The pulley 51 and the inertia wheel 52 are connected in a transmission connection. The magnetic resistance device 54 is located in front of the inertia wheel 52. The knob 9 drives the magnetic resistance device 54 to rotate, thereby adjusting the distance between the inertia wheel 52 and the magnetic resistance device 54, and thus adjusting the resistance of the inertia wheel 52. The speed ratio of the pulley 51 to the inertia wheel 52 is 1:7, making the user's riding inertia more comfortable.

[0029] Reference Figure 5 and Figure 6The vertical rod 16 is fitted with a bearing sleeve 19, and two bearings 20 arranged horizontally are provided inside the bearing sleeve 19. The rotating shaft 53 passes through the two bearings 20. A first axle 21 is provided between the two vertical plates 18. The first axle 21 passes through an inertia wheel 52, which can rotate around the first axle 21. The inertia wheel 52 is provided with a belt connecting part 521, and a belt 57 is connected between the pulley 51 and the belt connecting part 521. When the user pedals the two pedals 56 with both feet, the pulley 51 drives the inertia wheel 52 to rotate through the belt 57. The magnetic resistance device 54 provides resistance to the rotation of the inertia wheel 52.

[0030] Reference Figures 4 to 6 The magnetic resistance device 54 includes an arc-shaped magnet mounting plate 541 and multiple magnets 542 disposed on the rear side of the magnet mounting plate 541, with the multiple magnets 542 arranged vertically. The bottom surface of the crossbar 17 is provided with an inverted first U-shaped angle iron 22. A pulling member 543 is connected to the top of the magnet mounting plate 541, with the upper part of the pulling member 543 located inside the first U-shaped angle iron 22.

A spring 23 is provided inside the first U-shaped angle iron 22, which abuts against the first U-shaped angle iron 22 and the pulling member 543. The pull rope (not shown in the figure) passes through the spring 23, and the spring 23 provides elastic force to the pulling member 543. The top surface of the front support rod 2 is connected to a second U-shaped angle iron 24, and the bottom of the magnet mounting plate 541 is hinged to the second U-shaped angle iron 24.

[0031] Reference Figure 5 and Figure 6 The second U-shaped angle iron 24 is provided with a second shaft 25. Both ends of the second shaft 25 are provided with threaded holes 251. Both vertical parts of the second U-shaped angle iron 24 are provided with strip-shaped holes 241. The two ends of the second shaft 25 are connected to the two vertical parts of the second U-shaped angle iron 24 by bolts. The bolts pass through the strip-shaped holes 241 and are threaded into the threaded holes 251. A shaft sleeve 26 is fitted around the outer periphery of the second shaft 25. The bottom of the magnet mounting plate 541 is fixedly connected to the shaft sleeve 26. When the second shaft 25 is locked to the second U-shaped angle iron 24 by bolts, the shaft sleeve 26 can rotate around the second shaft 25. When the knob 9 is turned clockwise, the pull rope (not shown in the figure) pulls the magnet mounting plate 541 forward, thereby increasing the distance between it and the inertia wheel 52. When the knob 9 is turned counterclockwise, the pull rope (not shown in the figure) is released, causing the magnet mounting plate 541 to rotate backward, thereby decreasing the distance between it and the inertia wheel 52. The slotted hole 241 facilitates the adjustment of the position of the second shaft 25 during locking installation, thereby adjusting the bottom position of the magnet mounting plate 541.

[0032] Reference Figure 1 , Figures 4 to 6 The pedal assembly 5 also includes a cover 58. The pulley 51, inertia wheel 52, shaft 53 and magnetic resistance device 54 are all located inside the cover 58. The two ends of the shaft 53 extend outside the cover. The two cranks 55 and two foot pedals 53 are all located outside the cover 58. The knob 9 is located on the top front surface of the cover 58. Placing the knob 9 on the top front surface of the cover 58 reduces the distance between the knob 9 and the user, making it more convenient for the user to operate the knob 9.

[0033] Reference Figures 1 to 4 The top surface of the vertical rod 16 is provided with a connecting rod 27. The upper part of the connecting rod 27 extends into the bottom of the mounting rod 7 and is connected to the mounting rod 7 by multiple third screws 28. The mounting rod 7 is connected to a cup holder 29. When the multiple third screws 28 are removed, the mounting rod 7 can be separated from the connecting rod 27, and the cup holder 29 is convenient for users to place water cups or water bottles.

[0034] Reference Figure 1 and Figure 4 The rear support rod 3 is fitted with a sliding sleeve 30 on its outer periphery. The seat 6 is connected to the top surface of the sliding sleeve 30. One side of the rear support rod 3 has multiple pin holes 31 arranged front to back. One side of the sliding sleeve 30 has a plum blossom elastic pin 32. The end of the plum blossom elastic pin 32 is inserted into the pin hole 31. When the position of the seat 6 needs to be adjusted forward or backward, the plum blossom elastic pin 32 is pulled, so that the end of the plum blossom elastic pin 32 disengages from the original pin hole 31. At this time, the sliding sleeve 30 can slide on the rear support rod 3, thereby adjusting the position of the seat 6. When the seat 6 is adjusted to the desired position, the plum blossom elastic pin 32 is released, so that the end of the plum blossom elastic pin 32 is inserted into the new pin hole 31.

[0035] Reference Figures 1 to 6 The design principle of this utility model is as follows: First, the seat 6 and the foot pedal assembly 5 are directly installed on the inclined bracket 1, so that the supporting part of the seat 6 and the foot pedal assembly 5 tilt together, that is, the supporting part of the seat 6 and the foot pedal assembly 5 are both at the same angle to the ground. This design can realize the collinear movement of the joints, which is more in line with the original ergonomic movement, making it easier for the user to step on. Second, the bracket 1 can be divided into a front support rod 2 and a rear support rod 3. After the front support rod 2 and the rear support rod 3 are disassembled, the front support rod 2 and the foot pedal assembly 5 can be used as one part, and the rear support rod 3 and the seat 6 can be used as one part. Finally, the mounting rod 7 can be disassembled and used as one part with the armrest 8. In this way, the lazy bike is packaged in three parts when it leaves the factory or is stored, which can further reduce the packaging volume. Of course, when the sliding sleeve 30 slides forward and disengages from the rear support rod 3, the seat 6 can also be removed from the rear support rod 3. Finally, the seat 6 is directly mounted on the bracket 1, eliminating the need for the supporting rods in the prior art, which reduces the number of parts and further saves production costs.

[0036] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
