In my opinion, the bicycles are the best tranport in Viet Nam. First, it is very environmentally friendly, it doesn't have any smoke. Second, It's good for us and it's easy to go, We just need to get on the bicycle, put our feet on the pedal, try to balance for a while we can walk on the alleys in the street. Third, It is very easy to find, we can find it on the street stores, in the supermarkets ...ok, this is my opinion it should be right or maybe wrong, thank for listening.
