## Description

desertcart.com : 2 Pack 20x4 Fat Tire Bike Inner Tubes with Schrader Valve, 20 x 4.0 Premium Butyl Rubber Inner Tube for 20 inch Ebike Electric Bicycle : Sports & Outdoors

Review: perfect fit for fat bike tires - The material feels thick and durable, they inflate well and maintain pressure without any problems. The Schrader valve is of good quality and doesn't leak. Installation was easy and they fit perfectly.
Review: Functions perfectly as expected - In the annals of cycling, where tales of epic climbs and daring descents are etched onto every dusty path, there exists a lesser-sung, yet no less vital, legend: the inner tube, but not just any inner tube - the 'Premium Butyl Rubber Inner Tube'. This wasn't some flimsy, mass-produced rubber circlet. Nay, this was a masterpiece, a whispered secret forged in the fiery heart of a forgotten vulcan, imbued with the spirit of the ancient roads themselves. Its very touch radiated a resilience that promised untold miles of unfailing service, even through the most treacherous terrains. Forget the flimsy, patch-prone nightmares of lesser tubes. The Premium Butyl Rubber Inner Tube was woven with whispers of puncture resistance, able to shrug off the sharpest thorns and malicious shards that sought to impede a rider's journey. Its ability to retain air was not mere engineering; it was a pact with the very element, holding true against the whispers of insidious leaks that plague lesser tubes. Installation was not a chore, but a blessing. It slipped into place with the ease of a well-worn tale, its form molding perfectly to the curvature of the wheel, ready to embrace the journey ahead. Oh, the tales told of its unwavering performance! Riders spoke of traversing desolate mountains and bustling cityscapes, their minds free from the nagging fear of sudden deflation, thanks to this legendary tube. It whispered promises of smooth, unwavering rolling, transforming every bump into a barely-there tremor and granting a grace that verged on the miraculous. Some even dared to say it smoothed out the roughest asphalt as if a fresh layer of tar had been laid down before them. The Premium Butyl Rubber Inner Tube, though silent and hidden, was the very foundation of their freedom, the unspoken promise of adventure around every bend. A relic of a bygone era, perhaps, but its spirit lives on in every flawless journey, a reminder of the true potential held within the humblest of components. I paired it with green slime because we are blessed with goat head stickers, the bane of existence. So far, they function like a dynamic duo, nay better than psychotic and schizophrenic silver spoon dressed like a bad comic-con character and his infatuated and naïve sidekick.

## Questions & Answers

**Q: Does this fit a Radpower Radrunner?**
A: When it comes to tubes I wouldnt see if it works on a brand of e bike but just make sure it fits your rim and tire size. I bought this for my brother who has  juiced scorpion and a tire size of 20x4. Hopefully that helps.

**Q: what psi are the inner tubes rated for?**
A: Not 30psi….I just put one in my tire and inflated to 28psi and 3 minutes later, KABOOM! Tube blew out, scared the $¢!T out of the cats!!!

**Q: What are tire levers used for?**
A: They are little levers that are used for getting tires off a rim. A set of tire levers are one of the cheapest and most essential tools of cycling equipment and everyone should carry them. To use them, insert flat end between rim and rubber tire. Lift rubber tire up using leverage off rim and bring rubber tire edge off and away from rim edge. Drag lever along rim edge to bring tire off rim further.  Careful not to pinch tube in this process. The opposite end of the lever is for locking it on to a spoke.

**Q: Has anyone used these for their Super73? If so, how’d it work out? :)**
A: I bought these tubes for my brothers juiced scorpion which uses 20x4 tires and they worked fine. Hopefully that helps you out.
