This invention is provided in order to allow an auxiliary power supply apparatus for bicycles to be reliably and rigidly attached to manually-driven bicycles to convert them into practical motor-driven bicycles. An annular activating wheel (9) is attached to spokes (8) of the bicycle driving wheel (7), and the driving device (G) including a driving wheel (12) rotated by a motor (19) and a speed-reducing device is attached to a seat or a chain stay (14,18) using a bolt. The driving wheel is coupled to the annular activating wheel (9).
