BiSafe: An IoT-Based Smart Bike Security System

Two-wheeler theft has emerged as a serious concern in urban and semi-urban regions, where effective yet affordable vehicle security solutions are limited. Conventional mechanical locks and basic alarm systems provide minimal protection and fail to support real-time monitoring or recovery assistance. Although advanced vehicle security solutions exist, they are often expensive, subscription-based, and targeted toward premium vehicles. This paper presents BiSafe, a low-cost, industry-oriented Internet of Things (IoT)- based smart bike security system designed to provide real-time theft detection, prevention, and recovery support. The proposed system integrates an ESP32 microcontroller, an EC200U LTE communication module, an MPU6050 motion sensor, an ESP32 CAM, a Global Positioning System (GPS) tracking system, and a relay-based engine immobilisation mechanism. A cross-platform application developed using Flutter enables users to configure geofencing parameters, monitor live vehicle location, receive instant alerts, and remotely disable the engine when unauthorised movement is detected. Cloud-based backend services are used for secure authentication, alert management, and real-time data storage. Experimental evaluation demonstrates that the proposed system delivers reliable performance and security features comparable to those of commercial solutions, while maintaining affordability and scalability.
