Turbospoke Bike Exhaust System
No batteries or complex electronics are involved. The Turbospoke attaches to most bike frames using a universal mount and lets you choose one of three sound cards for different engine notes. This flexible sound card connects with each of your spokes as the rear wheel spins, creating a clattering effect that’s magnified and channelled through the exhaust-shaped tube. So as you change pace from slow to fast, the sound will change. Vroom-vroooooom!
