This piece from the Globe and Mail argues that a bikeable city is a livable city.
"For all the techno talk about magnetic levitation trains or personal rocket packs, the urban transport system of the future turns out to be bicycles. Sprockets and chains, seats and handlebars, this 19th century technology may be the best weapon we have for the long campaign to make livable cities in the 21st century. Bicycles take a fraction of the space and materials of cars or buses, are powered by the excesses of our calorie-rich diets, and have the huge advantage for those who ride them of extending both quality and length of life."
"If the arguments for increasing urban bicycle use are this powerful, why are so many cities having such a hard time setting aside guaranteed bike routes and lanes - making them the transport mode of choice, for work and leisure?"
