Few topics in cycling inspire as much controversy as helmets. Some people insist they’re essential, calling non-wearers reckless and invoking harsh and violent imagery: “enjoy your traumatic brain injury”. “You’ll regret it when you’re in a hospital with a feeding tube”. You hear suggestions of denying access to public healthcare. On the opposite end, helmet skeptics argue that they’re a distraction. I’ve actually heard people call them “magic hats” that “don’t offer significant protection (if any at all)”. Helmets dehumanize cyclists and send the wrong message. They’re dorky and uncool, rather than fashionable and European.

So what’s the truth about helmets?

    Bikes mixed with faster metal objects? Wear a bucket and pray to god.

    Bikes separated from cars and people on specific thoroughfares? Doff the lid and ride easy.

    It’s not the bikes’ fault, but that’s not really relevant – they squish the same either way when up against a car, at fault or no. The only true prevention is separation so the cars can’t get close.

    I have seen far enough people died who could have survived if they wore a helmet. I rather keep wearing one. The same thing when in any two wheeled vehicle.

    Here’s the thing…yes, wearing a helmet is less safe than having bike infrastructure. No doubt about it.

    But I don’t fucking HAVE safe bike infrastructure. Also, I am very involved in bike safety advocacy, so I’m not exactly just shirking all safety responsibility onto a silly hat and expecting things to be fine.

    We can throw off the dualistic thinking for a second and acknowledge that, yes, helmets are a very imperfect solution that puts the onus of protection onto riders. Also, it’ll save your goddamn life.

    If I didn’t wear a helmet, I never would have gotten married and my kiddo would never have been born. I’d have died on a sidewalk (or in an ambulance) on the side of a residential street on a multi-use path where a dumbass teenager was going 35mph the wrong way on an electric scooter at night.

    Even if you exclude injuries from automobiles, head injuries are far and away the most common serious injuries people get while cycling. This entire debate is idiotic. Wearing a helmet is such an easy thing to do and has basically zero downsides.

    This shouldn’t even be a question.

    Two bicycle accidents here, both involving cars who couldn’t be bothered to look around them when circulating. In both cases the helmet saved my life.

    When I see hipsters on their brake less fixie with no helmets to make sure their hair don’t get messed up, it makes me shiver. It’s such a simple thing to do that brings a maximum of protection.

      It depends on your city.

      In the Netherlands you’d probably be laughed at for wearing a helmet.

      The bicycle infrastructure makes it so safe here, kids cycle alone to school across busy roads from the age of like 7

      I recommend watching the YT channel Not-Just-Bikes it’s fascinating and I wish more counties were built like the Netherlands

    Had a workmate that said helmets are ‘just for kids’, he was riding his bike home from work one evening and slipped on some sand on the path while rounding a corner that he’d ridden hundreds of times prior. No cars involved, nothing but him his bike and a pavement. His head hit the cement path, and he was dead before an ambulance arrived.

    No helmet.

    His funeral was the largest I’ve ever attended (200+) and his teen son reading a eulogy was something I’ll never forget.

    I miss him. He was a great guy, intelligent and funny and always had interesting stories, enjoyed discussing conspiracies - but more the ones with evidence (COINTELPRO etc) over pure speculation. The one dumb thing I thought he did regularly was ride daily without a helmet.

    So yeah, you guys who think helmets make no difference - you’re wrong. The impact forces delivered to your skull is enormously reduced by wearing a helmet, and everyone that chooses not to wear one is convinced, “that won’t be me, I ride safe, I know the path well”. You’re wrong, and you’re gambling with your life - for what?

      And I have had my life saved in almost the exact same situation by a helmet. This conversation is stupid. Head injuries are still the most common serious injury involving a sole cyclist - that’s without cars, pedestrians, dogs or anything. Literally thousands of people every year hit their head just falling off bikes.

      A friend of mine was in a bike crash during an event (large group ride, not a race), and he firmly believes the helmet saved his life. Even with it, he had a concussion that kept him off the bike for months. (I wasn’t there and don’t recall any details of the crash, if I heard any.)

      That said, nothing is perfect. Another friend of mine slid on some leaves, crashed, and died several days later in the hospital. He always wore a helmet, too.

      I always wear mine when riding.

      Had a doctor who also rode share a story with me. He and a friend had finished a ride and were in the car park, friend took off helmet as the chatted and cooled down, friend then remounted and began riding to his car, slipped on debris at 5 mph, fell, stuck his head, dead before the ambulance arrived.

    Most stupid discussion ever. I remember a couple of years ago when there where motorcycle riders protesting a new helmet law ( I think it was NYC). Dude won the Darwin awards smashing his head and it was concluded that he probably had lived if he had a helmet.

      Have a cousin who is a nurse, she mentioned seeing an anti-helmet protest on the news, amongst the protesters were some of here dialysis patients. I guess one way to speed up the transplant queue.

    Ever since I learned in motorcycle training that having your head go into a immovable surface (curb, tree, etc) at just 10mph can easily kill you, I wear one while skiing and bicycling. Just like seatbelts in a car, I don’t feel safe enough anymore without wearing one. I’ve always worn ‘heavy’ helmets for the motorcycles anyway, so the lighter ones for bikes and skiing are barely noticeable.

      Yeah, the truth is, there are a lot of opinions out there but the vast majority of people are absolutely clueless about how vulnerable human brains are. We have to learn everything the hard way.

      If you can wear shoes, you can wear a helmet. It’s not that hard.

    For me, the truth is I barely notice I’m wearing a helmet, and cars barely notice me as a cyclist even exists.

    So even if a helmet only does half of what it claims to do, I’ll take that chance in an accident with a giant metal box on the road.

    Studies in USA show automobile drivers perceive helmet less bicycle riders to be more dangerous so they give them more space. Therefore it is safer to not wear a helmet, up until the point your head makes contact with something. That said I always wear a helmet. Been hit by cars twice, twice cracked my “styrofoam hat” but not my skull.

    I wear a helmet. Either I’m mountain biking, or I’m in a bike lane along cars, where I’m riding in the 22-25mph range and the cars are in the 45-50mph range. If I get directly run into, it probably won’t make a lot of difference, but if I get clipped/knocked down, way more likely, it quite likely will.

    I don’t think they should be mandatory, but it does bring up the same arguments that get made about motorcycles - if you don’t wear one and you crash, will the (horrible, shitty, awful, stupid, American) insurance industry try to reduce their liability? Rhetorical question, of course they will.

    Biking is safe whether or not you wear a helmet. The life-extending advantages of biking outpace the life-shortening risks either way. If wearing a helmet makes you more comfortable and you bike more, then that makes a bigger difference than the helmet itself.

      Conclusions

      On average, the estimated health benefits of cycling were substantially larger than the risks relative to car driving for individuals shifting their mode of transport.

      https://pmc.ncbi.nlm.nih.gov/articles/PMC2920084/

      Even without a helmet, cycling is a safe, beneficial activity. Helmets offer significant protection if you fall off your bike or crash it (though much less if a car hits you) but the absolute rates of injury are small enough that this is a personal judgement call.

    @lgsp I’m a fan of requiring them over 25kmph. Yes this is largely unenforcable, so no one will be fined. But it still gives the message that if you go fast you should wear one.

    But it also gets out of the way of people riding to the corner store for milk
