Drive arrangement for a bicycle or pedelec

A drive arrangement for a bicycle or pedelec, comprising:

• a housing (2);
• a manual drive shaft (1) in the housing (2);
• a first electric drive (EM 1), a rotor (3) of the first electric drive (EM 1) arranged axially parallel to the manual drive shaft (1);
• a second electric drive (EM2), a rotor (4) of the second electric drive (EM2) arranged coaxially to the manual drive shaft (1);
• a first planetary gear set (PS 1), the rotor (3) of the first electric drive (EM 1) coupled to the first planetary gear set (PS 1) as a superposition gear via a first fixed ratio;
• and
• another planetary gear set (PS 3) configured to provide the first fixed ratio between the rotor (3) of the first electric drive (EM 1) and the first planetary gear set (PS 1),
• wherein the rotor (4) of the second electric drive (EM 2) is coupled to the manual drive shaft (1) via a second fixed ratio, the manual drive shaft (1) is coupled to the first planetary gear set (PS 1) as the superposition gear, and the first planetary gear set (PS 1), as the superposition gear, is coupled to an output (5).
