To connect the pedcab to tow bike’s hitch I created a simple coupler using a 1-1/4” EMT 90° elbow. I purchased a pre-bent 90° elbow because I did not have the means to manually bend 1-1/4” EMT tubing. [My pipe bender will bend only 1” EMT.] Also, as you will see later, the OD of 1-1/4” EMT slides nicely into the inside of a 1-1/2” EMT tube. In this way the pedicab is detachable from the hitch — for portability purposes.
