Abstract
An adjustable bottom bracket mechanism, comprising: a bottom bracket, an axial connection portion and a mounting portion. The bottom bracket includes at least one shaft through hole and is configured for connection of a seat tube. A lengthwise extension direction of the seat tube is defined as a first direction. The axial connection portion includes at least one axial through hole and axially corresponds to the at least one shaft through hole. The mounting portion is connected to the axial connection portion and adjustably fixedly connected to the bottom bracket in a first position or a second position. When the mounting portion is in either of the first and the second position, axes of the at least one shaft through hole and the at least one axial through hole are located on the first direction.

- a bottom bracket, including at least one shaft through hole and being configured for connection of a seat tube, a lengthwise extension direction of the seat tube being defined as a first direction;
- an axial connection portion, including at least one axial through hole and axially corresponding to the at least one shaft through hole, the at least one axial through hole and the at least one shaft through hole being configured for insertional connection of a bottom bracket shaft;
- a mounting portion, connected to the axial connection portion and adjustably fixedly connected to the bottom bracket in a first position or a second position;
- wherein when the mounting portion is in either of the first position and the second position, an axis of the at least one shaft through hole and an axis of the at least one axial through hole are located on the first direction;
- a position of the axis of the axial through hole, when the mounting portion is in the first position, is different from a position of the axis of the axial through hole, when the mounting portion is in the second position, on the first direction.
