Meet NEO: a cool bike light that keeps you visible at night and does not need batteries. As long as you can pedal, you will have a bike light to stay visible. There is a backup system in place just in case you get stuck in traffic. NEO is easy to mount and adjustable. Let’s not forget that there is no friction between NEO and the wheel of your bike.
The above video shows how NEO works. You can find out more about it on Kickstarter.
