Developing Bicycle Communities

This concept created by Studio Gelardi, Contrail is a tool for developing bicycle communities. As you ride, contrail leaves a faint chalk line behind your bike. The goal is to encourage a new cycle of biking participation by allowing the biking community to leave a unique mark on the road and to reclaim this crucial shared space.
By using this device, bicyclists will have a clearer path on which to ride safely and out of the way of vehicular traffic.
