Extended data
The ratio of the number of teeth of the toothed plate to the flywheel of an ordinary bicycle is fixed (that is, the number of revolutions of the wheel is fixed after pedaling for one cycle). Variable-speed bicycles have adjustable transmission ratio, which can be adjusted to make riding more labor-saving when encountering uphill or uneven sections (for example, when applied to mountain bikes, adjust the current gear to the minimum gear and the rear flywheel tower to a larger gear, so that you can climb steep slopes); If the road section is very flat or encounters a downhill slope and wants to have a fast speed, you can reverse the tooth ratio just mentioned;
Pedals can go a long way, but ordinary cars can only achieve higher speed by increasing the frequency of pedals. At a certain high frequency, it is difficult for the legs to persist, and it is easy to take off the feet (the feet slip off the pedals), which is very dangerous. Therefore, the general racing car is often equipped with a matching speed change system according to the specific terrain needs, so that riding can adapt well to various lots.
