  • Frame for bicycle
    Patent number: 10814932
    Abstract: A frame for a bicycle includes a front frame, a rear frame, an upper linkage, and a shock absorber. The rear frame is pivoted to the front frame at a main pivot axis. The upper linkage is pivoted to the front frame at a first pivot axis and is pivoted to the rear frame at a second pivot axis. The shock absorber is pivoted to the upper linkage at a third pivot axis and is pivoted to the front frame. When a compression ratio of the shock absorber is in a range between 0% and 60%, a distance variation between a pivot location of the rear frame at the second pivot axis and a pivot location of the rear frame at the main pivot axis reaches a maximum value thereof.
