I have an old Honda CB400. The starter is electric but you can still kick start it. I bought it when I lived in the middle of no where rural rust belt US. All roads were two lane and there was no traffic, riding felt safe.

I've moved and pretty much never ride now. I live in a small town but there is enough traffic to make me think twice. I take it out a few times a year and keep it maintained but riding it day to day would be suicidal.

I know you've mentioned moving to the country side or another country entirely but consider your area and traffic patterns before getting a bike. If you do decide to get one look in to dual sport types. I recommend Honda or Suzuki as they are cheap, parts are easy to get since they are so popular, and can be found in nearly every country.

I saw a comment on /pol/ a while back about crowd funding a warehouse to stock a ton of older Corollas, Civics, F-150s for the exact reason you mentioned. It really doesn't seem like a bad idea.

As far as EMPs, as someone in this thread said, I'd be more worried about the nuke that comes first.

Edit to add: If you've never ridden a bike before just get a Hayabusa, you'll be fine.
