Watch thousands of Citi Bikes flow into Midtown every morning and out again every evening, station by station
Each circle is a Citi Bike station. Blue means more bikes arrive than leave in that hour: the station is filling up. Red means it is emptying. The bigger the circle, the bigger the difference. The numbers are the average of the 23 weekdays of October 2025, about 155,000 trips a day.
Midtown, from 34th to 59th Street, has 143 stations. By noon on a weekday, how many more bikes are parked there than before dawn: about 200, about 1,000, or about 2,000?

What it shows
Commuters ride into Midtown in the morning and home in the evening, so bikes pile up where offices are and drain from where people live. A bike-share system that did nothing would end every morning with full docks in Midtown, where riders cannot return a bike, and empty ones in the neighbourhoods, where riders cannot find one. That is why bike-share systems must move bikes back: by truck, or by rewarding riders who ride against the flow. Traffic engineers call a daily pattern like this a tidal flow: the same streets carry the crowd one way in the morning and the other way at night.
