I disagree. It’s on the individual to decide what speed they can themselves handle. it’s not a car where you’re going to hurt someone else by plowing into them or into a group of people, on an ebike for the most part you’re only going to hurt yourself. (Yes yes you could hurt someone else by running into them but compared to a car it’s a much different thing). So I disagree, since you are taking on most of the risk yourself then you should be allowed to choose what you are comfortable with. Streets already have speed limits, as long as you’re respecting that then I think it’s enough. Is it safe? I don’t care, that’s on the individual to decide.

If parents are uncomfortable with that then it’s on them to regulate their own children, not force their wishes on everyone else. It’s a freedom issue, and I’m not willing to give up my freedom to choose a bike I want because other people are worried about their kids. The solution is incredibly simple: don’t buy your kids something that they can get hurt on.
