I think 2000€ ($2200) is about right. That gets you a Brompton C Line and all the accessories you need.
Or it gets you a perfectly fine road bike, gravel bike, or hardtail mountain bike, if those fit your riding style better.
With road bikes, you can spend obscene amounts of money chasing marginal weight savings. I will never understand spending $10000 on a road bike to save the amount of weight you lose by pooping.
I am willing to spend a lot more on a mountain bike. Good full suspension and robust wheels with high-engagement hubs hits $5000 easily.
It was Mitch McConnell and the Republics that blocked Merrick Garland, not the Democrats.
