Interesting, but repetitive. Perhaps the book was compiled from a series of articles. I see one reviewer said, 'too UK centric', but the book omitted the Brompton. Also, the title is wrong: the 50 sections were mostly each about one bike, but not all. So, 'The History of Cycling in 46 Bikes or So and Some Other Stuff' would be more accurate. The author should have made up the number with the missing bike sections, or changed the title. A bit sloppy.
