Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of bicycles, and more particularly to handlebar assemblies and bicycles. [Background technology]

[0002] Bicycles play an important role in people's daily lives as an alternative to walking. The handlebar is an essential part for controlling the direction of movement of the bicycle. In a conventional bicycle, the wheel is attached to the front fork, which is fixed to the stem, and the handlebar is fixed to the stem, thereby controlling the swing direction of the wheel on the front fork.

[0003] However, conventional bicycles have large handlebars in the left-right direction, i.e., the dimension of the handlebars in the width direction of the bicycle is large, so the handlebars take up a lot of space when parked. When many bicycles are parked in a given parking area, the ends of the handlebars protrude, making them prone to interfering with or scratching other vehicles nearby. As a result, the upper limit of the number of bicycles that can be parked in a given parking area is limited, and parking and retrieving vehicles becomes difficult, resulting in a poor user experience when using bicycles.

[0004] The above information disclosed in the Background of the present application is intended to provide an understanding of the background of the concept of the present application and may include information that is not prior art. Summary of the Invention [Problem to be solved by the invention]

[0005] In light of this, there is a need to provide a handlebar assembly and a bicycle that solves the above problems. [Means for solving the problem]

[0006] a stem having a restricting hole drilled on its circumferential side; a handlebar including a grip and a support tube fixed to the grip, one of the support tube and the stem being rotatably fitted to the other, and a positioning hole being formed in an outer circumferential surface of the support tube; and a limiting structure including a limiting member movably connected to the handlebar, the limiting member being movable between an unlocked position and a locked position relative to the handlebar, wherein in the locked position at least a portion of the limiting member is inserted into both the positioning hole and the limiting hole to lock the handlebar and the stem, and in the unlocked position the limiting member is disengaged from the limiting hole and the positioning hole to allow the handlebar to rotate relative to the stem.

[0007] The handlebar assembly described above has at least the following beneficial effects: The stem is fixed to the front fork of the bicycle and can control the direction of travel of the wheel on the front fork. When riding a bicycle equipped with the handlebar assembly, the handlebars can be rotated relative to the stem in the unlocked position. At this time, the handlebars can be rotated as a whole to a position approximately perpendicular to the wheel on the front fork, i.e., to a position approximately perpendicular to the frame, and the limiting structure can then be moved to the locked position to fix the handlebars and stem relative to each other. At this time, the handlebars can drive the stem to rotate together. This is found to be more in line with the user's riding habits. The user can face the handlebars directly and place both hands more naturally on the handlebars in front of their bodies. When a bicycle equipped with the handlebar assembly is to be parked in a designated bicycle parking area where there are many bicycles and the spacing between them is narrow, a bicycle using the handlebar assembly of the present application has the following advantages. The restricting member can be moved to the unlocked position, in which case the handlebars can be rotated relative to the stem, allowing the handlebars to be rotated to a position that is approximately parallel to the frame, i.e., the handlebars are brought closer to the vehicle body.Furthermore, since there is no need to rotate the front wheel, the front wheel can also maintain a position that is approximately parallel to the frame, thereby reducing the dimension of the handlebars in the width direction of the vehicle body and the dimension of the vehicle body in the width direction occupied by the slanted wheel.This makes it easier to park and take out the bicycle in a limited space, and also reduces interference and scratches with other vehicles nearby, minimizing the risk of damage to the bicycle.

