Are their bicycle helmets that cover ur whole head?




Everybody


I just want to know if their is because i hate those crappy hats called helmets because they wont protect ur jaw etc, also is it legal in california to wear a motorcycle helmet while riding a bicycle. i want to b protected, if their are helmets that cover ur head for bicycles what r they called? i mean when i look at a normal helmet i say thats a stupid creation it should protect ur whole head.

Bike helmets are designed by the Industry to meet the specific demands of the sport. The modern bike helmets are designed to meet the high speed impact, and to be light and cool. A necessity in such an aerobic sport. Thus maximizing protection and comfort without hampering performance.

You can ride your bike with a motorcycle, full face helmet on .... it will exceed the safety requirements, but if you intend to try to ride with it beware of the weight and the lack of ventilation. The weight will make your neck sore and tired, and the heat will build up very quickly and can cause heat exhaustion.

In the BMX section of Bike shops they will probably have a full face helmet that may be more kindly for your needs. I can say that I have raced for several decades. Had many racing and street falls, broken / separated shoulder, wrist, and endo's shattering my helmet(s).... but never have I had an injury to my jaw.... in fact I have never seen an injury to the jaw.

Check out the BMX stuff but if they don;t have the ventilation, live with a good standard helmet!

Which Bicycle Helmet Should I Buy?




BillBill


I'll be doing all terrain riding. Was looking into Giro, Bell...are there any other reputable brands? And also there are many choices. My budget is no more than $80.00 Thanks!


Answer
All helmets must meet the standards set by the Consumer Products Safety Commission. Look for a sticker or label to that effect for every helmet that you consider.

Every time I buy a helmet I go to a well-stocked bike shop and try them all. I buy the one that feels the most comfortable regardless of the name on it. So far, Giro has been the winner most of the time. My unscientific experience is that Bell helmets tend to fit better for heads that are more round than oblong. Giro helmets tend to fit better for heads that are more oblong than round. But, that's just my opinion. YMMV.

What do you get for a more expensive helmet? More expensive helmets are supposed to be lighter, better ventilated, and have better retention systems. One thing for certain -- you do get bling and more expensive marketing!

Is full-face bike helmet ok??




nick


Bout to ride bike (standard bike ) to Walmart, and friend putting me in a full face bike helmet. Are these ok on bikes? Sticker says 'for non motor bikes only'. Didnt think they made full face helmets for reg bikes, are these ok style wise? Seems odd


Answer
They make full-face helmets for mountain bikes now (that is, bicycles). They're for riding through trees and stuff so you don't get slapped in the face with branches. They're very light, they're good up to about 15-20 mph.

Most states require a DOT (Dept. of Transportation) approved helmet. But the DOT's standards allow manufacturers to simply declare they fit the standard. There's no requirement for outside testing by an independent lab. Some of those little beanie helmets you see on Harley guys are not DOT approved, but they carry a DOT sticker in the packaging, which you can put on yourself, and that's legal!

Anyway, try on a full-face helmet made for a motorcycle and you'll see, it's a lot heavier and more substantial.

What should a simple bicycle helmet cost? I think some sports stores are way over-priced?




starryeyed


WEll, I'm on a budget, and I returned a helmet to Target for $15.00. Now, I thought maybe it was cheap, but then when I look at the $40.00 helmets at Sports Authority and Dick's Sporting Goods, I wonder if they're the same quality, just over-priced, or if I'm really getting somethign better?
Right price? Good store in Albany, NY or national chain?
Wow, there's a lot of helpful people and good info here already! THanks to all... will be back for a best answer later, but it will be tough.
The story about gettng one's head run over by a truck was especially moving!
Thanks!



Answer
More expensive doesn't mean safer. The main thing you're looking for is if it is certified to meet certain standards of safety. The pricier helmets usually cost more for reasons other than safety: design, lighter materials, more ventilation, more "advanced" or easier strapping systems, and their higher price has nothing to do with safety. Perhaps the "lightness" feature (the helmet being lighter in weight) may be important enough for you to pay more, but I don't know that any helmets are "heavy." The important thing is to look for is a helmet that meets safety standards and that has a good fit for your head (so try it on before you buy and compare the fit of different models).

What to do when your bike path forces you to use the crosswalk?

There is a "bike path" but have to cross a lot of intersections.

Cars are allowed to right-turn on red.

Forced to use the crosswalk unless I do something like jump the curb into the street to be on the other side of the "right turners" which is not always possible or safe.

Or annoy people by shining my helmet light in their eyes...

Presence of a bike path means I can't be in the road and I wouldnt want to.

(because nobody else does around here, and roads such as this especially)

If I sat at the light long enough for it to be clear, I would never cross. Not like I am racing to get home but just want to get crossing over with.

I suppose crossing at a different time of day would be possible.

And yet it is the closest thing around here to infrastructure...

Ride totally in the road? Nobody else does. I do on certain roads.



Answer
Your quote, "Presence of a bike path means I can't be in the road and I wouldn't want to."

Your bike path or a designated "bicycle lane"? If you don't learn how to ride properly on the streets - as a "vehicle" should - you'll be a scared little chicken all your life. Yes, a bicycle is designated as a "vehicle" and is legally allowed on streets & roads everywhere - except Interstate Highways & other "limited access roads". Not the answer you want to hear, but the truth. Got a Cycling Savvy class in your area? Take ALL the classes. More links below...

"Ride totally in the road?" YES! It's the LAW. In most places, it's ILLEGAL to ride on sidewalks.

When choosing materials to make helmets, what physical properties would you look for?




Mariella M


You work for a company that makes helmets: motorcycle helmets, bicycle helmets, baseball and football helmets. When choosing materials to make these helmets, what physical properties would you look for? explain


Answer
Durability: the material may be impacted by another object with greater
hardness, but sustain little or no permanent damage to its own structure.
Hardness: the material needs to have a hardness that is as great as
possible so that it will be protective to the wearer when impacted.
Resiliance: the material needs to be able to absorb an impact with
some degree of deformation, but return to its original shape when the
impact force has been removed. This absorbtion of energy is critical,
because one does not want the impact force to be transferred to the
wearer. The idea is to sacrifice damage to the helmet material, and have
it absorb the energy of impact, rather than have that energy passed on
to the wearers head.
Light weight: the material should be as light as possible for comfort to the wearer.
Easily shaped: the materials need to be easily formed by standard manufacturing methods, so that it may be built efficiently and for the
lowest price. Efficient methods include processes like hot-melt molding,
blow-forming, and machining.
Low cost: the basic materials need to be as low cost as possible to make
the finished product affordable and competitive with similar products on
the market.
