Unsure how credible this list even is. Here's the "methodology":
HOW WE CHOSE THE TOP 50
The statistics and descriptions here represent just some of what we consider when compiling this list. For example, we also mine U.S. Census data for such factors as overall percentage of bike commuters in each city and the rate by which that number is growing. We catalog the amount and quality of cycling infrastructure in each city—including miles of protected bike lanes and roadways marked with sharrows—and how recently it's been implemented. We rely on data collected by national advocacy groups like the League of American Bicyclists, the Alliance for Biking and Walking, and People for Bikes. And, most importantly, we talk to local advocates, officials, and everyday riders in each city on the final list, as well as those that didn't make the cut.
So... not exactly rigorous. Nevertheless, feature
