Firstly I would like to say that I don’t know who this person is or where the photo was taken (I came across it here), but I thought this was so impressive that I’d pass it along. The guy is riding a Mundo, pulling a fully-loaded 8ft trailer (looks like a bikes-at-work trailer), with another trailer/bike attached at the rear end (but oddly doesn’t have anything loaded on the Mundo itself). Impressive none-the-less.

wow… I'd like to know how he attached the trailer to the mundo!? I've been trying to figure out how to do that myself!
I agree Tim…still trying to figure out how to attach a trailer…I'll get it eventually.
See this blogpost on how to attach a trailer (via Weber-Hitch or other one-sided attachment, like for example Joe's trailer) to the back of the Mundo. Works fine for me!http://yuba-mundo.blogspot.com/2010/04/anhangerkupplung.html
This is a "Rock the Bike" related rider, as he is towing their "Fender Blender" on the back, and that trailer is actually a portable pedal-powered generator for music performances, called "The Biker Bar". Several cyclists can pedal at the same time and generate power for a full on electrically amplified performance.
Max…thanks for the info. It's a pretty cool set up.Stefan…thanks for the link to the pic. I'll probably do something similar, though my hitch is a bit different than the one in the photo.
