Europe
Amsterdam
The “bicycling capital of Europe” tops many lists—including this one, it seems—as the most bike friendly city anywhere. Safe and extensive route networks, serious governmental promotion, and a bike culture that transcends class boundaries are all reasons why 40% of the city’s traffic moves on two wheels.
Barcelona
Barcelona’s Bicing program, one of many mass bike rental systems that have popped up recently in Europe and beyond, debuted in 2007 in the Catalonian capital. An annual Bike Week is held in late May to spread the word.
