[0013] Furthermore, the auxiliary rotating wheels are arranged in pairs, and each pair of auxiliary rotating wheels is symmetrically arranged on both sides of the track through a mounting axis.

[0014] By adopting the technical solution of the utility model, the beneficial effects of the utility model are as follows: the track structure is used to enhance the grip and improve the safety of snow riding. Compared with traditional two-wheeled bicycles, riding in a snowy environment is more stable and reliable, the probability of slipping is reduced, and the driving is more reliable; at the same time, a motor is set to drive the annular track to rotate to provide assistance and improve the riding speed of the bicycle; the overall structure is simple, and the assembly and use are safer and faster. The contact area between the annular track and the ground is large, which ensures the riding feel while accelerating and stabilizing the riding state; the structure can be adapted to most traditional bicycles, and the bicycle track structure can be directly installed on the rear fork of the traditional bicycle instead of the rear wheel. It has a high degree of adaptability and is quick and convenient to replace. It can be used for upgrading and improving most bicycles on the market. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The specific embodiments of the present invention are further described in conjunction with the accompanying drawings to make the present technical solution clearer and more understandable.

[0021] like Figure 1-Figure 4As shown, this embodiment discloses a bicycle track structure for snow riding, including a motor 1, a gear 2, an annular track 3, and a driven mechanism mounted on a motor fixed shaft 7. The driven mechanism includes a plurality of rotating wheels 4 and a bracket assembly 5. The upper and lower sides of the bracket assembly 5 are respectively mounted with gears 2 and rotating wheels 4. The annular track 3 is arranged around the outer sides of the driven gear 2 and rotating wheel 4. When riding, the chain of the bicycle is connected to the flywheel 10 mounted on the motor fixed shaft 7. The user steps on the pedal to drive the chain and flywheel 10 to rotate. At the same time, the motor 1 drives the gear 2 to rotate to provide assistance, driving the annular track 3 to rotate, and the annular track 3 drives the lower rotating wheel 4 to rotate, so as to realize bicycle riding.

[0022] The outer wall of the annular crawler 3 is provided with anti-skid convex patterns 31. The anti-skid convex patterns 31 of the present embodiment are arranged in double rows in a V shape.
