Yes, I have 2 hooks at differing heights and holds my mountain bike just fine mounted to a brick wall.
The Vinyl-Coated Screw-In Heavy Duty Steel Wall Mounted Bike Hanger in Black 50 lbs. has a working load limit of 50 pounds.
The suggested pilot hole size is 5/16 in.
This wall mounted bike hanger can be mounted vertically into a stud.
Using this as a swing is not recommended.
It's a screw into wood type screw. Finding a threaded nut for it would be a bit challenging.
If you can find a stud, you can mount these no problem. Please, please, PLEASE don't screw them into drywall and hope for the best. You could mount a 2x4 horizontally across multiple studs, paint it either to accent or to blend, and then mount these hooks into the wood. One more word of caution - sometimes apartments use metal framing instead of wood framing. Mounting into a metal stud will NOT work! Good luck!
I “wood” ;)
