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!

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.

Best Fat Tire for E-Bikes – Unmatched Performance, Comfort & Durability The Traverse Fat Tire 26 x 4.0 is hands down the best tire I have ever used! As soon as I installed them on my Aniioki A9 Pro Max Plus, I immediately noticed the superior grip on pavement compared to my stock tires. These are true all-terrain tires—whether on pavement, dirt, or trails, they handle everything effortlessly. Unmatched Ride Quality & Stability I ride 75% on-road and 25% off-road, and these tires perform flawlessly on both. The ride is smoother, thanks to the softer compound that absorbs road imperfections better than any other tire I’ve tried. Even at 45+ mph, I feel completely stable and in control. These tires also give my bike a premium look, which is a nice bonus. Puncture Resistance & Reliability I purchased these tires because I needed something heavy-duty. After a flat left me stranded, I wasn’t willing to take that risk again. Now, with these tires and FlatOut sealant, I haven’t had a flat in years. I ride throughout San Antonio, averaging 50 miles per ride, and these tires have never let me down. Proven Performance – Even at 100+ MPH! For those who need social proof, the popular YouTuber “E-Bike Guy” uses these on all his custom builds. He even reached over 100 mph on these tires—that alone says a lot about their durability and performance. Final Verdict If you’re thinking about these tires, just buy them! Whether you ride mostly on pavement or venture off-road, these are the best e-bike fat tires on the market. Highly recommended!

The tires were of great quality and easy to mount on my ebike. Even came with a pair of metal tire levers as a bonus though I didn't have to use them. It was a nice gesture I thought. They are a little heavier than my original tires but was impressed on how nice they rode. I may lose a little range but I can live with that because of the quality. Would I buy them again? Absolutely, without hesitation.
