Utility model content

The utility model provides a novel environment-friendly and energy-saving bicycle brake device. Conventional bicycle tail lights have no light source, and can only display light after relying on external light sources to irradiate and reflect light. Driving at night, in the absence of light, it is difficult for the rider behind to find someone riding in front, which is very unsafe. The purpose of this design is to provide a new type of energy-saving bicycle brake light that utilizes the energy conversion when the bicycle brakes to provide electric energy for the bicycle taillights, and can continuously emit light when braking.
