Abstract
A control device of the height adjustment for a bicycle seat post is a pull-down control device secured to the bottom end of the lower outer tube of the seat post. A linkage mechanism is managed by a controlling wire driving the main pin of the oil hydraulic mechanism to axially move upwards to adjust the height of the seat post. Besides, the control device includes the linkage mechanism instead of an oil hydraulic mechanism, so it requires less elements and avoids oil leaking as well as working hours consumed occurring in the prior art control mechanism of the height adjustment for a bicycle seat post. Consequently the control device increases the stability in operation and the speed in assembling.
