An all-terrain vehicle (ATV), also known as a quad, quad bike, three wheeler, or four wheeler. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street legal within the United States. In 1988, the All-terrain Vehicle Safety Institute (ASI) was formed to provide training and education for ATV riders.The cost of attending the training is minimal and is free for purchasers of new machines that fall within the correct age/size guidelines. Successful completion of a safety training class is, in many states, a minimum requirement for minor-age children to be granted permission to ride on state land. Some states have had to implement their own safety training programs, as the ASI program cannot include those riders with ATVs outside of the age/size guidelines, which may still fall within the states laws. Current Chinese brands are Coolster, BMS, IceBear, CFMoto, Hisun, JCL, Tao Tao, Kazuma, and more! These atvs runs in Motor size from 110cc 125cc 150cc and 250cc to 800cc.
