An electronic automatically decoupling hub assembly for a bicycle having a rear suspension assembly (26, 38) that can articulate during use, the articulation causing a distance between a center chain sprocket and a rear wheel sprocket of the bicycle to change causing changes in chain tightness, the electronic automatically decoupling hub assembly being mountable on the rear wheel and to be driven by the rear wheel sprocket, the electronic automatically decoupling hub assembly comprising: an axle; a hub shell rotationally positioned about the axle; a bearing rotationally positioned about the axle; a rachet ring rotationally positioned about the bearing, the ratchet ring having at least one tooth therein; an inductor comprising at least one pawl to selectively engage or disengage with the at least one tooth of the ratchet ring; a seal to contain the at least one pawl within the electronic automatically decoupling hub assembly; a cassette body assembly coupled with the rachet ring; an end cap coupled with the cassette body assembly to prevent a contaminant entry into the electronic automatically decoupling hub assembly; a selective disengagement of the at least one pawl from the at least one tooth of the ratchet ring will cause the electronic automatically decoupling hub assembly to enter a freewheel state, and a selective engagement of the at least one pawl with the at least one tooth of the ratchet ring will cause the electronic automatically decoupling hub assembly to enter a force transfer state; and a controller inside the hub shell, the controller adapted to receive an input from a sensor positionable proximate a rear axle of the bicycle for sensing changes in terrain, and the controller adapted to provide at least one automatic signal to the inductor based on the input from the sensor, the at least one automatic signal causing the inductor to engage or disengage the at least one pawl with the at least one tooth of the ratchet ring. an axle; a hub shell rotationally positioned about the axle; a bearing rotationally positioned about the axle; a rachet ring rotationally positioned about the bearing, the ratchet ring having at least one tooth therein; an inductor comprising at least one pawl to selectively engage or disengage with the at least one tooth of the ratchet ring; a seal to contain the at least one pawl within the electronic automatically decoupling hub assembly; a cassette body assembly coupled with the rachet ring; an end cap coupled with the cassette body assembly to prevent a contaminant entry into the electronic automatically decoupling hub assembly; a selective disengagement of the at least one pawl from the at least one tooth of the ratchet ring will cause the electronic automatically decoupling hub assembly to enter a freewheel state, and a selective engagement of the at least one pawl with the at least one tooth of the ratchet ring will cause the electronic automatically decoupling hub assembly to enter a force transfer state; and a controller inside the hub shell, the controller adapted to receive an input from a sensor positionable proximate a rear axle of the bicycle for sensing changes in terrain, and the controller adapted to provide at least one automatic signal to the inductor based on the input from the sensor, the at least one automatic signal causing the inductor to engage or disengage the at least one pawl with the at least one tooth of the ratchet ring.
