A magnetic driving apparatus includes a base, at least one passive magnetic unit, and a switching unit. The at least one passive magnetic unit includes two passive magnets movable on the base and a translation-to-rotation device for interconnecting the passive magnets. The switching unit includes two active magnetic units, and a driving unit. The passive magnets are located between the active magnetic units. Each of the active magnetic units includes at least two active magnets. The amount of the active magnets of each of the active magnetic units is the amount of the at least one passive magnetic unit plus one. The driving unit reciprocates the active magnetic units between two positions relative to the at least one passive magnetic unit so that the active magnets reciprocate the passive magnets.

Electric power can be generated by using an existing bicycle without impairing the durability of the tire of the bicycle. The bicycle generator device (50) comprises a housing (52) configured to be attached to a frame (18) of a bicycle (10), a generator (54) attached to the housing (52), an annular rotational input member (81) for rotationally driving the generator (54), the rotational input member being rotatably mounted on the housing and positioned around a crank axis line which is a rotational center line of a crankshaft (24) and a crank arm (26) for a pedal of the bicycle, and a connecting member (90, 130) connecting the rotational input member (81) to the crankshaft (24) or the crank arm (26) in a torque transmitting relationship.

A reciprocating motor comprising SSR's Solid State Relays, photoelectric switch sensor and semicircular reflective surface, a wiring circuit for converting DC direct current to AC alternating current as an output current used to switch the electromagnet poles having as a result the attraction and repellent reaction with magnets poles located in the pistons. These said pistons are moving up and down (reciprocating motion) getting the rotation motion of the crankshaft and therefore the mechanical motion of the motor. The photoelectric switch sensor controls two sets of Solid State Relays, the wiring circuit of the sensor, relays and electromagnet allow an alternating current and therefore switching of poles. The electromagnet has a “U” shape for using both poles to be used in the reciprocating system. The circuit has an optional switch to turn off the circuit in the attraction moment, this is for saving energy when the torque required is low.
