I know most people here aren't massive retards about this, but one of the reasons I've been looking into the motorbike game is because there are far more vehicles out there that are extremely simple to repair potentially by myself and everything is analogue. I'm not that bad when it comes to vehicles and yes I do know that most vehicles currently do not rely on an internet connection DRM style to keep operational as of yet, but that may start changing soon as they keep pushing green agenda nonsense.
However with what we've seen being done to planes I'm going to play it completely safe because the elites are retarded they're probably going to be pushing people to buy electronic vehicles and this will have all kinds of ways to track your positional data as you're travelling through the country. So I'm just putting out a general PSA in that I wouldn't even get a vehicle that has digital display because that's one extra thing to go wrong that you're not going to be able to fix. Imagine having to ride several miles away just to get fuel and you realise you're fucked because an EMP device or something knocked out your digital display so you don't even know how much fuel you have lolz.
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.
Believe it or not with the bike I'm probably going to play it extremely safe, I grew up in Bradford so don't worry I know how to read traffic very well. I just need something that I can buzz around in so a low cc scooter is going to suit me just fine. If I'm really thinking the apocalypse will come along then yeah dirt bike, it's hilarious how cheap the bikes are.
I'm likely picking a 50cc scooter just because I won't shoot myself in the foot with insurance costs and like you point out bikes in general are very cheap when it comes to parts etc. if I do end up leaving permanently it will be very easy to have it shipped. I think I'm going ahead with this as a realistic plan because I am going to save a fortune on insurance as it turns out.
An extra plus point is that I could buy another bike and declare it SORN ( Yes, you need to do that in the UK Americans even if you're not driving it and just storing it ) and I can store it on my property no problem. Have that as a backup like I'm a fucking GTA player.
