× Yes, I used to own 2 bikes when I was a child which my mom bought it for me when I was like 5 or 6 years old and I really enjoy writing bikes every day after school.
✓ Yes, I used to own two bikes when I was a child, which my mom bought for me when I was about five or six years old, and I really enjoyed riding bikes every day after school.
Errors addressed: plural spelled as numeral (use words in formal speech is optional but not grammatical error) and wrong verb forms. Specific issues: 'bought it for me' has an extra object pronoun 'it' because 'bought' already takes 'for me' as indirect object; remove 'it'. 'Enjoy' should be past tense 'enjoyed' to match 'used to' (habit in the past). 'Writing bikes' is incorrect word choice and form; the correct verb is 'ride' and the gerund 'riding' is required after 'enjoy(ed)'. Suggestions: remove redundant pronoun 'it', use past tense consistency for past habits (used to -> enjoyed), and use the correct verb 'ride' with -ing form after 'enjoy(ed)'.
× That's how I learned how to ride bike as a child.
✓ That's how I learned how to ride a bike as a child.
This sentence misses the article 'a' before the singular countable noun 'bike'. Also the phrase 'learned how to ride a bike' is correct; keep 'how' only once is acceptable but 'learned to ride a bike' is slightly more natural. Suggestion: add the indefinite article 'a' before 'bike' or rephrase to 'learned to ride a bike' for conciseness.
× Yes I think bikes are popular in my country because it used to be one of the most common types of vehicle back in the in the days it it is cheap and eco friendly especially in big cities like Hanoi.
✓ Yes, I think bikes are popular in my country because they used to be one of the most common types of vehicle in the past; they are cheap and eco-friendly, especially in big cities like Hanoi.
Multiple problems: pronoun reference and tense consistency. 'It used to be' incorrectly refers to 'bikes' (plural) using singular 'it'; use 'they'. 'Used to' indicates past habit, so 'used to be one of the most common types of vehicle' is fine but needs plural agreement. 'Back in the in the days' is redundant and ungrammatical; replace with 'in the past'. Run-on sentence: two clauses need separation; add semicolon or conjunction. 'it it is cheap' duplicates 'it' and mixes tenses; change to 'they are cheap' to describe a general present truth. 'Eco friendly' should be hyphenated as 'eco-friendly'. Suggestions: ensure subject-pronoun agreement (they), remove duplicated words, keep tense consistency (past for historical prevalence, present for general qualities), and fix punctuation to avoid run-ons.

This repeats the earlier pronoun issue: 'it' is incorrectly used to refer to 'bikes' (a plural noun). Use 'they' for plural agreement. Also remove duplicated words 'in the in the days' and duplicate 'it'. Suggestion: always match pronoun number to its antecedent and proofread to remove word duplication.
