There is no age restriction
Have not seen any laws against children riding on the back of a motorcycle, but do use some sense. Is the child capable of knowing to hold on and not let go? Do you have the proper gear to put on the child?
There are a number of riding toys that can be purchased for children of varying ages. Fisher Price makes riding toys suitable for very young children. Small two-wheel bicycles with training wheels can be purchased for children aged four and up and generally children from age five can have the training wheels removed.
No minimum age, BUT, you need to install footpegs that they can reach comfortably.
All children love to ride toys. Form the time they can walk, children are looking for something to sit on and push with their feet. A tricycle is one of the first riding toys that parents can get their child. Tricycles are made of plastic for small children and metal for older ones who have a better grasp of walking. Other riding toys include horses, motorcycles and small animals. There are riding toys that also have batteries that resemble larger vehicles like jeeps and cars.
the child must have a full body suit and an current helmet with padding, including knee pads,elbow pads,ankle guards,and gloves.
There is no age requirement. As long as they can reach the pegs and must wear a helmet.
It depends on where you live, but in the US, in most states that I know of, once you have a motorcycle license, you can buy and ride any motorcycle you want. You have to look into the state laws for where you live. I would recommend starting off on a small dirt bike and building skills before riding on the street in traffic with the crazies.
Kansas does have valleys, albeit relatively small ones.
If you're asking if a helmet is required by law, it depends on the laws in your state. For example, motorcycle helmets are not required at all in Texas. If you're asking whether you should wear a helmet for safety, the answer is a resounding yes. On all vehicles where your body is exposed, including bicycles, you need a helmet. I had a friend killed riding a small motorcycle -- he went down and his hit head on a curb.
A quad or a mini motercycle
With the exception of the potential acceleration forces, and the fact that you don't have to pedal, riding a motorcycle is very similar to riding a bicycle. However, due to the speed achievable on motorcycles, and the fact that motorcycles are often ridden in traffic, motorcycles can be much more dangerous. Most states require that anyone applying for a motorcycle license take an approved course and/or pass a riding test, and required or not, this is an excellent idea. You would have to take another driving course to learn how and to get the correct license. yes you can ride a motercycle at the age of 14
