Clean, Convenient, and Cheap

Traffic is the main cause of air pollution and noise in big cities. For example, drivers in New York are famous for honking（鸣）their horns and shouting. That noise drives many visitors and the local people crazy. Other big cities have similar problems with their traffic.

City governments have a lot of pressure to solve these problems. The most common solution is public transportation. New York's biggest form of public transportation is the subway. Another solution is bicycle sharing. This is a system that provides cheap bicycles. In cities that have bicycle sharing programs, there are lots of spots that have parked public bikes. People borrow the bikes and use them. They can return the bike at the same spot where they borrow it, or they can drop it off at another spot.

Bicycle sharing programs are different in each city. In some cities, the bikes are completely free. They aren't even locked. In other cities, you have to pay a small deposit（押金）. You get the deposit back when you return the bike. In still other cities, you need to have a membership with the bicycle sharing program. Once you have a membership, you can use a bike at any time you want.

Bicycle sharing is hugely popular all over the world. There are bicycle sharing systems in dozens of countries and hundreds of cities. In total, there are more than 530 bicycle sharing systems around the world, and that number is going up all the time.

People love this system. It can be great for connecting to other modes of transportation. It's quick to grab a bike when you need one and convenient to drop it off at any station. Bikeshare can also save a lot of money. The annual membership includes unlimited trips under 30 minutes. Whether you're using bikeshare to go to work or ride to meet friends, we bet you'll get there with a smile on your face. Getting places by pedal power gets great exercise. Even biking short distances can have positive effects on your health and stress level. Biking saves fuel, prevents carbon emissions（排放）and keeps pollutants out of the air. It's not only healthy for you, but also for the environment.
