1. The working principle of the Bicycle code watch

The principle of the bicycle sheet is that the sensor captures the information brought by the inductive magnet when the car ring rotates, transmits it to the gauge through the sensing line, and the host code table is calculated to calculate the speed, mileage and other information after this process.

Popularly speaking, there is a magnet -like thing on the front wheels. There is a sensor on the front fork. The wheels turn around, and the magnet passes through the sensor once.In the wheel parameters, the code watch has calculated the speed and the journey.To put it simply, the airflow formed during the cycling process to generate induction of the wind hole of the code watch, thereby measuring the speed.

2. What is the reason for the Bicycle code watch

The bicycle codes are not allowed

1. The code table generally has only two keys. The "SET key" in the back is the setting key.Hold down the "SET key" behind the code watch for more than 2 seconds, and enter the setting mode after the screen displays "Set Open".

2. The screen displays "SIZE 2155", where the wheel value is set.Press "Big Key", the screen display "Unit Kmh", that is, the display value is "km/h".

3. Press "Big Key", the screen shows "Dist 0", which is the total mileage.Press "Big Key", the screen displays "time 00:02", that is, time.

4. Press "Big Key", the screen display "Scan OFF", that is, the scroll display mode is turned off.

5. Then go back to the "Time" interface, press the "SET key", the numbers flickered, and set the numbers according to the "Big Key".

6. After the time is adjusted, press the "SET key" again, the screen display "Set OK", and the time settings are successful.

7. Press the "SET key" behind the code watch for more than 2 seconds. The screen displays "SET Close", exit the setting mode, and then press "Big Key" to switch to time and check the setting time.

The average speed of the bicycle codes is not allowed

The biggest reason for the inaccurate speed of the bicycle codes is the incorrect setting of the perimeter of the wheels. Generally, the newly -bought bicycle sheet wheels need to be set. You need to accurately measure the size of the car, and then the code watch parameters follow the car circle according to the car circle.Settings.

The highest speed of the Bicycle code watch is not allowed

There are many reasons for the highest speed of the Bicycle code watch, but the reason is basically the same, that is, the wheels of the wheels have vibrated when the magnets of the front wheels pass through the sensor (sanitary Tube) through the code watch, such as overwhelming over the wheel, such as overwriting too much.A pit, a sudden brake, etc., made the magnet shake near the sensor of the code watch, so that the code watch thought that in this shaking time, the front wheels had turned around, so that there would be a very high high.Speed and recorded, this is normal, don't care.

1. Is it okay to wear Polarized glasses on cycling?

Many cyclists tend to choose Riding glasses with polarizing function when choosing Cycling glasses. Some riders do nt know why they need to wear Polarized glasses, so is it good for riding Polarized glasses?

1. The polarizer uses the principle of polarizing the light. When the sun is projected on the road or the water surface, it will directly stimulate the eyes, making the eyes feel dazzling, fatigue, and unable to stay visible.In addition to the scattered light in the beam, the light can put the eye visual image in the transmittance of the rail, making the field of view clear and natural, so it is more suitable for cycling.

2. In addition, polarizing Cycling glasses can also strengthen contrasts, reduce reflection, enhance the color of the scenery, and reduce the phenomenon of atmospheric fog, so that the scenes seen during cycling are clearer, and there will be no feeling of scene distortion and dizziness.Essence

3. sunlight will emit three types of light, light, infrared, and ultraviolet rays. Among them, ultraviolet rays will hurt the Skin and eyes of the human body. Wearing Polarized glasses can polarize the light and block the harmful light without affecting the harmful light.Through the visual light, protect the eyes.

In summary, it is very good to ride polarizing glasses.

2. How to choose the right polarized ride glasses

The choice of polarizing Cycling glasses is very important. It is related to the protection of the eyes during the cycling process. Therefore, it is necessary to purchase high -quality Cycling glasses through regular channels. It can be selected mainly from the following aspects:

1. Consider quality

The polarizing mirror is mainly used for anti -ultraviolet rays and filtration polarizers. Good Polarized glasses can block more than 90%of ultraviolet penetration, while inferior Polarized glasses will increase the damage to the eyes. ThereforeThere is a polarizer with the best blocking of UV400.

2. It is suitable for the truth of the vision

You can try it first when you buy it. Seeing how you feel, you should ensure that the color of the surrounding environment should be made after wearing the Polarized glasses, the edges of the object are clear, and the signal Lights of different color signal can be effectively identified.Safety.

3. Look at the quality of Riding glasses

You can ask the merchant to obtain a quality inspection report for cycling polarizers. Looking at its materials, processing, etc., high -quality polarized Cycling glasses usually use TAC polarizers, PC integrated polarizers, nylon polarizers, NXT color -changing polarized lenses, etc.Type type; In addition to the material, the main attention: The polarizing shaft installed after the polarization lens is installed in the frame should be in the horizontal direction, the deviation should not exceed 5 , and the difference in the direction of the polarized axis of the left and right lenses should not exceed 6 6

1. Do you have to wear a helmet on a bicycle?

The answer is yes, you must wear a helmet when riding a bicycle.This is not only responsible for your own life security, but also responsible for the safety of others.Let's explain in detail why you need to wear a helmet for a bicycle.

