It always grieved both me and my mrs that we couldn’t get the bike in the front room when I needed to work on it (to many sharp angles) and the kitchen is too small so I’ve always had to fix them outside. One of my mates used to take his bike up to his top floor flat (apartment) in the lift every night; fortunately he never got caught by the building supervisor.
All I can say to anyone whose mrs refuses to have the bike in the house is make certain that she’s worth the sacrifice of not having the bike where it should be, either that or run and hide when you get caught.
the other option is to sell the mrs and buy another bike.
