It starts off well, with discussion of urban renewal in decaying American cities as seen from a bike. As the book progresses, though, it becomes less focused on biking and more on Byrne's own worldview and daily activities. Some of the topics he tackles are ambitious, but his research and writing don't prove up to the task, in my opinion. Also, a huge pet peeve from the book: when Byrne wants to talk disparagingly about the wealthy he uses the term "billionaires." I find this to be a rather conspicuous choice of language. The common vernacular would be "millionaires", but since Byrne himself is no doubt a millionaire, he uses "billionaires" so as not to make sophomoric generalizations about his own economic bracket.
