Abstract
A bicycle seatpost structure mainly provided with a shock absorber includes a sealed chamber, a buffer element and a gas. The gas is filled in the sealed chamber to change a gas pressure in the sealed chamber. The buffer element is elastic and installed in the sealed chamber for providing an upward elastic support force to an up tube of the seatpost. When a rider sitting on the saddle presses at the saddle, a shock damping force is produced, and the shock damping force and flexibility may be adjusted by the gas pressure and changed anytime according to the rider's body weight or preference.
