given the lack of distance what is the point of these 300WH 350W S class bikes? they are in a legal grey area,it appears they aren't much use for more than a sprint to the shops and ( except perhaps in the case of this "under fuelled" example) are quite costly Still if someone was looking to customise this could be start. thanks for the breakdown it helps when trying to compare like with apparent like in what is a relatively complex field.
