Many US buses have a bike rack on the front that can hold 2 or 3 bikes which allows for easy bike-bus travel. I don’t think bringing the bike inside the bus is an option anywhere.

I've never seen these in Europe. I suspect they are incompatible with the much stricter pedestrian safety rules.

In Copenhagen if someone needs a bike at both ends of their journey (not very common) they might own two, and leave one at the station.
