I have just bought a used Sakura E-bike which I only intend to use now and then and I have been looking at the chains available on Ebay and other retailers. I have noticed all the modest priced ones (which is all I can afford) refer to the chain as "Heavy Duty Motorbike Chain" and even some of the dearer ones have the same description. What does this mean exactly? Is it Heavy Duty because it weighs heavy or is it definitely a stronger steel or what. Any information would be gratefully received to enable me to choose the right one.
