Using your bicycle is about as green as you can get, but one of the things you sacrifice is the sound of power from a car or motorcycle. Well you won’t have to do without that feeling of power anymore thanks to the TurboSpoke Bicycle Exhaust System.
This gadget will make your bicycle sound fast and powerful. Installation takes less than five minutes. That means you will be a noisy nuisance in no time. The TurboSpoke uses durable “Motocards” and an special clamping and amplification system to make your bike roar like a cycle. That basically means they are using the old “card in the spokes” trick and then amplifying the sound.
With your purchase you get three waterproof Motocards that each produce a special engine sound. Just $19.95 from Vat19.
