The inventor, Liu Pingqian, invented the anti-heavy bicycle. This year, a 52-year-old boy, often because of riding a bicycle, can not exercise his body, and feel upset. So the boy spent two and a half years, made these two chains in front of the bicycle. The boy rides the car to the square, use his hands and feet to move forward, fast riding. The girl next door, looking at the boy riding so cool, also want to try, you also sit on your butt, but the hands and feet are messy, can not ride at all. Next, the boy decided to compare the speed with a normal bicycle. So he found a boy of the same age, to compare. But because the distance is too short, the two almost reached the finish line at the same time. The boy decided to upgrade the difficulty, and compare with the variable bicycle. At the beginning of the race, the variable bicycle was ahead, but not once, was overtaken by the boy. It seems that this car can not only exercise the body, speed is also a game. Famous person, Cao Yongzhen, invented the project, front and rear variable bicycle. This 52-year-old boy, because he rides a bicycle to work every day, has to climb a very long slope, two legs hurt, arms can not help. So Mr. Cao modified it himself, took more than two months, finally made a front and rear variable bicycle. The rider shakes the roller on the handlebars, through chain transmission, drive the front wheel to rotate forward. In order to verify the variable bicycle, Mr. Cao came with the reporter, the slope road at work every day, the kind reporter was still sitting in the back, put a big bucket of mineral spring water. Although he brought a big bucket of water, it did not affect the speed of the 200-meter slope, and only took 50 seconds. The girl next to him saw it, and wanted to try it. The girl rides the bicycle, and the boy also tried it. This year, the 32-year-old uncle, because he can not learn the side parking, so he spent two and a half years, finally made this rotating bicycle. The uncle made this small car, can both climb left and right, and can turn around in place. Even the side parking that he can not learn, is also holding a gun. The reporter next to him saw this, and was awakened, and felt that his car skills must be very good. The girl next to him, said that his car skills must be very good. The girl said, the girl still got in the car, and said humbly that she did not have much experience in driving. She hoped that the uncle would give her more advice. At this time, the uncle did not realize the seriousness of the matter, and said that the car he built did not require experience at all. Under the uncle's encouragement, the girl stepped on the gas pedal. The girl said, you are not humble, and you can only laugh sadly. In order to ease the embarrassment, the girl looked at the blue truck behind her, and rushed over. With the last lesson, the uncle was scared to death, and could only finish the first kill with his second shot. It was too dangerous, one second later, Xiaohong just blew up. The girl, who looked strong, did not give up, and wanted to kill her car. The uncle, who was embarrassed, could not refuse, and could only sit in the passenger seat and feel full of experience.
