Philadelphia was rated by a website the ninth most "bikeable" city in the United States and tops among cities with populations of more than a million, city officials said Friday. Walkscore.com's rankings were based on bike lanes, hills, destinations, and road connectivity, among other criteria, city officials said. Census Bureau data show that more than 2 percent of Philadelphians bike to work. The data also rank Center City and South Philadelphia as among the top 25 biking neighborhoods in the nation.
