The law also states that anyone under 16 who wants to operate a motorized mini bike must be supervised by an adult. Therefore, even if an 11-year-old is experienced in riding a pocket bike, they would still need to be supervised by an adult in Massachusetts.
In addition to the potential for crashes and injuries, riding a motorized mini bike can also be harmful to the environment. These bikes emit harmful pollutants, and they can also be noisy.
For these reasons, it is not safe or legal for an 11-year-old to ride a gas-powered pocket bike in Massachusetts.
