Abstract

The invention relates to a drive system for a motor-assisted bicycle, comprising a shaft (2) that can be driven by means of cranks, a motor unit (3) having a stator (5) and a rotor (4), and a planetary gear train unit (6) driven by the motor unit (3) and having a sun (7), at least three planets (8), a planet carrier (9), and a ring gear (10), wherein the sun (7) is driven at least indirectly by the motor unit (3), wherein the planet carrier (9) is connected to the shaft (2) in a rotationally fixed manner by means of a form closure. The invention achieves the aim of specifying a drive system for a motor-assisted bicycle that is easy to assemble and reliable in operation. The invention further relates to a housing for a drive system having a shaft (2), a motor unit (3), and a planetary gear train unit (6).
