Bike lights are essential to your safety if you’re riding a bike at night, and there’s nothing more annoying, or scarier, than the idea your light might suddenly shut down while you’re riding. The Magnic Light, and we assure you that’s not a typo, solves this problem, by taking batteries out of the equation.
Magnetic Dynamics
The Magnic Light is fairly simple. Attach a small item to your wheel, attach the light to your wheels magnetically, and you’re golden. Yep, that’s really it; there’s no resistance like some charging kits, there’s no other stuff to add, there’s no battery backup you need to install, nothing. But how does something like this even work?
Foucault Is Calling
By using a physics phenomenon known as Foucault currents or eddy currents. Here’s how it works; you take a conductor and induce a magnetic field. Then, you start cycling that field. As you may have guessed, the faster you cycle the field, the more power is generated. The Magnic Light essentially take full advantage of the fact that you’re doing work by attaching a magnet to your wheel and using that to spin the generator inside the light. So, the faster you go, the more the magnet spins, the faster the field cycles, and the more power you generate. All without losing resistance. Pretty neat, huh?
Magneto Would Be Jealous
If you’re sick of your bike light dying, or simply want to save some money on batteries, the Magnic Light is going to be your best bet. And, if the Kickstarter hits a certain level, it’ll even come with an anti-theft system, so you don’t get your lights swiped. Of course, you need to contribute to the Kickstarter first; you can get either front or rear lights, but if you want both it’ll be $180.
