Cyglo is a company based in the UK who has been awarded a couple of patents in the US and UK to sell what could be the next craze in bicycle fashion and um safety. The Cyglo tires, or “tyres” in British English, use embedded LED lights within the sidewall or top of the tires. The LEDs can either blink or stay on permanently; when the wheel turns at any speed, the highly visible ring of light is formed. The best part about it, there’s no battery pack or other contraption required to power the Cyglos. They are “continually and perpetually” creating their own power as the tire spins.
