Hi, Was checking the posts and saw your question. The people who make the controller have a programming download to change settings(speed, current, etc.) I wanted to use the half current option but it doesn't enable when I click on it. The motor is paired to the original 5 speed gearbox, and the motor spins the same direction all the time. I have tried easing the throttle but the torque is frightening. Am adjusting the motor speed and current settings to see if that works. Will check at a welding supply store local for some liquid solder for the lugs. Have a good one. Watt
