I doubt 'European' trends can be exported to America, at least with regard to E-bikes. Europe is much more regulated and living tends to be centralised or to follow public transport links.

I keep hearing about Europeans touring on E-bikes but as a European who tours in Europe I've only ever seen two people doing this. I think many of these reports are from Americans who have been touring the Danube or Rhine where a lot of locals and tourists off river cruises use them for day trips. In Ireland where I live I have noticed an increase in pedalec usage but not by touring cyclists.
