Way thicker than OEM ebike tires
I have the same comment as another review here, so I do not understand why that one gives just two stars - a mistake? Anyway... the tires my ebike came with were so thin that I kept getting flats from really small road debris. I replaced them with R4FTs and so far so good. They are also knobbier than the originals so not as smooth of a ride, and they are much stiffer so installation is a pain (use bigger longer tire irons - the little plastic bicycle tools are not enough). But not getting flats anymore is a worthwhile trade off.

Great Tires
Bought an electric bike and the tires were almost paper thin. Had 6 flat tires in 3 mths. Replaced them with your tires and the ride is smoother, better grip and so far no flat tires. Thanks
