I use to ride a bike for about a year, do you think my hymen is broken? Because people say that it does break during sports, cycling n etc.

Could be, do remembe. Any bleeding out of the ordinary after riding? If so, yes, if not, still could be. I am unaware of any statistics on hymen perforation in the virginal female, rates of people who have not had sex but whose hymen has been broken or perforated.
