Fantastic tires, smooth ride, and very quiet. So much better than the stock tires that came with my e-bike. Hugh upgrade, can feel the difference right away. I ride mostly, pavement, these are for the road. And they are nailing it!!! Little finicky getting them on. Trick, watch the marks, and a spray bottle with a little soapy water. I also, installed heavy duty tubes, and flatout! So hopefully no more flat tires!

Purchased a pair of 20x4 tires. Compact treads to prevent flats and ensure a ground gripping smooth ride. Easy to install. After the first ride I knew I picked the right tires. I did not hear the tires at all. All I heard was the motors on my E bike. ๐๐

First time changing tires on my ebike, my lord it was a process. Close to 2 hrs. Made sure to take my time. These tires are absolutely amazing compared to the stock tires. Smooth, soft ride, incredibly quiet. Could not be more pleased with these. I will always use this brand and tire. Thank you for a great tire!

These are good tires and feel that you get the value you pay for it is they are just too hard to balance and get wobble out of. I kept the front one on but had to replace the back tires as it was causing issues. They are also hard to install, relatively.

Thick tires The best way to mount these tires are to layer them sit in the sun most the day. Then they are easy to install. If you donโt good luck. I tried to mount them cold. They gave me a fight. So I quit but set them in the sun all day. Then in the afternoon while them were still warm I tried again and the went on like a different tire. Very easy install. I have rode on them yet but wanted to give you all that tip. Nice thick strong tire. Look amazing. Spin true after I put 5lbs psi. And worked them around. Then I aired them up to 30 psi after leaving them in the sun the next day for most the day. The low air pressure swelled them up enough to soften and self seat. Then aired them up to max pressure And spun them on the bike with the bike upside down and they spin smoothly no out of round. Because of letting them side up with low air pressure. Out of the box they are not round and fat. I was worried. But they came a round with the warm sun, low air pressure,and time.

Appears to be a great bike tire. Much thicker than most on the market. Good fitting and quiet tire.

High quality tires. But weight a lot! Lost about 3 to 5 mph on these. Felt great riding but makes your battery work harder and drain faster. I do not recommend unless you have a ebike that goes up to 40+ mph. Put back my Chinese tires and my bike felt lighter and faster. I ended up just upgrading the inner tubes with a shield puncture liner.

Couldn't ask for a more solid design. My ebike runs 50mph and I needed tires I could trust and went through the cheaper brands before I found these. I'll be a lifelong customer now!!! Side walls are solid, tread is silent and sticks to the road like they should, water isn't an issue, and I'm getting more top speed and battery life with these. Well worth the money, don't waste time trying other brands like HEB and Allscape and that's coming from an avid everyday rider!!! You get what you pay for and these tires are worth every penny!!! If you're looking for safety, silence, grip, durability, less resistance, more battery life, and more top speed on your Ebike you found it in these tires!!!
