Abstract: This paper describes about the need and the various architecture of Electric Bike (E-bike). Among the various electric propulsion sources available, the performance study of Brushless DC (BLDC) motor for an electrically assisted bicycle (E-Bike) is carried out under certain operating conditions. In order to determine the operating speed and to achieve a suitable gear ratio, the motor is operated at different duty ratios whereby the operating voltage and speed of rotation of the motor is varied. The motor is loaded during the various test speeds considered. Based on the performance of the motor and the norms set by Central Motor Vehicle Rules (CMVR) of India, the torque delivered by the motor is computed through experimentation. The characteristics graphs have been plotted against different parameters. Depending on the torque values at the recommended power, the motor operating speed, voltage and currents were identified. Suitable gear ratios have been identified to match the performance of the motor with the e-bike performance requisite leading to better performance of the E-Bike propulsion system.
