Abstract

A power supply device for bicycles is specified, in which a disk-shaped armature (44) is arranged in a fixed manner between permanent magnets (47, 48) rotating with the hub of a wheel. The armature is constructed as copper-coated insulating armature having conductor tracks in rotary current technology. Neither carbon brushes nor other wearing parts are present, so that a closed housing can be used (FIG. 1).
