A bicycle dynamo having enhanced power dynamics by having a large number of magnets 63 in alternate polarity lined up at a fixed interval along the inner circumference of the rotating mechanism 60. A circular lining 70 is outfitted and anchored around the perimeter of the main axle 20 with a transformer strapped to it. The transformer container a coil unit 81 and tow core parts; with the two core units sandwiching the coil unit 81 at its two sides. Each of the core unit is a stack having two or more core discs 82a, 82b. At an even interval around the circumference of the core disks 82a, 82b, fixed number of raised anchors 821a, 821b are formed that interconnect with different core disk anchors 821a, 821b to form a fixed set of the claw unit. Furthermore, each of the claw unit from the two core components 82 are extended out between the coil unit 81 and the magnets 63.
