What is the difference between Moped and Scooter?


Moped
A moped is a cycling vehicle equipped with pedals and low power motors to provide economical transport. The term moped comes from cycling pedals, which rider drives the vehicle and starts the auxiliary motor. Most countries divide a two-wheeled car into two rounds, with engine displacement below 49 cubic centimeters. Some countries need to pedal with their feet.
Scooters
Motor-scooters can be distinguished by chassis and foot pedal platforms. They are usually driven by a small motor, ranging from scooter 50 cc to 650 cc. Scooters are typically run on a 10-inch-diameter ferry. The model of the Scooters is Honda's Activa, Yamaha's Ray, Suzuki's Access and the famous Italian scooters from Vespa.
ROCKET 50cc Scooter
Technical Differences
Mopeds and scooters both use small motors to propel. However, a moped's motor is designed to assist cyclists, and only provides part of the locomotive energy. A scooter uses its motor to provide all the propulsion force, all the time. This scooter uses electric and charging systems, which can power the lights and ignition systems and recharge the batteries. Mopeds may be equipped with a basic power system, but many can still ride with a pedal. Mopeds can use small diameter or large diameter wheels, such as 36-inch bike wheels. Scooters use only small diameter wheels with a maximum diameter of 12 inches.
Legal Differences
Most countries classify mopeds as motorized bicycles and do not require the moped to be registered. However, the rider must have a valid driver's license. Scooter is classified as a motorcycle, requiring registration, motorcycle-endorsed licenses, and in some countries, insurance. Mopeds are generally restricted in speed and engine displacement, with most states limiting engine sizes to 49 cc or less and maximum speeds of 30 mph. Some, however, allows moped engine displacements up to 130 cc. Scooters aren't limited in maximum speed or displacement.
Cultural Differences
Scooters and mopeds have long been entrenched in Europe's heritage, providing transportation to much of France, Spain, and Italy. The moped moniker is commonplace and refers to many of the scooters and true mopeds that ferry people across many European cities.
These days moped is generally applied to any 50cc two wheelers but originally it was a bike with a small engine but also push bike pedals. Initially these were tiny engines mounted to normal pushbike frames or even within wheel hubs allowing the cycles to be pedalled reasonably normally however as the bikes started to be designed more and more specifically toward powered transport this aspect became less and less practical. The pedals became just a way to start the engine, this was hard work so some bright spark came up with the kick start which was less work and the moped was no more. Of course, later some even brighter spark came up with electric starts and kickstand went the same way (and yes, I know, that's oversimplified.).
Some definitions of scooter also require a platform for the rider's feet and hence would exclude step throughs like the Honda which have footpegs, this might be a regional thing as certainly when I was growing up we'd describe them as scooters in the UK.
They're pretty much the same thing these days although the term moped usually refers to the low powered, like the 50cc scooter. I haven't seen an actual moped for a while now. They used to be more common. They were a hybrid of a bicycle and a motorbike (the mo part of the word moped). Basically, they were motorized bicycles, you'd pedal to get up to speed and then the motor would kick in and keep you cruising.
Scooters on the other had been just like your Vespa type thing, no pedals, just a funny looking motorcycle, normally with no gears, just a twist and go deal. Nowadays though people kinda interchange the words depending on who's speaking.
Megamotormadness offers a variety of scooter styles with many color options. Whether you are looking for a reliable transportation alternative or just a fun ride around town, we have something to offer. Our Scooters / Mopeds are stylish and affordable. You will get the quality you need with the motor scooter prices you want. All scooters are backed with warranty and our parts department is ready to serve your requests.

50cc moped runs great until full throttle then boggs down-does not do it at 1/2 or 3/4 throttle


Check for good fuel flow to carburator. If so have a qualified technician look in the carb for debris blocking the main jet. this is very common when the vehicle sits for an extended period of time.