[0008] In one embodiment, the restricting hole includes a first restricting hole and a second restricting hole, the first restricting hole and the second restricting hole being spaced apart along the circumferential direction of the stem, and the locking position includes a first locking position and a second locking position. In the first locking position, the positioning hole is aligned with the first restricting hole, and the restricting member is inserted into the positioning hole and the first restricting hole. In the second locking position, the positioning hole is aligned with the second restricting hole, and the restricting member is inserted into the positioning hole and the second restricting hole. For example, when riding a bicycle equipped with the handlebar assembly, the handlebar can rotate relative to the stem in the unlocked position. At this time, the handlebar can be rotated to a position where the handlebar as a whole is approximately perpendicular to the wheel of the front fork, i.e., the handlebar is approximately perpendicular to the frame, and then the restricting structure can be moved to the locked position to fix the handlebar and the stem relative to each other. At this time, the handlebar can drive the stem to rotate together. This is found to be more in line with the user's riding habits. The user can face the handlebars and place both hands more naturally on the handlebars in front of their body. Furthermore, when a bicycle equipped with this handlebar assembly is to be parked in a designated parking area where there are many bicycles and the bicycles are closely spaced apart, a bicycle using the handlebar assembly of the present application has the following advantages: Because the restricting member can be moved to the unlocked position, the handlebars can be rotated relative to the stem, allowing the handlebars to be rotated to a position approximately parallel to the frame, i.e., bringing the handlebars closer to the vehicle body. Furthermore, because the front wheel does not need to be rotated, the front wheel can also be maintained in a position approximately parallel to the frame. This reduces the size of the handlebars in the width direction of the vehicle body and also reduces the width direction dimension of the vehicle body occupied by the angled wheel. This makes it easier to park and remove the bicycle in a limited space, reduces interference with and scratches on other nearby vehicles, and minimizes the risk of damage to the bicycle.To prevent the handlebars from swinging when the bicycle is parked, the restricting structure is moved to the second locking position and the restricting member is inserted into both the positioning hole and the second restricting hole, thereby fixing the handlebars close to the vehicle body.

[0009] In one embodiment, an axial extension line of the first restricting hole and an axial extension line of the second restricting hole are provided at an angle.

[0010] In one embodiment, the axial extension line of the first restricting hole and the axial extension line of the second restricting hole form an angle of 90 degrees. It should be understood that in a more preferred embodiment, the handlebars in the first lock position are approximately perpendicular to the front wheel when riding, and the handlebars in the second lock position are approximately parallel to the vehicle body and the front wheel when parking. In other words, the handlebars in the first lock position and the handlebars in the second lock position are approximately perpendicular. To achieve this effect, in this embodiment, the axial extension line of the first restricting hole and the axial extension line of the second restricting hole form an angle of 90 degrees.

[0011] In one embodiment, the stem further includes a guide boss on its outer circumferential surface, and the support tube includes a guide slot on its outer circumferential surface. The guide boss is slidably fitted into the guide boss and abuts against the slot wall of the guide slot to limit the movement of the support tube in the stem's axial direction and the rotation angle of the support tube in the stem's circumferential direction. The guide boss is inserted into the guide slot and abuts against the slot wall of the guide slot in the stem's axial direction, thereby limiting the axial movement of the handlebar and the stem and preventing them from separating. Furthermore, because the length of the guide slot is limited, the sliding stroke of the guide boss within the guide slot is limited, thereby limiting the rotation stroke of the handlebar relative to the stem.

[0012] In one embodiment, the guide slot extends circumferentially around the stem, has a first end and a second end around the stem, and when a slot wall at the first end of the guide slot abuts against the guide boss, the positioning hole is aligned with the first limiting hole, and when a slot wall at the second end of the guide slot abuts against the guide boss, the positioning hole is aligned with the second limiting hole. The advantages of this configuration are as follows: Specifically, when the handlebar is rotated to a position approximately perpendicular to the front wheel, the guide boss may abut against the slot wall at the first end of the guide slot and the positioning hole may be aligned with the first limiting hole. At this time, the limiting structure may be inserted into the positioning hole and the first limiting hole, and the handlebar may be fixed to the stem, i.e., quickly positioned in the first locking position. Similarly, the guide boss may be configured to abut the slot wall at the second end of the guide slot and align the positioning hole with the second limiting hole when the handlebar is rotated to a state approximately parallel to the front wheel, and the limiting structure may be inserted into the positioning hole and the second limiting hole, and the handlebar is fixed to the stem, i.e., quickly positioned at the second lock position. In other words, by abutting the slot wall at the first end of the guide slot and the slot wall at the second end of the guide slot against the guide boss, a limiting effect can be achieved on the relative rotation between the handlebar and the stem, making it easier for the user to rotate the handlebar to the first lock position and the second lock position relative to the stem.

[0013] In one embodiment, the guide boss is a screw, and the guide boss is threadedly engaged with the outer circumferential surface of the stem.

[0014] In one embodiment, the limiting structure further includes a fixed sleeve fitted to the outer peripheral surface of the support tube, and a handle rotatably connected to the fixed sleeve, and the limiting member is provided on the side of the handle closer to the support tube.

[0015] In one embodiment, a relief hole is further drilled on the outer peripheral surface of the fixing sleeve, the relief hole is aligned with the positioning hole, and in the locked position, the restricting member is inserted into the restricting hole with at least a portion of the restricting member penetrating the relief hole and the positioning hole.

