The listing isn't correct. The photo shows the 4.4kg Xofo CST rear motor. The drawing shows a front motor. You should check with the supplier which one it actually is.Thanks. It sounds good. But I suppose the question I need to ask is will the Xofo CST cope with long hills without melting in the way a Bafang BPM motor allegedly can. At 2.2kg it is smaller than a lot of motors like the SWXK which are thought not to be the hardiest.
