Contrail

Developed by Brooklyn-based Studio Gelardi, Contrail was a finalist in last year's Design21 "Power to the Pedal" Design Competition.

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.
