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)

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...

Nice and affordable

so far these tubes are holding up great on my Ebike I ride 100 miles a week on some bad streets in Toledo Ohio and out of all the tubes I bought this band is holding up the best

Good fit. Good price.

I'm using one of these to seal the window between my pick-up cab and cap. My dog probably won't like it as he likes to 'sniff' in this area, when I close the side windows in winter. Tight seal with plenty of extra length for my tacoma trail pick-up. I tried a couple pricey window cab/cap sealers, but they leak. Will keep rain, snow and leaves out of the bed. Give my dog a little more warmth that he doesn't need. A lot cheaper(& better) then the commercially made cab/cap window sealers.

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

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.

These tires have ridges where the air valve is and all 4 I purchased I had to replace within a few weeks as they wouldn’t hold air. I used a leak detector spray and all 4 tires leaked in the ridges.
