Is a rusting bicycle a physical or chemical change?
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.
What kind of change iron to rust?

Rusting iron physical change?
No. Rusting is a chemical change because the chemical composition is changed from iron to iron oxide. The iron reacts with oxygen in the atmosphere, forming iron oxide. Fe + O2 --> Fe2O3
