I have a Cannondale Bugger clone, two wheeled , quite light, a very good trailer, just keep loads evenly distibuted and watch how much weight is bearing on the tongue of the trailer, especially where the trailer attaches to the rear of the bike frame. Mine attaches to the seatpost, as I find it more stable than my other two wheeled trailer that attaches to the rear stays. That one requires much more care in balancing the load.
