Best Bike Helmets For 2017 – Top Selections For MTB, Road Bike & BMX Bikes

Regardless of what kind of cycling you do, you should wear a helmet. In some countries, it is a legal requirement to wear a helmet while you are on a bicycle, but even if it is not the law, a helmet can save you from serious life changing injury or death in the event of an accident.

Although some studies have found that car drivers leave more space when passing cyclists not wearing a helmet, it is better to be wearing one just in case. If you are going mountain biking, there is no excuse not to wear a helmet. If you crash while riding off road, there are many objects on the trail that could cause you a serious head injury, such as rocks, roots, trees or even other riders.Best Bike Helmets

There is a huge number of helmets on the market and in the last few years, there have been some fantastic advances in technology, allowing lighter and better-ventilated helmets with very impressive protection to become available.

It is recommended to replace a helmet after three years of use, or after a crash that involved an impact to your head. Not sure if a crash was enough to damage your helmet? If there is any visible damage to a helmet, such as holes or cracks, then you must replace it. However, it is not always possible to see the damage as the foam inside a helmet is designed to absorb the impact internally.

For this reason, if you crash and feel an impact to your head that made you grateful to be wearing your helmet, then you should replace it. It is always better to stay on the side of caution because a helmet will not protect you if you crash again. The exception to this is certain BMX helmets that have been designed to cope with multiple low-speed impacts.

Kali Protectives recently gave away free helmets at bike events in return for damaged helmets. They were shocked by how many people were riding around on helmets that had obviously been involved in multiple crashes and simply were not safe to be using anymore.

Whether you are looking to buy your first cycling helmet or it is time to replace one, we have rounded up a selection of the best helmets available. You will find suggestions for road cycling, touring, mountain biking and BMX, as well as kids and women’s specific versions.

Considerations When Buying Best Bike Helmets

Safety Standards

Do not buy a helmet if it does not conform to international and local safety standards. In the USA the CPSC regulates which helmets can be sold and the EN 1078 is the European standard. Other countries such as Australia, New Zealand, and Japan have their own standards as well.

Style of Cycling

Different types of cycling have different helmet needs. A mountain bike helmet will protect more or all of the head and will be heavier as a trade off for more protection. Mountain bike helmets commonly come with a visor to keep sun, rain, and branches out of the rider’s eyes. A road helmet will be very well ventilated and lightweight.


More vents will keep your head cool but will usually provide less protection.

Comfort, Fit and Weight

A heavy helmet will become uncomfortable after a couple of hours. Likewise, if the helmet is too small or the padding too big, the pressure on your head will give you a headache. A helmet must fit correctly to protect you. If it is too small or large, it will move around in a crash and not protect you. The straps must be easily adjustable to get the correct fit. Not everyone has the same head shape and you will find that some helmets are oval while others are more spherical.


Expanded polystyrene is the most common material used in helmets and is bonded to an outer shell that prevents the liner cracking. Some modern mountain bike helmets use the MIPS system or similar to provide extra protection from rotational forces. See the end of the article for an explanation of MIPS and the benefits of it.


Lighter helmets and better protection will cost more money, although all helmets on sale will protect you because they must conform to international and local safety standards.

Extra Features

If you use a GoPro or want to go night riding, you will appreciate helmets with built in mounts. Some manufacturers offer a crash replacement policy so you can get a new helmet at a discount if you do crash. If you think you are likely to crash (mountain bikers or BMX riders for example), it is worth paying more for a helmet with a replacement policy.

How to Fit a Helmet

It is no good owning a helmet if it is not set up properly. First, you need to select the right shape and size for your head. Measure around your temple and look at the manufacturer’s size chart to determine which size you need.

To fit a new helmet, first, place it on your head. It should feel reasonably snug. Add or remove pads to customize the fit and tighten the retainer at the back until it sits on your head comfortably. It should now feel snug without applying any pressure. To test if it fits at this stage, keep the straps undone and tip your head upside down. Be ready to catch the helmet if it falls off. If the helmet fits properly, then it will stay put.

The next step is to adjust the straps. First, open the side buckles and move them so that they sit below your ears. You want them to be as close as possible to your earlobes without actually touching them. Do up the buckles. Next, adjust the chin clip or buckle so that it can be closed comfortably. You should be able to easily slide a finger between the strap and your chin but no more. Any tighter will be uncomfortable and could restrict your movement, breathing or even ability to swallow.

11. Bell Super 2R

Bell Super 2RPerfect for trail riders who sometimes need a bit more protection in extreme situations, this helmet converts between a half shell and full face.

When the chin bar is installed it does not conform to the ASTM full-face safety standard, but will still protect your face in a crash. The top part of the helmet is well ventilated and comfortable to wear. Attaching the chin guard is a quick procedure. Removing it again is not quite as fast as the clasps can need a bit of muscle to move. This is a consequence of the secure fit though, so not really a problem.

Although slightly on the heavy side, the Super 2R is better ventilated and allows easier breathing than dedicated full face helmets. Goggles fit nicely and there is also a MIPS version available for more protection at a slightly higher price.


  • Full face protection that can be worn as a half shell.


  • Heavy

What is MIPS?

Multidirectional Impact Protection Support, or MIPS for short, is a Swedish technology developed in the 90’s but has only recently found its way into bicycle helmets.

MIPS is a layer attached to the foam that helps protect the head from rotational forces that are commonly experienced in bike crashes. The MIPS layer can move separately from the outer layer, ensuring as much of the impact gets absorbed by the helmet rather than reaching your head.

A MIPS liner will bump up the price of a helmet and is worth the investment if you can afford it. However, the most important factor deciding whether a helmet will protect you is whether it fits properly. Do not be afraid to choose a helmet without MIPS if it fits better than one with it.
