They typically retail for ~$500. Cost ~$100 to ship via freight. Then need to add ~$100 battery. So ~$700 new. They lift the kart off the ground and put it back down. Really saved my back!
I have two:
1. The one shown. I’ve upgraded the winch electronics by replacing relays with a winch solenoid. I’ve also upgraded the control lead to a heavier duty cable. And this one comes with a battery. $500 OBO.
2. A second one that is very similar, but hasn’t been used as much. I haven’t modified this one at all, and it does not include a battery. Barely used. $400 OBO.
