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.

A chemo mobile cart system for connecting a child transport vehicle to a mobile IV post assembly includes a quick-connect linkage having a platform and a quick-connect arm connectable to the mobile IV post assembly. The platform is releasably connected to the child transport vehicle, and a battery is disposed on the platform together with an inverter electrically connected to the battery. An electrical generator is electrically connected to the battery and disposed on or adjacent to the platform. The electrical generator is mechanically connected to the child transport vehicle and electrically connected to the battery to recharge the battery as the child transport vehicle moves across a support surface.

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.
