Difference Between Shift and Single Speed Bikes (1)
Single means that there is only one speed, and variable means that several speeds can be changed. In fact, a variable speed car is just one more transmission, by changing the gear ratio between the front gears - generally called sprockets, and the rear gears generally called flywheels, to produce different operating modes.
The advantage of the transmission is that it can help you effectively reduce your physical exertion when you are not physically fit. For example, when you have a cold, the physical exertion should not be too large, so if you choose a lighter gear ratio when riding, it will be very easy to ride. Also, when women are in poor health, students should
Older people can use variable speed bicycles flexibly when trying to get tired. So the benefits of shifting cars are indeed too many.
The function of the bicycle shifting system is to change the speed of the vehicle by changing the cooperation of the chain and the gear discs of different front and rear sizes. The size of the front chainring and the size of the rear chainring determine how hard the bike turns the pedals. The bigger the front chainring is, the smaller the rear chainring is, and the more troublesome the pedals feel.
force. The smaller the front chainring and the larger the rear chainring, the easier it is to pedal. According to the ability of different riders, the speed of the bicycle can be adjusted by adjusting the size of the front and rear chainrings, or to cope with different road sections and road conditions.
Among the 25 parts of the bicycle frame, tires, pedals, brakes, chains, etc., the basic parts are indispensable. Among them, the frame is the skeleton of the bicycle, and the weight of people and goods it bears is the largest. According to the working characteristics of each component, it can be roughly divided into guiding system,
Drive system, brake system:
1. Guidance system: It consists of handlebars, front forks, front axles, front wheels and other components. The rider can change the direction of travel and keep the body balanced by manipulating the handlebars.
2. Drive (transmission or walking) system: it consists of pedals, central axle, sprocket, crank, chain, flywheel, rear axle, rear wheel and other components. The pedaling force of people's feet is driven by the pedals through cranks, sprockets, chains, flywheels, rear axles and other components, so that the bicycle continues to move forward.
3. Braking system: It is composed of brake parts, and the rider can operate the brake at any time to slow down and stop the running bicycle to ensure the safety of driving. In addition, for safety, beauty and practicality, accessories such as lights, brackets, stopwatches, and compasses are also installed.
