Thank you for viewing! No comments needed, instant purchase is OK (o^^o) This is a saddle cover that can be used on any bicycle, such as regular bicycles, mama-chari (city bikes), and electric bicycles! Installation is very easy. The back of the cover can be expanded like a drawstring bag, so just put it over the saddle and tighten it! This is a low-rebound type cover, so it's a highly recommended item for those who spend a long time riding a bicycle, such as for commuting to school or work, or for picking up and dropping off children at nursery school or kindergarten.
