I have lived in the Netherlands, and while Cambridge is fairly walkable to say "Cambridge has excellent public transportation and is a biker’s paradise" is an absolute travesty and an indictment of the US as a whole. Public transit is acceptable if you live near the T, barely adequate for daily commuting if you rely on the bus, and there are only a handful of safe biking routes (e.g. by the Charles or along Alewife linear park).
