An aerodynamic front fork assembly for a bicycle may include an elongated crown portion extending from a steerer tube to a distal end behind a front wheel, with one or more fork blades projecting in a generally forward direction from the distal end of the crown portion to engage the front wheel. The crown portion may substantially fill the gap between the front wheel and the down tube of the bicycle, thereby collectively forming an airfoil with the front wheel and the down tube.

A motorized vehicle including: a front fork; a steering shaft able to rotate inside a steering column; at least one fork crown coupled to the steering shaft and to the front fork; and at least one electronic component intended to collect and/or transmit data relating to the operation of the motorised vehicle. The fork crown has a body in which there is formed a cavity closed by a cover and an electronic board housed in the cavity and able to centralize and/or process the data supplied by the at least one electronic component.

A pivot assembly for a cycle linkage suspension is provided that includes first and second members and a pivot. The first and second members include lateral openings extending therethrough and the pivot includes a rod portion that is configured to be disposed within the lateral openings to pivotably couple the first and second members together. The rod portion further includes an opening that extends through an intermediate portion thereof. The pivot assembly can further include a pin configured to be removably inserted at least partially into the opening in the rod portion to thereby restrict lateral movement of the rod portion within the first and second members.

A power steering system for a motorcycle, such as a motorcycle trike. The power steering system includes a piston having a piston rod disposed within a cylinder. A distal end of the piston rod is pivotably coupled to a fork tube of a motorcycle fork. A power source drives the piston rod away from the cylinder and retracts the piston rod within the cylinder. A control switch controls the piston between a neutral position, a first turn position, and a second turn position. The neutral position includes the piston rod partially extended from the cylinder. The first turn position includes the piston rod extending further from the cylinder than the neutral position. The second turn position includes the piston rod retracted further within the cylinder than the neutral position.

A fastening system for attaching a component to the monocoque of a motorcycle. The fastening system promotes a plurality of riding configurations for the motorcycle. The fastening system includes an assembly of a track and a movable foot piece. The movable foot piece slides along and is locked in the track to secure the component to the track according to a desired riding configuration of the motorcycle. When the component is the headstock, the fastening system allows for a change in the rake angle.
