Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bicycles, in particular to a training device for training bicycle stunt riding and an operation method thereof. BACKGROUND

[0002] Stunt riding integrates bicycle skills, acrobatics and artistic performance, presenting visual shock through wonderful actions, meeting the pursuit of young people for extreme challenges and personal expression, and showing unique charm in commercial performances.

[0003] Front wheel fixing and rear wheel fixing are the core basic techniques of stunt riding, not only existing as independent performance actions, but also being the technical basis of advanced skills. These two balancing techniques focus on the precise control ability of the rider over the vehicle's center of gravity, which is a prerequisite for most advanced skills. Front wheel fixing requires the rider to shift the vehicle's center of gravity to the front, lift the rear wheel, and balance only with the front wheel; rear wheel fixing lifts the front wheel off the ground and relies entirely on the rear wheel to maintain balance. The development path of stunt riding techniques is usually: basic riding → front / rear wheel fixing → single wheel balance change → handlebar / seating skill → jumping / inverted skill → extreme combination action. Therefore, front and rear wheel fixing is the key bridge connecting basic skills and high-level actions, and is an indispensable transitional link in the riding skill system.

[0004] Limitations of existing stunt riding training equipment: rear wheel fixing (referred to as "rear wheel fixing") is a core technique of stunt riding, but the existing training method faces multiple challenges. 1. Many safety hazards: stable parking is required before training, but left-right balance control is difficult, the contact area between the conventional bicycle and the ground is small, and the balance point is difficult to find, which cannot provide sufficient lateral stability, making it difficult for beginners to establish the necessary basic balance before the action, increasing the psychological burden. 2. Difficulty in controlling the center of gravity: the car head pulling action relies on the transfer of the center of gravity, but there are significant risks: improper brake control causes the rear wheel to slide and causes the car to flip backward, uneven left and right hand strength causes the car to roll sideways, and excessive force can easily cause direct backward flipping. These risks increase the psychological burden of beginners, requiring the rider to handle the car head pulling and left-right balance at the same time, which is too difficult and hinders skill learning. 3. Lack of authenticity: the existing fixed training rack can practice center of gravity control, but has serious defects: the rear wheel is fixed and cannot be lifted off the ground, the complete fixing action cannot be completed; it cannot simulate the change of the fulcrum produced by the circular feature of the rear wheel in actual riding; the training experience is disconnected from actual application, affecting skill transfer. 4. Technical gap: there is no coherent transition design from basic training to advanced skills, and there is no phased training system, resulting in low learning efficiency, the training equipment cannot provide immediate feedback, and the exerciser cannot correct the action essentials.

[0005] The front-wheel stationary training also has the problems of insufficient safety, poor stability, steep learning curve and single function, making it difficult for beginners to master this key skill. These limitations highlight the importance of developing specialized, safe and progressive figure riding training equipment, especially training tools that can address left-right balance, prevent the risk of falling, simulate real motion characteristics, and allow complete technical movements to be implemented.

[0006] Invention patent CN201922014447.5 stationary bicycle training device and exercise bicycle training device aims to solve the problem that traditional stationary training bicycles cannot simulate the experience of outdoor riding. The device uses a first flexible support member and a second flexible support member to achieve lateral tilting function. When the rider shifts his weight to one side, the corresponding support member deforms to tilt the stand, simulating the natural inclination when turning. When the weight distribution returns to normal, the support member automatically returns to its original shape. The support member is designed uniquely, with each elastic leg having two contact points with the surface, forming an arc-shaped structure above the surface. The device is equipped with a pitch mechanism connected to the stand at the bottom of the bicycle, which can control the forward and backward pivoting of the stand. Forward tilting simulates the downhill riding feeling, and backward tilting simulates the uphill riding feeling. The mechanism can be automatically adjusted by the controller in combination with the training program, and the center foot assembly remains in contact with the surface during tilting, enhancing the realism of the training. However, it is only used to simulate outdoor riding and cannot be used for figure riding training.

