W HELMET / helmet

Many bicycle riders are dangerously using roads with cars because there are not enough bicycle paths in many areas. I would like to suggest a smart solution, which would be to use eco-friendly energy to improve the bicycle user's safety.

W-HELMET is an eco-friendly safety gear that uses wind energy to improve the rider's safety while riding the bike.

1. While the bicycle runs, the front side of the fan is rotated by the wind.
2. The rotating kinetic energy is changed into electrical energy, which is stored in a charger behind the fan.
3. This supplied electricity illuminates the safety LED (Light-Emitting Diode) light.
