What's in the Box
The next generation of bicycle sound generators is here! The Turbospoke bike muffler gives your bicycle the look and sound of a real motorcycle. The engine sounds start as soon as the wheels turn, so the sound changes with the speed of the bike.
The sounds are made by a thin plastic Motocard which is held against the spokes of the bicycle wheel. Includes three Motocards for tunable sound, mounting hardware and 15 decals for a custom look. With its variable spacers, the universal clamp will fit to almost any bike frame in minutes. For 16" or larger wheels.
