The invention discloses a leisure bicycle and wheels thereof. The wheels comprise circular ring shape wheel rims, wheel hubs and a plurality of spokes connecting the wheel rims and the wheel hubs, wherein the eccentric distance between the centers of the wheel rims and the axes of the wheel hubs is 60-90mm. In the scheme, the spokes are rectangular tube section bars, the number of the spokes is four, and the outer end points of the spokes are the four four-fold points of carriage wheels.In the invention, the design of the wheels of the leisure bicycle is different from the original design, aneccentric distance of 60-90mm is arranged between the centers of the wheel rims and the axes of the wheel hubs, and the technical bias that the centers of the wheel rims and the axes of the wheel hubs of the wheels of the original bicycle must be overlapped is overcome. When the wheels rotate a circle, the wheels can generate the fluctuation of 120-180mm, so that the body gravity center of a driver fluctuates up and down so as to generate a fluctuation feel.On one hand, the fluctuation feel meets the mentality of the driver for pursuing novelty. On the other hand, the efficiencies of exerciseand body building can be enhanced.
