I have a Polaris E-Bike that I need some help to get running. I checked the Battery and it seems healthy. This bike had all kinds of crazy features like gear speed technology, Back Pedal Regen, Active Trail Mode. This was cool sounding but unfortunately was very misleading considering the bikes actual abilities. Of course the company went out of business and a third party picked up the remaining parts inventory. I asked them to send me a wiring schematic for the bike which they do not have. I want to get this bike running again and skip all this fancy termed technology and just end up with a Pedelec Bike. It has two very fancy control boards in the battery housing. I can't tell what they are for or how to modify without a wiring schematic. Can I just rip them and get a off the shelf BMS to make this motor run. Can anyone give me some advice.
