The invention discloses a bicycle drive system (10) and a kit. The drive system comprises a drive unit (15) comprising a housing, a motor unit (20) having a stator (21), a rotor (22) and an output shaft and accommodated in the housing, and a first stage deceleration unit (30) having an input part connected to the output shaft of the motor unit and an output part; a mounting unit (50) configured to secure and hold the drive unit on a bicycle body (70); and a second stage deceleration unit (40) arranged external to the drive unit and detachably mounted on the first stage deceleration unit for connection to a pedal assembly (80) to transfer a drive force from the output part of the first stage deceleration unit to chainrings (82) of the pedal assembly. The drive unit, the mounting unit and the second stage deceleration unit are each provided as a modular part for assembling to the bicycle. The invention provides a customizability of the drive system.
