The invention discloses a novel rapidly foldable electric vehicle comprising a main beam, a rear wheel, a cross beam, a bracket and a forward/backward movable saddle, wherein a pin is arranged at a junction between a lower end of the bracket and the main beam, a supporting post is arranged at the lower end of the bracket, the bracket and the supporting post are rotatably arranged about the pin, an included angle of less than 180 is formed between the supporting post and the bracket, and a towing wheel is arranged at a lower end of the supporting post. When the vehicle is folded, the saddle slides forward from a rear part of the cross beam and drives the bracket and the supporting post to rotate counterclockwise about the pin, the towing wheel moves downward and backward and gradually touches the ground, and after the towing wheel touches the ground, the rear wheel leaves the ground and the saddle moves to a front part of the cross beam to complete the folding action, thus the vehicle is in a towed or flat state. When the vehicle is towed, the towing wheel is positioned at a middle-rear part of a vehicle body, and when a human body stands upright, the vehicle body tilts, its center of gravity naturally shifts backward, the vehicle body has less pressure on the human body and towing is performed with less effort. When the vehicle is folded, the saddle moves forward without moving backward and the rear space of the vehicle body can be saved. When the vehicle is folded and laid flat, the towing wheel touches the ground and the vehicle body does not tip over easily.

The teachings provided herein are generally directed to compact vehicle drive mechanisms that can be used in the design of a foldable, carry-on vehicle. The compact drive mechanisms presented herein, for example, have contributed to the advent of the compact, carry-on bicycles set-forth in the teachings which include drive-and-steering units and drive-and-chassis units.

Foldable electrical vehicles and related charging infrastructure are described. The foldable electrical vehicle generally includes three structural members (front and rear wheel-bearing structural members and a seat-bearing structural member) that are pivotally interconnected along their lengths such that they may be pivoted between a closed position wherein the three structural members are disposed roughly parallel to each other in a compact folded configuration, and an open riding configuration wherein an angular relation is formed between the structural members. The rear wheel-bearing structural member may comprise one or more foldable wheels pivotably interconnected thereto.

Disclosed is an intelligent folding bicycle with a power wheel, including a front frame assembly and a back frame assembly folded through a rotating assembly, a fixing assembly movably arranged between the front frame assembly and the back frame assembly, a front power wheel assembly movably and detachably arranged on the front frame assembly, a back wheel assembly movably arranged on the back frame assembly, a handle assembly arranged above the front frame assembly, a cushion assembly arranged on the back frame assembly, and two pedals movably and symmetrically arranged on the front frame assembly or the back frame assembly, respectively. According to the present invention, functions of detaching the power wheel and folding the bicycle are achieved.

A foldable bicycle includes a main frame, a front frame, a swingable middle frame, and a rear strut. The main frame includes a front casing, a middle pivoting member, and a rear pivoting member. The front frame is inserted into the front casing. The swingable middle frame includes an upper section, a middle section pivotally connected with the middle pivoting member, and a lower section including a guiding groove. The guiding groove includes first and second groove ends. The distance between the first groove end and the middle pivoting member is greater than that between the second groove end and the middle pivoting member. The rear strut includes a first end pivotally connected to the rear pivoting member and a second end connected to a slider. The slider is slidably received in the guiding groove and capable of being selectively moved between the first and second groove ends.

An apparatus, includes a first pair of brackets coupled to a first bicycle frame component, and one of the first pair of brackets has a radially-inwardly extending first protrusion. The apparatus includes a first gear component coupled to a second bicycle frame component, and the gear component is rotatably coupled within the first pair of brackets. The first gear component has a first set of recesses radially spaced from each other about a periphery thereof. The apparatus further includes a first clamping component engaging at least one of the first pair of brackets and selectively biasing the first protrusion into one of the first set of recesses to rotatably lock the first gear component with respect to the first pair of brackets.

Compact vehicle drive mechanisms are provided. These compact drive mechanisms, for example, have contributed to the advent of the compact, carry-on bicycles set-forth in the teachings.

Allows a convenient, simple and compact folding, without requiring to remove any of the wheels, while occupying a minimal space in its maximum folded position. The folding bicycle (1) of the invention is characterised in that: the bar (11) has two articulation points (F1, F2), where each of said articulation points (F1, F2) has its own axis of rotation (A1, A2); the folding means comprise a pair of hinged attachments (110A, 110B), integrated in the bar (11) and connected to each of the articulation points (F1, F2); and where the pair of hinged attachments (110A, 110B) are separated from each other by a distance (D) in the longitudinal sense of the bar (11), at a position opposite to and facing each other.
