The best method to prevent rusting when storing Bicycles is to store the Bicycle in a Shed or Garage, away from Weather and the Elements. If you have to store the Bike outdoors, you can buy a Tarp that will provide insulation and protection from Rain.

It's not the rusty bike it's the rusting of the bike. rust forms in a process called oxidation, or when iron comes in contact with oxygen. Also one reason you can tell it's a chemical change is when you can't reverse the process. Or when it involves changing the chemical compound.
Yes. Iron turning into iron oxide(rust) is a chemical change.
To keep moving parts moving with minimum resistance, and to prevent exposed metal parts from rusting.

Rusting is a chemical change, as steel/iron turns into iron oxide.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.
