If a major EMP happens, you'll have angry hordes of people with no electricity, no work.
Your biggest problem is getting beat up and your bike stolen. Worse if your bike had Di2, the angry hordes will find it doesn't work and get even angrier and beat you up even more and also hurl painful insults at you for using Di2
Your best chance of surviving EMP is riding the ugliest, most cheapest looking bike you'll find and also wearing ugly clothes

Cross Check would be a good post apocalyptic bike. It's not ugly enough to be a great one I guess, it's actually fairly classy looking. But it's mechanically simple, has clearance to take a pretty big range of tires when they start getting hard to find, and you can roll over terrain my Cervelo is too dainty for.

In only a day this thread is showing some good entertainment value.
But to keep with the topic, of my bikes I think my 3 speed with drum brakes that is over a half century old will be the ideal bike. I bought it used in the 70s, it went into storage in the 80s when I was unable to buy the extremely odd size tires for it, but when 650b became a thing again I put new tires on it. Occasionally use it for a grocery store run.
When I bought it, I got the matching woman's frame bike with it, at that time I discarded that frame but kept the wheels and a few other parts as spares. Thus, I probably have several years of spares for it.
I might have to get it out today to take a photo of it.
If that happens, it will not be long before we all are wearing ugly clothes.

Doesn't everyone keep a pre 1973 Ford Bronco loaded up with old Stumpjumpers, beans, bullets, and bullion ready to go?

Magnetic pulse testing is not hard to do. Many EMC and test labs offer it. As with a lot of EMC issues, the sensitivity of the electronics is improved by reducing the loop area of the wiring. From what I've seen of the Shimano wiring, the loop area is quite small. On the other hand, I doubt that Shimano has put a lot of work into making their electronics tolerant of large electromagnetic fields, since there's no regulatory requirement for it.

When viewing footage from various disaster zones, it is very common to see a bicycle somewhere in the camera's field of view. After roads are broken by an earthquake, get covered by fallen tree trunks in a tornado or all side roads are covered in deep snow, it is often the bicycle that can still get you around. I.e., the question is not frivolous in situation where Ukraine shows how your life can get turned upside down overnight even in absence of any natural disasters. Radiation sickness? Even in acute cases, you may still have weeks to live during which you can take care of others.

I bought a couple of used DI2 component sets on eBay a few years back and tested them in my emp chamber. I have an array of supercapacitors that power an antenna inside a steel box. The box is a modified shipping contianer I use to store smoked deer meat, white rice, dried beans, and ammunition. I'm able to blast out almost a megajoule in about 30 picoseconds. It's a crazy intense blast. I remove the deer meat, rice, beans, and ammunition from the container for the tests.
