Let's put it this way because anyone can try it and maybe they'll like it: A 37 pound bike is not something I want to sling around stairs and trains every morning. A non-e 6-speed Brompton with fenders, rack and dynohub is pushing 30 and I think that's too heavy, but to each their own. Just make sure you know what you're getting with a folding ebike, is what I'm saying.
