my case) inner tubes. My e-bike has recently had multiple flat tires, front and rear. I just installed one of these with ease to replace the currently leaking rear tire's tube. It seated and inflated with no problem, so far so good. With the heavier use an e-bike's large/fat tires generally experience, I'm wishing I had been using this type of tube from the beginning; they definitely appear more capable of withstanding the heavier loads/distances traveled on an e-bike.
