This paper presents the design and implementation of a cruise system for an electric bicycle integrated with Bluetooth-based auxiliary functions. The proposed system enables automatic speed locking when the rider maintains a constant throttle position for a predefined duration, thereby eliminating the need for continuous throttle input and reducing rider fatigue during long-distance travel. The cruise functionality is implemented using a standard BLDC motor controller, ensuring stable and efficient speed regulation under practical operating conditions. In addition to cruise control, a Bluetooth module is incorporated to provide wireless control of auxiliary features such as key ON/OFF, headlight operation, and horn activation through a mobile application. The cruise system and auxiliary control system operate independently, ensuring safety, reliability, and uninterrupted performance. The system continuously monitors brake and throttle inputs and automatically deactivates cruise mode when braking is applied or when any variation in throttle position is detected. Experimental results demonstrate that the proposed system maintains consistent speed and performs reliably under varying load conditions. The overall design is simple, cost-effective, and suitable for real-time implementation, making it an effective solution for enhancing performance and user convenience in modern electric bicycles.
