As much as people point to Amsterdam as the model for bicycling, Richard Layman makes the point that Copenhagen is a more apt model for DC.
The thing is that Copenhagen lost its bicycling culture. They reconstructed it. That's the city to which DC should look to as a model for expanding the use of bicycles.
The city with the sixth-highest quality of life in the world is also home to the world's most successful community bicycle program. In Denmark practically everybody has a bike, and for many years Copenhagen has been known as 'the city of bikes'. The city of Copenhagen plans to double its spending on biking infrastructure over the next three years.
Currently 32% of workers bicycle to work and 50 percent say they cycle to work because it is fast and easy.
