Is the giant variable-speed bicycle really faster than the ordinary bicycle? Is it easy to ride? Is the coupling easy to break?

Did you see the question from the landlord upstairs? Hello, landlord, since it's all variable speed, it doesn't matter who is faster than who. Because the speed is affected by many factors, such as front-rear ratio, tire tread, rim size, road surface, air resistance and so on. It is true that some people say that it is "faster" to ride a car with the same price, because its workmanship is better than that of ordinary cars, the steel and aluminum parts used are relatively hard, and most of the tires are brand new. It won't waste too much energy. So the speed depends at least on the ratio of front and rear teeth. As long as the front is big and the back is small, the pedal will be fast, but it will be laborious. So whether it is a giant or not, it can reach high speed. Giant is relatively easy to ride among bicycles of the same price, so it should be given priority when buying a car. Chain can't be said to be good or bad, because it is a consumable. Many giant 24-speed cars use Shimano IG565438+. More than 30 yuan, riding on ordinary roads is no problem, and dirt roads in rural areas are also ok. Be careful when crossing the road, the chain is not strong enough. In addition, if you disassemble the chain at will, the chain will collapse, because the chain is riveted between the sections. If the chain cutter is not correctly jacked when it is installed, the chain will be unevenly stressed and easily broken when riding. So you should take care of it, wipe it frequently, and don't disassemble it.
