When you were a kid, did you ever put a baseball card in the spoke of your bicycle wheel to make it sound cool? It was a fairly effective method, though these days it just doesn’t have the same feel. Kids want more than a simple card flicking along in their spokes. That’s why the Turbospoke was created.

The Turbospoke actually works much the same way as the old card trick. It has a set of strong plastic cards that are positioned between the spokes of your rear tire. They are connected to a tube that’s made to look like an exhaust pipe. This acts as an amplifier, which helps to create a sound not unlike a small engine would make. The best part is that it only costs $20, and will make your kid’s bike the coolest on the block.
