Looks like a DIY, garage, I'm-too-cheap-to-buy-a-helmet-so-I'll-hack-one-together-myself helmet.

[soulspinner]

AHHHHHHHHH NO

[marciero]

Great. It was really getting expensive replacing my helmet after every crash.

[prototoast]

I impulse-buy new helmets more frequently than I crash them, so I don't think I'm the target audience for this product.

I like the feature of being packable but re-usable isn't high on my priority list. It's more than double the weight of the kask protone (randomly selected to determine what "normal" helmets weigh) and it looks like it's not the most well ventilated. I'll pass.

Looks like it hasn't been CPSC or Snell tested/approved yet.

One specific concern of mine, aside from the esthetics, is whether that helmet would skid on pavement.

If a rider has fallen at speed and is skidding on the pavement, it looks like the outside material, and the fittings, would cause the helmet to catch on pavement, which, in turn, might put additional strain on neck/back...

Several articles on helmets.org discuss this issue. Here's a link to one.

If a helmet's job is to absorb and redirect energy away from the head, it isn't a crazy leap to design a helmet which fits together in a certain way with attachments that can be "unattached" with a certain amount of force as a way of redirecting kinetic energy.

It is the same basic idea as crumple zones in a car.

That said, I'm not sure i want to be the guinea pig on this one. And, as mentioned above, the outer material looks like it would function as the opposite of MIPS. Maximum twisting force applied to the head.

I saw someone wearing a 40 year old Bell Biker the other day. If I see him again, I'll tell him about this helmet

I think the jury is still out on folding helmets, but re-usable (multi-impact) helmets are widely used in other fields. For example, football and hockey helmets are designed to be re-used, and there are some multi-impact skateboard helmets that also meet bicycle helmet impact standards.

I see the concern about whether this helmet would 'catch' on pavement causing rotational injuries. But the outer layer on bicycle helmets is only a thin veneer on crushable EPS foam, so many 'traditional' bicycle helmets face this same concern. If this helmet had a layer of a shearing material (such as Trek's Wavecel) it may reduce potential rotational accelerations (but of course, Wavecel is not re-usable).

Fugly. No deal.

[echappist]

their marketing department is full of BS. that, and the fact that bikeradar didn't do a thorough job investigating

quoted from the article

The Hedkayse ONE differs by instead being made from ‘Enkayse’, the brand’s own patented material.

Exactly what is Enkayse?

I asked Hedkayse if it could disclose exactly what Enkayse is but, understandably, it was not forthcoming in wanting to spill its trade secrets.

if it were truly patented (and i'm purposely writing this as a subjunctive), its designs should be readily available to the public. Anything less is false advertising.

Perhaps it is a misunderstanding, and it may be patent pending? It can take much longer to get a patent than it takes to build and test prototypes.

i just dug into it a bit more

2 issued in the GB; a few pending elsewhere

the issued GB patent appears to be for an expanded polyurethane material. Perhaps actual formulation of the polyurethane (ie.g. polyol and isocyanate used, density of foam, any chain extenders, etc) is a trade secret.