First of all, the helmet is the first line of defense of the bicycle cyclist.During the cycling process, if an accident occurs, the helmet can effectively protect the head and reduce the risk of head injury.According to research, head injuries are one of the main causes of the death of a bicycle accident.The helmet can absorb the impact and reduce the damage of the impact force on the head, thereby greatly reducing the risk of death and serious injuries.

Secondly, the helmet can reduce the occurrence of cerebral vibration.Brain vibration is a common trauma of brain, which may lead to long -term health problems and even affect the quality of life.The helmet can effectively protect the head and reduce the occurrence of brain vibration.

Furthermore, the helmet can also prevent faces and eyes from being injured.In a bicycle accident, faces and eyes are the most vulnerable parts.The Bicycle helmet can cover these parts to prevent them from being hit directly.

However, although the importance of a helmet is self -evident, in actual life, many people do not develop the habit of riding a bicycle and wearing helmets.Some people think that the speed of bicycles is slow, and there will be no big things; some people feel that the helmet is uncomfortable and unwilling to wear it; others are because they are troublesome or worried that the helmet will stain their hair and don't want to wear it.

These concepts are wrong.Although the bicycle is slow, once an accident occurs, due to the effect of human inertia, the power of falling is very large, which can easily cause serious damage.Moreover, the comfort of the helmet can be improved by selecting the appropriate model and adjusting the method of wearing.As for worrying that the helmet will soil the hair, you can choose a helmet that is breathable and easy to clean.

In addition, we need to know that the choice and use of helmets are also a science.First of all, the size of the helmet should be appropriate, not too large or too small; second, the buckle band of the helmet must be firmly fixed on the head; in the end, the validity period of the helmet is generally 3-5 years. After the expiration, a new helmet needs to be replaced.Essence

2. Can't check the helmet for a bicycle

At present, there is no clear traffic regulations in my country that riding a bicycle must wear helmets.However, this does not mean that wearing a helmet when riding a bicycle is not important.

In fact, the public security traffic police department has always suggested to wear helmets while riding a bicycle.Although most cities are forced to wear helmets for people riding electric cars, riding bicycles also have certain risks.When an accident occurs, the helmet can effectively protect the head from serious damage.

In recent years, in order to improve the safety awareness of citizens and ensure the safety of the people, the Ministry of Public security has increased its efforts in terms of traffic management.Especially for people who ride motorcycles and electric bicycles, they strictly check whether they wear safe helmets that meet standards.

Although cycling has not been forced to wear helmets, it is still necessary for those who have long bicycles or often travel to bicycles.Because once a traffic accident occurs, the head is often one of the parts that are most likely to be severely damaged.

In short, although there is no compulsory request for traffic regulations to ride a bicycle to wear helmets, for their own safety reasons, it is recommended that the majority of citizens wear helmets while riding a bicycle.

[riding on the knee pads] What is the importance of cycling knees?

What is the use of cycling knees

The ride knee pads are mainly exercise protection. Due to exercise, there is no fierce.There are various postures in the intense exercise. These intense postures easily hurt our knee joints, causing unnecessary damage or strain. Wearing knee protectives can protect the knee well and let the knees exercise during exercise.Keep it stable, while reducing the chance of knee injury.The other is the effect of keeping warm.Human knees are actually very fragile, especially in the cold winter.The role of the knee pad is to keep the knees warm and keep warm. Good warm knee -keeping, can ensure that the blood of the knee joint can circulate well, can resist rheumatism, etc., and prevent injuries when falling. Especially when the elderly go out in winter, wear knee pads.Can protect the knees resist cold wind and protect the elderly's knees from cold.

The braking effect of the knee pads.The knee joint is the place where the upper and lower leg bones are intersecting. There are half -moon boards in the middle. There is a Bone in front. The Bone is stretched by two muscles. It is very easy to slide before the legs of the legs.The influence is not strenuous, so the Bone can move normally in the knee.

Because the riding exercise has put too much pressure on the knee, coupled with the severe exercise in the cycling, it is easy to make the Bone be removed from the original part, which causes the disease of the knee joint.The knee pad can fix the Bone in a relatively stable position to ensure that it is not easily injured.

The above is the mild braking effect of the knee pads when the knee joint is not injured. After the knee joint is injured, the use of severe braking knee pads can reduce the bending of the knee, and maintain it from the thigh to the calf on a straight line to reduce the knee joint.Bending, thereby protecting the knee joint no longer aggravate the condition.

Some cyclists wear knee care while traveling, but often do not wear them short.I do nt know that frozen three feet is not a day s cold . The number of cycling is more frequently. For a long time, the knee joint will still get sick.When the lesion occurred, I regretted it.

The importance of long -distance ride knee pads

Generally speaking, most of the knee injuries are damaged by tissues that are not easy to regenerate because of cartilage and half -moon boards. These tissues do not quickly recover or grow like muscles.Glucose sulfate, but it is not advisable to take too much.Organizations such as cartilage and half -moon board are considered unspeakable for a few years or even more, so doing some targeted muscle exercises will help the rehabilitation and maintenance of knee tissues.However, many people who love cycling and often carry huge luggage Bags have tortured their knees because of high -intensity cycling, heavy load, and wrong riding positions, and finally the root cause.
