Beschreibung
Zusammenfassung:	An electromotive auxiliary power assembly for a chainless shaft-power-transfer bicycle comprising: a frame, a crank assembly, a crank, a power transfer shaft between the crank assembly and a passive gear of a rear wheel hub of the bicycle, and a motor set for providing auxiliary power; the auxiliary power of the motor set being directly transferred to the power transfer shaft through a gear set instead of by other components of the chainless bicycle. The motor set is installed on the power transfer shaft between the crank assembly and the passive gear set of the rear wheel hub. Even the motor set is installed on the power transfer shaft extending from a crank shaft of the crank assembly. Furthermore, The power output shaft of the motor set is coaxial or non-coaxial with, parallel or non-parallel with , or penetrates through or non-penetrates through the power transfer shaft.
