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.

A control system includes a detection device and an electronic controller. The detection device is configured to detect passenger information related to at least one passenger of a human-powered vehicle driven by a driver of the human-powered vehicle in which the at least one passenger is different from the driver. The electronic controller is configured to control at least one component of the human-powered vehicle in accordance with the passenger information.
