A bicycle includes a frame having four bar elements, wherein the first bar element is pivotally connected to the second bar element by a first hinge, the second bar element is pivotally connected to the third bar element by a second hinge, the third bar element is pivotally connected to the fourth bar element by a third hinge and the fourth bar element is pivotally connected to the first bar element by a fourth hinge, a front axle protruding from the third bar element for mounting a front wheel, a rear axle protruding from the first bar element for mounting a rear wheel, wherein the fourth hinge is disposed rear of the rear axle, at least one handlebar attached to the third bar element.

Embodiments of the present application relate to the technical field of bicycles, and disclose a cargo bicycle. The cargo bicycle includes: a front frame component, including at least one front wheel; a middle frame component, including at least two auxiliary wheels and a steering structure; a rear frame component, including at least one rear wheel; a telescopic structure connected to the front frame component and the middle frame component, and capable of adjusting a horizontal distance between the front frame component and the middle frame component; and a folding device connected to the middle frame component and the rear frame component, and capable of adjusting a folding state. With the telescopic structure and the folding device, the cargo bicycle can not only load and transport a variety of cargoes of different volumes, but also reduce the overall size of the bicycle in some usage scenarios, improving user experience.

An apparatus includes a bicycle frame defining a bore, and a bicycle seat assembly including a post received in the bore. An indicating unit is configured to indicate a first position of the post along the bore for a first user and a second position of the post along the bore for a second user. An identification unit is configured to identify the first user and the second user. A computing device includes a processor and a memory, the memory storing instruction such that the processor is programmed to instruct the indicating unit to indicate the first position when the identification unit identifies the first user and to instruct the indicating unit to indicate the second position when the identification unit identifies the second user.

A ride-on device with multiple modes and functions is provided. The ride-on device (e.g., ride-on toy) may transition between multiple modes such as a stroller mode with a seat and a pusher handle, a tricycle mode with a seat and a set of pedals on a front wheel, and a scooter mode with handle connected to a front wheel and a base for standing connected to the front wheel and having a set of back wheels. The ride-on device may include a base having multiple portions that may rotate with respect to one another to transition between the stroller, tricycle, and/or scooter modes. The ride-on device may include a wheel assembly with wheels that may be moved between different wheel positions. In one example, the wheel assembly may be rotated with respect to the base such that the base is positioned above the wheel assembly.

The present invention relates to an electric scooter, and in particular to a foldable scooter. A foldable scooter is provided, comprising a front frame and a rear frame, wherein the front frame comprises a front fixation portion, and a first connecting frame and a second connecting frame which extend longitudinally; the front and rear ends of the first connecting frame are oppositely located above the front and rear ends of the second connecting frame; the rear frame comprises a rear fixation portion, and a third connecting frame and a fourth connecting frame which extend longitudinally; both the front end of the first connecting frame and the front end of the second connecting frame are fixed to the front fixation portion in a rotatable manner; the front end of the third connecting frame is fixed to the rear end of the first connecting frame in a rotatable manner, the third connecting frame deviating from its end is fixed to the rear end of the second connecting frame in a rotatable manner, and the rear end of the third connecting frame is connected to the rear fixation portion; and, the rear end of the fourth connecting frame is fixed to the third connecting frame or the rear fixation portion in a rotatable manner, while the rear end thereof is fixed to the first connecting frame in a rotatable manner. The present invention has the advantage that the folded scooter occupies less space and is more convenient for storage and transportation.
