Motobécane was a French manufacturer of bicycles, mopeds, motorcycles, and other small vehicles, established in 1923. "Motobécane" is a compound word made up of two colloquialisms stuck together. "Moto" is a slang word for motorcycle; "bécane" is slang for "bike."

In 1981, Motobécane filed for bankruptcy, and was subsequently purchased by Yamaha and reformed in 1984 as MBK; the French company continues to make motorscooters, and has no relation to Motobécane USA, which imports bicycles from Taiwan and China, manufactured to their specification under the Motobécane trademark.
