Abstract: Embodiments of a bicycle riding training system are disclosed. The system includes a crank assembly that is removable from the bicycle without disruption of the sprocket and chain. The invented system comprises coaxial shafts that rotate preferably together in a hub bearing assembly. The coaxial shafts preferably include an external shaft within the bearing retainer cups of a bicycle frame bottom hub assembly and an internal shaft that connects to the crank arms.

Abstract: A single-use damping mechanism. A piston assembly fits within a chamber defined by a piston receiving member. The distal end of the piston receiving member includes a first and second passages which are disposed in fluidic series between the chamber and the ambient air. The first, inner passage is relatively small and controls the damping time of the mechanism. The second, outer passage is relatively large and holds a sealing assembly that prevents fluid from escaping from the chamber, through the first passage, until the mechanism is to be used. The piston assembly includes a pressure relief assembly, which comprises a cavity filled with a compressible material, into and out of which fluid can flow as necessary to protect the mechanism from temperature related pressure changes, and yet which does not interfere with the damping characteristics of the mechanism.

Abstract: An aluminum alloy brake disc body for a disc brake device is provided with a metal layer of a high wear-resistance. The high wear-resistance metal layer is configured to reduce thermal stresses within the aluminum alloy brake disc body so as to inhibit warping, bending or flexing of the brake disc when heated during braking. The high wear-resistant metal layer also is applied to the aluminum alloy brake disc body in a manner reducing manufacturing costs. In one mode, a plating layer made of a metal having a high wear-resistance is formed on a frictional surface of an aluminum alloy brake disc body. Cracks in the form of a fine network are formed in the whole area of the plating layer. The cracks can be formed by a plating process, by nitrosulphurization, by heating, by burnishing or by use of the plated component. The cracks advantageously provide for expansion between the individual metal fragments and, thus, create an expandable plated wear surface.

Abstract: A CVT has primary and secondary pulleys, and a control unit for controlling the transmission ratio by controlling the line pressure applied to the first and secondary pulleys. The control unit calculates a standard step position of a step motor corresponding to the target transmission ratio and provides a command signal representative of the difference between the standard step position and the current position of the step motor. A shift control valve actuated by the step motor controls the pressure to be applied to the primary pulley. The control unit compares the actual transmission ratio with the target transmission ratio, and if the shift is not completed, the control unit commands an additional step number. Unless the shift to the HI side is accomplished when the additional step number reaches the threshold value, the line pressure is increased to achieve the shift.
