How to create a cycling city? And is Amsterdam the real deal as the cycling capital of the world or not? Yesterday, Ruth Oldenziel kicked off the conversation with a guest lecture at the University of Amsterdam’s Summer School Grad Course Planning the City, where thirty scholars and practitioners from all over the world are studying these questions. These students were surprised to learn from Cycling Cities that Amsterdam’s history with cycling is checkered and almost an accident of history. The students learned about the five factors explaining why some cities cycle and others do not.
