Article Summary

When it comes to riding in the city, you'd be forgiven for thinking that cyclists don a cloak of invisibility before entering a busy traffic stream. According to the latest figures from the U.S. National Highway Traffic Safety Administration, 618 cyclists were killed in motor vehicle traffic crashes during 2010 and a further 52,000 suffered non-fatal injuries. While this loss of life only represents two percent of all motor vehicle traffic fatalities, it's still troublingly high. After reading about some well-publicized urban bike/truck battles where the commercial vehicle emerged a good deal better off than the rider, designer Tory Orzeck started to think of ways to give cyclists more presence on the road. The result of his labors is a handlebar-mounted, dual-tone, LED-packing smart bike horn called ORP.
