A foldable stroller includes a frame and wheels installed at a bottom of the frame. The frame has a folded state and an unfolded state. The frame includes a first bracket assembly, a second bracket assembly, a connecting bracket assembly and a supporting assembly. The second bracket assembly is arranged opposite to the first bracket assembly in a front-back direction. Each of two ends of the connecting bracket assembly is connected to the first bracket assembly and the second bracket assembly respectively. A connecting end of the supporting assembly is rotatably connected to the connecting bracket assembly, a sliding end of the supporting assembly is slidably connected to either the first bracket assembly and the second bracket assembly or the connecting bracket assembly.

Disclosed is a stroller propulsion apparatus, comprising a pair of elongated handles attached to a handlebar of a stroller. The elongated handles further comprise a grip and a resistance element. By using the grips, the user applies a pressure on the handles and the resistance element to move the handles in a forward direction and a rearward direction in a reciprocating motion propelling the stroller in the forward direction to allow a user to maintain an ergonomic positions while walking and exercising.

A folding handcart includes a frame assembly including: four upright rods, a bottom frame assembly, a front-rear arm assembly and a side enclosure assembly. By connecting the front-rear arm assembly to the bottom frame assembly, the front-rear arm assembly has a certain inclined angle relative to the ground, which is close to an angle of an everyday seat backrest, significantly enhancing comfort when children are riding. Meanwhile, the inclined angle of the front-rear arm assembly makes an opening length of the folding handcart greater than a bottom length, making it easier to load items and providing more storage space. When the folding handcart is folded, the front-rear arm assembly can close, thereby forming a shape similar to a suitcase, which greatly improves neatness of product storage; and the push rod can be erected to serve as a towing handle for dragging, thereby enhancing the convenience of product handling.

A foldable baby stroller includes a baby stroller main body, and the baby stroller main body includes a folding bottom plate; the baby stroller features convenient and efficient folding operation. By pressing the unlocking part of the latch, the locking of the telescopic rods can be quickly released by using the lever principle. When locking, it only needs to press the locking part to complete. During the folding process, the movement paths of the folding bottom plate and the folding side frame do not interfere with each other. The folding bottom plate realizes flipping and closing through the hinge connection piece, and the folding side frame adapts to the elevation of the middle connection piece by extracting the sleeve rod from the sleeve. The two work together smoothly. The supporting vertical frame remains fixed and moves closer with the stroller.

An apparatus configured to attached to a wheeled transport device is disclosed. The apparatus may include a first clamping mechanism and a second clamping mechanism configured to removably attach to the wheeled transport device. The apparatus may include a first push arm and a second push arm extending vertically from respective first clamping mechanism and second clamping mechanism. The apparatus may further include a horizontal bar configured to connect the first push arm and the second push arm. The apparatus may further include a first swiveling mechanism disposed between the first clamping mechanism and the first push arm and a second swiveling mechanism disposed between the second clamping mechanism and the second push arm. The first swiveling mechanism and the second swiveling mechanism may be configured to swivel the first push arm and the second push arm relative to the first clamping mechanism and the second clamping mechanism respectively.
