A portable power generation system includes a power generation unit and a monitoring unit. The power generation unit is detachable from the wheeled occupant apparatus and includes a pivoting arm, a rotating gear, and a control unit. The rotating gear is in communication with the wheeled occupant apparatus and is configured to rotate upon movement of the wheeled occupant apparatus, such that rotation of the rotating gear induces an electrical power generation effect. The control unit is in communication with the rotating gear through the pivoting arm and regulates the storage and transmission of electrical power. The monitoring unit is in electrical communication with the power generation unit and dispenses electrical power and provides user data to a user.
