Do you think bikes are popular in your country?

I do because a lot of my friends are riding it and I can see many adults riding it to work. Therefore I think it's quite popular.
Did you have a bike when you were a child?
점수: 75.0제안: Your answer is correct and natural but too brief. To improve, give a short topic sentence followed by 1–2 specific supporting details (where you rode it, who gave it to you, or how often you used it). Use one linking word if you add details and keep total to under five sentences.
예시: Yes, I did. I had a small blue bicycle that my parents bought me for my eighth birthday, and I used to ride it around the neighborhood every afternoon. Because the area was quiet, I felt safe practicing new skills like riding with no hands.

점수: 82.0제안: This answer is relevant and gives reasons, but could be more natural with improved grammar and smoother linking. Start with a clear topic sentence, then add specific examples or comparisons. Use linking words like "because" or "for example" and avoid tense/number mismatches (e.g., "my friends ride them" not "are riding it"). Keep to under five sentences.
예시: Yes, I think bikes are quite popular in my country. For example, many of my friends ride bikes to school, and I often see adults commuting to work by bicycle, especially in the mornings. Because cycling is affordable and helps avoid traffic, more people choose it as a daily transport option.
× I do because a lot of my friends are riding it and I can see many adults riding it to work.
✓ I do because a lot of my friends ride them and I can see many adults riding them to work.
The original sentence uses 'are riding' which implies a continuous action now; the question asks about general popularity, so the simple present 'ride' is more appropriate for habitual actions. Also 'a lot of my friends' is plural, so the pronoun should be 'them' not 'it'. Change 'are riding it' to 'ride them' for correct habitual aspect and pronoun agreement. Additionally keep 'riding them to work' for adults since 'riding' as a present participle is fine describing what adults do habitually.

✓ I do because a lot of my friends ride them and I can see many adults riding them to work.
The noun 'bikes' is plural in context, so the pronoun should be plural 'them' rather than singular 'it'. Using 'it' creates a pronoun-antecedent agreement error. Replace 'it' with 'them' to match the plural noun.
