Unlike traditional bike lights, which project light in only one direction, Revolights cast 360 degrees of illumination, making it much easier for others to sight the rider. This improves safety tremendously, as most nighttime bike-car collisions are due to inadequate side visibility.
The patented Revolights bike lighting system consists of two narrow rings of LEDs that mount directly to each wheel using a series of clips and ring spacers. Lithium-ion batteries, bracket-mounted to the front and rear hub, supply power to the LEDs. The batteries are slim and lightweight, and can be charged via USB. A small, fork-mounted magnet and an integrated accelerometer provide speed and orientation data to the rings. This allows the LEDs to illuminate only when oriented at the front or rear of the bicycle.
The first idea for the lights came to Kent, the inventor, while he was riding his bike home from grad school at Stanford. The thought was, if I'm using this handlebar mounted light mainly to light the road ahead of me, why wouldn't the light be a bit closer to the ground. So from there the idea was born, yet we quickly realized the benefits beyond the simple "near-the-ground" road illumination.
We utilized what we consider an open development process on Kickstarter.com. Our small team of six took the idea from concept to reality in an accelerated 11 month timeline. During the design phase of development we regularly incorporated our Kickstarter Backer’s feedback. With our initial Kickstarter funding we were able to do a lot to forward development, including: prototype creation, production tooling, and vendor selection.