[0007] Invention patent CN201380079902.2 bicycle trainer aims to solve the technical problems of lack of realistic riding feeling in existing bicycle trainers, inability to tilt for stationary trainers, and excessive difficulty in balancing the bicycle roller. The biasing device (2) combined with the piston (16) and the spring (11) system design solves the problem that the bicycle cannot tilt. The device allows the bicycle to rotate or pivot around the longitudinal axis, simulating the tilting motion in actual riding. The design of the rear wheel freely leaning on the roller (3a and 3b) instead of being fixedly connected through the rear axle solves the adverse effects of the rear axle connection. This design avoids the unnatural transmission of biasing force through the rear wheel, allowing the bicycle to move freely as in actual riding conditions. The support of the main frame bottom bracket by the device (17), the connection of the bicycle down tube by the rod (18) and the adapter (19) system solves the problem of excessive difficulty in balancing. This support structure provides the necessary stability while still allowing the bicycle to move naturally, reducing the training difficulty without sacrificing the realistic riding feeling.

[0008] From the above patent documents, it can be seen that there is currently no training device specifically designed for figure riding training. SUMMARY

[0009] In order to solve the above technical problems, the application provides a training device for training bicycle stunt riding, which has simple structure and can effectively train bicycle stunt riding.

[0010] The application solves the above technical problems in the following way:

[0011] The training device for training bicycle stunt riding comprises a training device body, which comprises a training device front fork, a training device main frame connected with the training device front fork, and a pedal mechanism installed on the training device main frame, and further comprises two positioning training mechanisms, i.e., a front positioning training mechanism and a rear positioning training mechanism.

[0012] The positioning training mechanism comprises a first support shaft, two wheels, and two water-drop-shaped tires. The two ends of the first support shaft are provided with a plurality of fixing holes in the circumferential direction, the wheel discs of the two wheels are provided with positioning holes corresponding to the fixing holes, fasteners are fixedly connected with the positioning holes and the fixing holes, and the two wheels are coaxially fixedly connected to the two ends of the first support shaft, respectively. The two water-drop-shaped tires are fixedly connected to the outer periphery of the hubs of the corresponding wheels, and the two water-drop-shaped tires are symmetrically arranged. The tip of the water-drop-shaped tire points away from the training device body, and the tip of the water-drop-shaped tire has a lifting angle a around the axis of the first support shaft, wherein a is 0-60°. The end of the training device front fork is fixedly connected with the first support shaft of the front positioning training mechanism, and the end of the training device main frame is fixedly connected with the first support shaft of the rear positioning training mechanism.

[0013] Further, one end of the water-drop-shaped tire is a circular arc surface, and the other end is a tip formed by two intersecting planes, the included angle of the tip is 50-70°, the tail ends of the two intersecting planes are tangent to the circular arc surface, the water-drop-shaped tire is symmetrically arranged along the center line from the tip to the center of the circular arc surface, and the diameter of the circular arc surface is 5-8 cm.

[0014] Firstly, the design has wheels on the left and right sides of the first support shaft. Compared with the traditional single-wheel design, the double-wheel layout greatly reduces the risk of vehicle rollover during training. By increasing the lateral stability, the design effectively reduces the training difficulty faced by beginners, making the process of mastering stunt riding skills more stable and gradual.

[0015] Secondly, a specially developed water droplet-shaped tire structure is adopted, one end of which is a circular arc surface with continuous curvature variation characteristics, and the other end is a sharp end structure formed by two intersecting planes, the tail ends of the two intersecting planes being tangent to the circular arc surface, ensuring smooth transition of the profile. The sharp end angle is controlled between 50°-70°, which cleverly balances the needs of positioning stability and movement flexibility. The diameter of the circular arc surface is 5-8 cm, and the design of the circular arc surface enables the contact fulcrum of the positioning training mechanism and the ground to change dynamically, thereby significantly changing the lifting height of the front or rear of the vehicle, increasing the training adaptability. When the water droplet-shaped tire sharp end is in contact with the ground, it forms a planar contact rather than the point contact of traditional circular tires, increasing the contact area and greatly improving the stability of the center of gravity during rear wheel or front wheel positioning training. This planar contact feature effectively reduces the balance difficulty in the early stage of training, making it suitable for users of all levels; at the same time, by adjusting the fixing of the positioning hole of the wheel and the different fixing holes of the first support shaft, the different angles of the lifting angle a of the water droplet-shaped tire around the axis of the first support shaft are adjusted, different support characteristics are presented under different inclination angles, and gradual training difficulty adjustment is realized.

