Wow, nice link; thanks for sharing!

I think there must be a commercial outfit doing bike tours during the week, as I see groups which look like tour groups when I bike after work during the week. (The identical safety vests kind of stand out. :) ) The Mall/monuments area is such an easy place to ride, I'm surprised more people don't "do" DC this way!

There is a rental place at the Old Post Office Pavilion.

I did a bunch of the family rides on the mall with NPS and Trips for Kids a couple of years ago. They're excellent. You learn something new every time you go. The park rangers give a great tour.
