Okay, my nearest bike shop seems to have Cube and Stevens bicycles. The Cube bikes look super nice, but are super expensive it seems. The Stevens bikes are too expensive, apart from this Stevens one, which seems super inexpensive compared to the others, but the frame looks kinda "fat":

I'm also still not sure whether I shouldn't just order online, but I think it's a bad idea because I have no idea what I'm doing.
My budget is "Please not more than 1300 Euros", but I'm not sure if that's even reasonable. I wish I could just get an old steel road bike for like 400 bucks, lol.
