Parametry čínských komponent pro stavbu elektrokol se velice špatně dohledávají. Dokonce i tak proslulé značky, jako je Bafang (8fun) jsou na informace velmi skoupé, a na svých stránkách mají minimum informací. Něco málo se dá "vygůglit", ale velká sláva to taky není. V tomto článku chci zaznamenat informace o nábojových motorech, které se mi dohledat podařilo.
