I know the 48V kit I have can pull along 400lbs... but according to the OEM that is the limit. The e-bike I tried before starting my current project had four 12V 18ah batteries. The batteries themselves weighed 52 lbs. I know that doesn't sound like a lot but the bike itself weighed about 60lbs... With a 180lb rider and a few bike accessories you are chugging along with over 300lbs!
