Connector of ZiZZO TRAILER

I've been enjoying my ZiZZO trailer for over a year now with my 18-speed cross bike. I recently added an e-bike to my fleet. It has a built-in rear rack, so I couldn't mount the trailer hitch to my seat post. I came up with an adapter and extra hitch so I can use the trailer with both my bikes! Hitch: Solid construction. Delivered with washers and thumb screw installed backward. Easy fix.
