Ride a bicycle, in Bangkok, when its hot and about 30 degree and more, are you crazy?
For sure, it is not the first choice when you want to go to another place. The temperature in Bangkok is hot, the whole year, so people must be crazy when ride a bicycle. But you will be surprised, there are some people who enjoy to ride a bicycle.
There are at least three kind of people who enjoy to ride a bicycle: people who wants to keep some money, the fee for rent a bicycle is low --- people who like to make some sports :-) --- and people who like to make a tour, for example at the river Chao Phraya's shore are some nice routes for a ride.
