Playing off the age-old baseball card in the bicycle spokes trick, Turbospoke is a new bike add-on shaped like a motorcycle exhaust that mimics motor sounds. The system still relies on cards — in this case, three waterproof ones with unique sounds — that clap on the bike’s spokes as you ride. The sound is then amplified by the hollow plastic exhaust tube. You can purchase the Turbospoke now through Vat19.
