Arara vs Datacube.io

Arara is the battery-free wheel-mounted bicycle lighting system.

Arara is the bicycle lighting system that will never need a battery. The wheel-mounted lights are powered by strong neodymium magnets. When a bike’s wheel starts to spin, the lights move past the magnets and the generated electric energy is stored in the capacitor. When it's charged, Arara lights up.

Arara makes a bike easily recognizable from every angle at night, is available in variety of colors, is water-resistant, lightweight, and works at temperatures down to -15 degrees F.