[0016] These two designs work together to form a systematic training program improvement. The double wheel layout solves the macro stability problem, and the water droplet-shaped tire optimizes the micro contact characteristics, and the combination of the two provides a safer and more efficient technical path for bicycle figure riding training, greatly improving the accessibility and advancement space of training.

[0017] Further, the water droplet-shaped tire is made of polyamide, PVC, polyurethane or thermoplastic rubber. These materials have excellent wear resistance, ensuring that the tire maintains stable geometric shape and surface characteristics during repeated contact with the training ground surface over a long period of time. At the same time, such materials provide an ideal balance of elasticity and rigidity.

[0018] Further, the positioning training mechanism is two, respectively a front positioning training mechanism fixed to the end of the trainer front fork and a rear positioning training mechanism fixed to the end of the trainer main frame. The trainer adopts a modular design, allowing the positioning training mechanism to be installed flexibly, and users can choose three configuration modes according to training needs: only the trainer front fork is installed, only the end of the trainer main frame is installed, the other end is installed with a normal wheel, or both ends are installed. This design establishes a clear training difficulty gradient, with the front configuration focusing on direction control and front wheel positioning skills, the rear configuration strengthening the center of gravity and body stability, and the full positioning mode providing comprehensive skill training. The modular feature significantly expands the application range of the trainer, allowing beginners to start with single-end configuration and gradually advance, and professional riders to focus on specific technical weaknesses for intensive training. This design also has economic advantages, users can upgrade equipment according to budget, and improves the convenience of system maintenance.

[0019] Further, the training device for training bicycle stunt riding further comprises a gravity-relying mechanism, which comprises a relying rod and a supporting rod providing a supporting force for the relying rod.

[0020] The bottom end of the relying rod is detachably mounted on the main frame of the training device, the included angle between the relying rod and the front end of the main frame of the training device is 110-130°, the top end of the relying rod and the top end of the supporting rod are connected through a snap ring, the bottom end of the supporting rod is detachably mounted on the main frame of the training device, and the relying rod, the supporting rod and the main frame of the training device form a triangular structure. This gravity-relying mechanism provides many significant advantages. First, the triangular structure principle endows the system with excellent mechanical stability, enabling the trainee to practice various stunt skills more safely, greatly reducing the risk of tipping over, especially suitable for the initial stage. Second, the angle of 110-130° is designed based on the principle of ergonomics, providing an ideal support point position for the user, enabling the trainee to gradually feel and master the gravity transfer technology while maintaining balance. The detachable design of the gravity-relying mechanism realizes the progressive adjustment of the training difficulty. Beginners can fully utilize the mechanism to obtain stable support, and as skills improve, the support force can be adjusted, eventually completely independent of assistance, achieving independent mastery of stunt riding skills.

[0021] Further, the top end of the relying rod is provided with a relying seat for thigh relying.

[0022] Further, the training device for training bicycle stunt riding further comprises a gravity-relying mechanism, which comprises a relying rod and a supporting rod providing a supporting force for the relying rod.

[0023] The biggest advantage of the mechanism is to effectively prevent the bicycle from turning over forward or backward during the training of the trick riding. When the rider tilts the center of gravity to an angle exceeding the safety threshold, it may cause the bicycle to turn over forward or backward. At this time, the anti-rollover plate makes a large-area contact with the ground, forming a physical barrier to ensure that the bicycle will not completely overturn. This protection mechanism allows the trainer to safely explore the front and rear center of gravity limits, significantly reducing the risk of injury during high-difficulty motion practice. The trainer can focus more on mastering the technical essentials rather than worrying about safety hazards, significantly improving training efficiency. The anti-rollover mechanism and the positioning training mechanism work together, with the former providing longitudinal safety protection and the latter ensuring lateral stability, forming a comprehensive protection system. This design balances safety and training effectiveness, allowing necessary freedom of activity while providing reliable protection, especially suitable for the progressive skill training process from the basic to the advanced. The user can safely and feasibly practice high-risk actions such as standing on the bike and jumping, expanding the application scenarios and skill coverage of the training device.

