Pedal Express, a bicycle delivery company in Berkeley, Calif., has teamed up with a local nonprofit youth group to run a program that delivers fresh organic produce to Berkeley residents. Teenagers in Berkeley Youth Alternatives work part-time growing veggies on a half-acre community garden, earning money and school credit. Once a week, the produce is carted to customers on cargo bikes, tricycles with flatbeds that can carry up to 800 pounds. Customers rave about both the tasty food and the theory behind the program. “We’re really getting people to rethink living in this area,” said Pedal Express founder David Cohen, who several years ago helped organize the Critical Mass bimonthly bike rides through San Francisco streets to promote alternative transportation.
