Introduced in late 1998, a generator provides quiet resistance as the user exercises. Multiple sets of winding’s allow different resistance levels. There are three components to this resistance style; There is the generator, a relay control board and the console.
The generator provides resistance as the user pedals. As more winding’s are activated, the resistance increases. The relay control board is used as an interface between the console and the generator. The leads from each winding are attached to this board along with a wire harness from the console. There are a series of relays on this board that control the resistance of the generator. As more resistance is called for from the console, more of these relays will close, bringing more winding’s into the circuit and increasing the resistance. The console controls the resistance setting and displays information to the user. It is powered by batteries, but also uses the voltage from the generator to ‘back light’ the display.
