starting @12:36 ...and break a boner too!
I did mention Mike Tyson in the video, but I don't remember talking about my magic johnson...
OK, OK, I'll see myself out.
:)
@@BikeGremlinUS hehe I guess that your IQ is about 150. Am I correct?
Well, if we're calling it IQ - it's way less than 150 mm. LOL :)
@@BikeGremlinUS STOP THAT! :)
@@BikeGremlinUS They removed my post about IQ. What a world now.
Oversafety feeling goes for body armour as well, people think they are invinsible, but your decision making regarding risk is your best protection
If you think a bicycle or hard hat can be uncomfortable: About 2 years ago, I fell from a tall ladder at home, while painting my 2-story home, alone. No helmet. Fell and broke ribs, which punctured a lung, broke shoulder blade, skull fractures and brain bleeding, as well as a medium level Traumatic Brain Injury (TBI) - as many car accident victims get. Life was saved, no surgeries required, put in a coma for better brain health for first week, in ER, Intensive Care, then rehab. hospital, for 6+ weeks. Then 6 more weeks in Outpatient Hospital Therapies. Happy to be alive. Left only w/ slight double vision, correctable with glasses, mild balance issues, and occasionally can't think of the right word. I "had" to ride a bicycle for transportation, until I was able to be approved for renewing driving 6 months after accident (6 months seizure free). Had to retake my drivers test. I'm usually the safest person I know. I don't know why I fell from the ladder, as the TBI put me out and I had almost no memories made in first 6 weeks. (Weeks #2-4 I'd keep waking up, not know what happened, or why I was in a hospital, but I felt great so didn't think anything was wrong, that I should go home.) In Rehab. Hospital, they quickly got me eating, standing, balancing, walking, and then started the repetitious tests to try to detect any mental problems - none found. But they gave me the same tests day after day - puzzles, word problems, Math, and occupational therapy (cooking, laundry, daily personal hygiene). I couldn't shower alone for first 2 weeks in Rehab. I hated the clothing alarms, bed alarms, had to stay in my room, then only on the same hospital floor, and restriction forbidding hot coffee initially. I wish everyone would wear a helmet. Helmets are NOT optional - neither are brains. My family, some from out of state, came to my side so somebody I recognized was there every day for 6+ weeks! My neighbors mowed my lawn. One of my sister's got me a cell phone and paid for my Uber rides. My other sister came every weekend, took me to the store and helped me fill out the Financial Help forms for the medical bills that insurance didn't cover. I'm no longer "allowed" on tall ladders. I wear a bicycle helmet when I get on a short ladder, or on a bicycle, because I value life, and my independence. I like living at my own home and know, like everyone, today could be my last day, so I'm writing my Will this week. On my bike, I have and use a mirror, a flashing, rear one all the time, and a headlight at night.
Great video, and a lot of interesting explanations, thanks
There have been studies that concluded wearing helmet gives false sense of security. So you'll attempt that jump that otherwise doesn't make sense to take. Understanding the details lets people make informed decisions not only in what helmet to purchase but a way to be a better, safer rider. Great video!!!
Please give a reference to these studies. Thanks
@@fintonmainz7845 in regards to American football, not necessarily cycling... but anyways... maybe Google next time... but for the lazy
Copy/paste
Dr. Eric Swartz of the University of New Hampshire conducted a study that showed helmetless-tackling drills reduced head impacts by 28%, as players without helmets were less likely to use their heads for tackling, illustrating the false sense of security provided by helmets [❞]. Similarly, other studies have suggested that football helmets can create a sense of invincibility, leading players to use their heads more aggressively [❞] [❞].
@@fintonmainz7845 also when am saying false sense of security, I mean beyond the safety the helmet can provide... like the video is talking about. Am not suggesting not to wear one. Just to be clear.
@@AlenAbdula Si nothing about cycling. Thanks for the info nevertheless.
@@fintonmainz7845 the psychology still applies. But go ahead continue to be ignorant.
I did fall last year because I was mucking about on the bike, fell on my side and hit my head on the pavement. I didn't wear a helmet and in that case it would have helped cause I hit the asphalt on the top of my head almost. Hopefully I didn't sustain any damage long term but you never know. It hurt but I didn't feel nauseous or anything, I got a big bump on my head though (gone now of course). I still don't wear a helmet when I ride but I try to do less stupid things on the bike.
In Sydney Australia it’s a on the spot $344 fine for not wearing a helmet.I’m wearing mine thank you very much.
AFAIK the forced helmet law has resulted in a reduced number of cyclists in Australia. :(
You live in a tyranny.
Double D isnt really needed for lid typee cycling helmets, its the full face design that wants to be pulled of when sliding
Do you need a bike helmet? If you wish to participate in any sort of organized ride, yes. Yes you do. They won't let you take part without one.
In my country it is often not required. Encouraged yes, but not always required.

