Most cities have the bits and pieces of good places to ride bikes: A path along a river, some appealing neighborhood streets and maybe a protected bike lane. The trick, though, is to move from individual projects to connecting a biking network that allows people on bikes to travel anywhere in the community without needing to think much about how they will get there. While every street won’t be bike-friendly in the short term, linking a functional bike network is within reach in many places.
