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.

A trailer hitch is disclosed as it may be implemented for a specialized motor vehicle (e.g., the SLINGSHOT by Polaris, Inc.). An example trailer hitch includes a receiver member for mounting to a swing arm assembly for a rear wheel of the specialized motor vehicle. An example trailer hitch also includes a hitch member for connecting to the receiver, the hitch member configured to extend out and around the rear wheel of the specialized motor vehicle. An example trailer hitch also includes a mounting member on the hitch member to provide a mounting location for a trailer connection behind the rear wheel.

A trailer-coupling assembly is described for securing a trailer to a two-wheel vehicle. The trailer-coupling assembly is rigidly fixed to a rear-wheel frame of a two-wheel vehicle and the utility bed of a trailer. The trailer-coupling assembly is comprised of three joints that each rotate about three separate cardinal axes, permitting the trailer to navigate rough terrain without transferring rotational loading to the two-wheel vehicle. Each joint is configured to rotate at least 90 degrees in a clockwise direction and an anti-clockwise direction about a cardinal axis, providing the trailer-coupling assembly with flexibility to navigate the two-wheel vehicle and trailer over various grades of rough terrain.

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 motorcycle towing hitch 20 includes a receiver 22 to which is attached a lift system 24. The lift system 24 is operable to raise and lower a cradle 26 which receives the front wheel 30 of a motorcycle 32 to hold the front wheel captive in the cradle. The cradle 26 is hinged relative to the lift system to be rotatable about an upright axis 28, for instance, when towing the motorcycle around a corner. A restraint system 34 is provided for preventing the handlebars of the motorcycle to rotate relative to the motorcycle frame. In this manner, when the motorcycle is towed around a corner, the motorcycle frame does not tilt downwardly into the corner as would be the case if the motorcycle frame were permitted to rotate relative to the motorcycle handlebars when negotiating a corner.

A motorcycle trailer hitch leveling apparatus for leveling a motorcycle trailer hitch includes a pair of sides each having a lower section, an angled section, an upper section, an inner face, and an outer face. The inner face of the lower section of each side is a first distance apart equaling a second distance between the outer face of the upper section of each side. The first distance and the second distance substantially conform to a width of a trailer tongue. The lower section of each of the pair of sides is configured to selectively engage with the trailer tongue and the upper section of each of the pair of sides is configured to selectively engage with a standard ball coupler. A bridge piece is coupled between the upper section of each of the pair of sides.

A wheeled vehicle includes: a front portion having a central support frame, a front wheel pivotally mounted on a front end of the support frame for steering the wheeled vehicle, a first axle mounted on a rear end of the support frame, the first axle including a first pair of wheels mounted thereon, and a multi-axis pivot mounted on the central support frame adjacent the first axle, the multi-axis pivot including a receiver; a rear portion having a frame portion and a second axle on a rear end thereof. The second portion is secured on the multi-axis pivot of the front portion at a front end of the rear portion.

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 flexible towing device for single-track vehicles, comprising a towing element adapted for mounting on a first of single-track vehicles and comprising a flexible towing element and a lock attached to one of the ends of the flexible towing element, a locking mechanism assembly adapted for mounting on a second of single-track vehicles and comprising a first portion of the body comprising a half-seat, a second portion of the body comprising a half-seat, which half-seats of the first and the second portion, respectively, form a seat for detachable coupling of the lock of the towing element assembly, wherein the lock of the towing element assembly is releasable from the seat of the locking element mechanism assembly following applying a release force to the lock. A towing element assembly and a locking mechanism assembly for use in the flexible towing device for single-track vehicles.

An insulated container configured to store cold consumables is disclosed. The container has a body having a curved track wrapping around the body and upon which the body is able to be rolled. The body has an insulated wall encompassing a cavity configured to hold at least ice and consumables.
