I faced the exact same issue. Now, my problem is solved by setting correct values. Please see attached image and set value's according to your motor voltage. My motor is 48v1000w using KT controller with KT LCD3 display.
48V1000W Direct Drive. Max Speed 55Km/hr.
OP. Did you find a solution yet?
I am facing the exact issue as yours. Example I going at speed 40km/hr then take your hands off on throttle and immediately resistence/regen kicks in thus slowing down the momentum. When you raise throttle again you will see motor moving forward and so much...
