What's HN favorite fancy-ish ebike from the likes of VanMoof or Cowboy or something else? I saw one of the bikes sell for as high as $5k which, provided how many very nice-looking alternatives at 50% the cost there are seams unreasonable.
The Stromer range is very nice, super pricey, Klever as well.
I haven't tried or looked at other s-pedelecs. Regular e-bikes there are so many types and brands that it is hard to say what works and what doesn't without just trying them.
This store has quite a few brands of s-pedelec:

But I'd never buy a new one, I think they are simply way too expensive, it's just another bike with a small electric motor and these prices are ridiculous, you can buy cars for that kind of money.
