Picture of Wall mount bike storage
Wall mount with closet rod brackets found at my local home depot. Pieces of pine wood were used from a leftover kitchen shelf project to make a mini shelf on the top and to provide support when screwing into the wall studs. I put two little pieces of vynil tubing on the ''hook' part to prevent paint scratches. Project cost: about 10$

The bike was built by me.
Love this idea since I have loads of these brackets hanging around after installing new closet organizers!
