Since North America is poorly designed, it isn't a good thing. If North America was better designed then biking and walking would be safer. #NotJustBikes
Even better is that you wouldn't need an e-bike either, as frankly the high speed ones are incredibly dangerous especially when there's good infrastructure for bicycling.
Sure, they're incredibly dangerous. But they're still way less dangerous than cars. I'd rather be complaining about ebikes injuring people than the countless deaths caused by motor vehicles.
Ebikes will need some regulation to limit speeds, of course.
