Biking in Amsterdam is popular. So popular that the Netherlands actually has more bikes inside the country than people. If this sounds strange to you, just think about the moment that you have a flat tire on your bike and can't get to work. What do you do? You hop on your spare bike of course! Not everyone has a spare bike, but to give you an idea, I live in a household of two, and we have three bikes---one for each of us and one spare one. It's kind of like the car situation in a lot of American households I know!
