How Many Citi Bikes Are Actually Available? (Graph)

New York's Citi Bike claimed in September 2017 that it has 12,000 bikes in its system.  But as pointed out last month in Streetsblog NYC, there are far fewer (7166 at the time), likely because many are in repair or storage.  Or set aside for out-of-town commuters.

I've started logging the number of bikes in the Citi Bike system that are available, using Oliver O'Brien's invaluable Bike Share Map, which uses Citi Bike's data.  I'm using the Total Bike Available: Max Today metric.

As of October 28, the number of Citi Bikes available is up to 8592, a sharp jump from 7825 two days earlier.  This chart will continue to be updated.
