How To Choose a Bike Helmet

Here are key key things you should keep in mind when in the market for a mountain bike helmet.

Types of helmet

The key difference between MTB and road helmets is that the former generally provides a higher level of protection and is less aerodynamic. However within MTB helmets there are a range of types that provide different levels of protection to suit different styles of riding.

Half shell/open – Similar in shape to road helmets, these provide good ventilation and are generally lightweight, however offer limited protection around the lower parts of the head.

Open Face Enduro ¾ – Probably the most common variety of MTB helmet – similar in look to the half shell but providing extra protection around the side and back of the head.

Full face Enduro/Downhill – suitable for more aggressive styles of riding, the full face helmet provides the highest level of protection. Covering a large amount of the head, as well as a chin guard to protect the face.

Convertible full face – The best of both worlds, a convertible helmet offers full face protection when needed, with the option to convert to ¾ during less aggressive riding or when ventilation is required.


There are a couple of things that you’ll want to do as a minimum, to ensure your helmet will provide an acceptable level of protection for you on the trails.

  • First, you want to ensure the shape and size of your helmet means it fits on your head correctly.
  • Secondly, check it meets the Australia and New Zealand AS/NZS 2063:2008 Safety Standard.

Following that, you can look into more advanced protection features such as MIPS, a fairly new technology designed to reduce rotational forces that can result from certain impacts.


The size and shape of your helmet will be the key factors contributing to comfort, so make sure you do your research, and if possible try one on before you buy.

Different helmets do come with different levels of padding and strap configurations which can also influence comfort.


If you will be riding in warm conditions, ventilation can be a very important factor when shopping for a helmet.

Worth mentioning is that if you are generally a cold weather rider, a helmet with big air vents is going to be chilly, meaning a helmet with fewer vents may be more suitable.


The lightweight construction of modern helmets means that weight is generally not a huge concern for most riders.

Obviously, if you opt for a full-face helmet you will be carrying significantly more weight on your head, which is worth keeping in mind if you’re deciding between different styles.
