Planetizen on a 'demographic crisis': "Why Bikeshare Doesn't Appeal to Low-Income Commuters"

In some locales around the country a solution for this problem is being sought. Here's an excerpt from the article in Planetizen:

     Bikeshare faces a demographic crisis. [emphasis added] Often a success where locals are wealthy, it has failed to take root in poorer communities of color, where a greater proportion of bike commuters live. "This is a glaring issue, critics say, especially in places where public money is being used to help bike share systems break even."
     Despite efforts by cities like Philadelphia to locate bikeshare stations in poor neighborhoods and allow payment by cash, the system has yet to catch on fully.
     Reasons for this disparity coincide with more general transportation challenges low-income neighborhoods face.