[0016] In one embodiment, the restricting member is a pin that penetrates the handle and is fixed to the handle.

[0017] In one embodiment, the limiting member at least partially fits into the limiting hole, and the limiting hole fits into the locating hole. In this configuration, the limiting member inserted into the locating hole is more closely fitted to the hole wall of the locating hole, thereby preventing a gap from forming between the limiting member and the hole wall of the locating hole, which would likely cause rattling. In addition, the limiting member inserted into the limiting hole is more closely fitted to the hole wall of the limiting hole, thereby preventing a gap from forming between the limiting member and the hole wall of the limiting hole, which would likely cause rattling.

[0018] In one embodiment, the restricting member is at least partially post-shaped.

[0019] In one embodiment, two grips are provided, and the two grips are located on opposite sides of the support tube.

[0020] In one embodiment, the stem is connected to a front fork of a bicycle and is used to control the direction of travel of a wheel connected to the front fork.

[0021] In one embodiment, the stem is rotatably fitted to the outer circumferential surface of the support tube, the limiting structure further includes a compression spring and a fixed sleeve fitted to the outer circumferential surface of the stem, a limiting cavity is provided in the fixed sleeve, the limiting member includes an operating portion, a connecting portion, and a limiting portion connected in sequence, the connecting portion is inserted into the limiting cavity, the compression spring is provided in the limiting cavity and fitted to the connecting portion, one end of the compression spring elastically abuts against the limiting portion, and the other end of the compression spring elastically abuts against the inner wall of the limiting cavity, the limiting portion can be inserted into the limiting hole and the positioning hole by the action of the elastic force of the compression spring, and the operating portion is located outside the limiting cavity and is operated by a user to pull the limiting portion to overcome the elastic force of the compression spring and pull it out of the limiting hole and the positioning hole.

[0022] In one embodiment, the support tube is rotatably fitted onto the outer circumferential surface of the stem, the limiting structure further includes a compression spring and a fixed sleeve fitted onto the outer circumferential surface of the support tube, a limiting cavity is provided within the fixed sleeve, the limiting member includes an operating portion, a connecting portion, and a limiting portion connected in sequence, the connecting portion is inserted into the limiting cavity, the compression spring is provided within the limiting cavity and fitted into the connecting portion, one end of the compression spring elastically abuts against the limiting portion, and the other end of the compression spring elastically abuts against the inner wall of the limiting cavity, the limiting portion can be inserted into the limiting hole and the positioning hole by the action of the elastic force of the compression spring, and the operating portion is located outside the limiting cavity and is operated by a user to pull the limiting portion to overcome the elastic force of the compression spring and pull it out of the limiting hole and the positioning hole.

[0023] The present application further provides a bicycle including a frame and a handlebar assembly according to any of the above embodiments connected to the frame.

[0024] Because the bicycle described above includes a handlebar assembly according to any one of the above embodiments, the bicycle also has at least the following beneficial effects: The stem of the handlebar assembly is fixed to the front fork of the bicycle, allowing control of the direction of travel of the wheel of the front fork. When riding a bicycle equipped with the handlebar assembly, the handlebars can rotate relative to the stem in the unlocked position. At this time, the handlebars can be rotated to a position where they are approximately perpendicular to the wheel of the front fork, i.e., to a position where the handlebars are approximately perpendicular to the frame, and then the limiting structure can be moved to the locked position to fix the handlebars and stem relative to each other. At this time, the handlebars can drive the stem to rotate together. This is found to be more in line with the user's riding habits. The user can face the handlebars and place both hands more naturally on the handlebars in front of their body. When a bicycle equipped with the handlebar assembly is to be parked in a designated bicycle parking area where there are many bicycles and the spacing between them is narrow, a bicycle using the handlebar assembly of the present application has the following advantages. The restricting member can be moved to the unlocked position, in which case the handlebars can be rotated relative to the stem, allowing the handlebars to be rotated to a position that is approximately parallel to the frame, i.e., the handlebars are brought closer to the vehicle body.Furthermore, since there is no need to rotate the front wheel, the front wheel can also maintain a position that is approximately parallel to the frame, thereby reducing the dimension of the handlebars in the width direction of the vehicle body and the dimension of the vehicle body in the width direction occupied by the slanted wheel.This makes it easier to park and take out the bicycle in a limited space, and also reduces interference and scratches with other vehicles nearby, minimizing the risk of damage to the bicycle.

