An exhaust system for your bike that makes realistic engine sounds as you cycle.
The Turbospoke works by a clamp easily fitted to the frame of your bike with a tuneable motocard slid through the clamp, which gets held against the spokes of the wheel. When the wheel turns the Motocard vibrates and makes one of three engine sounds - the megaphone exhaust pipe then makes the sound louder. Fits any 14" + wheels, is 100% waterproof, is easy to fit and comes with 24 custom stickers for adding street cred. Just add pedal power - vroom!
