Well made, high quality, good ride
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!

Best one I've purchased!
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!

Best tire upgrade You can do
Excellent customer service and high quality product(s). The Ultraverse tires are superior strength and design over the stock cheap tires supplied with e-bikes. The design and materials are instantly noticed when touching and comparing them to stock tires which are thin and flexible with soft sidewall design. The rubber compound of the Ultraverse is far thicker in quality with non foldable tire sidewall and design. Installation is made very easy with the instructions and available videos, and the supplied metal installation spoons with new tire(s) purchase. Additionally, the tire tubes are thicker gauge rubber as compared with stock tubes and look and feel of a superior product. The tubes came with supplied plastic style tire bead tools which additionally has a tire valve removal feature if you need to remove the Schrader valve. Fit and design is excellent. You will immediately notice the difference on your first ride after installation as tires are very smooth on the road, less vibration than stock cheaper tires supplied with ebike which are ( Kenda ) branded tires. The tire balances with ease if you follow installation advice and available instruction. These Ultraverse 20 x 4 are the best upgrade you can make and rolling resistance of tire provides a very high quality feel on the road while allowing bike to peddle easier and produce increased distance between charges. You will not be disappointed with this product or the responsiveness of their Customer Service ( Ana ) if you have any questions.

Rides nice. Good quality
Shipped in full size box. Side walls are nice and hard but the logo are only on 1 side. The treads are thick and does pretty good going up loose dirt road. They weigh 4 lbs 4oz each. Rides quieter than stock 20x4 knobbies. Recommend inflation up to 30 psi but they are smooth at 25 psi. Comes with tire pry tools. Install was straight forward.
