Capital Bikeshare is out with a new survey of its users, and things are pretty rosy in the world of the bike-sharing service. Users are opting more for Bikeshare trips over other forms of transportation, and their most serious concern seems to be getting more stops.

Bikeshare members think that a Bikeshare membership means a big help for their wallets, reporting an average of $800 yearly savings in transportation. Riders were positive about aspects of the service—-the worst-rated feature was nighttime lighting at stations, and even that received positive ratings from 55 percent of respondents.

One problem persists for the service, though: It’s not reaching all of D.C. Bikeshare users—-or at least those that responded to the survey—-are different from the average Washingtonian. They’re younger, more likely to be male, and better educated than the average District resident.

Bikeshare users are also whiter than the rest of the city—-the survey notes that only 3.5 percent of users of the service are black, while black people made up 50.7 percent of the city’s population in the 2010 census. Ward 7 residents make up only 0.8 percent of users, while Ward 8 is even less represented, at 0.4 percent of users, a demographic disparity that drew the ire of Reason Magazine libertarians last year.
