INNER MONGOLIA — Our society is increasingly interested in convertible and modular products.

For example, if you're a new parent shopping for baby items, you'll notice nearly everything fits these descriptions. The crib you're looking at converts into a toddler bed. The car seat is convertible and can become a barbecue grill. The stroller is modular and can be combined with a pack-n-play to become a massive, mobile play structure.

But you typically don't see these features with ATVs. That's why I was intrigued by this video.

It's important to note this rider was not injured. He's lucky, too, because he wasn't wearing a helmet at the time of this crash. Fortunately, he wasn't going too fast when one of the wheels decided to roll free.

So, consider this your PSA for wearing a helmet. You never know when your four-wheeler is going to become a three-wheeler, your three-wheeler is going to become a two-wheeler, or your dirt bike is going to become a one-wheeler. Wear a helmet and stay safe out there.
