English composition: If you live in a big city like Beijing and Shanghai, what kind of transportation mode would you choose and why?

If I live in Shanghai, I will choose my bicycle as my means of transportation. As we all know, Shanghai is a big city with heavy traffic. If you choose a private car, bus or taxi, you will choose to wait because of the most common scene: traffic jam. Although the bicycle is very tired, it is more convenient and faster. When you breathe outdoors, you can play with the wind and the sunshine. Riding a "green" bike, I believe I can enjoy a relaxing trip.
