Eugene A. Sloane, the author of the 1970s Bike Boom bestseller The Complete Book of Bicycling, died in Illinois this weekend. He was 91 and died for complications from pneumonia, according to the Chicago Tribune.

Sloane published his first cycling book in 1970. It was followed by Sloane's Handy Pocket Guide to Bicycle Repair and Sloane's Complete Book of All-Terrain Bicycles.

Sloane's sons told the Times that their father had many interests that, variously, bordered on obsessions, including sailing, motorcycling and photography.