[0027] In order to make the above-mentioned objects, features, and advantages of the present application clearer and easier to understand, specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, numerous details are set forth to provide a thorough understanding of the present application. However, the present application is not limited to the specific examples disclosed below, because the present application can be implemented in many ways other than those described herein, and similar modifications can be made by those skilled in the art without departing from the concept of the present application.

[0028] 1 to 6 , in some embodiments, the present application provides a handlebar assembly 10 including a stem 100, a handlebar 200, and a limiting structure 300. A limiting hole 110 is formed in the outer circumferential surface of the stem 100. The handlebar 200 includes a grip 210 and a support tube 220 fixed to the grip 210. A positioning hole 221 is formed in the outer circumferential surface of the support tube 220. Either one of the support tube 220 and the stem 100 is rotatably fitted to the other. For example, in one embodiment, the support tube 220 is rotatably fitted to the outer circumferential surface of the stem 100. Also, for example, in another embodiment, the stem 100 is rotatably fitted to the outer circumferential surface of the support tube 220. The limiting structure 300 includes a limiting member 310 movably connected to the handlebar 200, and the limiting member 310 is movable between an unlocked position and a locked position relative to the handlebar 200. 1 and 4, in the locked position, at least a portion of the restricting member 310 is inserted into both the positioning hole 221 and the positioning hole 110 to lock the handlebar 200 and the stem 100. In the unlocked position, as shown in FIG. 2, the restricting member 310 is disengaged from the restricting hole 110 and the positioning hole 221, allowing the handlebar 200 to rotate relative to the stem 100.

[0029] The handlebar assembly 10 described above has at least the following beneficial effects. The stem 100 is fixed to the front fork of a bicycle and can control the direction of travel of the wheel on the front fork. When riding a bicycle equipped with the handlebar assembly 10, as shown in FIG. 1 , the handlebar 200 can rotate relative to the stem 100 in the unlocked position. At this time, the handlebar 200 as a whole can be rotated to a state where it is approximately perpendicular to the wheel on the front fork, i.e., the handlebar 200 is approximately perpendicular to the frame, and then the limiting structure 300 can be moved to the locked position to fix the handlebar 200 and the stem 100 relative to each other. At this time, the handlebar 200 can drive the stem 100 to rotate together. This can be seen to be more in line with the user's riding habits. The user can face the handlebar 200 from the front and place both hands more naturally on the handlebar 200 in front of their body. When a bicycle equipped with the handlebar assembly 10 is to be parked in a designated parking area where there are many bicycles and the spacing between them is narrow, a bicycle using the handlebar assembly 10 of the present application has the following advantages: The restricting member 310 can be moved to the unlocked position, and in this case the handlebar 200 can be rotated relative to the stem 100, so as shown in Figure 3, the handlebar 200 can be rotated to a position approximately parallel to the frame, i.e., the handlebar 200 is brought closer to the vehicle body. Furthermore, because there is no need to rotate the front wheel, the front wheel can also maintain a position approximately parallel to the frame, which reduces the dimension of the handlebar 200 in the width direction of the vehicle body and also reduces the dimension of the width direction of the body occupied by the slanted wheel. This makes it easier to park and remove the bicycle in a limited space and also reduces interference with and scratches on other nearby vehicles, minimizing the risk of damage to the bicycle.

