I have one bike on a hoist as linked to above, its my wifes bike and she doesn’t use it very often so its fine way up there.
But it would be a hassle if it was a bike I used daily, plus you need the height of the bike plus height of person plus an extra bit or you’ll be bumping your head on the bike.
I have 4 other bikes on the wall at two different levels. 2 higher up on this type of thing and two must frequently used bikes below on tusk wall hangers.
Works well as bikes are off the floor and are easy to access. But I do have a lot of height to work with in my garage.
