The increasing popularity of cycling, driven by environmental concerns and urban traffic congestion, has led to a rise in bicycle usage; however, bicycle theft remains a significant concern, particularly as traditional locks offer insufficient security. This study aimed to develop an advanced bicycle lock system called "Secure Cycle: Smart Bike Lock Security with Real-Time Alert System" to address these limitations. Utilizing developmental research and the Agile methodology, the study designed and implemented a smart lock integrating sensors such as accelerometers, gyroscopes, and force-sensitive resistors, combined with anomaly detection algorithms for real-time monitoring. The findings demonstrated the system's ability to successfully detect tampering attempts, send immediate alerts to users via a mobile application, and provide real-time GPS tracking to aid in theft recovery. Despite these promising outcomes, the study identified several limitations, including battery life constraints, dependency on network connectivity, potential environmental effects on sensor accuracy, increased costs, and cybersecurity vulnerabilities. Future research is recommended to explore enhancements that address these limitations in order to optimize the system’s reliability and usability.
