Abstract: A bicycle trailer latch comprises a skewer engaging surface that is desirably at least in part spherical, such as hemispherical. When engaging a bicycle skewer at the rear wheel of a bicycle, the spherical engagement surface allows more freedom of movement of the bicycle trailer relative to the skewer during towing. This enhances the trailers ability to track the movement of the bicycle. The latch can comprise a housing with a housing opening sized to receive the end portion of the bicycle wheel skewer. A stop inside the housing is pivotal to stop closed and stop open positions. In the stop closed position, the housing opening is sufficiently to block the decoupling of the latch from bicycle skewer. In the stop open position, the stop opens the housing opening sufficiently to permit passage of the end portion of the skewer through the housing opening.

Abstract: A bicycle trailer pivot assembly can comprise first and second yoke arms with respective first and second end portions and a pivot coupling the first end portion of each yoke arm to a bicycle trailer frame. The first end portions the yoke arms comprise respective first and second hinge portions that interfit and that receive a hinge pin that couples the first end portions together and to the bicycle trailer frame for pivoting about an upright axis. The first and second hinge portion comprise respective stops positioned to engage one another to limit the maximum distance to which the second end portions of the first and second yoke arms can be spread apart. The first and second hinge portions can comprise respective stops that limit both the maximum and minimum spread apart positions of the second end portions of the yoke arms.

Abstract: A bicycle skewer for supporting a wheel of a bicycle between bicycle forks on opposite sides of the supported bicycle wheel comprises a skewer body having first and second end portions and a longitudinal axis about which a supported bicycle wheel pivots. In accordance with an embodiment, a first coupler is coupled to the first end portion of the skewer body and a second coupler is coupled to the second end portion of the skewer body; the bicycle wheel and forks being positioned between the first and second couplers. In addition, each of the first and second couplers comprise exterior surfaces at least a portion of which are spherical.

Abstract: A bicycle trailer has a frame with a hitch portion that comprises first and second yoke arms with respective first end and second end portions. Skewer engagement latches can be coupled to the second end portions of the yoke arms. The skewer engagement latches can have stops that pivot between stop open and closed positions. In the stop open positions, respective end portions of a bicycle skewer can inserted into or separated from the latches. In the stop closed positions, respective end portions of the bicycle skewer, if positioned in respective latches, are retained coupled to the yoke arms by the latches. The stops are moved between open and closed positions by an actuator, such as by respective cable portions attached to the stop portions. Desirably the actuator simultaneously moves the stops between the open and closed positions. The latches can have skewer engagement surfaces that are least in part spherical.