[0024] Further, the training device body further comprises a handlebar, a standing handle, a vertical pipe, a head tube, a first bowl set, a second bowl set, and an adjusting buckle. The handlebar is installed at the front end of the standing handle. The upper end of the vertical pipe is inserted and clamped in the standing handle. The lower end of the vertical pipe passes through the first bowl set, the head tube, and the second bowl set in sequence and is inserted into the training device front fork with adjustable depth. The adjusting buckle locks the training device front fork and the vertical pipe. The first bowl set and the second bowl set are fixedly sleeved on both ends of the head tube.

[0025] The training device main frame comprises an inner main frame and an outer main frame. The front end of the inner main frame is fixedly connected to the outer wall of the head tube. The rear end of the inner main frame is inserted into the outer main frame with adjustable depth. First and second adjusting gears are arranged on the inner main frame and the outer main frame. It can be understood that the adjusting gears can be multiple, for example, 2 to 8, which can be adjusted for different height personnel. It can be applied to personnel with a height of 120CM-195CM. At the same time, after the gears are adjusted, screws can be inserted to fix the inner main frame and the outer main frame.

[0026] Further, the angle between the head tube and the training device main frame is 70-90°. This angle design balances the balance between control sensitivity and stability.

[0027] Further, the handlebar is a sheep horn shape.

[0028] The design makes the trainer show unique advantages in rear wheel fixed car practice: the user can smoothly rotate the sheep horn handlebar to drive the whole front system (vertical handle, vertical pipe, trainer front fork and positioning training structure) to rotate cooperatively, to create an ideal turning handle skill training environment, so that the trainer can accurately perceive the relationship between turning force and car posture, and quickly master the core essentials of turning handle skill. Meanwhile, the adjustable length of the trainer main frame and the angle of the head tube enable the trainer to adapt to users of different body types and technical levels, provide personalized training experience, and significantly improve the universality and training effect of the product. This design not only meets the professional needs of rear wheel fixed car training, but also provides a solid foundation for the whole trick riding skill system.

[0029] Further, the pedal mechanism includes two pedals and a third support shaft, the outer main frame is provided with a mounting hole, the third support shaft is installed on the outer main frame through the mounting hole, and the two pedals are respectively inserted into the two ends of the third support shaft. The pedal mechanism is designed to be firm and reliable, and the problem of pedal shaking commonly seen in traditional bicycles is eliminated.

[0030] Further, the pedal mechanism is located at the lower end of the leaning lever, achieving a relatively ideal center of gravity distribution.

[0031] Another aspect of the present application provides an operation method of a training device for training trick riding of a bicycle, comprising the following steps:

[0032] Step one: install the training device: complete the installation of the handlebar, vertical handle, vertical pipe, head tube, first bowl group, second bowl group, adjusting buckle, training device front fork, training device main frame and pedal mechanism of the training device body; the first support shaft of the front positioning training mechanism is fixedly connected to the end of the training device front fork, and the first support shaft of the rear positioning training mechanism is fixedly connected to the end of the training device main frame, thereby establishing a stable training foundation;

[0033] Step two: adjust the training device: adjust the depth of the vertical pipe inserted into the training device front fork according to the height of the user, adjust the depth of the rear end of the inner main frame inserted into the outer main frame, and adjust the angle of the lifting angle alpha formed by the tip of the water drop-shaped tire and the axis of the first support shaft according to the operation level of the user, to create suitable conditions for different difficulty training;

[0034] Step three: according to different training projects, the user pedals the pedal mechanism, moves the center of the body backward, lifts the handlebar of the bicycle, and gradually reduces the included angle between the tip of the water drop-shaped tire at the end of the training device main frame and the ground until the included angle is 0, so that the user practices rear wheel fixed car;

[0035] Or: the user pedals the pedal mechanism, moves the center of the body forward, lifts the end of the training device main frame, and gradually reduces the included angle between the tip of the water drop-shaped tire of the training device front fork and the ground until the included angle is 0, so that the user practices front wheel fixed car;

[0036] Or: on the basis of step two, install the anti-rollover mechanism on the rear positioning training mechanism fixed at the end of the main frame of the trainer, and the user pedals the pedal mechanism, moves the center of the body backward, lifts the handlebars of the bicycle, and gradually reduces the angle between the tip of the water droplet-shaped tire at the end of the main frame of the trainer and the ground until the angle is 0, and practices the rear wheel positioning skill under the protection of the anti-rollover mechanism.

