Building your own trailer should be easy on the pocket and easy on the planet. There are quite a few sites out there offering instructions on how to build your own bike trailer, often out of reused bike parts and often needing no welding.
The trailer above fulfills both criteria and the instructions are available via the Re-Cycle webite here>>
Additional comments on the same trailer are available here >>
DIY Longtail
Another diy project that needs no welding – this time a longtail cargo bike.
The full design/build process can be seen here. The designer then had a change of mind and decided to ditch the additional length. The new version can be seen here.
DIY Xtracycle
The pic above is one of many diy xtracycle styled cargo bikes featured on this thread from Bike Forums. Fascinating thread. Enjoy.
