ZOL Multipack Fat Tire Bike Bicycle Inner Tube 26" x 4.0 Schrader Valve 48mm

I bought a fat tire bike a while back. Picked up a flat running over a nasty thorn. Looked like the tooth from a wild animal. Tire went flat, ride was over and I couldn't find this tube size at my local stores. Found this one here and ordered it. Fit perfectly and went on just like any other bike tube. Seems to be holding air and doing it's job. Hopefully I wont need another one for a while but if I do, I'll be getting one of these!

I purchased these on July 19th, 2018. They were installed by a professional at a Denver located bicycle shop. I was then unable to ride for 6 weeks due to surgery and recovery. When I was able, I rode 3 to 4 times per week. So, in total, about 20 rides, each about 5 miles. The rear tire is already flat as a pancake. These tubes are not the quality that I expected.

After my 2nd or third flat, I decided I would replace the tubes myself and cut the old tubes into tire liners. Not only are these about the same price as the ones installed at my local bike shop (minus labor which makes it about even) I would say they're 30%-50% thicker than the cheap crap my bike shop installed. Definitely worth getting the 4-pack. I recommend getting the right tools as well. I had a heck of time changing the rear tire. Front tire nearly fell off on its own...Go figure.

The tubs are thick and the stems are long with Schrader valve's. I'm very happy with the product. I easily filled the tubes with Green slime and now no more worries about flats. When I wanted to check my tire pressure, it was easy with no special equipment as with tubes that has the Presta valves.Delivery was as promised and very good packaging. FIVE STARS!

I received these tubes quickly and upon initial inspection they appear to be in excellent condition. I'm sure I will use at least one of them in the upcoming months, I will update this review upon use.

It was easy to install, with also adding some slime in the tube and the liners for extra thorn resistance. Which makes this a great tube for long distance riding. I also have a couple of these in my duffle bag, just incase for flats.

This is a high quality replacement/spare tube for my 1,000 watt fat tire 26”x 4” e-bike. The rubber on this tube is heavy duty and thick. I always add tire sealant to my tubes to prevent flats but this tube is reassuring. It was delivered quickly and in perfect condition.

I have not used yet but they are definitely thicker and made of a better rubber then the ones that came with my new fat tire bike... I know because I have had two flats.. ordered these for the next flat..
