Frankly this is as much of a recommendation as a review. I just recently got my sticky paws on a copy of Michael Edwards' The Tricycle Book and as it says on the tin the book covers early motor tricycles from 1895 to 1902. This volume covers French machines only, there is a part two on the way on the subject of British made tricycles and I am genuinely very much looking forward to it.
The Tricycle Book definitely falls into the 'boutique book' category and at GBP 80 plus postage represents a considerable outlay. However once you have seen it you have to concede that it is good value, the format is large and the publication luxurious. There are 364 pages and the book is very well illustrated mainly with photographs from the period. That Mr Edwards has managed to find quite so many early images is admirable, the majority of which are completely fresh to my eyes (and I do spend possibly more time than is healthy nerding away at early vehicles...)
Without doubt an authoritative work on the subject The Tricycle Book should be of interest to anyone with more than a passing interest in early vehicles. The righteous thing to do as ever is to buy direct from the author: https://surrendenpress.co.uk/the-tricycle-book-1896-1902
