That's the first thing I thought when I read the opening post. Looking cool by having the straps hanging down the side of your head is not smart. You should have the helmet properly secured to your head when riding, don't rely on gravity to hold the helmet in place.
Another thing: watch the gas tank because someone might try to put soda or some other material into it. I suggest buying a locking gas cap.
