so the company started using a fleet of box trucks to carry bikes between different kiosks every day. The kiosks also had some software problems in their early months. Problems included stations that did not accept payment information; kiosks where passersby could take bikes without paying because the bikes were not locked securely; and bike docks that did not work at all, forcing riders to travel to other stations. The deployment of a clean energy public transit system such as Citi Bike coincides with the sixth IPCC report on mitigation's call for an increase of modes of public transportation such as biking and walking. According to the report, "Case studies suggest that active mobility could reduce emissions from urban transport by 2%- 10% depending on the setting". Popularity Citi Bike's massive, unexpected popularity caused problems within a year. In January 2014, the designer of Citi Bike's bicycles and docking stations filed for bankruptcy protection. Officials with Montreal, Quebec-based Public Bike System Company (also known as Bixi) said they were $46 million in debt, partly because the operators of Citi Bike and Chicago's Divvy bikeshare had withheld a combined $5 million in payments because of software glitches in the docking stations. Alta officials, who operate Citi Bike, Divvy, and Capital Bikeshare in Washington, D.C., said they anticipated no interruptions of service, though they did want $20 million to expand the system to 10,000 bikes and 600 stations. However, due to Citi Bike's various problems, expansions to the Upper East and Upper West Sides were delayed for at least a year. Its general manager resigned in March. The new mayor, Bill de Blasio, stated that he wanted to expand Citi Bike's reach, but that he could not make city funds available for such an expansion at that time. Citi Bike workers joined Transport Workers Union of America Local 100 in July 2015. The company had about 200 employees joining the union at the time. On September 17, in the face of overwhelming support for unionization, Citi Bike agreed to recognize TWU Local 100's representation of Citi Bike's labor force. Expansion Reorganization On October 28, 2014, Alta Bicycle Share and NYCDOT announced a plan to improve and expand the Citi Bike program. Bikeshare Holdings LLC, a new entity formed by the partners at real estate developer Related Companies and gym chain Equinox Fitness, acquired Alta Bicycle Share—renamed Motivate—and named Jay Walder as the
