I found this bike rack recently, and it works fine for normal bike wheels. However the other side has hooks that face out at about chest height.
The hooks are steel but are covered in black plastic tube to stop scratching.
The hooks were only about 12-15 cm long, so nowhere near long enough to hold a front wheel.
The brick wall is slightly misleading - the whole thing was about the length of a carpark, and it was mounted on 4 beefy caster wheels. There was a handle on the left end to pull the whole rack about, so its a moveable solution.
For what could the hooks on the far side be intended?
