Chris, Maybe you didn't see my prior reply, but based on my Gizmo, a 6.7" motor can push it to 60mph but it will very quickly overheat and you will burn it up! Even though your rig is very likely more aerodynamic than a Gizmo a 6.7" is too small. I've burned up one already and that was only going 50-54mph on 50-60 mile trips. Even the longer 6.7" I have now is too small to go more than about 50mph continuously and that is with a cooling blower in addition to the internal fan. With batteries that last longer than the typical lead sled you cannot afford to undersize the motor if you will have the driving you are planning on doing. If you have the room you might want to seriously consider an 8" motor.
