People under 16 probably shouldn't be driving vehicles very fast period. That doesn't feel like a double standard since we've already banned them from driving cars.
A 15 year old on a bicycle can easily do 15mph, and even 20mph is easy enough if they are willing to pedal for it. The real problem is that something capable of doing 15mph+ shouldn't be on the sidewalk in the first place.
There are multiple things going on in these situations, and rarely is it just one thing a quick simple ban on ___ will actually fix
