I'm amazed at how few people can't seem to make room in a "tiny" apartment for a critical piece of transportation. My house is 840 square feet & I have 15 bicycles in it.
The trick? Cloud storage. All those random bits of who-knows-what that you don't use, haven't used in 6 months, or likely won't get used in the next 6 months goes away. Craigslist, FB Marketplace, Buy nothing, OfferUp, etc...If you, a common person own it, it's not special or unique & is likely ubiquitous enough across society that if ever you needed it again, it could be easily obtained at a cost far less than the cost and hassle of storing it for "just in case."
Purge that junk. You don't need a tarp to protect what's important. Keep what matters inside.
Circle of control.
