Abstract: A bicycle with a suspension system for a wheel of the bicycle, the suspension system including a smart fluid damper for dampening a movement of the wheel relative to the frame. The smart fluid damper includes a flow control element disposed within a cavity of the damper and configured to apply a field to a smart fluid within a fluid passage extending through the flow control element. The flow control element includes field barriers proximate the fluid passage to locally block and/or divert the field such that the field cannot pass therethrough. The field barriers are arranged to cause the field to criss-cross the fluid passage at multiple axial intervals along the fluid passage, thereby focusing the field within the fluid passage.

Abstract: A smart fluid damper includes a damper body defining a cavity with smart fluid. A piston head is disposed within the cavity and is slidingly displaceable. A flow control element is disposed within the cavity. The flow control element includes a main body having a central core, and an outer housing that surrounds the main body and is spaced apart therefrom to define a fluid passage between the main body and the outer housing. The fluid passage extends axially through the main body to permit fluid flow therethrough. The central core includes an energizable coil operable to apply a field. A plurality of field barriers are provided, each operable to locally block the field generated by the energizable coil such that the field cannot pass directly therethrough. The field barriers are configured to focus the field within the fluid passage.
