Its a combination of reasons: - Netherlands is compact (10km from town to town, bikable) - Netherlands is flat - Cities are old, and are not easy to navigate with cars - Cars are expensive - Infrastructure is in place (everywhere!) - Bikes are cheap - Biking is healthy - Biking is often faster in cities for <10km distances (better routes, no searching for parking place) Note: If you want bikelanes in your city/country: Just start biking, the more and more people are biking, the more politics is forced to build infra. This is happening in Paris, Latvia, and more!
