The invention discloses a bicycle saddle and a forming process thereof. The forming process of the bicycle saddle comprises the following steps that S1, preparation of mold: an upper mold and a lowermold of the bicycle saddle are prepared; S2, plastifying and extruding: the raw materials of the bicycle saddle are injected into a mixing mill, mixed into a molten material, and extruding and granulating are carried out to obtain particles; S3, mold closing: the particles in the step S1 are fused and then injected into a cushion cavity formed by the upper mold and the lower mold, steam is injected into the cushion cavity after injection is completed, and the mold closing time is 6-10 min; and S4, cooling and demolding: after the bicycle saddle is cured, cooling and mold opening are conducted,and the bicycle saddle is taken out. The bicycle saddle has the advantages of being lasting in elasticity, good in abrasion resistance and durability, comfortable in hardness, environmentally friendly, antibacterial and capable of preventing stuffiness.
