When the wheel distance between the 2 auxiliary wheels 14 is to be adjusted, the control rotating ring in the rotation control device is rotated, at this time, the control wire 21 pulls the third linkage rod, so that the first gear 601 is in contact with the rear wheel 23, then the rotating handle 1004 is rotated, the limiting device 10 is in contact with the middle support plate 103 in the first support 1, at this time, the limiting device 10 plays a role in limiting the rear wheel 23 from being hurt by the rear wheel tyre and being difficult to rotate after the first gear 601 is in excessive contact with the rear wheel 23, then the rear wheel 23 is rotated clockwise or counterclockwise by pushing the bicycle, at this time, the first gear 601 also drives the second linkage rod 7 through the second gear 703, the 2 guiding devices 8 on the second linkage rod 7 also move on the second linkage rod 7 in the opposite moving direction, at this time, the guiding devices 8 also drive the auxiliary wheels 14 to slide, so as to achieve the function of conveniently adjusting the wheel distance of the auxiliary wheels 14, through the function of the control device 20, the control swivel 2002 can also be rotated during riding to reduce the distance between the 2 auxiliary wheels 14, thereby more quickly helping a rider to master the riding balance; when the control device is released, the guide device 8 is pushed backwards due to the elastic force of the second spring 19, and the 2 second sliders 5 slide backwards, so that the first gear 601 in the first linkage rod 6 is closely separated from the rear wheel 23, and the track of the auxiliary wheel 14 cannot be adjusted even if the rear wheel 23 rotates.
When riding a passerby and riding, adjust the distance between 2 auxiliary wheel 14, thereby make and ride the passerby and can not fall down at the in-process of riding, ride passerby and can adjust the distance between 2 auxiliary wheel 14 according to the condition of oneself at the in-process of study bicycle, through continuous riding, slowly adjust 2 auxiliary wheel 14's distance down, thereby make and ride passerby's ability of mastering balance and slowly promote, adjust to zero the messenger when can with the distance between 2 auxiliary wheel 14, ride passerby and ride and can not fall down, it has learned the two-wheel bicycle of riding to show to ride passerby, accessible this moment adjusts first screw rod 11 in second support 2, make second support 2 rise, two auxiliary wheel 14 have liftoff this moment, ride passerby just can slowly go to adapt to the two-wheel bicycle of riding.
From the above adjusting functions, the rider can learn to master the balance to reach the best state, and the rider can learn to ride the two-wheel bicycle more quickly.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the inventive concept of the present invention, and all such changes and modifications are within the scope of the present invention.
