On three batteries a combined riding total since 2011 of 27,201 miles. The oldest batt range is at 8miles at 12mph. All batteries are 48volt 15ah. The range of the second oldest is 12mph with a constant speed of 20mph. The newest battery range is at 18miles at an average speed of 19mph. I am now waiting on the newer Graphene Solid State batteries before I invest again. There are other newer batts coming as well.
