I prefer wall mounts (vertical from front tire) for ease of access. Ceiling mounts or leaving them on the floor always leads to a game of musical bicycles. And even though my bike is light and I'm relatively tall, the ceiling mount is a huge pain if you use the bike regularly.

We have a couple of these. They are so easy to use, and stay put well. But also easy to move around when we want to.

Thanks where did you find those or what is the brand?

Our first one I just found on a local FB Marketplace. We bought a second one online. The one I showed you, I just googled To find an image. It was probably from This Racor site.

Thank you!!

I'm counting at least three. Would hang them up underneath wall to wall (at least head high) shelf attached to that back wall. There are different kinds of metal hooks you could use. Would begin with strong eye hooks beneath the shelf spaced where needed and then use "S" shaped hangers beneath that to hold the different sized/weight bikes at the height where you want/need them to be.

If you put a board flat against the wall beneath the shelf (between any support brackets or to which you attach the brackets), that offers a lot more options for hanging space as does using different kinds of hooks for specific purposes.

With little kids, the bikes should be on the floor.

My friend stored her bike from the ceiling. We were always bonking our heads on it.

Something to keep in mind... The more difficult you make it to get to a bike, the less you will ride and benefit from improved health and enjoyment.

I assume you have a garden? Isn't there some place where you can put a shed? It will be the best way to store your bikes
