I think bicycles are the best means of transport in VN on the account of convenience and good for health. Riding bike helps us reduce risk of getting cardiovascular diseases. Using a bike for transportation also can help us lost weight and improve health. In addition, riding bike won't make pollute. Those are some reasons why bikes are the best means of transport in VN. 

bicycles are the best means of transport in VN. in our modern stressful world we often forget about the old bicycle. nowaday car and motorbike with modern attached make us comfortabe and dont have to tired all day. but in my opinion, i think bicycle attached with all of VN customs and traditional.  the children in VN hve a time go to school by bike and it is like their friend with the expensive coast. its frienly with environment with no  modern attached
