Abstract: The present invention relates to an eccentric device of the gear set of bicycle of the type which includes a braking disk, a transmission gears set, an eccentric shafts set, and a hub assembly. The eccentric shafts set is disposed within the hub assembly and it could be rotated with respect to the hub assembly. When the eccentric shaft is located at the center of the hub assembly, the hub assembly can be readily rotated by the flywheel. When the braking disk is braked, the eccentric shafts set can be rotated with respect to the hub assembly through the transmission gears set. A shifting effect can be therefore attained. The shifting displacement can be readily controlled by the braking time of the braking disk. When the braking disk is released, the hub assembly can be readily rotated as centered on the eccentric shafts. Accordingly, the rear wheel will be oscillated upward and downward when it is rotated. The present invention can be readily shifted between the normal or shifted modes. The shifting displacement can be readily adjusted.
