A 3 wheel scooter can be a source of fun and entertainment for children and even some teens.  It can also be the reason some people are able to maintain their mobility even as advancing age or disease or even disability seems to rob them of their ability to travel.  In fact, a scooter can be the source of freedom to many people.

To begin with you should probably consider why it is you are looking for a 3 wheeled scooter to begin with.  As stated above the general divisions break down into two with fun being the first reason and regaining mobility for a person limited by health being the second.

Now you should look at the type of motor that is available if indeed there is one at all.  You have electric motors (most mobility scooters fall in this area), gas motors, and even scooters with no motors at all generally called kick scooters.  These are for kids and teens as people with some type of restricted movement will obviously not be able to kick start their 3 wheel scooters.

The maturity of your child will also determine which kind of motor powered scooter above you get for him or her.  Certainly you won't get a gas motorized scooter for a 5 year old.  You need to determine as well the maturity level of the teen when choosing between gas and electric.  

Electric will most likely by much easier to handle as you don't need to buy and maintain gas around your home.  However, a gas powered scooter will have much more power than an electric which might be needed if you are interested in terrain beyond the sidewalk.

Among the scooters for kids, you have to look at the weight limitations to be sure you get one that is able to handle the weight of your child.  There are some that will safely handle up to 200 pounds of weight.

Also, for young children, you may find yourself looking at the various character oriented 3 wheel scooters.  As characters are added and deleted it pays to check out what is available when you are ready to buy or more precisely, when your child is ready for you to buy.

Turning quickly to mobility scooters, you will find most come as electric powered.  You will need to insure you select one that will be able to provide you with the ability to travel for as long as you need before it must be recharged.  Most of these type are good for sidewalks and store shopping.  In fact, you can see this type of scooter in most big shopping stores these days.

Whatever type of 3 wheel scooter you are looking for your best bet at finding good prices and even sales is by looking online.  There are several websites that offer not only the product but also reviews of these scooters as well as additional information.
