I bought this book as a source of inspiration and ideas, a quick way to tap into a vein of 'wonder' in cycling culture in all it's shapes and forms. Where does function end? Where does 'style', self expression and 'quirks' fit within cycling 'culture'?
I don't think I'd recommend this as a reference on design, in respect to engineering or even any real depth of information (there is a lack of background information, which is a little frustrating at times); but the pictures capture more than just the objects, the also capture the people (and for me) a little of the 'spirit' that is the freedom of cycling.
If you approach this as s 'coffee table' book, a 'talking point'(?) and as a taster, then you'll not be disappointed. It's already sparked some serious discussion about frame shapes, bar designs 'urban cyclists' in my household.
