[0036] The following reference Figure 1 This application describes a riding bicycle according to some embodiments.

[0037] This application provides a vehicle that can be ridden independently, such as... Figure 1 As shown, the bicycle includes a front wheel 11, a rear wheel 21, handlebars, pedals 8, and a frame. The frame includes a front fork 1, a rear fork 2, and a frame body connecting the front fork 1 and the rear fork 2. The front fork 1 is used to mount the front wheel 11, the rear fork 2 is used to mount the rear wheel 21, and the frame body is used for the handlebars and pedals 8. The frame body includes a head tube 3, a seat tube 4, and a cross tube connecting the head tube 3 and the seat tube 4. The lower end of the head tube 3 is connected to the front fork 1, the upper end of the head tube 3 is used to mount the handlebars, the seat tube 4 is used to connect the rear fork 2, and the lower end of the seat tube 4 is used to mount the pedals 8.

[0038] In a typical bicycle, the upper end of the seat tube 4 is used to mount the saddle, and the seat tube 4 is relatively long to allow the rider to sit comfortably at the saddle height. However, in this application, the upper end of the seat tube 4 is left unmounted, and the seat tube 4 is shortened to a length of 270mm-280mm. Furthermore, the upper end of the seat tube 4 is tilted towards the rear fork 2 at an angle of 18° to 25°, for example, 20°. This allows the overall structure of the frame and its geometric position in space to meet the requirements of a human riding posture, enabling the bicycle of this application to retain its riding function while adding a simulated running fitness function, thus expanding the bicycle's range of applications.

[0039] In one embodiment of this application, preferably, the horizontal tube includes an upper tube 5 and a lower tube 6. One end of the upper tube 5 is connected to the head tube 3, and the other end of the upper tube 5 is connected to the upper end of the vertical tube 4. The lower tube 6 is located below the upper tube 5, and the lower tube 6 is diagonally supported between the vertical tube 4 and the upper tube 5. That is, one end of the lower tube 6 is connected to the lower end of the vertical tube 4, and the other end of the lower tube 6 is connected to the end of the upper tube 5 away from the vertical tube 4, thereby giving the frame body good stability.

[0040] In this embodiment, preferably, the length of the top tube 5 is adjustable so that the wheelbase of the frame and the lateral distance from the bottom bracket 81 to the front axle can be adjusted according to the rider's riding posture. The axle of the front wheel 11 is the front axle, the axle of the rear wheel 21 is the rear axle, the pedal 8 is mounted on the frame body via the bottom bracket 81, and the wheelbase of the frame is the lateral distance from the front axle to the rear axle.

[0041] Regarding the adjustable-length upper tube 5, in this embodiment, preferably, the upper tube 5 includes an inner tube 52 and an outer tube 51. The outer tube 51 is sleeved on the outside of the inner tube 52, and one end of the outer tube 51 is connected to the riser 4. One end of the inner tube 52 extends from the end of the outer tube 51 away from the riser 4 and is connected to the head tube 3. The outer tube 51 and the inner tube 52 can slide relative to each other, allowing the inner tube 52 to retract into or extend out of the outer tube 51, thereby adjusting the length of the upper tube 5. This adjustment of the upper tube 5 length allows for adjustment of the wheelbase of the frame and the distance from the bottom axle 81 to the front axle.

[0042] It should be noted that the upper pipe 5 is connected to the lower pipe 6 through the outer pipe 51.

[0043] In this embodiment, preferably, the outer tube 51 has a first positioning hole, and the inner tube 52 has a second positioning hole. Moving the inner tube 52 allows the second positioning hole to align with the first positioning hole, enabling the insertion of fasteners and thus fixing the outer tube 51 and the inner tube 52, locking the upper tube 5 at a predetermined length position. The number of second positioning holes is multiple, and these holes are spaced apart along the length of the inner tube 52. By aligning different second positioning holes with the first positioning hole and inserting fasteners, the upper tube 5 can be locked at different length positions.

