How do you know the size of your bike?

The size of a bicycle depends on the diameter of the wheel. 4 cm is equivalent to 1 inch.

Bicycles come in two sizes, one is the wheel diameter, 16/24/26/28/700C, etc.

One is the height of the frame. Men's frames are generally divided into 16 inch/17/18/19/20 inch.

Mountain bikes are 26-inch wheels, and the tires will write: 26* 1.95 or 26* 1.75 and so on.

Measurement method:

The size of a bicycle depends on the diameter of the wheel. 4 cm is equivalent to 1 inch.

The mountain bike runs from the center of the central axis to the upper end of the vertical pipe. In the case of the European version of the road vehicle, the center of the central axis extends horizontally to the center of the head pipe and to the size of the intersection point of the extension line of the vertical pipe.

Extended data:

The research results of modern sports medicine show that cycling has several benefits for people:

First of all, cycling can improve the regulation of the central nervous system to the musculoskeletal system. Therefore, alternating kicking can develop the left and right brain functions at the same time, which can effectively prevent the decline of brain function.

Secondly, cycling has a significant regulatory effect on cardiopulmonary function. Cycling can effectively exercise the muscle strength of the core and lower limbs, and at the same time make multiple muscle groups of the whole body participate together, so it can strengthen the whole body exercise endurance.

Another survey shows that people who ride bicycles for about 6.5 kilometers a day are 50% less likely to suffer from coronary artery disease than those who don't ride bicycles.

Cycling enthusiasts need to understand the "golden triangle counterweight principle". In the process of riding, put the body's center of gravity in the triangle composed of handlebar, seat and pedal, and distribute the body's load on three support points reasonably to reduce the pressure on the waist.

The correct riding posture should be:

Lean forward slightly, straighten your arms and tighten your abdomen. Adopt abdominal breathing method, and buckle your legs parallel to the beam of the car or slightly inward to keep the coordination between your knees and hips, and don't swing from side to side.

Pay attention to the rhythm of riding. Although many studies at home and abroad show that cycling is good for preventing cardiovascular diseases, unscientific cycling will further aggravate the existing cardiovascular and cerebrovascular diseases without scientific guidance.