[0037] Or: on the basis of step two, install the anti-rollover mechanism on the front positioning training mechanism fixed at the end of the front fork of the trainer, and the user pedals the pedal mechanism, moves the center of the body forward, lifts the end of the main frame of the trainer, and gradually reduces the angle between the tip of the water droplet-shaped tire of the front fork and the ground until the angle is 0, and practices the front wheel positioning skill under the protection of the anti-rollover mechanism.

[0039] The present application has the following advantages over the prior art:

[0040] 1. Symmetrical layout of the double-wheel positioning training mechanism: The left and right sides are designed with double wheels, which fundamentally improves the balance characteristics during training, greatly reduces the risk of rollover, and solves the inherent defects of traditional single-wheel design.

[0059] The application will be further described below in conjunction with the drawings and examples.

[0060] Example 1:

[0061] As Figure 1 shown, the training bicycle pattern riding trainer comprises a trainer body 1, the trainer body 1 comprising a trainer front fork 18, a trainer main frame 2 connected with the trainer front fork 18 and a pedal mechanism 3 installed on the trainer main frame 2, and two positioning training mechanisms 4 which are structurally identical and are respectively a front positioning training mechanism and a rear positioning training mechanism.

[0062] As Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, the positioning training mechanism 4 comprises a first support shaft 43, two wheels 41 and two water-drop-shaped tires 42; the two ends of the first support shaft 43 are circumferentially provided with a plurality of fixing holes 45, the wheel discs of the two wheels 41 are provided with positioning holes 46 corresponding to the fixing holes 45, bolts (not shown in the figure) pass through the positioning holes 46 and are fixedly connected with the fixing holes 45, and the two wheels 41 are coaxially fixedly connected at the two ends of the first support shaft 43 respectively; the two water-drop-shaped tires 42 are fixedly connected to the outer periphery of the hubs of the corresponding wheels 41, the two water-drop-shaped tires 42 are symmetrically arranged, the tips 47 of the water-drop-shaped tires 42 point away from the trainer body 1, and the tips 47 of the water-drop-shaped tires 42 have a lifting angle α around the axis of the first support shaft 43, wherein α is 0-60°; the end of the trainer front fork 18 is fixedly connected with the first support shaft 43 of the front positioning training mechanism, and the end of the trainer main frame 2 is fixedly connected with the first support shaft 43 of the rear positioning training mechanism.

[0063] In this embodiment, as Figure 7 shown, one end of the water-drop-shaped tire 42 is a circular arc surface 48, the other end is a tip 47 formed by two intersecting planes 49, the included angle of the tip 47 is 50-70°, the tail ends of the two intersecting planes 49 are tangent to the circular arc surface 48, the water-drop-shaped tire 42 is symmetrically arranged along the center line from the tip 47 to the center of the circular arc surface 48, and the diameter of the circular arc surface 48 is 5-8 cm.

[0064] First, as Figure 1 , Figure 2The design adopts a symmetrical layout of two wheels 41, which are distributed on the left and right sides of the training device body 1. This structural design fundamentally improves the balance characteristics during training. Compared with the traditional single-wheel design, the double-wheel layout significantly reduces the risk of vehicle rollover during training. By increasing lateral stability, the design effectively reduces the training difficulty faced by beginners, making the process of mastering the trick riding skills more stable and gradual.

