They would have to be a better trend than those AWFUL chopper looking things I see in the local Performance bike shop. I have only seen one actually being ridden. It was on a MUP and the early teen aged guy's little sister, not much more than a toddler, was complaining that he was going too slow. He looked like he was in pain and they were probably less than a mile from their car.
Lighter versions of the bikes from the 40's and 50's would be a BIG improvement of those "chopper" pieces of junk.
