This document discusses cycling as a sustainable form of transportation. It first segments cyclists into groups based on motivations and bike preferences. It then examines the infrastructure needed to support cycling, like dedicated bike lanes and interconnected paths. Three case studies on cycling infrastructure in the Netherlands, Quebec, and Victoria, BC are provided. Key lessons from these examples include the safety benefits of separating bikes from vehicles, the value of connected networks, and the importance of government support through funding, planning, and integrated policies. Challenges to promoting cycling include political will, strategic planning, and integrating policies across areas like transportation and tourism.
