The present invention relates to a folding bicycle comprising a plurality of folding elements which are grouped together into main elements, such as the frame (3), the handlebar (1), the front wheel (25), and the rear wheel (24), said main elements being combined to form one inseparable element.

The plurality of folding elements that are grouped together to form main elements allow the folding bicycle of the present invention to be carried in a so-called folded state or configuration in which it occupies a minimum volume. The folded configuration allows the bicycle to be easily transported or packed inside a standard backpack.

In the so-called unfolded or maximum-size configuration, the folding bicycle of the present invention can be cycled comfortably and safely like any standard size bicycle. The integrity of all of the components or elements of the folding bicycle of the present invention is maintained in both the folded and unfolded configurations, as well as when switching between the two configurations, meaning that there are no loose pieces and that all of the constituent elements are permanently attached to one another. The process for switching between the folded and unfolded configurations, or vice versa, is simple and does not require any external elements or additional tools, and can be carried out by the user alone following simple steps.

A portable Double Folding bicycle comprising a front wheel, a frame assembly and a rear wheel, the frame assembly comprises a handlebar, a front frame, a crossbar assembly, a rear frame and a saddle, the handlebar is detachably connected to the upper end of the front frame; and the crossbar assembly comprises a front crossbar, a middle crossbar and a rear crossbar, the rear end of the front crossbar is connected to the front end of the middle crossbar through a first folder, the rear end of the middle crossbar is connected to the front end of the rear crossbar through a second folder, and the saddle is detachably connected to the rear crossbar, with the inclination angle of the first folder being 58-62, and the inclination angle of the second folder being 89-94. The present invention facilitates the bicycle dragging and improves the overall usability of the bicycle.

A bicycle can include a forward frame triangle that can include a top tube, a bottom tube, a bottom bracket, a structural seat tube, a compliant seat tube, and a pair of seat stays. The top tube can have a first end connected to a head tube and a second end. The bottom tube can have a first end connected to the head tube. The bottom bracket can be connected to the bottom tube. The structural seat tube can be connected to the bottom bracket and the top tube. The compliant seat tube can extend in an upward direction from the bottom bracket to the top tube and within the structural seat tube. The compliant seat tube can be coupled to the forward frame triangle such that the compliant seat post can bend within the structural seat tube.

Disclosed herein is a symmetric bicycle. Accordingly, the symmetric bicycle may include a bicycle frame, a bicycle handle, a plurality of bicycle wheels, and a crank assembly. Further, the bicycle frame may include a seat member, a down member, a top member, and a head member. Further, the bicycle handle may be coupled to the bicycle frame. Further, the plurality of bicycle wheels may be coupled to the bicycle frame. Further, the plurality of bicycle wheels may include at least one front bicycle wheel and at least one rear bicycle wheel. Further, the crank assembly may be coupled with at least one of the at least one front bicycle wheel and the at least one rear bicycle wheel for propelling the symmetric bicycle. Further, the crank assembly may include a crank wheel symmetrically disposed along a vertical plane passing through the seat member.

A handle includes handle grips and a handle pipe including an attachment portion, a first grip portion, a second grip portion, a first bent portion between the attachment portion and the first grip portion, and a second bent portion between the attachment portion and the second grip portion. The first grip portion includes a first overlapping region overlapping a first handle grip and a first non-overlapping region not overlapping the first handle grip. The second grip portion includes a second overlapping region overlapping a second handle grip and a second non-overlapping region not overlapping the second handle grip. The first and second non-overlapping regions each include a thick portion having a thickness larger than, or equal to, a thickness of the attachment portion. The first and second overlapping regions each include a thin portion having a thickness smaller than the thickness of the thick portion.

An improved enclosed electric motorcycle has an electric motor directly driving the rear wheel with a chain or a belt. A pair of steering handles and an accelerator foot pedal enables a driver to drive the motorcycle like an automobile. The pair of the landing wheel assemblies individually has a take-up assembly to reduce their sprung weights, and has an electric motor to increase reliability. By adding a pair of anti-skid wheels, the driver can avoid many accidents. An inflatable safety belt and a pair of side airbags will protect the driver in an accident. If the battery pack explodes, it will be ejected away from the motorcycle to protect the driver. A drive-in electric engaging device enables the driver to drive the motorcycle to engage with a stationary charging station for charging its battery pack while parking.

A bicycle handlebar assembly including a stem extension and a handlebar cross member, a pair of steering bars affixed perpendicular to the handlebar cross member, and a pair of forearm supports affixed to the handlebar cross member in proximity with the steering bars. The gear shifting and brake controls are placed at the forward ends of the two steering bars. An embodiment of the invention would allow this handlebar assembly to be raised or lowered as the rider desires, to provide raised comfort position and a lowered aerodynamic position. The forearm supports and steering bars provide comfort and control to the rider not provided by typical handlebars. Alternatively the pair of steering bars could be replaced with a single closed steering bar circuit.
