Beschreibung
Zusammenfassung:	The utility model discloses a bicycle electronic speed change device and a bicycle. The device comprises a speed change mechanism, an electric driving mechanism and a gear position sensing mechanism, the speed change mechanism comprises a speed regulation unit, a push plate and a release plate; the electric driving mechanism comprises a forward gear driving wheel used for pushing the pushing plate to move, a backward gear driving wheel used for pushing the releasing plate to move and a driving motor used for driving the forward gear driving wheel and the backward gear driving wheel to rotate. The forward gear driving wheel is connected with a main shaft of the driving motor through a one-way bearing, and the backward gear driving wheel is connected with the main shaft of the driving motor through a one-way bearing. The gear position sensing mechanism comprises a gear mechanism arranged on the speed regulation unit and a sensor used for sensing the movement position of the gear mechanism. According to the devi
