partnership operated by NYC Bike Share LLC, a wholly owned subsidiary of Alta. The system, which was first supposed to start in fall 2011, got pushed back to summer 2012 due to uncertainties about where to place the rental stations. The city had originally intended to place Citi Bike stalls mostly on sidewalks and public plazas, but there were some locations where stalls would take up parking spaces. The 2012 implementation date was only for Phase 1 of Citi Bike, with more phases to come later. Software problems delayed the planned start until March 2013. These problems were also reported by Alta programs in Chicago and in Chattanooga, Tennessee. The problems reportedly occurred because the Public Bike System Company, a Canadian affiliate of Alta, was involved in a dispute with software supplier 8D Technologies. Then, Hurricane Sandy damaged 1,000 bicycles and 60 stations in storage at Brooklyn Navy Yard. As planning progressed, some residents expressed dismay at the lack of docking stations in their neighborhoods while others fought against stations on their blocks. Deployment Citi Bike finally began operations on May 27, 2013, with 332 stations. The stations were located in Manhattan south of 59th Street and in Brooklyn north of Atlantic Avenue and west of Nostrand Avenue. Officials said the system opened with 6,000 bikes. At the time of implementation, it was the largest bikesharing program in the United States. When launched, the system was slated to expand to 10,000 bicycles and 600 stations in Manhattan south of 79th Street, plus stations in several Brooklyn neighborhoods, including Greenpoint, Crown Heights, Bedford-Stuyvesant, Park Slope and Carroll Gardens as well as parts of Queens. At first, the timeline for the expansion was not made publicly available, but it was later announced that the expansion would be complete by the end of 2016. There has been increasing interest in further expansion across New York City; for example, in June 2013 a Brooklyn politician opened a petition drive to accelerate deployment in Greenpoint. In contrast, the May 2013 installation deliberately bypassed South Williamsburg. Throughout the first year, there were more than 100,000 registered members who rode over , including 70,000 members in the first three months alone. On August 6, 2013, riders took 42,010 trips, the largest single-day total for any North American bike-sharing system. In Citi Bike's first few months, some kiosks docked too many bikes while others did not have enough,
