accelerated the development of intelligent and sustainable transportation systems. This project presents the design and implementation of a Smart Electric Bicycle with an Infotainment System, aimed at enhancing ride efficiency, user experience, and eco-friendly commuting, Promoting green transportation. The proposed system converts a conventional bicycle into an electric-powered vehicle using a Brushless DC (BLDC) motor, battery pack, and a custom-built motor controller for efficient speed and torque control. A joystickbased throttle regulates motor speed, while Hall sensors provide real-time feedback for precise motor commutation. The bicycle is integrated with a 7-inch infotainment unit developed using the Raspberry Pi 5 platform, featuring realtime ride statistics such as speed, battery status, distance covered, and navigation support. The system also offers smart functionalities like Bluetooth connectivity, multimedia control, and safety alerts, thereby enhancing usability and rider experience. Experimental analysis demonstrates smooth acceleration, reduced power losses, and improved comfort. The developed prototype achieves a range of approximately 46 km per charge, validating its potential as a low-cost, intelligent, and sustainable personal transportation solution.
A 7-inch touchscreen display hosts these five screens, offering an intuitive and visually appealing interface. The infotainment system is further enhanced with Bluetooth connectivity, media playback, and safety notifications, providing both functional and entertainment features. By integrating the real-time control capability of the ESP32 with the computational performance of the Raspberry Pi 5, the proposed system achieves efficient motor control, seamless data exchange, and a rich multimedia experience. This project demonstrates a cost-effective, scalable, and intelligent mobility solution that bridges the gap between electric propulsion and smart infotainment technology, contributing to the advancement of next-generation sustainable transportation systems.

Efficient and reliable BLDC motor control is fundamental to electric bicycle design. Several practical guides and papers emphasize three-phase BLDC topology, commutation strategies, and protection features (overcurrent, undervoltage), which are essential for safe e-bike operation. Industry application notes provide recommended hardware design considerations for battery interface, gate driving, and sensor integration for BLDC systems used in micro-mobility. These references inform the selection of switching devices, PWM schemes, and sensing required for a robust driver circuit in a retrofit e-bike. Texas Instruments+1
1.INTRODUCTION The continuous evolution of electric mobility has paved the way for sustainable and intelligent transportation systems, with electric bicycles (e-bikes) emerging as a practical and eco-friendly solution for modern commuting. E-bikes offer energy efficiency, low maintenance, and zero emissions, making them ideal for urban and short-distance travel. However, traditional e-bikes often lack advanced data monitoring, smart control, and user interface capabilities that enhance rider experience and operational efficiency.
