    Ride Safe and Have Fun!
    Off-road riding is great fun! When you take proper safety precautions, injury is less likely to occur. As a responsible rider, you must outfit yourself in appropriate safety gear every time you hit the trails. Doing so keeps injuries and equipment damage to a minimum.

    Buy a helmet safety approved by the Department of Transportation. It will have "D.O.T." stamped on the back, near the base. It should fit snugly, allowing very little head movement within the helmet.

    Purchase a quality set of goggles. Trail debris can hit a rider in the face, and sunglasses do not offer enough eye protection. Purchase special safety goggles that easily fit over prescription eyeglasses if necessary.

    Obtain a high-quality pair of off-road riding boots. Tennis shoes and hiking boots are not safe enough for off-road trail riding. A single rock can break an ankle on an ORV trail. Stout riding boots with heavy-duty casings are essential trail safety gear.

    Buy a comfortable pair of riding gloves. Vibration from the handlebars can cause sore hands and wrists. A good pair of riding gloves will absorb some of the impact and make your ride more enjoyable.

    Purchase the appropriate clothing. Regardless of outside temperature, wear a lightweight, long sleeved shirt and thick, full-length pants to protect the skin. Breathable material is necessary, as are bright colors easily visible to oncoming riders. Riding pants and jerseys offer the rider much needed protection from overhanging limbs, branches, and flying debris.

    Acquire a chest protector. Stones thrown by other ATVs and unexpected branches in the trail can hit a person squarely in the chest while trail riding. It is extremely dangerous to have the wind knocked out of you at 50 mph. A chest protector is mandatory safety gear for ORV trail riding.

    Purchase a good neck brace. It provide strong support and good protection to your neck and it is mandatory to wear for dirt riding in some states.

Review October 18, 2016
Reviewer: Tom Dunham from Gaylord, Michigan  
The Coolster 50cc is a nice bike for a smaller kid.  My son loves it and will upgrade in a couple years.  Surprised how fast it arrived.  The customer service was good with this company with letting me know what was going on with my order which was real nice.  I was a little bit iffy ordering from a smaller company but now I am glad I did.
