Wouldn’t 3k Euro be essentially the luxury sedan of ebikes? My first was a class 1 aimed at tourist rentals that cost around $1.5k CAD ($1k Euro). I considered that entry level at the time, though there are cheaper ones out there now. My current one is a $2.5k CAD ($1.7k Euro) class 2. It is pretty much everything I could want in a bike. I can’t see myself spending more. Well, maybe a cargo model would cost more?
I get what you’re saying about theft though. I am lucky in that I have indoor parking both at home and work. A coworker of mine lives in a condo where he can’t park a bike indoors. So while it was thankfully never stolen, he was sufficiently nervous about it that he eventually sold his and replaced it with an escooter.
