Boy are we late to the game on this one. Apparently out since 2011, the Turbosopke Bicycle Exhaust System is designed to give your human-powered bike somewhat of a growling motorcycle sound. It’s an expansion on what kids have been doing… pretty much sine they’ve been riding bikes:
TurboSpoke utilizes durable “Motocards” and an effective clamping and amplification system to make your bike roar like a four stroke engine.
Each TurboSpoke comes equipped with three waterproof Motocards, which each produce a different engine sound when struck by the spokes of your bicycle. The lightweight and durable exhaust “pipe” acts like a horn to increase the volume produced by the Motocard.
It’s a stupid little toy, but it’s fun nonetheless. At $24, it’s a cheap gift for a child of any age.
