By now, you’ve probably noticed the ubiquity of the bike helmet.
It’s ubiquitous, as evidenced by the fact that every single one of the millions of helmets you can buy on the market today is designed to fit.
Even the ones designed to protect against head injuries (like the ones you can purchase on Amazon) are designed to reduce the amount of force a bike rider can absorb.
But what about the ones that protect against your brain?
Bicyclists are no stranger to helmet use, as we know from the studies above.
A 2013 study found that a bike helmet reduces the risk of concussion by around 5 percent in the first year after wearing it.
The same study found a similar reduction in the risk in the second year after a helmet was worn, and another in the third year after that.
And the helmet’s protective effect on the brain is not limited to the head.
According to a 2015 study, wearing a helmet reduced the risk for Alzheimer’s disease by 10 percent in adults and 11 percent in children.
And it was even shown that wearing a bicycle helmet reduced a person’s risk for developing dementia.
So why would people buy helmets to protect their brains?
A helmet’s primary purpose is to protect the wearer from the damage of hitting a car or pedestrian.
But, if you’ve ever looked at a bike that is still running, you’ll know that the helmet can be a little tricky to get on and off.
The helmet’s visor, for example, is often hard to get onto, which can cause the helmet to look like it’s on the back of a bicycle rather than on the front of the rider.
That’s because the visor is not completely transparent, and a bike with a lot of visibility is likely to have a lot more visible light reflecting off the helmet than one with a few inches of visibility.
The visor’s surface area is also quite small, making it difficult to fit a helmet in there without damaging the surface of the helmet.
The only way to get a helmet on is to mount it on your head, and even then, it’s often a bit tricky to do so.
This means that a lot people end up wearing helmets with a hard, rounded-top design, and these are often not the most effective helmets.
The best helmets, however, are the ones with a curved design.
These helmets are designed with the helmet in place, but the visors are not fully visible, which means that the visoric material can be pushed up against the visocutors in the helmet and get a little bit of an image.
This creates a little extra area for the visored material to shine through.
This design has been proven to reduce concussion risk by around 8 percent.
While you can often find the best helmets in the best manufacturers, there are many companies that make helmets that are less expensive and more comfortable.
The ones that make the most money are the brands with the best ratings from the helmet industry, which include AVID, Bontrager, Brooks, Dura Ace, Fenix, Felt, Geppert, Giro, Griptonite, GSI, GTS, Kenda, Lidl, Neoprene, Orthos, Pro-Guard, and Tresor.
These are all top-of-the-line brands, but they don’t have to be.
A good helmet can also be customized to your needs.
The more you buy, the more you can customize your helmet to suit your own body.
Some manufacturers offer a wide variety of different visors to suit different people.
For example, Durex offers helmets that fit children and adults in various different sizes, while the brands below have more specific helmets that can fit different types of riders.
If you do decide to buy a helmet, you should make sure that the price is right for you.
A helmet that is too expensive can cost you a lot, while one that is not expensive but does not suit you will probably be more comfortable for longer.
