* Pronoun Usage: The pronoun "it" is used incorrectly. It's referring to the bicycle, which is a thing, not a person.
* Subject-Verb Agreement: The sentence structure suggests you're asking about the bicycle's ability to use pronouns correctly, but the verb "is" doesn't make sense in this context.
Here's a better way to phrase the question:
* "Is that bicycle using pronouns correctly?"
This sentence uses the correct pronoun ("it") and the verb "is" agrees with the subject "bicycle."
