As I've mentioned before, it turns out that you can tow other bikes pretty easily with an Xtracycle. Here are a few more for the record:
I lent the Xtrakoram to theBicycle Federation of Wisconsin so they could show it off at an event (the Midwest Renewable Energy Fair, to be exact.) I had ridden the Cross Check to the bus station, and here the Xtrakoram tows it home.
I've been having some trouble with the Amsterdam, so here's the Big Dummy towing it to the shop for some warranty work.
and the Coop duh Gracie: The Big Dummy tows the Xtrakoram. How do you think it got to the bus station?
