Abstract
A bicycle seatpost includes a first part and a second part. A curvature radius of the first part is r1, and an arc length of the first part is equal to or greater than πr1 and smaller than 2πr1, the first part is set toward a head of a bicycle. The second part is connected to the first part, wherein a curvature radius of the second part is greater than the curvature radius of the first part, the second part is set toward an end of the bicycle.
