<p>An exercise apparatus is mechanically engaged with an electrical current producer so that exercise by a person using the apparatus produces output power which is used at the time of exercising or saved for later use. A motor provides additional drive force by rotating a rotor engaged with the apparatus, the rotor operating by magnetic attraction and repulsion depending on relative positions of permanent magnets on the rotor and electromagnets on a stator. The apparatus is light in weight, low cost to produce and highly durable.</p> |
