Great gift

Bought this as a gift and it was well received, great product!

100 stars

I'm absolutely satisfied. Never had a better helmet.

First ride

Had first ride with mine today, seemed really nice, even though only have the option for medium and me having a "large" head it felt good - not overly heavy and reckon the rear light will be super useful come the dark evening rides.

Foldable Bike Helmet - Plico

super helmet, direct sevice thanks LID

LID Black Beanie

Great, stylish helmet

Really happy with it. I thought the helmet could be squeezed a little more than it does but it's not an issue - saves already space and fits into most bags and rucksacks. Most importantly it feels safe (sincerely hope I'll not have to test that) but also wears very comfortable.

Be Safe Be Seen

Be Safe Be Seen with a touch of added style. Purchased the Oakland orange, as it is very bright and can be seen for miles. The added rear light is much better in the flesh, than the adverts. Helmet fits very well on my head and in my rucksack with my laptop, when not in use.

My Lid Helmet

It fits well. I like the light on the back of the helmet. It looks very nice. It is light weight and comfortable.I am quite satisfied with this helmet!

Very comfortable

This is an excellent helmet. The expandable sides mean it fits the head snugly with minimal adjustment while fitting neatly into my backpack when I'm not riding. The clip-on light is a bonus; bright and with eye-catching blink patterns. All round a very good product.

Comfortable and Convenient

An easily storable Bicycle helmet with a fancy touch, the helmet is made from some pretty substantial feeling materials, and while its heavier than some helmets, its a very storable unit. It packs away to something close to but not quite half its full size, making this a great commuter type item, while at the same time meeting all the latest standards for bicycle helmets, and finally It comes with a rear facing red LED light (which is USB rechargeable) which is great at night or in low lights. Lastly for those that asked yes it is comfortable, so while this is not the cheapest of helmets it is a great utilitarian product. Highly recommended.

Innovative and comfortable

So, first thing you'll probably notice in the description of this helmet is that it 'folds'. I think squashes down a bit would be more accurate. The helmet is divided into tightly connected segments - you can pull them apart, but they'll return to shape. This allows a decent reduction in volume - see the picture for a comparison between the Plico and my old Giro helmet. It looks sleek off the head and it makes the helmet a little easier to transport when not worn. More importantly, for me, is that the adjustable size of the helmet means getting a good fit is really easy. The two methods of adjustability (velcro strap at the back, 4 different pins for the plastic frame on the sides) help with this. I've got a fairly small, narrow head, and I was able to get a good fit in a couple of minutes. The chin strap includes a soft wrapper for comfort. Style wise, it's possibly more reminiscent of older helmets and skate helmets than the ultra aerated style of most new helmets. I think this is probably a trade-off with the resizability - each segment has to be quite rigid and solid on its own. Personally, I think it looks pretty good, although all helmets are mushroomy on my head. The helmet is a little warm because of the solid segments. Yes, there are gaps between them, but the ventilation doesn't compare to most other perforated styles. Fortunately, I haven't had to test the toughness of the helmet yet, but it does meet safety standards - probably why the segments are so thick. The included light is genius, and I love that it's usb rechargeable. Overall, this is comfortable and clever commuter helmet that emphasises utility and looks over pure performance.

You have to try this to believe it!

I was very dubious about what is effectively a folding bike helmet, that currently is only available in one size, but once again I was wrong! This helmet is first of all unusually comfortable - fitting 4 out of five adults in our household easily and really cushioned against the head. The 'foldability' is what makes it especially comfy and the fit feels great. I haven't deliberately fallen on my head to rigorously test this, but I do get the sense that I am as protected as I would be with a standard model, in fact I can imagine how it might be a better form of protection because of the way it snuggly grabs my skull for a better fit than average. Inside there are strips front to back that are soft but that make good contact with your head. So, I hope you get the idea that is fits well and is a comfy helmet to wear. In addition it has a place at the rear where there is already attached a red light so that you get maximum visibility - this is a very positive safety feature, and you can have the light steady or flashing. I suppose I will never know for show without having an accident that this is at least as safe as the next helmet, but I certainly feel that it is and the confidence that I am given by that knowledge when riding is worth something. According to the manufacturers, there are plans to extend the range, but I really recommend that you try this because it is a really good helmet that adds comfort and security to your ride and I think you will like it as much as I did.


