a moped is a 49cc bicycle with an engine and pedal's,,mo=MOTOR,ped=PEDAL'S ,they were not built for speed just to get around town a bit quicker than a bicycle,
the modern moped(scooter) has a better engine build,reed valve's,a better exhaust system,, the older one's seem to keep on going,it's quite obvious they were built to last a good number of years,modern one's part's two expensive,and the prettier they are the more chance's they will be stolen........?
