Great tire.
I bought these tires to replace the tires on my new ebike. The factory tires were this. These are quiet and they handle all conditions well.

I just had this tire installed on my daughter‘s e-bike, and it is beefy and a great looking tire. She has only put a couple miles on it and said it feels really smooth and grips the road well. I don’t have much to report yet, but for the price, it seems to be a super great tire and the installer at the shop said it’s one of the beefiest he has installed in a long time.
