　　Can you imagine a bicycle that has an iPhone on its handle and provides navigation tools and fitness information, along with data collectors that measure air pollution？This is just the beginning of the list of things that this dynamic new bicycle, known as the Copenhagen Wheel, is capable of.The biggest characteristic of this bike is its red hub (轮轴) on the back wheel, where the brain of the bike stores power, increases speed, monitors the rider's exercise, and collects data from the air and the environment.The data that is collected is put onto a public website so citizens can find out what their city's atmosphere is like during the day.

　　The Copenhagen Wheel comes to us from the Massachusetts Institute of Technology (MIT) in the U．S.A.It was developed by a part of MIT that is putting "intelligence" into everyday things that are a part of the infrastructure (基本设施) of our cities.Researchers from MIT chose the Copenhagen Conference on Climate Change to show off the new bicycle, and early feedback (反馈) was very positive.

　　The goal of the Copenhagen Wheel project is to promote (促进) cycling by lengthening the distance people can cover.In addition, the makers ensure the whole bike riding experience is smoother so that even steep (陡峭的) roads are no longer a problem for comfortable cycling.This new bicycle is also perfect for protecting the environment, and many big cities are making plans to encourage their citizens to use this two­wheeler when they go to and from work.The director of the Copenhagen Wheel project, Christine Outram, expects that this new bike will help lead the charge of smart transportation into the 21st century.She is fully convinced that many big cities will see the benefits of promoting this type of cycling to their citizens.
