A toy exhaust pipe assembly for a bicycle, comprising:

• an exhaust pipe comprising three sections, including:
• an elongate cylindrical tube section having an axis of symmetry, and a first cylindrical tube plane of symmetry that includes the axis of symmetry;
• a tubular neck section having a base connected to a proximal end of the elongate cylindrical tube section, the tubular neck section having a tubular neck plane of symmetry;
• and
• an A-shaped mounting bracket section having a distal end connected to a proximal end of the oblique frusto conical neck section, the A-shaped mounting bracket including a first orifice on a first side and a second orifice on a second side, and the A-shaped mounting bracket section having a mounting bracket plane of symmetry;
• wherein the first cylindrical tube plane of symmetry, the tubular neck plane of symmetry, and the mounting bracket plane of symmetry all coincide in a common plane.
