In my teens, I would occasionally take my mom's tiny single speed Schwinn cruiser out to see how fast I could ride it around Lake of the Isles. This was in the mid-1970s, and there wasn't any way to time it. A guy yelled out of his car window "Hey, you know you're going 23 mph?"
I will give you that they are not a lot of fun climbing hills.
That is pretty fast! I am barely exceeding the speeds you cited on my road bike.
