Mopeds are all essentially motorized bicycles, in fact the word "Moped" is short for Motor Pedacycle. Despite being so closely related, motorized bicycles and cyclemotors they are quite different from the modern moped. In most cases these were small low powered gasoline engines that were added to adapted standard bicycle frames. These machines were rather primitive, many lacking decent braking systems, lights, or suspension. Often these bikes were constructed from engines sold in kit form rather than a complete cycle. These motorized bicycle kits were low cost options for people who couldn't afford a factory motorcycle or moped.
