    At reaching the pre-set speed, torque is cut back. The low torque is set to a rate, compensating the friction, for the most part, caused by the belt and by air drag of the wheel. Torque reduction is accomplished by lowering the voltage supplied to the motor with an AC controller, located on the Integrated Display board.
