Back in early 2010, I reviewed David Henshaw’s excellent book Brompton Bicycle. There is now a second edition. This differs mostly in the second half of the book, with a rearrangement and expansion of coverage of Brompton’s future, customised machines, Brompton people and places, and how the bikes are made. The publisher details and price are as before, except that the new edition has a different ISBN: 978-1-901464-25-2.
The second edition is, if anything, even better than the first and is thoroughly recommended. My original review can be read here.
