Custom OFFROAD wheelchair, sip and puff controls, can be used if you plug in a joystick. driving lights, 4 wheel independent suspension, electric motors. I have small front tires on it now but i did have large knobby tires on it at one time. I put the smaller ones on to increase torque for going up a hill i had to go up to get back from our beach. It has been sitting in my shed for 3 years not being used so i have to let go. I am not able to use it due to medical reasons. It will probably need new batteries and a good cleaning. make offer
