Hi people, im a massive noob thinking about getting a conversion kit, iv done some internet research and priced up a few things and heres what iv come up with.... If i get a 36v 750w rear brushless motor kit and 4 12v 20ah batteries then i should be able to go about 20-25mph and a distance of about 20-30 miles, is this correct?? Also would i be better off with a 1000w motor? Or less/more amp batteries? I know if i take 4 12 volt batteries it makes 48 volts is this enough?? Basically any advice on what iv just said on the above would be greatly appreciated thankyou.
