I think the pros outweigh the cons? Anything that steers us away from car culture is desperately needed at this point, and this is one of the only practical alternatives in suburbia.
I would be for bike safety being taught at schools, though I feel licensing for minors would be a quagmire? Let's not go there. I would be for speed limiters that are harder to bypass. For example, I can disable mine by phone app. If I had any trouble I could ask, well, a teenager? lol
But perhaps most importantly, cycling infrastructure, at least in North America, is a joke and there is so much that can be done on the safety front it's not funny. I wish the decision makers were all bike commuters. Then they would understand the level of impracticality in their well-meaning but futile attempts to improve the situation.
This basically sounds like the regulation in Germany.
Bike safety is being taught at schools, and there is a discrete distinction between e-bikes and Pedelecs. Pedelecs, which only support while pedalling, are legally bicycles with a speed limit of 25 km/h (15 mp/h). Everything above this limit or with the capability to drive without pedalling are called E-Bikes and need insurance and some sort of license.
There is a lot NA could learn from Germany and, well, Europe in general. I'm in Canada and read an article recently about how some Scandinavian communities keep their bike trails serviceable all winter long. I wish! They pack down the snow kind of like a cross-country ski trail here but over a broader width.
