The invention discloses a rapid and labor-saving manual pedaling type intelligent bicycle. The rapid and labor-saving manual pedaling type intelligent bicycle is characterized in that two oval rails are mounted on a big frame at two sides of a central shaft of the intelligent bicycle; a rotary crank of the intelligent bicycle is made into a main crank and a retractable crank; the retractable crankis provided with a pedal plate; the pedal plate comprises a pedal plate body and a central shaft assembly which is inserted into the pedal plate body; the central shaft assembly comprises a central shaft, a first shaft sleeve, a ball bearing, a second shaft sleeve and a fixed ring; a shaft shoulder is arranged at the left end of the central shaft; the first shaft sleeve, the ball bearing, the second shaft sleeve and the fixed ring sleeve the central shaft in sequence from right to left; the fixed ring abuts against the shaft shoulder; a third shaft sleeve sleeves the right end of the centralshaft; a step hole with a big right part and a small left part is formed in the fixed ring; an inner thread which is adaptive to a left end outer thread of the pedal plate body is arranged at a large-diameter end of the fixed ring.
Description
technical field [0001] The invention belongs to the technical field of smart bicycles, in particular to a fast and labor-saving human-powered pedal smart bicycle. Background technique [0002] At present, the smart bicycles with human pedals have been quite perfect after nearly a hundred years of rapid development, especially in terms of weight. Many new materials are used in this field, which has brought many changes in the field of smart bicycles. Due to the weight of smart bicycles The speed of riding is also increased accordingly, but the development of smart bicycles is still a very slow means of transportation for most cyclists so far, and it is difficult to meet the needs of cyclists. The main reason for this is that it There is a problem with the driving structure of the electric bicycle, so that its speed cannot be improved. The physical capacity of an adult can reach 0.5-1.5 kilowatts, while the power of an electric smart bicycle is 250-300 watts, and the speed of ...