[0044] In this embodiment, two first positioning holes can also be provided on the outer tube 51. After each adjustment of the length of the upper tube 5, the two first positioning holes can correspond one-to-one with the two second positioning holes, so that the relative position between the inner tube 52 and the outer tube 51 can be fixed by two fasteners to ensure the stability of the connection.

[0045] In one embodiment of this application, preferably, the front fork 1 includes two front fork tubes spaced side by side, each with a mounting portion at its lower end, and the front wheel 11 is located between the two front fork tubes, with the two ends of the axle of the front wheel 11 (the aforementioned front axle) correspondingly mounted to the mounting portions of the two front fork tubes.

[0046] In this embodiment, the lower ends of both front fork tubes 1 are provided with multiple mounting portions spaced apart front to back, and the multiple mounting portions of the two front fork tubes 1 are arranged opposite each other in a one-to-one correspondence. The front-back arrangement here is consistent with the front-back coordinate system of the frame body, that is, the side facing the front wheel 11 is the front side of the frame body, and the side facing the rear wheel 21 is the rear side of the frame body. This allows the axle of the front wheel 11 to be mounted at any two opposite mounting portions, and thus the mounting angle of the front fork 1 can be appropriately adjusted according to the rider's riding posture.

[0047] Preferably, the mounting angle of the fork 1, that is, the tilt angle between the fork 1 and the horizontal direction, is 69°±5°.

[0048] In one embodiment of this application, preferably, the handlebar includes a handlebar 7 and a handlebar stem 72. The lower end of the handlebar stem 72 is connected to the upper end of the head tube 3. The handlebar 7 is provided with a handlebar connector 73, which can be tightly clamped onto the handlebar stem 72. Specifically, the handlebar connector 73 is a clamp with an opening, which can be fitted onto the handlebar stem 72. At the same time, a fastener is provided at the opening, and by tightening the fastener, the handlebar connector 73 can be clamped onto the handlebar stem 72.

[0049] In this embodiment, preferably, a height adjustment block can be fitted onto the handle riser 72 to provide support for the handle connector 73 from below, thereby improving the installation stability of the handle 7 on the handle riser 72. Simultaneously, the number of height adjustment blocks on the handle riser 72 is adjustable; the installation height of the handle connector 73 on the handle riser 72 can be adjusted by increasing or decreasing the number of height adjustment holes.

[0050] In this embodiment, preferably, the handlebar 7 is connected to the handlebar joint 73 via an angle adjustment component 71, thereby making the angle of the handlebar 7 adjustable for easy grip by the rider. The angle adjustment component 71 applied to the bicycle handlebar 7 is prior art and will not be described in detail here.

[0051] In one embodiment of this application, preferably, the pedals 8 are mounted on the frame body via a bottom bracket 81; specifically, the bottom bracket 81 is rotatably mounted on the lower end of the riser tube 4 of the frame body, and there are two pedals 8, located on the left and right sides of the frame body respectively, and connected to the bottom bracket 81 via cranks respectively. The frame body is also provided with a central motor and a gearbox. The central motor can act on the bottom bracket 81 through the gearbox, so as to drive the bottom bracket 81 to rotate by outputting torque through the central motor, thereby assisting the movement of the cranks and pedals 8 through the central motor to reduce riding resistance.

[0052] In this embodiment, preferably, a controller is also provided on the handlebars. The controller is communicatively connected to the mid-drive motor and can control the start and stop of the mid-drive motor. At the same time, a force sensor is provided on the pedal 8. The force sensor is communicatively connected to the mid-drive motor through the controller. When the mid-drive motor starts to assist riding, the force sensor can detect the force of the rider pressing the pedal 8, and the controller can control the output torque of the mid-drive motor according to the magnitude of the pressing force.

[0053] The mid-mounted motor used in bicycle bottom brackets is existing technology and will not be discussed further here.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
