A bicycle component for an at least partially muscle-powered bicycle with at least one freewheel unit including a freewheel component and a support unit and a spring unit, the freewheel component containing a tubular body section extending around a central axis and configured hollow showing a non-round outer contour for non-rotatable and axially displaceable coupling and a front surface with axial engagement components. The spring unit urges the freewheel component and the support unit apart in an axial direction of the central axis. The freewheel component, the support unit, and the spring unit form an assembly suitable for pre-assembly, and the spring unit is attached to the freewheel component and the support unit.
