The Smart Electric Bicycle Controller is a developed controller that improves the existing pedal-assist technologies. In this study, the Smart Motor controller uses an alternative model-based algorithm for controlling a pedal-assisted bike, Coast down Test method was implemented to determine the electric bicycle parameters for the implementation of the algorithm. The model based algorithm allows the effects of the external environment and differences of riding style and rider profile to control the power provided by the motor. Sensors such as voltage sensor, current sensor, cadence sensor, speed sensor, and torque sensor were used for power ratio management between motor power and human power riding at different speeds using 3 throttle modes. The smart motor controller is a microcontroller-operated, which is Arduino development board. Data were obtained between the actual motor power vs target motor power using the 3 throttle modes: Sport, Mid and Executive. Motor and human power control accuracies varies between the rider profile, riding sytle and road conditions through different speed implementation.
