9 Best Bike Helmets For Big Heads in 2022


Finding a quality bicycle helmet when you have a head that is larger than everyone else’s can often be a challenge and extremely frustrating. In fact, just researching bike helmets for big heads was a challenge in itself.

The objective was to find extra-large bike helmets at the top end of the spectrum, like 68 to 70 cm (26.7 – 27.5 inches), however every time we thought that we were onto something positive it turned out to be nothing more than smoke and mirrors.

Fortunately for cyclists looking for helmets for larger heads, some of the biggest names in bicycle helmets, like Bell, Bontrager, Giro, and Smith Optics manufacture larger-sized helmets.

Extra Large Bike Helmets

The size of extra-large bike helmets is relative to the size of your head. Some people may consider a 61cm bike helmet to be an extra-large size, while many others would struggle to try to get a 64cm bike helmet onto their heads.

In this article, we bring to you the largest sizes of bicycle helmets on the market today, which currently range up to 66cm (26 inches).

Whether a 66cm bike helmet is considered an XL or an XXL bike helmet doesn’t really matter. What matters is that you can find a helmet that will fit your head comfortably without pinching or giving you a headache.

Even if the oversized helmet that you are searching for is only 60cm, then you will still find several here that will fit your big head. Check the chart below to see how many different helmets are available for your head size.

Finding That Elusive Oversized Helmet

Different helmet manufacturers use different terminology to name their sizes, so we are basing our sizing on centimeters and inches. If you are looking for an XL bike helmet, XXL bike helmet, XXXL bike helmet, or similar sizing, then you are sure to find something suitable below.

To make your search a little easier, we have ordered the list by size, largest first. Within each size group, there are several different helmets sorted alphabetically.

Before you start looking for an oversized helmet to fit your head, please be sure about your head size. See our article ‘How To Know Your Helmet Size’ to learn more about getting the correct size for your head.

A properly fitted helmet is the most important aspect of helmet safety. A helmet that is too loose or too tight will not be comfortable and may not protect your head adequately if you have an accident.

Bike Helmets For Big Heads Larger Than 67 cm (26.4 Inches)

As previously mentioned, we did try to find something in the range of 68 to 70cm worthy of addition to this list but couldn’t find anything except hype, misinformation, and typos.

If you can’t find a bike helmet for your head size on this page, I would suggest trying to contact a couple of the larger helmet manufacturers and hound them into making something in your size.

Bontrager already makes 66 cm helmets, Bell and Giro make 65cm helmets, so it can’t be totally out of the realm for them to make a larger size helmet. Heck, even Smith Optics makes 67cm ski helmets.

Here’s a recent addition to the Bontrager helmet line-up, the Bontrager Circuit WaveCel Road Bike Helmet. If that sounds familiar, that’s because around 4 years ago Bontrager released the Circuit MIPS cycling helmet.

That’s one of the great things about Bontrager, they like to keep both the MIPS fans happy as well as the WaveCel supporters. That way, both camps can enjoy the best that Bontrager has to offer.

The Circuit Wavecel comes with the ever-popular BOA® Fit System which can be adjusted with one hand. On the inside is moisture-wicking, washable pads for a comfortable ride.

The helmet straps are fixed in such a way that they will always sit flat against your head rather than getting twisted.

Main features summary:

  • WaveCel Rotational Impact Protection

  • CPSC certification

What do the Reviews have to say about the Bontrager Circuit WaveCel road bike helmet?

Mostly all good and positive, however, there are a few people not keen on the WaveCel as it makes the helmet heavier, and it also makes the helmet hot and uncomfortable in the summer.

Otherwise, it’s a good, sturdy helmet from a trusted brand whose helmets tend to rate very well in Virginia Tech’s independent testing.

Very little in the way of negative reviews, but one buyer claimed that the fit adjuster was broken on arrival so he went with a different brand helmet instead. And one other reviewer who was generally happy with the helmet said that the straps could be a little longer.

Frequently Asked Questions

Q. What is the largest size bike helmet?

A. Currently, the largest size bike helmet that we can find has a head circumference of 66cm (26 inches). In the recent past, there have been 67cm and 68cm bike helmets available, however, helmet manufacturers would much prefer to sell thousands of smaller-sized helmets to consumers with regular-sized heads than a few hundred bike helmets to a small percentage of people with oversized heads.

When searching online for larger-sized helmets, you may find websites that claim to have helmets to fit a 68cm head. However, upon delivery of the helmet, you will most likely find that it is far smaller than the size advertised.

Smith Optics make bicycle helmets up to 65cm, yet they make extra-large Ski helmets up to 67cm. Then there are motorcycle helmets available up to 72cm (HJC has 5X-Large helmets up to 70cm, and Vega has 6X-Large motorcycle helmets up to 72cm).

Q. How big is an XL bike helmet?

A. Helmet manufacturers are not compelled to follow a standard sizing protocol, so as a result, the XL bike helmets from one manufacturer may be 66cm (26 inches), while an XL bike helmet from another manufacturer may be only 64cm (25.2 inches). The XL bike helmet size from other manufacturers may be completely different again.

Q. Should a bike helmet move on your head?

A. Most Definitely Not! If your bike helmet can move when you shake your head, imagine how much it could move if you are involved in an accident and your helmet and head hit the ground. A bike helmet that can move about will offer little to no protection for your head.

Your bike helmet should be snug and comfortable. If your bike helmet can move around or up and down when you shake your head around, then it is too loose. If your bike helmet gives you a headache or leaves red pressure marks on your head, then it is too tight. Please read How Should A Bike Helmet Fit for more details on proper bike helmet fitting.