[0030] 6 , in some embodiments, the restricting hole 110 includes a first restricting hole 111 and a second restricting hole 112, which are spaced apart along the circumferential direction of the stem 100, and the locked positions include a first locked position and a second locked position, where in the first locked position, the positioning hole 221 is aligned with the first restricting hole 111 and the restricting member 310 is inserted into the positioning hole 221 and the first restricting hole 111, and in the second locked position, the positioning hole 221 is aligned with the second restricting hole 112 and the restricting member 310 is inserted into the positioning hole 221 and the second restricting hole 112. For example, when riding a bicycle equipped with the handlebar assembly 10, the handlebar 200 can rotate relative to the stem 100 in the unlocked position. As shown in FIG. 1 , the handlebar 200 is rotated to a position where it is generally perpendicular to the wheel of the front fork, i.e., the handlebar 200 is generally perpendicular to the frame, and then the limiting structure 300 is moved to the first locking position to relatively fix the handlebar 200 and the stem 100. At this time, the handlebar 200 can drive the stem 100 to rotate together. This is seen to be more in line with the user's riding habits. The user can face the handlebar 200 from the front and place both hands on the handlebar 200 in front of their body more naturally. Furthermore, for example, when a bicycle equipped with the handlebar assembly 10 is to be parked in a designated bicycle parking area where there are many bicycles and the spacing between them is narrow, a bicycle using the handlebar assembly 10 of the present application has the following advantages.The limiting member 310 can be moved to the unlocked position, allowing the handlebar 200 to rotate relative to the stem 100. As shown in FIG. 3, the handlebar 200 can be rotated to a position approximately parallel to the frame, i.e., the handlebar 200 is positioned closer to the vehicle body. Furthermore, since the front wheel does not need to be rotated, the front wheel can also be maintained in a position approximately parallel to the frame. This reduces the width of the handlebar 200 and the width of the vehicle body occupied by the tilted wheel. This facilitates parking and retrieval in limited spaces, reduces interference with and scratches on nearby vehicles, and minimizes the risk of damage to the bicycle. To prevent the handlebar 200 from swinging when the bicycle is parked, the limiting structure 300 is moved to the second locking position, and the limiting member 310 is inserted into both the positioning hole 221 and the second limiting hole 112, thereby fixing the handlebar 200 while positioning it closer to the vehicle body.

[0031] More specifically, as shown in FIG. 6, in some embodiments, the axial extension line of the first limiting hole 111 and the axial extension line of the second limiting hole 112 are provided at an angle.

[0032] For example, in the embodiment shown in FIG. 6 , the axial extension line of the first restricting hole 111 and the axial extension line of the second restricting hole 112 form an angle of 90 degrees. It should be understood that in a more preferred embodiment, the handlebar 200 in the first lock position is approximately perpendicular to the front wheel when riding, and the handlebar 200 in the second lock position is approximately parallel to the vehicle body and the front wheel when parking. In other words, the handlebar 200 in the first lock position and the handlebar 200 in the second lock position are approximately vertical. To achieve this effect, in this embodiment, the axial extension line of the first restricting hole 111 and the axial extension line of the second restricting hole 112 form an angle of 90 degrees.

[0033] 1, 2, 5, and 6, in some embodiments, a guide boss 120 is further provided on the outer peripheral surface of the stem 100, a guide slot 222 is formed on the outer peripheral surface of the support tube 220, the guide slot 222 is slidably fitted into the guide boss 120, and the guide boss 120 abuts against the slot wall of the guide slot 222 to limit the movement of the support tube 220 in the axial direction of the stem 100 and limit the rotation angle of the support tube 220 in the circumferential direction of the stem 100. The guide boss 120 is inserted into the guide slot 222, and the guide boss 120 abuts against the slot wall of the guide slot 222 in the axial direction of the stem 100, thereby limiting the axial movement of the handlebar 200 and the stem 100 and preventing the handlebar 200 and the stem 100 from separating. Furthermore, since the length of the guide slot 222 in the extension direction is limited, the sliding stroke of the guide boss 120 within the guide slot 222 is limited, and therefore the rotation stroke of the handlebar 200 relative to the stem 100 is also limited.

[0034] 5, in some embodiments, the guide slot 222 extends along the circumferential direction of the stem 100, has a first end 2221 and a second end 2222 in the circumferential direction of the stem 100, and when the slot wall of the first end 2221 of the guide slot 222 abuts against the guide boss 120, the positioning hole 221 is aligned with the first limiting hole 111, and when the slot wall of the second end 2222 of the guide slot 222 abuts against the guide boss 120, the positioning hole 221 is aligned with the second limiting hole 112. The advantages of this configuration are as follows. Specifically, when the handlebar 200 is rotated to a state approximately perpendicular to the front wheel, the guide boss 120 may be configured to abut against the slot wall of the first end 2221 of the guide slot 222 and the positioning hole 221 may be aligned with the first limiting hole 111, and at this time, the limiting structure 300 may be inserted into the positioning hole 221 and the first limiting hole 111, and the handlebar 200 may be fixed to the stem 100, i.e., quickly positioned at the first locking position. Similarly, when the handlebar 200 is rotated to a state approximately parallel to the front wheel, the guide boss 120 may be configured to abut against the slot wall of the second end 2222 of the guide slot 222 and the positioning hole 221 may be aligned with the second limiting hole 112, and at this time, the limiting structure 300 may be inserted into the positioning hole 221 and the second limiting hole 112, and the handlebar 200 may be fixed to the stem 100, i.e., quickly positioned at the second locking position. In other words, by abutting the slot wall of the first end 2221 of the guide slot 222 and the slot wall of the second end 2222 of the guide slot 222 against the guide boss 120, a restricting effect can be achieved on the relative rotation between the handlebar 200 and the stem 100, so that the user can more easily rotate the handlebar 200 relative to the stem 100 to the first lock position and the second lock position.

