Rapha City Cycling Guides
The set features eight small guide books - covering Antwerp & Ghent, Amsterdam, Barcelona, Berlin, Copenhagen, London, Milan and Paris. Each one is densely packed with information for the cycling tourist, or the touring cyclist, or even just any old tourist to be honest. They each have a short introduction to the city, and feature a mapped day-ride that takes you round the main parts of the city, before diving in to more detail on a few specific neighbourhoods. They're written and designed by Andrew Edwards and Max Leonard.
By way of example, with the London guide you're given detailed information about Soho & Mayfair, Shoreditch, Borough, Notting Hill and Hampstead - including shopping, eating, stuff to see and do, and of course a few bike shops and cafés.
At the back of each book there's also a great (and detailed) guide to the cycling habits of the city you're visiting - invaluable when you consider the starkly different riding habits of Londoners, Milanese and Parisians.
Each book is illustrated by a different local illustrator: Amsterdam is by Joost Stokhof, Antwerp & Ghent by Sebastiaan van Doninck, Barcelona by Judy Kaufmann, Berlin by Mikkel Sommer, Copenhagen by Simon Væth (pictured below), London by Henry McCausland, Milan by Riccardo Guasco, and Paris by Louis Thomas.
The Rapha website also has a set of additional ride routes for each city which you can download to your bike's GPS thingamajig if you have one.
Very lovely, and, given that these are produced by Rapha, surprisingly affordable at £25.
