Since changing to a KT controller I have done a 32 mile round trip in power assist level 3. I think it is in torque mode as the wattage stayed the same throughout, round about 300w. On my 13ah 48v battery I finished the journey with 4.55v which to be fair is nearly dead, but there are some mighty hills on the trip one which I needed to boost it to power assist 4 to conquer. With my previous controller I was lucky to get 15 miles out of it. Truly amazed.
