CALPALMY 20x4.0, 24x3.0, 26x4.0 Fat Tire Bike Inner Tubes with 32mm Schrader Valve, Fit for Electric Bikes, Mountain, Off-Road & Beach Cruiser, Made from Durable Heavy-Duty Butyl Rubber (2 Pack)

These are great. They do the job and came quickly. Replacedy son's tires after he got a flat and got him riding to school quickly. We've had them on his bike awhile now and they are still doing well.

Works great. Good quality tubes.

They are thick and good quality. I used it to replace my blown rear wheel. It was thicker than the one I replaced. I added slime and put 20 miles on it so far...

My slimed tube encountered a nail and left me stranded. I thought I was invincible. Guess not. I bought this 2 pack of tubes and didn't bother sliming for a 2nd time. Why would I. So far, I haven't needed it. This tube is holding! And now I have a spare in case it does eventually go. After I submit this, I'm going to leave a negative review on slime. LOL

These work as well as any other tire tubes. They work well for a fat tire e bike that goes off road. They hold air with no leakage. They are reasonably thick. They come with a little toolkit to help with installation. These are a good value.

Brakes for my E Bike. Easy to install and they work perfect. Great deal on top of that. How long they last is unknown but I only got 300 mile on the original ones and they want $40.00 plus tax plus shipping which would have made it about 50 bucks for one set. I have 2 e bikes so this was perfect even if they don’t last 300 miles. Can’t go wrong. Got them in one day also. Another plus vs waiting a week.

Nice and affordable

Fits my ebike after it had a blown out tube. Relatively inexpensive compared to others on Amazon. Does the job, came with small tire removal rods as a bonus. 5/5
