At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Giro Ethos Mips Helmet is a well-thought-out and functional commuter helmet with a few unusual extras thrown into the mix. In addition to the now-familiar Mips lining – designed to reduce rotational of your brain if you crash – Giro has also added front and rear lights that double up as indicators. Giro has clearly made a top-notch helmet for those of us who ride in built-up areas, but the price could be a problem for some. At £239 it's dearer than any of those in our best cycling helmets buyer's guide.

As someone that tries to do most of their riding away from the busy built-up areas, I was wondering how useful I would find a helmet like this – but I was very pleasantly surprised how beneficial I found Giro's new helmet.

The most obvious features are the front and rear lights that also double up as indicators. These have two strips of LEDs at the front with another two at the rear. Not only is this a lot of lighting but I was surprised how bright they were.

You get a choice of four modes: high and low power constant outputs and high and low flashing. These options should provide the right choice for most of us.

First off, having lights at the very top of your head when you're riding makes you very visible to other road users, as no matter how high or long someone's bonnet is, they will always be able to see your head when you are near them.

I thought this helmet was at its best when there was fog and when visibility was generally a bit questionable. I wore this in addition to using my normal bike lights and felt that the helmet boosted my visibility, making my presence even clearer to drivers.

A further feature is the indicator function that is activated by a remote-control button on the handlebar. This lets you indicate using your arms and the helmet simultaneoulsy, which you'd like to think makes it abundantly clear when you're about to turn….

The indicator function is well thought out too, with a tap on the left or right button of the remote setting off that side's indicator, using Bluetooth to connect to your lid's LEDs.

When you indicate, that side's front and rear LEDs turn from their standard white or red to an orange, with an almost sequential flash, in a similar way to how the Audi indicator works. It's great for drawing the attention of other road users.

The remote was easy to mount on my bar, using only a small rubber band to secure it. It comes with three different length straps, so one of them should fit just about any bar out there.

Safety is obviously a key factor in the design of any helmet, and this is also true of this Giro. It includes a Mips liner, which I love, and it's lower at the back than most bike helmets, in a similar vein to a mountain bike helmet.

One further feature that Giro has included is the easily removable peak. I wore the helmet in rain and while the peak is quite small, it made a noticeable difference to the amount of rain hitting my face. It also helped reduce glare from the sun, which is always a plus. And if you don't want the peak, a few poppers and it's off, looking more like a conventional road helmet.

The helmet and handlebar controller are both charged via USB-C ports, at the back of the helmet next to the power button, and at the back of the remote respectively. Both are hidden under weatherproof seals. The helmet battery takes two hours to recharge, the remote an hour.

You'll get between two and a half hours and 11 hours depending on the output you choose. The high output delivers 45 lumens at the front and 30 at the rear, with 25 and 10 lumens if you drop down. I personally used it in the low flashing mode most of the time, as this gave the longest run time.

While the Giro weighs in at 475g, which is certainly heavy for a road helmet, I found it comfortable even on rides up to five hours long, which is a testament how well the helmet is designed and how well the weight is distributed. I had no neck discomfort and really was pleasantly surprised how comfortable I found it.

The helmet straps are also very comfortable and with plenty of adjustability I could get them exactly where I wanted, with a magnetic buckle keeping it secure.

I found the helmet quite warm, which has proved ideal over winter, though when it comes to summer I imagine you might get warm, though its 12 vents do supply some cooling.

I was concerned that I might struggle to wear glasses with this helmet, but even though the rear of the helmet drops down behind your ears, I could wear not only my glasses but also the Oladance Open Ear Headphones I was testing at the time. This is great for commuters who also like wearing glasses.

I did run into one small problem, which is going to be less important for commuters, and that was the inability to slot the arms of my glasses into the helmet when I wasn't wearing them, as the vents aren't large enough.


At £239.99, this helmet is not exactly what you'd call cheap, though when you take the array of features into account, the price is more understandable. The price is up there with helmets such as the Specialized Prevail 3 that Stu liked and the Lazer Vento that George found light and airy, but these are aimed at very different markets.

It's more like-for-like competitors – helmets aimed at the cycle commuter – include the Bollé Eco React Mips helmet that Nick appreciated both for its comfort and sustainability credentials, which is £140.

The Kask Sintesi is an all-rounder commuter-cum-road-cum-gravel helmet at a bargain £90 that has passed Kask's own rotational impact test. Lara thought it was one of the best helmets around when she tested it.

The Abus Hud-Y has a rear LED and though Lara liked it a lot, she felt that the helmet's narrow fit might not suit all – and that it was expensive. At £129.99...

I enjoyed using this helmet much more than I had expected to. I found it comfortable and felt that the lights added to my night-time riding safety and thought the ability to indicate was great. I'd absolutely recommend this if you commute through built-up areas, and even if you're looking for additional safety and visibility for training rides.

Nice article. Nice to see roadcc covering the latest tech developments in helmets. 

However, I think the writer did forget about the Lumos Ultra for his comparisons. Their helmets are cheaper than the Giro here and looks better in my opinion. If i'm not mistaken, it's also lighter. I would love to see a proper comparison between the 2!

I don't see the point on indicators on bicycles currently. Unless LED indicators are accepted in law as one means of cyclists indicating their intention to other road users, you're liable to being at fault if you only use the indicator lights and don't signal with your arm and it results in a crash. Maybe it makes sense in other countries but not the UK. Besides all that you can't be certain they're actually working. I know my arm works...I guess thinking a bit more broadly there is a benefit for cyclists with disabilities.

I found them to be a useful addition to also indicating with my arm, with the way the roads are as of late, the more chance there is of someone seeing me, the happier I am! They also beep when they are indicating so you can know when they are on.

Fair enough, despite my GCSE in electronics it hadn't occurred to me that it's possible to wire a circuit up like that - duh!

Just don't forget to use your arm too 😉. Obviously you've already mentioned that of course. I do find it irritating when in certain situations I can't indicate with my arm as much as I would like due to wanting to be in control of the bike...especially on descents.
