The Protanium shaft motor is almost like a normal shaft drive and an electric motor built together so that the rider and the motor draws on the same axle for optimum traction and weight savings. Through a set of internal clutches the cyclist will not feel any resistance from the engine when the system is off. The feeling will be like riding a normal bicycle without a motor. The internal mechanical clutches are also arranged so that when the cyclist pedals backwards no resistance is given from the motor. This means that Protanium shaft motor is perfect for coaster brake.
