In telling the history of the Moulton bicycle, this book follows the intertwined lives of two very different men, both unusually creative, who had an extraordinary impact on each others' careers, given that they met, at most, three or four times, and never had a professional relationship of any kind.

In 1963, British inventor Alex Moulton (1920-2012) introduced an innovative compact bicycle. Architectural Review editor Reyner Banham (1922-1988) predicted it would give rise to "a new class of cyclists," young urbanites riding by choice, not necessity. Forced to sell his firm in 1967, Moulton returned in the 1980s with an even more radical model, the AM--his acclaim among technology and design historians owed much to Banham's writings. The AM's price tag (some models cost many thousands of dollars) has inspired tech-savvy cyclists to create "hot rod" compact bikes from Moulton-inspired "shopper" cycles of the 1970s--a trend also foreseen by Banham, who considered hot rod culture the "folk art of the mechanical era." The author traces the intertwined lives of two unusually creative men who had an extraordinary impact on each others' careers, despite having met only a few times.
