New York Citi Bike riders are at risk according to a new audit exposing spotty maintenance checks, poor cleanliness and defective docking stations. Comptroller Scott Stringer released his report Thursday looking at if New York City Bike Share, which manages the scheme, is in compliance with its Department of Transport contract. According to maintenance data, only 28per cent of the 6,000 two-wheelers in Manhattan and Brooklyn were inspected in November 2013, 34per cent in December 2013 and 38per cent in January 2014.
