Description

Rider frame extension structure

The invention relates to the field of bicycles, and in particular to a rider frame extension and lowering structure that provides riding safety and comfort.

It is well known that the handlebars of a bicycle steering structure are at a fixed height and therefore cannot be adjusted for individuals. Users of different heights can only ride with the handlebars at a fixed height, which can easily cause discomfort after long periods of riding and can also cause problems with the user's posture and appearance.

However, when the conventional bicycle steering structure is fixed to a front fork, usually only a bunch is used to fix the bicycle steering and the front fork at the same time. However, simply using the bunch as a fixing means will not allow the user to rotate the bicycle while riding. When the bicycle is steering and the front fork, it is easy for the bicycle steering and the front fork to shake each other due to speed, bumps on the ground, etc., making the vibration more intense and causing safety concerns.

In addition, the conventional bicycle steering structure includes a headset, a head tube and an inner tube, the head tube and the inner tube are mutually interpenetrating, and the headset includes an upper headset and a lower headset, the upper headset and the lower headset are respectively connected to the two ends of the head tube and connected to the inner tube, so that the inner tube can be limited to the head tube and rotate relative to the head tube.
