Quite an impressive list!  The smallest city listed Davis, with 65,000 residents.  The largest is Berlin, with 3.4 million — where less than half the residents own a car!  This list demonstrates that cities of all sizes can make bicycling a core component of their transportation infrastructure.  Kudos!
