A cyclist rides a Citi Bike in the East Village neighborhood of New York, U.S., on Tuesday, Oct. 11, 2016. Citi Bike, a three-year-old sharing program, began in 2013. With 110,000 regular members and another 500,000 day-trippers a year, it's expanding into new areas of Brooklyn, Queens and upper Manhattan, and will total 12,000 bikes at 700 stations by the end of next year, almost double what it had when it started.
