Bicycle helmet brake interlock   (+4, -9)  [vote for, against]
Re: Cycling

Trying to persuade a teenager to wear a deeply uncool cycle helmet whilst cycling is like persuading an anchovy to wear a tutu.
Even explaining that it could just save him from spending the rest of his life in a wheelchair, or eating meals through a straw is simply a waste of breath.
Teenagers are invincible. Fact.

This idea uses small cable reels which measure the amount of cable paid out, and when the correct amount is reached, release the brake handles on the bicycle.
The correct amount is, of course, the length of cable from the handlebars to the small hooks on the peak of the cycle helmet.
If too much cable is paid out, the brakes are automatically applied, to stop the bike hitting the rider after he/she has been thrown over the handlebars.

and then there is the psychology of the driver...

Hmmmm .... if the cable is sufficently strong, and well attached, and the helmet well strapped on, then it's possible that given certain sets of circumstances the momentum of the bicycle and rider [once separated] could interact to snap the rider's neck like a dry twig.

So if I lean in to pump up a steep hill, the brakes lock? Hmmm, maybe this needs a redesign. Though this really is even cooler than the elastic thru the sleeves so they don't loose their glove trick.

How about you rivet a magnet in their ear and then have a magnetic switch on the helmet that sends a radio signal to release the brakes? Wait they'd just get another magnet. So how about just riviting the helmet on their heads? No, that might be traumatizing. How about checking in on your kids and taking the bike away if they don't wear a helmet? Hmmm, parenting, that might work.

// ones in which a helmet is useless. //

Not so; the helmet can be used to remove the remains of the suicyclist from the scene of the incident; a sort of garishly-decorated funerary urn.

The solution is either to make cycle helmets compulsory or, better yet, to let kids enjoy a few moments of life on the wild side and go helmetless. Perhaps, until these one of these solutions is adopted, you could simply Araldite the helmet onto your child's precious cranium?

Since most of those helmets are filled with foam, why not just spray a thick coating of polyisocyanate on their heads; comb and form it into a style before it fully hardens; paint it a suitable colour et voila - a permanent helmet.

And your gripe with that would be....?

This could lead somewhere, given the amount of hair sculpting products he ladles on.
Maybe I could substitute some two-parter foam product

Well, my gripe is that I am dutch. We do NOT wear a helmet on a bike. Period. Makes you look like a sissy. This invention would make one look like a supersissy. We dutch would rather die than look like a sissy, and we don't because we know how to ride a bike properly and we know how to crash with our bikes properly.

The secret is to let go of the steering and breathe out.

Ah, yes. The same philosophy which made the VOC such a stalwart in today's markets. Batavia your facts right if you want to counter that one.

Why do the brakes need to be actuated after a fall? In my experience, any crash strong enough to throw the rider will also knock the bike over, meaning it stops immediately anyway.
-- 5th Earth, Dec 31 2007

Or in my case, not realizing how powerful the brakes were on my new bike, promptly halt the bike and throw me a good distance down the hill.
