Even as an adult who understands the risks, I hate wearing a bike helmet, but do it anyways. Kids, however, aren't quite as understanding. So these fake helmet mohawks known as Fohawx are supposed to convince them that safety is cool.
Maybe it's because I haven't been seven-years-old for a while now, but I'm not convinced the younger version of myself would have thought these were cool enough to warrant wearing a helmet. But I also grew up in a time when giant throwable metal spikes called Lawn Darts were considered safe, so maybe I'm not the best person to ask.
At the moment the $20 Fohawx are available in five different designs, including brightly colored mohawks that stand up, and hanging 'dredlox'. And they attach to the helmet via a strip of velcro so they can be easily removed once your kid gets to the age when being cool is actually important to them. [Fohawx via Coolest Gadgets]
