I found many bicycle hook on Amazon.
(use keyword 'bicycle hook' for searching)
There are a lot of them with the price under 20$.
Some of them hook the bicycle to the ceiling, some to the wall.
From my experience, hook the bicycle to the wall is far practical than the ceiling.
Before you cleaned and painted on it, it looked like it passed through the world war.
After you fix, it become brand new! That's cool.
It would be perfect if you fix the leather part too.