[0065] Secondly, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 described, a specially developed water droplet-shaped tire 42 structure is adopted, one end of which is a circular arc surface 48 with continuous curvature variation characteristics, and the other end is a sharp end 47 structure formed by two intersecting planes 49, the tail ends of the two intersecting planes 49 are tangent to the circular arc surface 48, ensuring smooth transition of the profile. The included angle of the sharp end 47 is controlled between 50°-70°, which cleverly balances the positioning stability and movement flexibility requirements. The diameter of the circular arc surface 48 is 5-8 cm. The design of the circular arc surface 48 allows the contact fulcrum of the positioning training mechanism with the ground to change dynamically, thereby significantly changing the lifting height of the front or rear of the vehicle, increasing the training adaptability. When the sharp end 47 of the water droplet-shaped tire 42 is in contact with the ground, it forms a planar contact rather than the traditional point contact of a circular tire, increasing the contact area and greatly improving the stability of the center of gravity during rear wheel or front wheel positioning training. This planar contact feature effectively reduces the balance difficulty at the beginning of training, making it suitable for users of all levels; at the same time, by adjusting the fixed connection of the positioning hole 46 of the wheel 41 with the different fixed holes 45 of the first support shaft 43, the different angles of the lifting angle α of the water droplet-shaped tire 42 around the axis of the first support shaft are adjusted, different support characteristics are presented under different inclination angles, and gradual training difficulty adjustment is achieved.

[0066] In this embodiment, the water droplet-shaped tire 42 is made of polyamide. These materials have excellent wear resistance, ensuring that the tire maintains stable geometric shape and surface characteristics during long-term repeated contact with the training site surface. At the same time, such materials provide an ideal balance of elasticity and rigidity.

[0067] In this embodiment, as Figure 1 , Figure 2As shown, the positioning training mechanism 4 is 2, respectively, the front positioning training mechanism of the front fork 18 end of the fixed training device and the rear positioning training mechanism of the main frame 2 end of the fixed training device. The training device adopts modular design, allows the positioning training mechanism 4 to be installed flexibly, and the user can select three configuration modes according to the training needs: only the training device front fork is installed, only the training device main frame is installed, the other end is installed with ordinary wheels (not shown in the figure), or the front and rear positioning training mechanisms are installed. This design establishes a clear training difficulty gradient, the front configuration focuses on direction control and front wheel positioning skill training, the rear configuration strengthens the rear center of gravity and the stability of the vehicle body, and the full positioning mode provides comprehensive skill training.

The pedal mechanism 3 is designed to be firm and reliable, and the problem of pedal shaking commonly seen in traditional bicycles is eliminated.

[0069] In this embodiment, as shown in Figure 1 、 Figure 9 The training device body 1 further includes a handlebar 11, a vertical handle 12, a vertical pipe 13, a head tube 14, a first bowl set 15, a second bowl set 16 and an adjusting buckle 17, the handlebar 11 is installed at the front end of the vertical handle 12, the upper end of the vertical pipe 13 is inserted and clamped in the vertical handle 12, the lower end of the vertical pipe 13 passes through the first bowl set 15, the head tube 14 and the second bowl set 16 in turn, and is inserted into the training device front fork 18 with adjustable depth, the adjusting buckle 17 locks the training device front fork 18 and the vertical pipe 13, and the first bowl set 15 and the second bowl set 16 are fixedly sleeved on the two ends of the head tube 14.

[0070] The training device main frame 2 includes an inner main frame 21 and an outer main frame 22, the front end of the inner main frame 21 is fixedly connected to the outer wall of the head tube 14, the rear end of the inner main frame 21 is inserted into the outer main frame 22 with adjustable depth, the inner main frame 21 and the outer main frame 22 are provided with a first adjusting gear 23 and a second adjusting gear 24, and the end of the outer main frame 22 is fixedly connected to the first support shaft 43.

[0071] In this embodiment, as shown in Figure 1 The angle between the head tube 14 and the training device main frame 2 is 70-90°, which balances the balance between control sensitivity and stability.

[0072] As shown in Figure 9 The handlebar 11 is a sheep horn shape.

[0073] The design makes the trainer show unique advantages in rear wheel fixed car practice: the user can smoothly rotate the sheep horn handle 11, drive the entire front system (vertical handle 12, vertical pipe 13, trainer front fork 18 and positioning training mechanism 4) to rotate coordinately, create an ideal turning handle skill training environment, and enable the trainer to accurately perceive the relationship between turning force and body posture, quickly master the core essentials of turning handle skill. At the same time, the adjustable length of the trainer main frame 2 and the angle of the head pipe 14 enable the trainer to adapt to users of different body types and technical levels, provide personalized training experience, and significantly improve the universality and training effect of the product. This design not only meets the professional needs of rear wheel fixed car training, but also provides a solid foundation for the overall trick riding skill system.

