My e-bike,converted Giant Talon.Rear 3000w motor,72v 25amp hr battery,Savoton 72v/45A controller.The problem is since i had a 72v/60A Savoton controller fitted,which gives more power and speed,on hard throttle acceleration then power off the throttle, the motor will slow right down as if i put the brakes on instead of it coasting like the 72V/45 controller did.Any technical buffs out that can help me out thanx.
