We don't have floor to ceiling bike storage towers.

There are caged bike storage lockers for locked, communal shared space. Plus we have storage lockers outside of our condo unit but within the building where we store more bikes. I put 3 of my bikes there locked up. I have to keep my folding bike, folded because personal storage space locker is tight. He has managed to cram all 3 .his bikes in 1 storage locker space, with his folding bike folded. Plus he has a bike trailer-- ah yes, more dumping space for more stuff. He is very neat and organized about this storage space, so that he has enough rm. to maneouvre the bikes in and out.
