Grandson that I don't see often enough is starting to ask his parents for a 4 wheeler. I've ridden them very little, but I have a gut feeling that two wheels are safer. Am I off base? He will probably have very strict (paranoid parents - in my opinion) parental supervision, but they don't ride at all. I could/will take him out occasionally but they live four hours away. Any statistics out there regarding relative safety? Any other suggestions?
