My hilly area with year-round cycling weather is crawling with ebikes, and school-related transportation could well be the #1 reason.
All for that. But some parents made very poor choices regarding the ebikes they bought their kids, and many if not most were ineffective at turning them into safe, courteous riders on public streets and bikeways.
Now that school districts and city governments have stepped in to fill the training void, I believe the school kids have become less dangerous to themselves and others.
