The original sentence uses the -ing form 'using' without an auxiliary, which is ungrammatical here. According to the list, this is a 'Verb + -ing form' issue (ID 8). The context is a general statement about habits, so the simple present tense 'use' is required. Also 'a lot of people' requires the plural noun 'bikes' rather than 'a bike.' Replace 'yes' with the more natural response 'so.' Suggestion: use simple present for habitual/general truths ('people use bikes'), and avoid using -ing without auxiliary unless forming a continuous tense ('are using').
