Contrails: DIY Bike Route
“Contrail” is a design concept that enables cyclists to increase their visibility to cars, pedestrians, and each other. Conceived by Pepin Gelardi and Teresa Herrmann, this frame-mounted device would allow cyclists to make their mark on the street with faint lines of chalk. The rear wheel spins a smooth trail of color onto the pavement as the bike whizzes along.
