Fireflywheel / Environmental solutions


When analysing the functions of a bike, we found out a principle within it called “ centrifugal force”. It is a force that draws a rotating body away from the center of rotation, in which we converted it into the energy to power up our lights on the wheel.
As a result, it increases the visibility of bikers at night when cycling without the need of batteries. Not only do it keep the biker safe, it is also environmentally friendly.

The central part of product is hollow. It makes us easy to install on the bicycles’ wheels. When bicycles’ wheels roll, LED lights in hollow tubes will shine for illumination need.
