A bicycle frame with a rear shock absorber comprises a front frame body, a rear frame body, at least one connecting rod, a transmission part and the rear shock absorber. The rear frame body can be pivoted with the front frame body in a manner of rotating around a first axis; the at least one connecting rod is provided with a fixed pivot part which can be pivoted to the front frame body in a manner of rotating around a second axis, and a free end part opposite to the fixed pivot part; and the transmission piece can be pivoted with the free end part in a manner of rotating around a third axis, and can be pivoted with the rear frame body in a manner of rotating around a fourth axis. One end of the rear shock absorber can be pivoted with the transmission part in a manner of rotating around a fifth axis, and the other end of the rear shock absorber can be pivoted with the front frame body in a manner of rotating around a sixth axis; therefore, when the rear frame body is stressed to drive the rear shock absorber to be compressed, the rear frame body does not deform, so that the material fatigue of the rear frame body is reduced, and the service life of parts is prolonged.
一种具有后避震器的自行车架,包含前架体、后架体、至少一个连杆、传动件及后避震器。所述后架体能绕第一轴线转动地枢接所述前架体。所述至少一个连杆具有能绕第二轴线转动地枢接于所述前架体的固定枢部,及相反于所述固定枢部的自由端部。所述传动件能绕第三轴线转动地枢接所述自由端部,并能绕第四轴线转动地枢接所述后架体。所述后避震器的其中一端能绕第五轴线转动地枢接所述传动件,另外一端能绕第六轴线转动地枢接所述前架体,借此所述后架体受力而带动所述后避震器压缩时所述后架体不会产生形变以降低所述后架体的材料疲劳度以增加零件寿命。
