The invention relates to the technical field of motorbikes, and discloses a motorbike antiskid device. The motorbike antiskid device includes a motorbike frame. One side of the motorbike frame is fixedly connected with a supporting beam through a fixing bolt. The top of the supporting beam is fixedly connected with an arrangement beam. The top of the arrangement beam is fixedly provided with a fixing sleeve. The top of the fixing sleeve is fixedly connected with a flexible sleeving rod. The surface of the flexible sleeving rod is connected with a flexible spring in a sleeved mode. One side ofthe fixing sleeve is fixedly connected with a moving rod and the moving rod is movably connected with a sliding block. The top of the sliding block is fixedly connected with a connecting rod through afixing pin. According to the motorbike antiskid device, through arrangement of an antiskid plate, anti-skid convex stripes and convex edges, by using the fact that the antiskid plate is fixedly arranged on a pedal plate and the multiple anti-skid convex stripes are arranged on the antiskid plate, force of friction on the surface of the pedal plate is increased so that the aim of antiskid is achieved; meanwhile, the six convex edges are arranged on the pedal plate; and force of friction on the pedal plate is further improved and the antiskid effect of the pedal plate is improved.
