As for accidentally dropping helmets on the floor, it seems to me that styrofoam is not glass. Sure it's like glass -- fiberglass. I believe that's what the outer layer is. If you go down (or drop it) once, it might look fine but be cracked. The next time (and hopefully there isn't a next time) it might not hold together when it is whacked. Impacts could cause a number of things to go wrong. It could cause a crack that cause the helmet to split in half on the second impact. It could also compress the foam (which isn't elastic) and the second time you don't have the same level of protection becaus the foam is compromised. You could also have a situation that there is a crack near the chin/ear and if you impact something it could break off a chunk and the chin strap would have nothing to hold onto and the helmet could come off. For some bikes, like mine, you're talking a 850lb bike with the engine the same size as a small car. Lots of things can go wrong just because of the size, weight, speed and the fact that you are out in the car lanes. On a motorcycle, helmets play a variety of roles that they don't on a bike. First off, they protect the eyes if you wear a screen. That's real important. Second off, it protects the head from debris: rocks, rain, bugs, etc. It also cuts down of noise and wind, so it isn't as tiring. For some rides, it also holds the communication equipment: stereo speakers, CB/radio speakers, intercom, and microphone. Finally, if you're riding with 2 people -- esp. a kid on the back -- you have to take into account that motorcyles can stop and accelerate faster than anything else on the road. Because of that, it's not uncommon to have the rider's head hit the driver in the back when breaking. It's not too hard, but it's noticable (when I get clunked right on the spine between the shoulders). I helmet helps protect the passenger in the instance. Someone mentioned gloves. I wear gloves but not really for the protection. It is more for the grip. Holding the throttle for an hour or so can hurt your hand. So with a good glove, it makes it so you don't have to squeeze so hard to grip it. Plus helmets, gloves, leathers, etc. all play a role now it is getting cooler and you have to take windchill into account. On bicycles, I am sure there are benefits to a helmet but the benefits are nowhere near the same as the benefits on a motorcycle. Just getting hit with a June Bug or rock or grasshopper at 70 mph is a whole different thing than getting his at 30 mph. I think bike helmets are designed lighter so that they control the crash of you hitting the ground or maybe a slow moving car. They can absorb that and help you. But they are not design for a 30mph bike hitting a 45 mph car head-on. As for me, I can understand people not wanting to wear a helmet on a bicycle. I generally don't when I ride one. But I do on a motorcycle. I was in PA just a few weeks ago and road for about 20 min without one, just to say I did. But I was uncomfortable and found I actually prefer a helmet for no other reason than to keep the wind off my eyes. To answer the question someone is bound to ask. My helmet is about 3.5 years old and I don't intend of replacing it soon -- but it's out of the sun all winter so there's no UV exposure. If I dropped in concrete from shoulder level, yes, I probably would replace it. For my kids' helmets, I would definately replace it. Here's a weird final thought for you. There are, I believe, 3 classes of mopeds in NY. I think the Class C can go up to 15 MPH. So basically, it could be outrun by a bicycle. However, the moped requires a motorcycle helmet but someone over 14 on a bike isn't required (by state law) to wear anything. Go figure. |

Have you ever been run over by a train and cut in two without head injuries and the top half jumped up and said "I'm fine."? I saw the results of human versus car and human versus Semi and helmet or not, all the pieces scattered around were DEAD. My wife and her 2 children by a first husband (wife beater) saw a drunk try to hop a train and he missed the handrail. He went right under the wheels on the bridge and there were people trying to picnic down there with human body parts falling on them. The major part of his liver fell in the exact middle of their cloth. His head, unhurt, was about 50 feet away, without a helmet. The fire department was called not to render aid and sew him back together, but to pick up all the pieces and hose off both the tracks and the beach. Since this happened before I met my wife in 1977 all I can say is that it happened sometime in the 1970's in Santa Cruz, Ca. Do yah think a brain bucket would have saved him? Maybe they wrote it up as pedestrian killed, no helmet. For you, a big "Duh!". Bill Baka |

I've dropped a lot of styrofoam in my time, and have never had it shatter or be damaged such that it can't survive a second dropping.

Impacts could cause a number of things to go wrong. You can say that again. But it seems to me a helmet should be able to survive a little rough[ish] handling.

I wear a skate rated pot with a hard shell. They're supposedly able to take multiple impacts from one meter. That's about how far I drop it at least once a week. Sk8 lids provide some protection to the occipital (perhaps the most vulnerable) region of the skull. Typical bike helmets are designed as if yer gonna land on yer crown in a fall. About the only way a rider is going to hit anything with his/her crown is in a head-on collision with a motor vehicle where the rider gets torpedo-launched into the windshield, or flung over & behind the motor vehicle, landing head-first onto the road. And while helmets aren't ostensibly intended for that, that's the skull protection their design implies (or downright lies about.) Actually, I'm particularly appreciating my own bucket right now, now that horse chestnuts are falling out of the boulevard trees. I once tested it by walking, head-down, into a brick wall. Better replace it ;-) IIRC it had something to do with demonstrating a point during a headgear discussion. Wearing the required hard-hat at work, I'd sometimes deliberately walk into a stud or door frame just to comment how glad I was to have been wearing that plastic hat. Wear 'em backwards in the rain, and they gutter the rain behind your back like a fireman's hat. More or less. Until you look down to roll a smoke. cheers, Tom -- -- Nothing is safe from me.
