Yes. Iron turning into iron oxide(rust) is a chemical change.

Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.

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.
first physical, second chemical

Rusting is a chemical change, as steel/iron turns into iron oxide.

Yes, rusting is a chemical change.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
That'd be a chemical change, as steel/iron turns into iron oxide. Usually called rusting, or corroding.
