Hi dear,
Hanging bikes on pedals is not a viable storage option because it destroys the part of a wall where the bicycle is hanged.
The walls may crack and break. So, I would not recommend you to use pedal hangers to store your bicycle. One of my friends is storing his bicycle in a shipping storage container. You can ensure that your bicycle will be protected from rain and wind when you store it in a shipping container. You can even buy or rent a shipping container for the short term or long term.
Thanks!
