1. What is a Scooter?

   Well, here’s what Wikipedia has to say:

   A scooter is a style of two-wheeled motor vehicle traditionally defined by characteristics such as a step-through frame, wheels less than 16″ in diameter, and an engine located below the rider and to the rear.

   That pretty much sums it up. Motorcycles have an engine mounted in the middle of the frame with a gas tank above it. The rider sits astride the engine with the gas tank right in front of them. Motorcycle wheels are also typically larger (over 16″ diameter) than those on a scooter. Another major difference is that the engine of a motorcycle is attached to the frame, while on a scooter it is usually part of the rear suspension. So when a motorcycle rear wheel goes up and down, the engine remains stationary, while when the rear wheel of a motor scooter goes up and down, the whole engine and transmission moves up and down with it.

   These days, 99% of scooters have a “twist and go” automatic (CVT) transmission, which means you don’t have a clutch to control and you don’t have to change gears, while 99% or motorcycles have a manual clutch and you have to shift gears manually (with your left foot). This also means that on 99% of motor scooters you apply the rear brake with your left hand, while on 99% of motorcycles you apply the rear brake with your right foot. While there are still a few manual scooters and there are a few automatic motorcycles, both are very much the exception rather than the rule.

   These differences result in a motorcycle usually having better acceleration high speed handling characteristics, but a motor scooter is often more maneuverable at low speed and is easier to ride, especially for novices.

   Scooters usually have a small engine, from 50cc to 250cc, though there are 400cc and even 800cc scooters, so engine size doesn’t define them. While most are limited in speed, scooters with a larger engine can exceed 100mph and cruise easily at freeway speeds, so speed isn’t a defining characteristic either.

   So what is a moped then? That’s a little trickier, but the working definition for most DMVs is a motorized two wheeled vehicle with an engine of less than 50cc capacity. It used to be that a moped was a Motorized pedal cycle, i.e. basically a bicycle with a small engine, but some jurisdictions don’t require pedals. Again we can also look at Wikipedia for a definition:
   Mopeds are a class of low-powered (under 50cc displacement) motorized vehicle, generally two-wheeled. A Moped is driven in an upright position with the rider’s back perpendicular to the seat . From a practical point of view, in most jurisdictions mopeds can be ridden without requiring a motorcycle license (a car license is sufficient). They may be speed limited by design, but even if they aren’t, the small engine size usually limits then to a top speed under 40mph (maybe 45mph downhill with a tail wind). In the United States the definition and regulation of mopeds differs from state to state. Again calling on Wikipedia:

   Legal terms and definitions of low-powered cycles vary from state to state and may or may not include “Moped,” “Motorcycle,” “Motorized Bicycle,” “Motorscooter,” “Goped,” “Motor-Driven Cycle,” and or others. A moped’s speed generally may not exceed 30 mph (48 km/h) on level ground, even if it is capable of going faster. In a few states this number is 20 or 25 mph (32 or 40 km/h), and in most states, the maximum engine capacity is 50 cc. However, Kansas (“Motorized Bicycle” K.S.A. 8-126, 8-1439a) allows up to 130 cc[13]. Some states, like California, require pedals, while others do not. Virginia allows mopeds to operate at up to 35 mph (56 km/h). Some states, like North Carolina, require there to be no external gear-shifting mechanism.

2. The fact is, scooters are like any other piece of sporting equipment; they can be used and used safely, but you need to take proper precautions. Here are a few easily digestible guidelines for scooter safety that everyone who uses scooters should observe:

   1. Always wear safety gear: Helmet, Elbow Pads and Knee Pads. This is a small investment, but necessary- only about $30- can instantly eliminate almost two-thirds of possible scooter accidents. In many states, provinces and regions throughout the world, these are required by law!

   2. Always ride your scooter during the daytime. When it is dark out, there are just too many things that can easily upset your balance and cause you to fall. Therefore, no one should ride scooters at night.

   3. Scooters are not toys! Children who are under eight should always be supervised when using scooters. Almost a third of all scooter-related injuries and accidents involve children under the age of eight. As everyone knows, scooters are capable of traveling very quickly, and children that age do not always have the judgment or coordination to handle these high speeds.

   4. Always ride your scooter Off-Road & Stay away from all cars and any other vehicles -Cars and scooters don’t mix, especially for younger riders. Smooth, paved surfaces are best – avoid bumpy, uneven, wet or rocky ones. Schoolyards, parks, paved trails are examples of safe places to “scoot”! Stay away from Sand, Gravel, Water and Dirt ¨C Try to keep your scooter on smooth surfaces.

   5. Always observe the basic rules of the road anywhere you use scooters. As scooters can travel as fast as many other types of vehicles, motorized and non-motorized, they too must observe the rules of the road. These include:

   -Stop at every stop sign. Look left, right, and left again before proceeding.
   -Stop at the end of the driveway. Look left, right, and left before entering the street.
   -Use proper hand signals.
   -Obey traffic signs and signals

   Not Recommended

   -Avoid jumping off of curves.
   -Too much weight on scooter can bend or break the frame.
   -DO NOT ride on a flat tire. This is dangerous and will damage the tire and possibly the wheel as well.

   Mechanical Tips

   Check all joints, hinges and quick releases to ensure the scooter is properly assembled. Stop using the product immediately if any joint, hinge, or quick release becomes loose. Correct the looseness prior to resuming the ride. Maintain proper air pressure in the tires. Low air pressure induces extra rolling friction, reduces ground clearance, and wears the tires quicker. If the brake lever touches the handlebar grip, stop use of the product until the lever is adjusted.

3. Fantastic blog! Do you have any recommendations for aspiring writers? I’m planning to start my own website soon but I’m a little lost on everything. Would you advise starting with a free platform like Wordpress or go for a paid option? There are so many choices out there that I’m totally confused .. Any tips? Thank you!

4. Nor would workers with just about all their Rhetorick, and Eloquent babbling demonstrate themselves fit for the Province of Heaven, or possibly individuals of great conscience on world.
