The Department of Transportation's Bureau of Transportation Statistics (BTS) has issued a technical brief on bike share stations in the U.S.

As of February, 2016, the U.S. has 2,655 bike share stations across 65 cities, which are recorded in BTS's Intermodal Passenger Connectivity Database, a nationwide repository of passenger transportation terminals.  This database provides the locations of U.S. bike-share stations and their connectivity levels to scheduled public passenger transportation modes and intercity and transit modes including bus, ferry, and rail.  Its findings include:

• Of the 2,655 bike-share stations, 86.3 percent (2,291) connect to another scheduled public transportation mode within one block. These connections extend the transportation network by offering a means for reaching places with scheduled public transportation, such as heavy rail stations and bus stops, and for reaching destinations not served by scheduled public transportation.
• Local buses are the most typical connection, with 84.2 percent (2,236) of bike-share stations located a block or less from a bus stop.