The scums demanded full shots to ride with the group. F 'em all.
In essence you want the lowest deceleration possible. In terms of Mechanical Engineering you want energy to be absorbed by plastic deformation and as you stated , preferably at low pressure to deform as much material as possible. Most of my cycling accidents have been caused by other road vehicles colliding with me so being careful doesn't always work 😞 The last one was a bus and most of the impact energy was absorbed by the drivers laminated window glass shattering and deformation of my bike ! Also cyclists have a fair chance of being hit from behind. I had a wing mirror of a van hit me at about 80kmh when I was out of the saddle on a climb. Luckily it hit my shoulder and not my head. I don't know if this is taken into account in the design of the rear ends of cycling helmets ?
I have made articles and videos about cycling in traffic. There is a lot one can do to be noticeable (not the same as being visible). Sometimes you can't, but very often you can do things to avoid an accident or to at least make the impact be less severe. Some people call that "victim blaming" nowadays, I just call it: "I'm trying to stay alive." :)

Gen X wore no helmets.... they didn't exist... we fell.... most of us are still here.... Sure enough when we did dumb shit we tried to be more careful... that's very unlike compared to today...
What about downhill helmets ?
High-quality downhill helmets are a lot closer to motorcycling helmets than they are to what's generally sold and called a "cycling helmet" (the white helmet in the video). They offer a lot more serious protection.
Relja
@@BikeGremlinUS I always prefer those helmets even for cycling than cycling helmets ... about the "stroke" from heat, i don't think that applies to everyone or maybe every downhill helmet ?
They are more enclosed and hotter. Whether that's tollerable depends on the temperature, how hard you pedal, and your body (in the summer, I sweat by just sitting :) ).
@@BikeGremlinUS thank you very much (◠‿◠) very informative!!

60 years old and still riding. I have never in my life, have worn those dorky looking helmets. I just choose not to. I've crashed and fell off my bicycle numerous times through the years. Never once, have I hit my head.
It should be a choice for everyone to make for and by themselves. A guy from my high school fell and hit his head on a basketball court, with no obstacles and no one near him.
On a 5 a side football match, on an asphalt court, a friend managed to fall on his back, hit his head, and went into shaking, so we had to turn him on his side and take his tongue out.
I had a 40 km/h motorcyle crash, in a turn (low side, some fine sand over the asphalt) with that red helmet on, and as you can see in the video, the helmet has no scratches (I just tucked and rolled, instinctivelly, thanks to judo training as a child).
A friend who is a very good cyclist likes riding aggressivelly off-road, and during a crash he had a pedal dig into his helmet. On another occassion, he had a sharp rock dug into his helmet after a fall. Would not have been fatal, most probably, but would have ruined the day (never does extreme stuff all on his own, just in case someone needs to call an ambulance).
So, I dare not tell anyone whether they should or should not wear a helmet. It depends. But it should be a free choice and not obligatory by law - at least in my opinion.

@@BikeGremlinUS Totally agree with you. "It should be a free choice and not obligatory by law"
More luck than good judgement! You probably did and can't remember due to brain injury lol.
@@SportCampTirol Nope. I even drink from a garden hose. *gasp*
