Last Updated on 17 July 2024 by Cycloscope

Cool, Stylish, Safe. The 11 best bike helmets in 2024

for commuting, road cycling, bike touring, MTB, and bikepacking
Rated by Virginia Tech’s scientific study

When choosing the best bicycle helmet for your needs, you might first look at its aesthetics: is it cool and stylish or do I look like a cycling fool?

Of course, that’s not the main point, what matters the most is of course safety. In this article, we’ll describe the best helmets for road cycling, urban commuters, cycle touring, bikepacking, and MTB – not just the best according to us, but the top-rated by a scientific study.

Bicycle helmets are used to protect our heads and reduce the extent of injuries in the event of a fall, whether accidental or not.

Despite the controversy over the supposed uselessness of the helmet that rages in many countries, it is actually demonstrated by multiple authoritative studies, if any were needed, that a bicycle helmet can save your life.

Of course, a helmet will be more effective if it’s high-quality and produced by certified companies, that carry out serious and meticulous impact-resistance tests on their products.

The best cycle helmet brands, as we will see later, not only perform tests to obtain the mandatory certifications but also additional ones to guarantee a product that is as safe as possible.

Buying a helmet at an irresistible price but which has not been subjected to these tests is not advisable, at least if your goal is to be more protected.

A few years ago Virginia Tech, together with the Swedish Road Safety Institute, tested a large number of bike helmets, 188 to be precise, in the Virginia Tech Helmet Lab laboratories, and subsequently published a study and a ranking of the best bicycle helmets available on the market, in terms of strength, safety, and quality.

In this article, you will find the list of those that have been rated among the best helmets to reduce the risk of head injury.

11 Safest Helmets for Cycle Touring & Bikepacking

Here are our picks for 2024, as usual, based on our experience, people’s recommendations, and most importantly the Virginia Tech Ranking of the safest bicycle helmets for the current year.

1. Bontrager Rally MIPS

Safest MTB Cycling Helmet

The Rally MIPS features a tough and durable outer shell to shield your head from potential impacts. Inside, the helmet has an MIPS liner, which allows the helmet to rotate slightly around your head in the event of an angled impact, helping to redirect harmful rotational forces. This can be especially important in real-world crashes where impacts are rarely perfectly linear.

What sets the Rally MIPS apart is its blend of protection and comfort. It offers extended coverage at the back and sides of the head, which provides better overall protection for aggressive trail rides. The helmet also has a convenient adjustable visor that keeps the sun out of your eyes and offers extra protection from branches and debris.

Ventilation is key when you’re pushing the limits on the trail, and the Rally MIPS doesn’t disappoint. It features a generous number of vents to keep your head cool and comfortable during intense rides. The helmet also comes with a Boa Fit System, which ensures a snug and customizable fit. The Boa dial allows you to easily adjust the tension with one hand, even while riding, so you can get the perfect fit on the fly.

Lastly, comfort is a priority with the Bontrager Rally MIPS. The helmet is equipped with moisture-wicking padding that helps keep sweat under control and minimizes discomfort during longer rides. It’s also compatible with Bontrager’s Blendr accessory mount system, so you can easily attach lights, cameras, or other accessories to your helmet.

Other Bontrager helmets in the rankings are the WaveCel Spectrum Bontrager (34) – which also received 5 stars and is a cheaper model – and the Bontrager XXX WaveCel (63), a state-of-the-art road bike helmet, for those who want the best.

How to choose a bike helmet: the certifications/standard

As for bicycle helmets sold in the European Union, you should know that there is a European safety regulation, EN 1078, which certifies the products that reflect the established criteria. If you are interested and want to learn more, you can read the entire regulation here. To be certified, the product must bear the code EN 1078 on the label.

As we know, counterfeit products are found every day so we advise you to buy products from companies you know or that, like those in the list below, have been tested and certified by a body in charge of obtaining the CE marking.

The test required by the law provides, among other things, shock absorption tests that are performed at a speed of 5.42 m/s and 4.57 m/s. Additional tests are made on the restraint system (strap), which serves to verify that the helmet is kept in an adequate position during an accident.

CSI, a company of the IMQ group, is one of the most authoritative accredited bodies for the verification of the safety of helmets and their certification, which can also carry out additional tests to those required for CE marking, as stated by the president “the objective is to raise the safety bar and contribute to elevating standards for personal safety devices “.

For American products, on the other hand, “all helmets sold in the United States must be CPSC certified. This standard requires protection from catastrophic injuries in the case of extremely serious impacts, which are rare. Several helmets are certified by additional US standards. The evaluations indicate helmets exceeding the standards for snow sports (ASTM F2040) or skate (ASTM F1492)”.

Resistance test on bike helmets, how is it done?

There are different types of tests that are carried out in different countries, or geographical areas, to test the validity of a helmet but all follow more or less the same line. In the case of the study carried out by Virginia Tech, the technicians proceeded very simply, using the Mips technology, developed by some scientists at the Karolinska Hospital and the Royal Institute of Technology in Stockholm, Sweden.

After wearing a helmet on a fake head, they dropped it on a tilted anvil covered with sandpaper. When the helmet hit the anvil, some sensors measured its acceleration and rotation, two parameters associated with head injuries. The same test was carried out 6 times on each bike helmet model analyzed.

At this point, the helmets were evaluated by assigning a score from 1 to 5 stars based on the helmet’s ability to protect the head. The study that led to this ranking of the best helmets was funded by a non-profit association that deals with road safety and is therefore objective and without conflicts of interest.

“Our goal with these assessments is to provide cyclists with an evidence-based tool for making informed decisions on how to reduce the risk of injury,” said Steve Rowson, director of the Virginia Tech Helmet Lab.

Some tips for choosing the right helmet

According to a study conducted by the UPI, the Accident Prevention Office, wearing a helmet can reduce the risk of head injuries by 40% and greatly reduce their severity. For the helmet to do its job it is necessary, first of all, that it is the right size and that it is worn correctly.

If you want to buy a used helmet, make sure it doesn’t have any kind of wear and dent, it would still be advised to buy a new helmet. Indeed, it would be advisable to replace the helmet every 5 years.

“Statistics show that while the overall number of bicycle accidents in the country is declining, the number of fatal bike accidents is on the rise. In 2015, there were 45,000 reported bicycle accidents in the United States, down from 50,000 reported accidents in the prior year. However, the number of fatal accidents increased by more than 12 percent during this same time […] more than 70% of these accidents happen in urban environments.” – Source: peoplepoweredmovement.org

To begin with, purchase a helmet that is built in-mold and equipped with the MIPS safety system:

Construction of the In-Mold cycling helmet

With the in-mold construction, the sturdy polycarbonate outer shell is glued during the expansion of the EPS inner shell and absorbs shocks in one go. The helmet becomes harder without any additional weight. This production process also allows the creation of much better ventilation systems and air intakes. In-mold helmets are lighter than traditional helmets and have more effective ventilation systems.

MIPS security system

MIPS (Multi-Directional Impact Protection System) MIPS is a helical level system inside the helmet designed to slow down or prevent the amount of energy transmitted to the head or away from the head.

You can find the complete list of the analyzed helmets with the relative scores on the dedicated website of Virginia Tech.
