There is no set age. The Bill of Rights applies to every person visiting, living in or being a citizen of the United States of America. However, minors have some restrictions. For example:
1st Amendment: Freedom or Speech, Press, Religion and Petition.
You are free to choose your religion, be it Atheism (technically not a religion), Christianity or Islam, to name a few examples. They can, however, force you to go to church (or another holy place) even if you don't want to.
2nd Amendment: Right to Keep and Bear Arms.
Minors may not legally own firearms or explosive devices of any kind (guns, fireworks, grenades, etc.)
Those are just a few examples of how minors are a bit limited (1st Am. may have some good reasons, 2nd Am. DEFINITELY has a good reason for restrictions).

Incorporation
While it is generally believed to apply to all levels of government, in actuality, the Supreme Court has never determined if the Bill of Rights applies to all states, as well as the federal government. The powers of the Bill of Rights were expanded to support the Fourteenth Amendment's wording that no state could withhold the rights outlined in the Bill of Rights.
