This is a chain cover (mudguard) for a folding bicycle. I am selling it because I am replacing it. It is the initial equipment for the tern byb. I think chain covers for folding bicycles are rare. How about it for those who use it for commuting, etc.? #Mudguard #ChainCover #ChainGuard #Mudguard I am also exhibiting a stand and crank, so please consider those as well.
