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 transportation robot may comprise a base attached to a carriage. The base comprises a motor-assisted vehicle for transporting a first payload. The base automatically performs self-balancing functions during operation and rotates around a base axis of rotation. The carriage unit comprises a mechanical extension that is attached to the base for transporting a second payload that is different than the first payload. The carriage rotates around a carriage axis of rotation. The carriage includes a set of carriage connections configured to attach the carriage to the base so that the carriage axis of rotation is substantially collinear with the base axis of rotation. A carriage connection may include supplementary elements that enable the robot to operate properly in both first and second states (user is on or off the base) without requiring re-configuration of the carriage connection. The supplementary elements may include a resistance element and/or a damping element.

What is provided is a cargo bicycle apparatus and a kit for converting an existing bicycle into a cargo bicycle. The cargo bicycle apparatus comprises a cargo attachment that easily attaches and detaches from an existing bicycle to make the existing bicycle more utilitarian and functional. The cargo attachment connects with the existing bicycle in a way that prevents damage or permanent modification to the existing bicycle. Since no specialized tools or mechanical skills are required in the assembly of the cargo bicycle apparatus, the cargo attachment provides the operator with greater convenience and flexibility for converting an existing bicycle into a cargo bicycle apparatus. In addition, the cargo attachment is configured to automatically adjust to the geometry of nearly all existing bicycles without having to modify the geometry of the cargo attachment to match the geometry of a particular bicycle.

A mobility device includes a sidecar and a tilting vehicle including a two-wheeled bicycle, and may further include: an articulated link member including multiple link arms configured to link a vehicle body of the tilting vehicle and a body of the sidecar. In particular, linkage movements of the respective multiple link arms provide upward and downward movements, and leftward and rightward tiltings of the sidecar when a center of gravity of the vehicle body moves leftward and rightward.

A convertible cargo holder for a bicycle that is operable in a cargo mode and a child carry mode. The holder has a frame that is secured to the bicycle and that has a hoop. A liner is removably secured to the frame and has first and second side walls, first and second end walls, and a bottom wall. The liner has disconnecting fasteners to secure the side walls to the end walls, and disconnecting fasteners to secure the liner to the hoop. In cargo mode the side walls are secured to the end walls, and each of the walls are secured to the hoop to create a basket. In child carry mode the side walls are disconnected from the end walls and the hoop, and the side walls hang below the bottom wall. Seats are also provided.
