Abstract: A method of chamfering an aperture in a reel member of a tensioning system for an article of footwear is disclosed. The tensioning system includes a reel member configured to rotate about a central axis. The reel member includes a shaft and at least one flange disposed along the shaft. The flange includes an aperture extending through the flange. The aperture is configured to receive a lace. The reel member can tighten the tensioning system by winding the lace around portions of the shaft disposed on both sides of the at least one flange.

Abstract: A wheel assembly is provided, particularly for use with a vehicle, for example a scooter or a bicycle and the like, for operation in both eccentric and concentric modes. The wheel rim of the assembly rotatably and concentrically supports a wheel hub thereon. An offset axle is supported on the wheel hub radially spaced from the central axis of the wheel for rotation with the wheel hub relative to the wheel rim about the central axis.

Abstract: An eccentric device of a gear set of a bicycle is described. The device includes a braking disk, a transmission gears set, an eccentric shaft set and a hub assembly. The eccentric shaft set is disposed within the hub assembly and can 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. The shifting effect is thereby 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. The rear wheel will be oscillated upward and downward when it is rotated.

Abstract: A bicycle is provided with wheels whose axle hubs are eccentric with respect to the wheel geometric center. A bicycle with such wheels and in forward motion will cause its rider to also oscillate up and down as the wheel axles rise and fall due to the wheel eccentricity. The purpose of such motions superposed on the forward travel motion is to exercise the rider's body more effectively by subjecting it to accelerations similar to those experienced in riding a horse.
