Structure of Integrated Device for Bicycle Safe Braking and Smart Directional Warning Lights

In this study, we present the development of an integrated bicycle safe braking and smart directional warning light system, which is a combination of an advanced braking mechanism with intelligent directional signaling, to significantly enhance rider safety.The system addresses a common safety issue faced by cyclists and motorcyclists: loss of balance and potential flipping due to improper braking techniques, particularly when braking is applied first to the front wheel instead of the rear.Such improper operation often leads to dangerous falls and accidents.To mitigate this risk, the proposed system incorporates a safe braking mechanism that prioritizes rear-wheel braking before applying force to the front wheel.This braking sequence improves overall stability and control during deceleration.Furthermore, the system is integrated with a smart directional warning light function, enabling the brake controller to manage both braking and turn signaling simultaneously.The brake controller is designed to connect seamlessly with the bicycle frame, rider's helmet, and directional warning devices.When the rider initiates a turn-either left or right-while braking, the system automatically activates the corresponding directional warning signals.These visual alerts serve to notify nearby road users of the rider's intended movement, thereby enhancing situational awareness and reducing the likelihood of traffic accidents.Overall, the integration of safety braking with intelligent turn signaling provides a practical and effective solution for improving road safety, especially in urban commuting environments.
