The invention relates to a bicycle frame, in particular to a pendulum suspension bicycle frame which comprises a head tube, an upper main tube, a lower main tube and a rear triangle, wherein the head tube is provided with an upper fixing part and a lower fixing part, the front side of the upper main tube is provided with an upper main tube fixing part, the front side of the lower main tube is provided with a low main tube fixing part; the back side of the head tube is provided with a shock-absorber, both sides of the shock-absorber are correspondingly connected with the upper fixing part and upper main tube fixing part in a hinging manner or connected with the lower fixing part and the lower main tube fixing part in a hinging manner; when the upper fixing part is connected with the upper main tube fixing part in a hinging manner, the lower fixing part of the head tube and the lower main tube fixing part form a shaft; when the lower fixing part of the head tube is connected with the lower main tube fixing part, the upper fixing part of the head tube and the upper tube fixing part form a shaft; when the bicycle body is impacted from the front and rear direction or the upper and lower direction, the head tube can rotate around the rotating shaft, and the impact force from the outside can be absorbed through the shock-absorber. The pendulum suspension bicycle frame has the advantage that the shock absorbing effect is good.