[0074] Embodiment 2:

[0075] The main differences between this embodiment and embodiment 1 are as follows:

[0076] In this embodiment, as shown in Figure 1 , Figure 10 , the training device for training trick riding of a training bicycle further comprises a gravity leaning mechanism 5, wherein the gravity leaning mechanism 5 comprises a leaning rod 51 and a supporting rod 52 for providing supporting force to the leaning rod 51.

[0077] The bottom end of the leaning rod 51 is detachably installed on the trainer main frame 2, the included angle between the leaning rod 51 and the front end of the trainer main frame 2 is 110-130°, the top end of the leaning rod 51 and the top end of the supporting rod 52 are connected through a snap ring 54, and the bottom end of the supporting rod 52 is detachably installed on the trainer main frame 2. The leaning rod 51, the supporting rod 52 and the trainer main frame 2 form a triangular structure. This gravity leaning mechanism 5 provides many significant advantages. First, the principle of triangular structure gives the system excellent mechanical stability, enabling the trainer to practice various trick skills more safely, greatly reducing the risk of falling, especially suitable for the initial stage. Second, the angle design of 110-130° is based on the principle of ergonomics, providing an ideal support point position for the user, enabling the trainer to maintain balance while gradually feeling and mastering the gravity shift technique. The detachable design of the gravity leaning mechanism 5 realizes the progressive adjustment of training difficulty. Beginners can fully utilize the stable support provided by this mechanism, and as their skills improve, they can adjust the support force, and ultimately completely free themselves from assistance to independently master trick riding skills.

[0078] In this embodiment, as shown in Figure 10 , the top end of the leaning rod 51 is provided with a leaning seat 53 for the thigh.

[0079] In this embodiment, as shown in Figure 10 , the foot pedal mechanism 3 is located at the lower end of the leaning rod 51, achieving a relatively ideal gravity distribution.

[0080] Embodiment 3:

[0081] This embodiment is based on Embodiment 1, or Embodiment 1 and Embodiment 2 together, and adds a rollover prevention mechanism 6 that can be added to the positioning training mechanism 4 of the trainer front fork and / or the positioning training mechanism 4 of the trainer mainframe 2.

[0082] In this embodiment, as shown in Figure 1 , Figure 2 , Figure 6 , Figure 11 The training device for training bicycle stunt riding further comprises a rollover prevention mechanism 6, which comprises a rollover prevention plate 61, a first support 62, a second support 63, and a second support shaft 64. The second support shaft 64 passes through the first support shaft 43, and the two ends of the second support shaft 64 are respectively mounted on the top ends of the first support 62 and the second support 63. The bottom ends of the first support 62 and the second support 63 are respectively fixed to the rollover prevention plate 61. The rollover prevention mechanism 6 is installed on the front positioning training mechanism or the rear positioning training mechanism.

[0083] The greatest advantage of this mechanism is that it effectively prevents dangerous front or rear rollover accidents during stunt riding training. When the rider tilts the center of gravity beyond the safety threshold, it may cause a rear or front rollover. At this time, the rollover prevention plate 61 makes a large area of contact with the ground, forming a physical barrier to ensure that the bicycle will not completely overturn. This protection mechanism allows the trainer to safely explore the front and rear center of gravity limits, significantly reducing the risk of injury during high-difficulty motion practice. The trainer can focus more on mastering the technical essentials rather than worrying about safety hazards, significantly improving training efficiency. The rollover prevention mechanism 6 cooperates with the positioning training mechanism 4, with the former providing longitudinal safety protection and the latter ensuring lateral stability, together forming a comprehensive protection system. This design balances safety and training effectiveness, allowing necessary freedom of activity while providing reliable protection, especially suitable for progressive skill development from basic to advanced. Users can safely practice high-risk actions such as standing and jumping, expanding the application scenarios and skill coverage of the training device.
