Disclosed is an energy harvesting power-assist system and method for human powered light vehicles. The power-assist system comprises a drive mechanism, one or more motor/generators and a high capacity storage device. The system continuously harvests and stores energy which is converted to motion by the motors, providing additional power to the user's pedaling. A controller determines the amount of pedal assist based on a user's preset value, and manages the charge and discharge of the high capacity storage device. As such, the system does not require any other external energy source, and the storage device never needs external charging under the described usage cases.
