Hi again,
Just logged on again and seen everyone's replies - thanks for all the pointers and advice. For me both simple leads and more techie input is fine, because some of what I don't understand now may make more sense when I actually start using an electric bike. And it's great that people take the time to reply - I appreciate it.
I'm not on the ground floor, but have a lift, so that should be ok. I'm in London, and so will see what bikes I can take out for a test ride.
I don't know what the etiquette is about commenting on particular bikes on this forum, but I've seen this one online and if anyone has experience of it (reliability, ride quality) I'd appreciate your opinion.

I've been told about how good the Brompton is as a lightweight folder, but then have also read that the handlebars can flex strangely, and I don't know if converting it to electric would make that worse?
And also that most e-bikes have a tendency to get damaged around the brake handles for some reason?
Maybe the thing would be to hire one for a while and get some experience of it all. My budget isn't a lot more than £700, and I'm also open to a good condition second hand bikes.
Thanks again for the leads...
Best wishes and happy new year!
