We investigate the changes in the patterns of usage in the Divvy bikeshare system in Chicago from 2016-2018.

We use an iterative testing approach that is augmented by trend testing and a novel temporal false-discovery-rate correction. Results show stark geographical patterns in clusters that are growing and declining in relative bike-share usage across time and may elucidate latent economic or demographic trends.
