Bike gearing is one of the most amazing innovations in all of cycling. The right gears make it relatively easy to go uphill, and using the right gears in a sprint will give us a gutsy sprint.
The working principle of bicycle gears is: the large gear with a small gear (the outer gear of the freewheel), and a one-way rotation control reed in the freewheel. When the small gear turns backward, the reed makes a bouncing motion, and the axle is separated from the freewheel; when the small gear turns forward, the reed does not move, and the axle and freewheel come together, so the wheel can turn and go forward.
Bicycle is also known as a pedal car or bicycle, usually two-wheeled small land vehicle, can be used as an environmentally friendly means of transportation for walking, travel, more and more people will bike as fitness equipment for cycling exercise, bicycle outings. Cycling itself is also a competitive sport, with road cycling, mountain biking, track cycling, and stunt cycling competitions.
When we want to ride very fast, we usually choose to have a large gear in front and a small gear at the back, at this time the riding speed can reach very fast, but such a large gear drives the state of the small gear, we will consume more physical strength when riding. When we ride on sloping terrain, at this time we should use the combination of small gears driving large gears, that is, the front choose the smallest gear, the back choose the largest gear, this series of operations is needed to achieve through our transmission. In this case, the speed will be reduced, but it will allow you to climb the hill very easily.
