A foldable baby stroller movable between unfolded and folded states. The stroller includes a frame, a front wheel assembly on a front portion of the frame including a front wheel, a rear wheel assembly on a rear portion of the frame including two rear wheels, and a seat assembly on an upper portion of the frame. The frame includes a head tube; at least one beam having a first end pivotally connected to the head tube; at least one joint, to which a second end of the beam is pivotally connected; and at least two rear fork rods having a first end pivotally connected to the joint and a second end connected to the rear wheel assembly. Parts of the foldable baby stroller do not need to be detached during folding, thereby implementing one-click folding, and making the operation more convenient and efficient.

Disclosed is a stroller with detachable auxiliary power structure, which includes a stroller body, a power control module, and a battery unit. The stroller body includes a front wheel member, a rear wheel member, a left folding member, and a right folding member. Front ends and rear ends of the right and left folding frames are pivotally connected to the front wheel member and the rear wheel member, respectively. The power control module is mounted to a bottom of the rear wheel member and includes a drive motor that outputs a rotational speed and a torque, a gear box, and a power output shaft that has one end connected to the gear box and an opposite end connected to the rear right wheel or the rear left wheel. The battery unit is connected to the drive motor to serve as a power source.

A pushcart includes a steering unit, a main wheel, a dolly portion, an auxiliary wheel, a connecting unit, a slope angle sensor, a gyrosensor, and a case. On one end of the steering unit, there is provided a cylinder-shaped hinge unit that is supported in a rotatable manner at the other end of the connecting unit on the opposite side to the main wheels, and a holding portion is provided on the other end of the steering unit. A controller performs inverted pendulum control in which the main wheels are rotated based on the detection results of the gyrosensor and the slope angle sensor.

A tricycle is provided having a front frame assembly, a rear frame assembly pivotally connected to the front frame assembly, and a release assembly connected to both the front frame assembly and the rear frame assembly to secure the rear frame assembly to the front frame assembly in a use position and alternately in a storage position. The release assembly is moveable to allow for transitioning the rear frame assembly to the storage position from the use position. A foot rest is connected to the tricycle and is also moveable between a use position and a storage position. The tricycle also has a restraint hoop and a canopy, and quick release mechanisms to removably secure the restraint hoop and the canopy to the tricycle.

A foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.

A ridable kart can have a body that supports a front wheel and movable rear wheels. The kart can include a motor that supports and drives the rear wheels. The motor and rear wheels are configured to tilt and rotate relative to the body of the kart. The body of the kart includes a concave space in which the front and rear wheels are positioned so that they are at least partially concealed by the body when viewed from the side of the kart.

A stroller, comprising: a support frame including a handle coupled through a pivot mechanism to a front fork attached to a front wheel, a pair of struts rotatably coupled to the pivot mechanism at one end and rotatably coupled to a pair of rear wheels at another end; wherein rotation of the handle to turn the stroller causes the front wheel and the pair of rear wheels to camber in a direction of rotation of the handle.

A vertically-movable, transmission-friendly, and controllable stroller includes a front wheel component, rear wheel component, frame, and rail component. The front wheel component includes a front wheel hanger, front lateral right and left wheels mounted on the bottom of the front wheel hanger. The rear wheel component includes a rear wheel hanger, rear lateral right and left wheels mounted on the bottom of the rear wheel hanger. The frame includes front, rear, right and left lateral subframes. The front lateral subframe has a bottom pivotally connected to the front wheel component. The rear lateral subframe has a bottom pivotally connected to the rear wheel component. The rail component includes front and rear right rails disposed on front and rear right lateral upright tubes respectively, allowing left and right ends of a right lateral top tube to be vertically slidingly connect between the front and rear right lateral upright tubes.

A laterally collapsible, user-pushed, four-wheeled rollator, stroller or the like has swiveling front wheels for steering, each mounted in a fork with a vertical post, with a toothed pulley fixed thereto, rotatable in a bearing housing fixed at the front end of right and left side frames. The two swiveling front wheels can swivel to any steering angle but always in unison with each other by virtue of a flexible toothed synchronous belt extending between the toothed pulleys. The interior of each bearing housing closely surrounds each toothed pulley and the belt, preventing any disengagement of the belt from either toothed pulley even when the belt becomes slack when the left and right side frames are folded towards each other. A synchronous chain with sprockets can also be used. Tether means pull the belt/chain rearwardly to a protected position during folding.

A motorized, self-propelled stroller that is controllable via a remote control unit. The motorized stroller has a motor, a power source, and a drive shaft that is operably connected to one of the stroller's axles to drive the rotation thereof. A wireless transceiver relays signals sent from the remote control unit to the motor to control the action of the motor. The motor is adapted to drive the rotation of the axle to which it is operably connected in both clockwise and counterclockwise directions, with varying speeds. Reflectors extend along the lateral sides of the stroller frame and lights are disposed on the front portion of the frame, making the stroller more visible during low-light conditions and thus safer to operate. The motorized stroller further includes a motorized assembly that is adapted to fold and unfold the stroller frame in response to input from the remote control unit.
