It depends on your situation but if it's apropos maybe the following. Apartment buildings sometimes have a built in version from the roof.
Make a simple lift like they use to lift furniture into apartments. Basically a rope out the window with a triangular three pole that extends the roipe away from the outside wall, with a pulley on the end.

The triangular three legged pulley holder could be put out of a large window or patio.

I have seen a similar thing used at a university where you put a coin in a lock and this releases the front wheel holder which you attach to the bike wheels to pull the bike up the wall for locking it to the wall. Sort of like a lock box. You bring it back down by putting the key in the lock to release the wheel to be lowered down. Hard to explain but easy to figure out when you see it.

This is a very complex version https://www.wired.com/2011/04/bike-h...-of-buildings/