I have had a number of bicycle helmets. The fact that this one reduces in size does not make much of a difference in space needed to carry it. It is still fairly bulky. It feels very comfortable on and it certainly feels like it will provide good protection in the case of an accident. I hope that is one test I never have to comment on. Because of its design it does allow air in and that is welcomed. I prefer light coloured crash helmets as opposed to black because they make the cyclist easier to spot from front and rear and anything that does that has to be good. One thing I do like about this helmet is the rear facing LED light which you can has various functions.....just on, flashing etc. It is different. It looks good. It looks well designed. It appears well made. Impressed

Thoughtfully designed

The folding aspect of this helmet is great, although to be honest I didn't find it got loads smaller. But they have to operate within certain restrictions as they must ensure the helmet is stable enough to be safe. The helmet is lightweight but sturdy-feeling, made of a recycled material. I got the M/L. It's adjustable and comfortable even on my quite big head. The USB rechargeable light is a great bonus. It clips on the back and is really nicely and simply designed. The helmet comes in a cardboard box without unnecessary extra packaging, although there's a foam type bag wrapped around the helmet to protect it in transit. Maybe this can be excluded with a bit of paper padding or a cardboard cradle instead, which would be more environmentally friendly. Other than that though, I think it's great. There was a note from the manufacturer inside saying they're planning to design colourful raincovers to allow you to customise your helmet. I look forward to seeing those.

Great Protection Very Comfortable

I have been after one of these helmets since I first heard about them. I already have several cheaper helmets, but this is a class above all those. Firstly the helmet is polycarbonate similar to a hard hat or a riding helmet and not soft like some cycling helmets. The shock absorbing liner features removable velcro padded strips provides additional protection around the skull. The unique feature of the helmet is it elastically expands to provide the exactly the right fit around the head. The fit is extremely comfortable and can be worn for a prolonged period the ventilation holes ensures airflow around the top of the head. From a practical point of view the helmet collapses down to a slightly more compact for carrying and storage and weight less than half a kilo. There are 5 different bold colours to choose. A rear USB rechargeable clip-on light makes the rider easier to see in low light conditions. Overall very comfortable, great overall protection, clip on rear light, lightweight. Clever design allows the helmet to contract down when not being worn.

Nice design, could use a larger size.

I really like this helmet, unfortunately it is just on the brink of being to large for it. Hope they make a larger size in the future.


This is a really clever cycle helmet that adapts (within limits) to the size of your head, and reduces down again to make stowage and carrying easier. It's got a slightly Star Wars or Back to the Future II feel to it. We tried it on three people with different sizes heads, and it fit all of them perfectly, though there are (or will be) different versions for much larger or much smaller.

It's described as 'foldable', but that doesn't really do it justice. It doesn't fold up to something small. Rather, it's made with five padded sections which pull apart from each other. The aim isn't to make it as convenient as possible to carry, but to make it as safe as possible by providing the perfect fit to everyone in its size range. Although this is a cycling helmet, the same principle could easily be applied to caving helmets and climbing helmets, which are also typically hard to adjust but dangerous if not adjusted properly.
This is the first cycling helmet that has made me want to wear it, as opposed to seeing it as an unwarranted imposition.
Good job!

Great product; clever design

Fit was terrific, right out of the box. A larger size option is needed; I had hoped to give the helmet to my wife, but we found the helmet did not sit down fully and safely on her head when fully extended. In practice, the "accordion" extension of the helmet allows for a range of adjustment. Finish of the parts, straps, etc. are well executed.

(It's really orange too! If drivers can't see me in this helmet, they're really distracted!)

Nice helmet, but doesn't fold-down much

This helmet has nice look and feel, though personally I prefer bright colours to black for higher visibility. Fit is as expected for size. The rear light clips on and off and is as bright as you'd expect for the size - i.e. a handy extra light but you wouldn't want to rely on it as your main rear light in London. It's an add-on, so you could swap it for a different clip light in the future if you wanted. The folding part is not quite what you might expect - it folds down a bit but not really all that much - not to a degree that I'd personally find all that useful. Nice that it's eco-friendly.

