This Sunday at 3rd Ward, an artist collective workspace in Brooklyn:

Bamboo Bike Studio is partnering with Brooklyn-based design center 3rd Ward for the Green Bikes Birthday Block Party. The festivities will converge on Stagg Street in Bushwick, Brooklyn for bike competitions, bands and music videos, badminton, drinks, BBQ, live screen-printing and more. The Bamboo Bike Studio team and friends will be riding 10 deep to a Bamboo Bike Studio tent, where a live bike building demonstration will be going on throughout the day, and bicyclists can check out a bamboo bike, ask questions, and sign up for classes.

Sign up for a 3rd Ward membership and score a free bamboo bike, as well. Via Cool Hunting.
