I privately purchased a used E-Wind e-bike however awhile back. Now the battery will not hold a charge and requires a replacement. The E-Wind bike manufacturer in China no longer exists and I do not know how or where to find a replacement. It sits vertically under tr seat so it must fit into the slot to slide down and into the 4-prong connection to the controller. This is also a problem as many I have see on-line are to long (back-to-front). I have 85mm and all I see now is 110mm. See pics.
Can anyone help please ... ?!?!?
