the bicycle as a cargo carrying transportation device in the urban landscape of New York
City. Implemented in order to meet the local transportation needs of the Ditmas Park
CSA and Compost for Brooklyn, the CSA / Compost Bike Trailer ultimately seeks to
connect and build relationships between environmentally minded groups and individuals
in the Brooklyn neighborhood of Ditmas Park by helping them work together to make our
food cycle healthier and more sustainable.
The final iteration of the CSA / Compost Bike Trailer meets the needs of all
programmatic elements required by the Ditmas Park community groups involved
and ultimately is designed to be reconstructed many times over by groups in other
neighborhoods with similar needs. To pursue this goal a detailed set of free construction
documents has been made available online and all materials used to make the bike trailer
are easily and inexpensively accessible at local hardware stores. It is our hope that the
CSA / Compost Bike Trailer will ultimately connect people within the communities
it functions within, promoting a healthier food cycle and the bicycle as a viable cargo
carrying transportation device in the urban city environment.

Step 1: Schematics & Shopping List
Step 2: Assemble Top of the Trailer (part 1)
Cut the plywood to appropriate size and drill 6 holes on each side for the threaded rod. The way we measured everything out is by placing the milk crates on the plywood, spacing them out the way we wanted them and marking the spots to drill.
Then cut 2" by 2" into appropriate chunks and drill holes at the ends. We have 2 long ones going parallel to the plywood, then shorter ones perpendicular (so they hold the buckets in place).
Then even shorter ones on the top of threaded rods which will later hold the crates.
Step 3: Assemble Top of the Trailer (part 2)
Use gorilla glue (or some other type of wood glue) to place medium length wood on top of the short chunks of wood that sit on the ends of the threaded rod. You could screw them in but these things are there only to prevent the crates from sliding back and forth.
Step 4: Paint the Top of the Trailer
Step 5: Bend the Conduit
Step 6: Bolt on the Parallel Metal Beam
Step 7: Attach Conduit
Step 8: Bolt on the Axels
Step 9: Put in Pins to Hold the Wheels
Step 10: Assemble the Hitch
Plug the end of the conduit with a cork or a sliced up piece of hose you got. The bolt that is going to go through the conduit is going to help prevent it from going all the way in.
Then wrap a 2 foot long piece of hose around your seat post and bolt it to the end of the conduit.
