Byrne is a committed cycling campaigner who takes bikes with him as he travels the world, mainly to the cities where his musical and artistic work takes him. When he has time off, he uses his bike - usually a full-size folding mountain bike he puts in a suitcase to travel on planes - to wander about and explore. It is this aspect of the book which most interested me, because he seems to be a practitioner of the derive, the engaged but directionless wander first proposed by the situationists as a suitable way to move through cities.
As the title suggests, the material for the book evolved in diary form over time, and the structure of the book reflects this. It is right, and true to the material, that this should be so, but it does mean that the various entries are of variable quality. Nevertheless, books of this kind, where an intelligent and engaged observer with a liberal agenda but no particular end in mind takes a close look at localities, are scarce indeed. In the hands of a travel writer, or a journalist, a totally different book would have emerged, but actually, this is the book I wanted.
