The invention relates to a bike, and in particular relates to a snow bike capable of improving the running stability. The snow bike is characterized in that the distance from a rear axle yoke at the chain wheel side to a central line of the bike body is more than the distance from rear axle yoke at the side opposite to a chain wheel to the central line of the yoke; a spoke of a rear wheel at the chain wheel side is longer than that of the spoke of the rear wheel at the side opposite to the chain wheel; the central line of a rear tire surface is overlapped with the central line of the bike body; a bottom bracket of the bike body symmetrically extends toward two sides of the bike body, and a medium axle which is arranged in the bottom bracket by sleeving symmetrically extends toward the two sides of the bike body, and then the plane of the chain wheel hung between the medium axel and the rear axle is parallel to the plane of the center of the bike body, and therefore, the plane of the chain wheel can be prevented from being inclined. According to the snow bike capable of improving the running stability, the distance from the chain wheel at the chain wheel side and the tire surfaces is extended, so that the friction between the chain wheel and tires can be effectively prevented.
