Most states require a person to be at least 12 years old before they can ride a pocket bike. If you let someone younger ride a pocket bike remember that you are responsible for their safety. Always monitor their riding and, if possible, let them ride in a closed off area with a soft surface, such as grass or dirt.
Safety is not the only thing you need to think about when having fun with your pocket bike.
When driving your pocket bike you need to make sure that you not only follow certain safety rules – but also the law.

A pocket bike is a quick and maneuverable vehicle, so you should expect falls and scrapes and prepare accordingly. If you fall onto a hard surface or an edge you will take much less damage if you are wearing the proper safety equipment. Make sure your helmet is approved by the appropriate licensing body in your country. Wear a riding suit, gloves, kneepads and a pair of riding boots. Apart from your skull, your legs are most exposed to injury.
Get used to how your bike sounds and handles and pay attention to if something changes. If it does it can be a sign of a imminent malfunction.
