I have been reading about all the problems that people have with their electrics on their e bikes. So what i would like to know why can manufactures of e bike not fit a diagnostic plug on the bike then you could buy the diagnostic test system read the code and then order the part from the suppler. A lot of people buy e bike,s but have no dealer backup near them if i had been offered this as a extra for say £200 i would have bought it.
