英語の原文（Wiktionary）
Borrowed from French bicycle (modern bicyclette), from bi- (“two”) + cycle (“cycle”). By surface analysis, bi- + cycle. First attested in English in 1868, and in French in 1847. (promiscuous woman): From double meaning of ride ("to transport oneself upon" vs. "to mount someone to have sex with them"). A communal bicycle would have many riders.
