In many ancient cultures, traditional patterns are imbued with symbolic meaning that turn the objects on which they appear into amulets believed to bestow powers that protect a person from danger or harm. What better place to add this extra measure of safety than on a bicyclist’s headgear. Korean designers Kim Jungwoo, Kim Yoonsang and Park Eunsug found that the dramatic Sun Ja Mun pattern, a symbol for love, living and luck, was well suited to the cut-out design of a bike helmet, and also appealed to the bike rider’s philosophy of life.

Designed and built by Ethan Frier and Jonathan Ota, two industrial design students at Carnegie Mellon University, Project Aura is an ingenious solution for making bicyclists more visible at night. That’s the time of day when most bicycle fatalities occur. Thirty-six percent of these accidents happen at intersections. One reason is that while many bikes are equipped with headlights, taillights and reflectors, they aren’t very visible from the side – which means they can be clobbered at intersections or nicked from cars changing lanes without seeing them. Frier and Ota addressed that by installing RGB LEDs inside the rim of the wheels, and made them powered by a wheel dynamo that worked through pedaling. Not only are the lights visible from all sides, they respond to speed of motion, making the wheel lights change from white when at cruising speed to red when slowing down. The rim-mounted LEDs are self-powered (no batteries, motor or switches required), and can be seen from passing vehicles – a great safety idea for cyclists and a relief to motorists – plus they looked really sci-fi cool.
