Abstract: The invention provides a generator for a bicycle. The generator has one or more driving magnets fixed to a wheel of the bicycle and an induction structure that is fixed to a frame part of the bicycle. The induction structure comprises an induction magnet and a coil. A fixture allows fixing of the driving magnets at locations where they, during operation of the bicycle, repeatedly moves towards and away from the induction magnet. The generator comprises means for reorienting the induction magnet so that it is optimally oriented when a driving magnet approaches. Such means comprises a first driving magnet or a structure of magnetisable material which is magnetisable by the driving magnet.

Abstract: The invention relates to an electrical generator for bicycles and similar vehicles. The generator includes a moveable magnet part which will generate an induction current in a coil when the magnet part moves. The generator is configured to be mounted near an electrical conducting part of the bicycle. The electrical conducting part, e.g. a rim, is rotatably arranged with the bicycle. When the electrical conducting part rotates the magnetic field from the magnet part will generate eddy current in the electrical conducting part. The eddy current will generate a magnetic field which will force the magnet part to move, e.g. rotate. Thus, an electrical current will be generated in the coil when the electrical conducting part rotates.

Abstract: The invention provides a generator for a bicycle. The generator has a driving magnet (2) fixed to a wheel of the bicycle and an induction structure which is fixed to the frame of the bicycle. The induction structure comprises an induction magnet (3) which is movably fixed to a coil (4). A fixture allows fixing of the magnets at locations where they, during normal operation of the bicycle, repeatedly moves towards and away from each other so that the driving magnet moves the induction magnet relative to the coil. To provide a generator which can potentially deliver a uniform output which is less dependent on a very specific installation of the generator, on the bicycle and which may therefore be easy to install, the generator further comprises a resetting magnet (5) which provides positioning of the induction magnet relative to the coil when the driving magnet moves away from the induction magnet.
