Catholicism, literature, sex, thieves, and Henri de Toulouse-Lautrec each rate an entry in “Cyclopedia: It’s All About the Bike’’ (Chicago Review). Longtime cycling journalist William Fotheringham packs this grab bag with wacky characters, heated debates (is sex good or bad for racing performance?), and trivia (England in the early 20th century had bike-powered generating stations). He decodes cycling slang and weighs in on magic remedies for racers. Boston is rightly proud of its new bike-rental scheme, but Fotheringham will tell you that the city has a long way to go to catch up with Paris, which now has 20,000 bikes in circulation.
