Abstract

The invention discloses a gravity-driven chainless folding-free exercise bicycle with bicycle frame levers, which is characterized in that a front wheel axle is used as a fulcrum to form a front lever with an arc-shaped front beam frame and a steering rod; a back wheel axle is used as a fulcrum to form a back lever with a triangular back wheel fork frame and an adjustable bicycle seat tube; a bicycle head handle and a backrest bicycle seat act as main moving points of the front and back levers; a middle bearing frame and a middle axle act as concentric lifting driving points of the front and back levers; and the middle bearing frame and the middle axle rotate relatively; driving force is transmitted by a sector gear and a flywheel. The gravity-driven chainless folding-free exercise bicycle has the advantages that the bicycle frame is utilized to be manufactured into a labor-saving front-back level telescopic driving device, so the structure is simplified, materials are saved, the weight is lightened, the volume is reduced, the production is easy and the cost is lowed; since the gravity-driven chainless folding-free exercise bicycle self has an telescopic function, a complex structure and troublesome folding procedures of a folding bicycle are saved, so the gravity-driven chainless folding-free exercise bicycle is a small folding-free bicycle; and when the gravity-driven chainless folding-free exercise bicycle is ridden, hand-foot-buttock three-point whole-body synchronous coordinated movement is conducted, so a good exercise effect is achieved, labor is saved, handiness and interestingness are realized, the cost is low, and thus the practical value is high.

Description

Technical field: [0001] The invention relates to an exercise bicycle, in general, it is a frame lever gravity-driven exercise bicycle without a chain and without folding. Background technique: [0002] The various exercise bikes currently on the technical market are relatively complex, adding bulk and weight. In addition, various folding bicycles are troublesome to fold, and take up space if they are not folded. Invention content: [0003] In order to overcome the shortcomings of existing bicycles, the present invention discloses a frame lever gravity-driven exercise bicycle without chains and without folding. It uses the frame itself to make a labor-saving lever drive device. The structure is very simple, and it not only has the advantages of reliability and flexibility of traditional bicycles , also has the advantages of safety, labor saving, fitness, small size, no chain, no folding, etc. [0004] The technical scheme of the present invention is composed of arc-shaped...
