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.
