The invention discloses cycling trousers. The cycling trousers comprise a trouser body and a belt; the outer surfaces of the knee areas of the trouser body are fixedly provided with first wear-resisting layers which are made of a composite fabric containing 70% of polyester fiber and 30% of flame-proof vinylon. By means of the first wear-resisting layers fixed arranged on the knee areas, the cycling trousers can ensure the wear resistance of the trouser body and accordingly reduce the risk of injury to a user during a motorcycle accident; also, the cycling trousers reduce restriction to materials of the trouser body and greatly improve the comfort level; meanwhile, the first wear-resisting layers are light in weight and are fixedly connected with the trouser body, thereby avoiding falling off and ensuring reliable protection for the user when accidents occur.