Mixed feelings but I ended up liking it

I like the idea of a fold-up cycle helmet, as they really can be a pain to carry around everywhere when you're doing cycling errands, so I was hoping that this helmet would somehow have the ability to become really small, as well as looking fashionably iconic when on my head, of course. However, this wasn't the case - as you can see in the pictures, the helmet compresses inwards along the longest axis, making it narrower - and therefore taking up less space - but still long. The difference doesn't seem that great. The style takes a bit of getting used to - having had a look at the colours, I think black is probably the best. I get odd looks on the road - curiosity, I think. It weighs roughly 400g, so it's nice and light, as well as being strong. The air comes through well, and although still sweaty, it's better than normal designs. Comfort is fine, with a soft material sheath for the chinstrap available should you find that it chafes. I like the attachable light that comes with it, and clips onto the back. Overall, it's great that a British company is making innovative products like this - and I suspect that they have some other ones on the way. I like the helmet, but I would want it to be a lot more collapsible really which is probably impossible without sacrificing safety. I didn't like the white colour very much - I don't wear lycra, and it felt like it would be a good match for that style; the black one looks much better. It's tough and will protect well. The price maybe is the issue, as there will be many people out there that will come to the conclusion that the features offered aren't worth paying the extra for. But here's the truth - you pay extra because its COOL!

Comfortable and a break from the norm

As a seasoned commuter in Bristol it really annoys me how many cyclists I see on roads without helmets especially in busy traffic areas. I have never heard of the company Lid before receiving this cycle helmet but I appreciate any company who can make helmets more appealing to suit everyone and it looks like LID could help with their new style collapsible stylish helmets made with Eco friendly recycled EPS. These helmets are adjustable to your head and easily pop out in your hands and even more so when placed on your head which you think will feel tight but are anything but uncomfortable. They come in a multitude of colours which points back to my previous statement about them being designed to encourage more cyclists to wear them. My first impression was about the safety of the retractable element and had concerns over lastability and how they would fair in an accident vs a standard helmet at the same value. It is worth mentioning that the helmet does meet the common safety standard EN 1078 which is a European standard for cyclists and skaters and also CPSC (Voluntary). EN 1078 specifies requirements and test methods for bicycle helmets, skateboard and roller skate helmets. It covers helmet construction including field of vision, shock absorbing properties, retention system properties including chin strap and fastening devices, as well as marking and information. This safety standard is a basic standard you will find on most cycling helmets these days and we have moved away from what used to be Snell which was tested at a higher standard. This is more of a commuter and leisure cyclist helmet than anything I would expect long distant or competitive cyclist to wear. There is a removable light at the back that is chargeable via USB micro however no cable included. There is no slot for a front light or anywhere to attach a strapped camera should those who use them want to add them although I have been informed that there is a strong tape that can be used. At the m...

innovative and functional but is it just for gullible Hipsters

Is this a great idea. Introduce the notion that cycle helmets are cumbersome and difficult to carry around and then get marketing to create one that folds in on itself. It's a good idea however do we need it and is it recyclable? I will try it and see

Great idea, but make sure it actually fits you.

Foldable' is a bit too ambitious a word to describe this helmet, as it doesn't actually fold up. 'Collapsible' would be a better word to describe it, but perhaps the manufacturers can be forgiven for not wanting to use that description on something designed to protect your head. It's simply a multi-sectional helmet that pops open and closed. In it's closed format it will fit nicely into a shoulder bag or similar, but it's still a fairly bulky item to carry about, although nowhere near as cumbersome as a 'normal' helmet. The looks of the helmet are, to me, not great. It looks like an old-fashioned climbing helmet and sits very high on the head. I keep wanting to pull it down over my ears a bit more. On paper, this is a helmet that should fit me, but in practice I felt it was too small. I couldn't get a good fit, and the strap that goes across the back of your head was just too short to work for me. This strap also doesn't give anywhere near enough support, and any lively nodding of the head meant it just slides off the back of my head. I couldn't shake the sensation of just having it on top of my head, rather than actually wearing it. Of course, I might just have a weird shaped head, but there is little to no customisation of fit with this helmet, so it either works with your particular cerebral geometry or it doesn't. There are no pads or extra straps to get a snug fit. I would strongly suggest trying one on before buying, but it fits a treat on my partners head so it may well be I just have an odd shaped bonce. It's obviously aimed at commuter and casual cyclists, and is ideal if you use a lot of rental bikes. There is a supplied LED lamp that is really good, USB chargeable, that clips to the back. Look carefully in the box though, as I didn't even know it was there until it fell out when I was about to throw the box away. The ventilation is good, although not as much as a more serious racing helmet would have. The three segments in the helmet lea...

Collapsibilty USP is a gimmick.

Interesting design, and as a concept it works,but the reality is not really that brilliant. The size of the helmet when collapsed is the biggest flaw - there really isn't a great deal of difference. It moves in by an inch, maybe 2 at most, which still makes it too big for anything but a large rucksack, so not really sure I understand the point. In terms of comfort, it's ok, but nowhere near as snug and comfortable as my usual helmet. I have to note the positives too... The light is great, and the colour & finish are excellent.
