Bicycle Exhaust System

Maybe someday you’ll be able to have a real motor-cycle to ride on the streets, but in case you’re still sticking with your bicycle because it’s more fun and healthier to you, then you can at least make it look and roar like a motor bike, by mounting this TurboSpoke Bicycle Exhaust System! It comes with 3 waterproof Motocards, each producing a different engine sound when they make contact with the spokes!