[0035] Furthermore, in some embodiments, the guide boss 120 is a screw, and the guide boss 120 is threadedly engaged with the outer circumferential surface of the stem 100 .

[0036] 2 and 4, in some embodiments, the limiting structure 300 further includes a fixing sleeve 320 fitted to the outer circumferential surface of the support tube 220, and a handle 330 rotatably connected to the fixing sleeve 320. The limiting member 310 is provided on the side of the handle 330 closer to the support tube 220.

[0037] Specifically, as shown in FIG. 2, in some embodiments, an escape hole 321 is further drilled on the outer peripheral surface of the fixing sleeve 320, and the escape hole 321 is aligned with the positioning hole 221. In the locked position, the restricting member 310 is inserted into the restricting hole 110 with at least a portion thereof penetrating the escape hole 321 and the positioning hole 221.

[0038] Specifically, as shown in FIG. 4, in some embodiments, the restricting member 310 is a pin that penetrates the handle 330 and is fixed to the handle 330 .

[0039] Specifically, in some embodiments, the limiting member 310 at least partially fits into the limiting hole 110, and the limiting hole 110 fits into the positioning hole 221. In this configuration, the limiting member 310 inserted into the positioning hole 221 comes into closer contact with the wall of the positioning hole 221, thereby preventing a gap from forming between the limiting member 310 and the wall of the positioning hole 221, which would make it easier for rattle to occur. Furthermore, the limiting member 310 inserted into the limiting hole 110 comes into closer contact with the wall of the limiting hole 110, thereby preventing a gap from forming between the limiting member 310 and the wall of the limiting hole 110, which would make it easier for rattle to occur.

[0040] Specifically, in some embodiments, the restricting member 310 is at least partially post-shaped.

[0045] The present application further provides a bicycle including a frame and a handlebar assembly 10 described in any of the above embodiments connected to the frame.

[0046] Because the bicycle described above includes the handlebar assembly 10 described in any of the above embodiments, the bicycle also has at least the following beneficial effects. The stem 100 of the handlebar assembly 10 is fixed to the front fork of the bicycle and can control the direction of travel of the wheel on the front fork. When riding a bicycle equipped with this handlebar assembly, the handlebar 200 can rotate relative to the stem 100 in the unlocked position. At this time, the handlebar 200 as a whole can be rotated to a state where it is approximately perpendicular to the wheel on the front fork, i.e., the handlebar 200 is approximately perpendicular to the frame, and then the limiting structure 300 can be moved to the locked position to fix the handlebar 200 and the stem 100 relative to each other. At this time, the handlebar 200 can drive the stem 100 to rotate together. It can be seen that this is more in line with the user's riding habits. The user can face the handlebar 200 from the front and place both hands more naturally on the handlebar 200 in front of their body. When a bicycle equipped with this handlebar assembly is to be parked in a designated parking area, but the parking area is crowded with bicycles and the spacing between them is narrow, a bicycle using the handlebar assembly 10 of the present application has the following advantages: The restricting member 310 can be moved to the unlocked position, and in this case the handlebar 200 can be rotated relative to the stem 100, so the handlebar 200 can be rotated to a position approximately parallel to the frame, i.e., the handlebar 200 is brought closer to the vehicle body, and since there is no need to rotate the front wheel, the front wheel can also maintain a position approximately parallel to the frame, which reduces the dimension of the handlebar 200 in the width direction of the vehicle body and also reduces the dimension of the width direction of the body occupied by the slanted wheel, making it easier to park and remove the bicycle in a limited space and also reduces interference with and scratches on other nearby vehicles, minimizing the risk of damage to the bicycle.
