Hi, everybody! I'm a longtime mechanical tinkerer with cars and anything that ticks, I'm working on converting an early 60's Columbia tandem to a longtail cargo bike to use on Cape Cod rail trails to the beach. I'm sure its been done, anybody have examples of theirs? I'm starting with moving the rear crankset to the front and leaving the rear crank empty, any issues with one really long chain? I assume I'll need to replace the tensioner and keep it good and tight. Any tips or lessons learned would be appreciated.
