How to make a cargo trailer? This page is for a general answer and it consists of at least two main parts: personal experience and technical part. The technical parts are perhaps the two hardest parts.

Has anyone attempted to make a cargo trailer for their bike? How did you do it?  How has it worked? How long did it take? Would you do it again?  

Technical parts with their own separate questions


How can you make a trailer hitch between a bike and trailer?
How can you attach/mount a wheel onto a trailer?
I've made several and documented at least some of them:


2 wheel trailer 1.6x1m: http://www.moz.geek.nz/mozbike/build/megatrailer





2 wheel trailer 0.8x0.4m: http://www.moz.geek.nz/mozbike/build/shoptrailer





12 more of the above with a better design


 


a four wheel, inertia braked trailer


 




2 wheel, single sided wheel mount trailer with telescoping drawbar


I much favour the mass produced design because it's easy to weld or braze together and quite robust. The chain-in-spring hitch is reliable and durable and very hard to break (the chain links eventually wear though but that takes years).
