* Subject-verb agreement: The subject "you" is singular, but the verb "is" is used for plural subjects. The correct verb for a singular subject is "are."
* Word order: The sentence should follow a subject-verb-object structure. It should be "You ride the bus."
Here are some grammatically correct ways to express the same idea:
* You ride the bus.
* You are riding the bus. (If you are currently on the bus)
* Are you riding the bus? (Asking a question)
