How Do Four Wheelers Work?by Isaiah David
Four Wheeler Definition
Four wheelers, also known as all-terrain vehicles (ATVs) or quads, are small vehicles designed for one or two people. They have handlebars like motorcycles, low-pressure tires and a seat exposed to the elements without the enclosed cab that most cars have. They are capable of going off-road and can negotiate fairly narrow trails and other places cars cannot because of their size.
Four Wheeler Design
Four wheelers are specialized for riding off-road and on steep trails. Their low-pressure tires absorb bumps and jolts well without popping. The tires are knobby, which gives them the traction needed to dig through loose dirt and gravel. With a "soft" suspension system, four wheelers are able to navigate the uneven terrain of off-road and trail driving. Finally, four wheelers have very powerful engines for their size, allowing them to climb steep hills.
Utility and Sport
Four wheelers come in two basic styles: utility and sport. Utility four wheelers are bigger, heavier and more practical. They have racks built in as well as hitches, and body panels to protect the rider from spray. They are good for towing trailers, transporting gear or doing farm work. Sport quads are smaller, lighter and faster. They have looser suspensions to deal with high-speed riding and jumping, and very quick, responsive turning. They are a bit harder to control, and can't do the heavy moving that utility quads can, but they are better for high-speed recreational riding.
