Currently use these on my grocery getterneighborhood cruiser. Used to use them on my regular road bike. Compared to a slick 700x25 tire, the tread slows you down but only by one mph or so. I'd love to try Maxy Fasty 650b slicks but who can afford $52 each. These are very long wearing, have great traction, are good for everything other than high performance rides and are an absolute bargain at less than $20.
