Bike Helmet That Stinks When Damaged

Bike Helmet That Stinks When Damaged: Cool or Not?

Anytime your bike helmet hits a hard surface it becomes less effective at protecting your noggin. Hit it hard or often enough and you'll render it completely useless — sometimes without even knowing until it's too late. Well, researchers at Germany's Fraunhofer Institute have come up with a solution in the form of a helmet stink bomb. If the protective material in your helmet is compromised, an odorous gas will be released alerting you to get a new one. Plus I imagine that once your helmet smells gross, you're not going to want to keep it around anyway. The helmets are currently in the testing stages so no final word on when they go live. Will you wear one when it's ready?

I think it's kind of gross. I mean, it's good that it reminds you to change the helmet, but I think a color-changing one would be just as effective. What's next, toothbrushes that start to taste nasty when you need to replace them?

I agree it would be nice if there were another way to tell when to replace your helmet that was less... gross. I would imagine that you might keep an old helmet around as backup or a "just in case" and this would prohibit that.

I think color changing would be just as effective and more pleasant, but I'd hazard a guess that they would be doing that already if it were as "easy" as making the helmet smell. I would love something like this - unless you've been in an accident, it's hard to know when to replace your helmet. Like if you drop it a few times, is it still OK or do you need a new one? Sometimes it's hard to know.

I applaud people getting back on their bikes after a fall bad enough to compromise their helmet. I like the objective of these helmets, however I think the goal can be achieved without odor. Color changing, ink emitting, etc. may be just as effective.

It's not a bad idea, but it's ALWAYS a good idea to replace your helmet if you've been in any type of accident.

Falling off of your bike is bad enough. I would hate for that to be accompanied by a bad odor.
