Helmet survey

[classic33]

Looking at a few answers a few people are confused by the meaning of multi-impact, when a helmet basically can be hit several times from a branch-to crashing and your heading hitting the floor- and it still remains safe to use no matter how many times this happens- it is shown after an EPS (polystyrene) helmet what is pretty much in every helmet is dropped just, it loses it integrity on the inside of the helmet even though the outside shell looks fine and could/would fail EU standard tests- Whilst a multi-impact would still pass no matter how many time your drop it, so for off-roading this could be a better helmet maybe?

Why, if it'd survive multi impacts, does the one linked to, have a lifetime replacement?

Limit on the number and severity of impacts maybe.

@jack9266 If you haven't already guessed, helmets can be a polarising subject. Have a read here.https://www.cyclechat.net/threads/the-cyclechat-helmet-debate-thread.187059/post-5483631

Current thin shell cycle helmets are designed for single impact collisions (unless each individual impact strikes a different/fresh bit of the helmet with each hit). Current tech uses the predictable rate of compression of high density expanded polystyrene to deliver it's impact absorption. So your 'multi-impact' design will require a new technology. Polystyrene injection moulding is cheap (once you've covered the cost of the mould). Your new technology will need to be able to compete on price. Will your 'multi-impact' technology be such an attractive selling point that you'll either be able to sell enough units to bring the price down (economies of scale) - or charge more for it? But - assuming you can devise a whole new shock absorbing technology - the big sticking point is: how are you going to make the outer shell so strong that it'll survive multiple collisions with whatever you throw it at? It'll need to be *extremely* resistant to abrasion and impact - whilst remaining light and cheap.

Good luck.

Even a motorcycle crash helmet that has had an impact should be thrown away and replaced.

Or sold on Ebay to a schmuck.

Next, a survey on whether you still use stabilizers on your bike...

Road or MTB?

Looking back at my survey it probably does not cover everything so i will get a new one sorted for you lucky people.....

Some people ride off road and on road and will not always wear a helmet, your new survey does not allow for that.

Done

Are these surveys for product research, academic attainment, or just curiosity on your part?
What will you do with the results?

 

[jack9266]

Product research-

 

[Slioch]

Done.

Sorry to be pedantic, but Q3 also needs a "both" option.
