Good idea but it could use a little help in the design department. The prototype looks a bit silly.

Or, indeed, don't use helmets. It doesn't seen to eradicate the Dutch population.

Oooooh. Stylish!

Bicycle helmets cost lives. They create the impression that bike riding is dangerous resulting in parents discouraging their children from riding bikes reducing the exercise that their children get leading to premature deaths costing more lifetime lost than than the helmets save.

And I thought I looked like a geek with a regular bike helmet.

SlowKlue must be a Tea Party Pinhead. While this design at best has an unfortunate appearance that will give life to the name "Melon Head" helmets are essential. Bike helmets have two functions, A: They visibly define the shape of a rider, and B: They protect the rider in most ordinary spills. Note that I listed visibility first. It is very more important that riders be perceived by surrounding traffic as a rider in that traffic. The second feature is that a helmet will do an excellent job of protecting a rider from head & neck injuries in most falls. Not wearing a helmet results in death or severe head & spinal injury in about 85% of falls. I have regularly used bikes as transportation for over forty years and I do not get on a bike without a helmet on. Riders who wear helmets know they have something to protect.

re; StWils
It was an English doctor who did the study.
All the helmet protect you from is falling over. Do you wear a helmet when you walk.
Adding weight to the head increases neck injuries.

Hmmm....but then I don't walk at 20mph either. Along with cars and other vehicles around me.
I can't imagine a bicycle helmet causing neck injuries. They weigh very little. Otherwise why are more motorcyclists out there with neck injuries. Those helmets weigh pounds more than a bicycle helmet.

re; VoiceofReason
The helmet does not protect from those 20 miles per hour either. Motor cycle helmets cause more neck injuries than bicycle helmets but remember the straw that broke the camel's back not because it was heavy but because it added that tiny bit of extra strain.

Bike helmets and the people that insist others use them are an indication of much of what is wrong with western society.
The only possible justification for wearing a bike helmet is the slight performance increase from better aerodynamics which frankly is not worth looking like a retard for.
RE StWils "A: They visibly define the shape of a rider ...Note that I listed visibility first"
STWils , Do you have a flag mounted to your bike? Do you wear a high visibility reflective vest every time you ride? Have you mounted strobing LED's to your head while you ride? All of these measure are more effective than a helmet for increasing visibility.
Also you state "Not wearing a helmet results in death or severe head & spinal injury in about 85% of falls" Assuming that every child that learns to ride a bike falls only once 85 percent of the population that learned to ride before 1985 should be traumatized by the carnage caused by bicycles.
If that figure was anywhere near correct China would have been entirely depopulated during the cultural revolution.
