I pretty much keep them all in the bike cave although in years past there was some overflow. Several methods. Basic 2 bike stands where I alternate then front to back to fit the most in. Then I have a few on the wall hanging by simple pedal hangers I got off Amazon. One custom bike hanger with built in storage, a 3 bike display from an old bike shop and finally two hanging on a wall using some hangers I made with old handlebars and pipe fittings.


The basic room.


Homemade hangers





The front is hinged and then there's storage inside

This stand holds 3 bikes. You can widen it as needed to fit the bikes and the supports for the BB are reversible so you can face the bikes either way.


Back in the day (last year) I had over 30 bikes stored in this room. Got a bit nuts.
