A foldable bicycle trailer has at least two main frames (1,2) disposed symmetrically about a central plane. These are connected by crossbars. The frames (1,2) stand on wheels (21,22) or on any other movable interface on its either side. The crossbars comprise a first element which is substantially flat in unfolded state, having at least two parallel foldable arms (9a, 10a) and a second element which is substantially upright in unfolded stage, also having at least two parallel foldable arms (11a, 12a). The foldable arms (9a, 10a, 11a, 12a) of each of first and second elements are connected by hinges (5, 6, 7,8) for connecting the foldable segments of each foldable arm.

The invention relates to a single pushchair that can be converted into a tandem pushchair, comprising: a rolling chassis; a main seat mounted with the ability to move in longitudinal translation with respect to the chassis between a single-occupant position and a dual-occupant position; an auxiliary seat, mounted with the ability to move in longitudinal translation with respect to the chassis between an inactive position retracted underneath the main seat in its single-occupant position, and a deployed active position outside the main seat in its dual-occupant position.

A multi-stage toy walker includes at least a handle, a base, and a configurable component that is adjustable from a folded-flat configuration to at least one of a seat-shaped configuration and a basket-shaped configuration.

According to an aspect, there is provided a vehicle system that includes a foot-deck-based vehicle and a seat accessory structure. The foot-deck-based vehicle includes a foot deck, a handle structure and a plurality of wheels. The foot deck is positioned to support—a user and includes a first handle structure receiving feature. The handle structure is detachably connectable to the first handle structure receiving feature. The seat accessory structure has a seat body and is detachably connectable to the foot deck so as to form a seat-based vehicle. The seat accessory structure has a second handle structure receiving feature thereon. The handle structure is detachably connectable to the second handle structure receiving feature, so as to be positioned for gripping by a secondary person when the secondary person is urging the seat-based vehicle to roll on the ground surface while the user is seated on the seat body.

Consumer wagons are provided for carrying seated children and/or household cargo. In some embodiments, the wagons have a footwell for children carried in the wagon to place/rest their feet, and the footwell is repositionable between use position lowered relative to the wagon base and a collapsed/storage position closer to the wagon base. And in some embodiments, the wagons have a pull-handle that can be moved between different positions and that is lockable in multiple of the different positions.
