America may be a nation of drivers, but bike commuting is having a moment, a decade, perhaps more. Between 2000 and 2011, bike commuting grew by 443 percent in Portland, OR, 315 percent in Washington, D.C., and by 258 percent in San Francisco, according to the League of American Bicyclists. New York City may not have the highest percentage of commuters, but it does claim the title for the largest bike-share system in the country, with 600 stations and 10,000 bikes, not to mention more than 600 miles of bike lanes. But as photographer Sam Polcer’s new book, New York Bike Style, shows, the cyclists themselves — and their style — are a city treasure. Polcer, who regularly photographs cyclists in New York for his blog, Preferred Mode, shared a preview of his book with GP.
