Mechanical Design and Stability Analysis of a Self- Balancing Bicycle

The proposed self-balancing electric cycle provides a compact and innovative approach to improving the stability and controllability of a two-wheeled vehicle. The design integrates a lightweight aluminum frame, two motorized wheels, a centrally mounted high-speed gyroscope, lithium battery, controller, motor driver, voltage sensor, power supply, charging unit, and remote-control system. The high-speed gyroscope is expected to generate stabilizing angular momentum, while the DC motors provide controlled propulsion and movement. The integrated electrical system enables efficient power distribution and convenient remote operation. Preliminary calculations indicate that the proposed prototype can achieve suitable motor power, wheel speed, and gyroscopic performance for experimental development. The project also provides an economical platform for studying mechanical stabilization, electric mobility, motor control, and energy management. During prototype development, particular attention should be given to gyroscope speed, flywheel mass, frame strength, weight distribution, motor torque, battery capacity, and safety. Experimental testing will be required to validate the theoretical calculations and determine actual stability, operating time, speed, and power consumption. Overall, the proposed cycle has significant potential for educational demonstrations, engineering research, personal mobility, and future development of intelligent self-balancing transportation systems.
