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.
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.
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." :)

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*
