I recently upgraded my e-bike with the ULTRAVERSE 20x4 Fat Tires, and I couldn’t be more pleased. These tires are built like tanks—perfect for both urban rides and off-road trails. Build Quality & Design: The construction is seriously durable. The high-density rubber compound and thick sidewalls give me confidence on rough terrain. These tires feel solid and well-made right out of the box—no signs of flimsy materials or weak points. Performance: I’ve tested them on pavement, gravel, loose dirt, and even some snow. The directional tread provides excellent grip and control without feeling sluggish on the street. They roll smoothly on asphalt and still handle rough patches like champs. The wide 20x4" size gives that cushioned, stable ride I love, especially at higher e-bike speeds. Installation: Swapping out the old tires was straightforward. They seated well on my rims without any issues, and I had both installed and ready to ride in under an hour. Street & Trail Versatility: These really shine in versatility. Whether I’m commuting through the city or exploring forest paths, they handle it all without compromise. They also seem more puncture-resistant than my previous set, which is a big plus for longer rides. Value for Money: Getting 2 tires at this quality level is a great deal. It’s clear ULTRAVERSE put some serious thought into performance and durability. Final Thoughts: If you’re looking for a rugged, all-terrain fat tire set that performs well on both trails and city streets, the ULTRAVERSE 20x4 tires are a fantastic choice. Highly recommended for e-bike and MTB riders who want grip, comfort, and reliability.

After 700 miles I can say I love these tires! I wanted something more durable with a quiet ride and these are the ticket. My bike handles much better with these I've used them extensively on and off road. Great traction and they corner like a champ. Much thicker than the Chao Yangs that came on my bike. Appreciate the large tire levers they provided but honestly they were easy to install. They're a little spendier than some options but worth every penny. I definitely recommend these if you have anxiety about getting flat tires and the quite ride on smooth surfaces and handling can't be beat.

Recently I ordered an e bike on Amazon. But the one I ordered came with knobbies and since I commute mostly on pavement, I wanted a smoother ride. So I did some research and found people having very good experiences with Ultraverse tires ( one gentleman claimed to have 14,000 miles on a set!!). The tread looked like a good road design that could also be used in grass and gravel if I need to go around cars and other pedestrians. So I bought a set. My new ebike arrived and I pulled it out of the box and immediately replaced the stock knobbies with the Ultraverse tires. I also added FlatOut to the tubes to help seal any punctures. Though one of the selling points of the Ultraverse tires is that the tread is thick and the sidewalls are stiff. I don't expect many flats with these tires. I have to say, I absolutely LOVE the ride and handling of the bike with these tires! They're stable, smooth rolling, and quiet. They seem to be a really good combination of hardness for longevity and rubberiness for grip. And I like the looks, they look like motorcycle tires. if I ever need to replace them, I will definitely look for another set of Ultraverse tires. Edited to add: After hitting 350 miles today, these tires are amazing! It's almost comical how well they transition from pavement to grass to gravel to loose leaves... the bike just feels completely stable under all conditions, even rain. Can't say enough good things about them. In fact I just bought a set of 20x4's for my other e-bike. Keep up the great work Ultraverse!

Better than original tires that came on our Radpower Radrover 6+ bikes. A little heavier, beefy, solid. Easy to install, comes with tire levers, did not even need them to mount the tires. Quiet ride, grippy, we mostly ride on paved bike trails, but do dirt and gravel trails too. Researched reviews on top rated tires for fat tire e-bikes, these always came up. Will buy for my bike next.

'Tires arrived quickly; easy to install. Such a smooth ride, even over the cracks in the tarmac. I don't worry about getting a flat, as the rubber feels very strong. And they look great! Now I have matching tubes and tires, and I couldn't be happier. Consider me a satisfied repeat customer.'

Great tires. Big upgrade from the stock ones on my Engwe E26. I had gotten 3 flats in a month and had had it. I love the tread pattern and they were honestly easy to mount. Had to stretch them a bit but they do come unfolded. Great look. Only complaint is they seem noisy. Everyone says they are quiet...idk about that. Either way, good grip, better than stock tires on bumpy roads. Would definitely recommend. Look for deal with tubes. Save a few bucks

I recently purchased this tire for my e-bike, and I have to say, I’m extremely impressed with the overall quality. The material used feels very durable and premium, and the rubber has a really solid texture to it. One of the first things I noticed was the excellent grip—it gives a strong sense of control and stability while riding, even on slightly uneven or wet surfaces. The design is also appealing. The logo on the side adds a stylish touch, which makes the tire look even better once it’s mounted. After switching to this tire, I noticed a huge improvement in the comfort of my rides. The bumps and small vibrations I used to feel are now significantly reduced, and I feel a lot more confident while cruising around. It handles corners smoothly, and the traction is just perfect for city streets as well as light trails. Honestly, out of all the tires I’ve used before, this one stands out as the best. The build quality is simply superb, and I feel like it will last a long time. If you’re looking to upgrade your e-bike tires, I would definitely recommend giving this one a try. Totally worth the price!
