Keep in mind friends before buying second hand bike that some bikes are may be good condition or bad condition. Just check it before buying why I am sharing this experience because I had also purchased second hand bike in my life . And I have suffered various problems with my second hands bike.every second hands bike means that well not in good condition.
So my friends please keep in your mind that you just check all function are doing perfect or not.otherwise your value of money well waste. Buy any thing but its has to be advantages for you.
