That makes it hard, but it seems like a really odd business case; are you doing something so unique or important that people will fly you in to do monitoring?

A bike box is maybe $300, and with a couple of tools you should be able to re-assemble a bike in maybe 5-10 minutes but then you are stuck with a box you can't take on the bike.

A brompton would fold down small enough you might be able to carry it onto the plane with you, but won't hit many of your other criteria.

I'd dump the list of "wants" and focus on what you actually need. The speed of a bike is mostly a function of the tyres suitablility for the surface and the engine (rider). A good rider on a 10" wheel Brompton will still be faster than a bad rider on a 700C road bike.

You're going to struggle with an 11-12" tablet on the handlebars, in terms of getting it to fit, being able to use it, etc. I'd try and find a way to avoid that. Do you really need a screen that size on the move or could you use a 5" phone and keep the tablet in a bag?

If it needs to fit on a plane, get a Brompton. If it doesn't, then just go into a local bike shop and buy a decent fitting hybrid. Ignore all the other details.

Don't touch a Eurobike, as you'll be safer and quicker walking.
