Impressive stuff.
I've a fat tyre eBike that managed to develop a puncture on it's first outing. A small thorn needle, barely visible and only protruding a couple of mm into the inside of the tyre. If I'd have had this it wouldn't have been a problem. It's quite a tough but flexible liner that easily fits inside the tyre and stays in place, even when you're struggling to get the innertube and tyre back on the rim. I tried to pierce an unused part of it and it was really hard. This may mean you don't need to use Slime inside the innertube (which has a limited lifespan once applied anyhow). Certainly means you'll have more confidence you won't get a puncture in the first place. Considering how much of a pain it is to remove an electric bike tyre (especially the ones where the display means you can't put them upside down to work on the bike), it's worth every penny.

Performs well, eco friendly, great puncture protection.
These inner tubes are a more recent alternative that have the characteristics of both plastic and rubber. They are mouldable like plastic, and flexible like rubber. The reasons I would choose to use these particular inner tubes are many, but chief among them is the reduction in weight and rolling resistance, while at the same time they increase the protection from punctures. They are also a really eco friendly option as they can be easily recycled for other uses at the end of their life. If you are a rider who like myself is looking for great performance and a puncture, and hassle free ride over uneven ground, I would recommend them. They are no more fiddly to install than any other, and have lasted me well over notoriously bad ground when I tested them. I hope you find my review helpful.

Good
This tire liner is designed to fit 20"/24" bikes, providing flat protection. With its durable structure and compatibility with thick bicycle tires, it provides a problem-free cycling experience on various terrains. It allowed me to focus on the joy of cycling rather than tire maintenance. :)

This thing is tough. I cut a swatch out and tried to press a nail through. I had a very hard time even twisting it. the installation is a bit tricky. deflate the tire but not all the way. it should have a quarter inch between the tire and tube. Warm the lining up slightly. this will help with sliding it in. You can even use some baby powder inside the wheel if you are having a hard time sliding it in. It will want to twist on you. just keep feeding it slightly about 1/4 of the way around the tire. go back and tuck the first section inside. keep preparing until you have it all the way slid into the tire.

La verdad que estos protectores vienen bien para los abrojos, aportan resistencia a las cubiertas y la instalación es sencilla, no he notado ninguna diferencia a la hora de rodar pero si es cierto que, en este tiempo no he pinchado. La mejor forma de agradecer el esfuerzo por ayudarte a decidir es dándole a útil en esta reseña, gracias!!

Very happy with my purchase. Install can be a bit tricky but I found if you let air out it helps and if it is still tricky let more air out easy peasy. You must trim to proper wheel size if not the wheel will be unbalanced. With the piece that I trimmed off I tried to drive my Cutters through the center I found that I could not very impressed I think this will work much lighter than slime. Should improve my mileage and top speed
