The word moped was coined by Swedish journalist Harald Nielsen in 1952, as a portmanteau of "motor" and "pedal". It is however often claimed to be derived from "motor-velocipede. According to Douglas Harper, the Swedish terms originated from "(trampcykel med) mo(tor och) ped(aler)", which means "pedal cycle with engine and pedals" (the earliest versions had auxiliary pedals). Like some of the earliest two wheeled motorcycles, all mopeds were once equipped with bicycle pedals.
The name "moped" has now been applied by some regional governments to vehicles without pedals such as motor scooters, based on criteria of restricted engine displacement, speed, and/or power output. This is a misnomer, as they are no longer "mopeds" at all, and might instead be called a "noped" if they appear to look exactly like a typical moped, but no longer include pedals.
A lightweight motorized bicycle that can be pedaled as well as driven by a low-powered gasoline engine.
1950s: from Swedish, from ( trampcykel med) mo(tor och) ped(aler) ‘pedal cycle with motor and pedals’.
