Generally, a bicycle moves by moving a wheel through a chain by stepping on a pedal with two legs. In the past, it was mostly used as a means of transport, but it has been widely used for sports purposes in recent years.

Bicycles must be used in the correct posture to make a balanced body. For proper posture, you must choose the bike that matches your body type. If the saddle is low and the legs are bent in a very bent state, the muscles in front of the thighs are used intensively, while the muscles of the thighs and the buttocks are only used a little, Is not achieved. Also, if you ride your bicycle for a long time with the saddle height not adjusted properly, you may not be able to ride because you may come to your body such as your knees.

Therefore, the desirable height of the saddle when using a bicycle is that the knee is slightly bent when the pedal is touched while the shoe is worn and the foot is extended. And the forearm is placed on the pedal to bring about a natural rotation in the knee joint, and the lower body's overall uniform muscle development is achieved.

However, since the toe is not touching the ground, the frame must be tilted down when getting off the bicycle. In this process, a stable landing may not be achieved. In case of an urgent situation, a person may be injured when falling down while suddenly falling down. This occurs more frequently, especially in young children.

A bicycle which solves such a problem is described in Korean Patent No. 10-0700902, and its structure will be described as follows. A bicycle seat assembly in which a driver can alternately sit at a first position or a second position in a bicycle having a pedal, the bicycle seat assembly comprising: first and second seat members, the second seat member being smaller than the first seat member; A first means for supporting the first seat member at a first position on the bicycle pedal at a distance that the foot of the driver touches the pedal with the leg of the bicycle driver fully extended; And second means for supporting the second seat member in a second position at a distance above the ground where at least one foot of the driver can touch the ground under the bicycle, wherein the first and second seat members It is made up of an integrated structure.

The bicycle having such a structure can efficiently turn the bicycle pedal by the driver at the first position and can easily hold the bicycle at rest in the second position.

However, these bicycles can only adjust the saddle in the vertical direction, but can not adjust the position in the forward and backward directions. In this way, since the distance between the handle and the saddle can not be adjusted, there is a problem that it can not be used in the correct posture.

First, in order to adjust the height of the saddle 40, the saddle 40 is placed on the saddle 40 and the saddle 40 is positioned between the thighs. Then, the saddle 40 is lifted up and brought into close contact with the buttocks, The position of the saddle 40 becomes the point A and the floor of the foot becomes the point B so that the points A and B are perpendicular to the ground do. In this way, when the user is sitting on the saddle 40 and the leg is lowered on the ground, the soles of the feet are brought into contact with the ground.

The heel is placed on one pedal P and the leg is straightened to adjust the distance between the saddle 40 and the pedal P so that the crank CR is rotated and positioned at the farthest point from the saddle 40 do. This is the 'C' point located on the hypothetical line passing through the saddle 40 and the CR axis and the saddle 40 is naturally pushed back along the guide bar 30 and stops at the position where the leg is fully extended. When the clamp CL of the slide tube 50 is tightened in this state, the height and position of the saddle 40 are adjusted. In such a state, when the forefoot is placed on the pedal (P), the knee is slightly bent, and it becomes the correct state when driving. In this process, a person with a large body naturally moves away from the 'D' point where the handle H is located and the 'A' point where the saddle 40 is located. The distance between the point and the 'A' point where the saddle 40 is located is narrowed. If you want to stop while driving in this state, or if you suddenly go to a sudden situation, your feet will land on the ground without your bicycle tilting. Therefore, it can be stopped in a stable state.
