The Racing wheel is a pretty nifty concept built around an idea that’s unusual, but clever. It just involves fixing a stick with LEDs to the cycle wheel. The faster the wheel moves, the more electricity is harnessed, allowing the LEDs to light up. Persistence-of-vision, a phenomena common in us humans, allows us to therefore see a disc of light that’s actually the rotating wheel of the bike. That, however, isn’t the clever bit. These LEDs light up differently at different speeds, which means it’s easy to tell what speed the biker is going at… Not to mention it also makes the biker more visible in low-light conditions, avoiding the possibility of an accident. The Racing Wheel module is a winner of the Red Dot Design Award for the year 2015. Designer: Chen Hsin Hui
