One-wheel trailer
 

I have just dug up the only digital image (scanned) of the rig that carried my then girlfriend and me around the Indian subcontinent and then to and around Europe. I thought I'd post it here for your amusement:

The bike was a Honda CX500B that was still running great with 180000 km on the clock. The trailer was built from the rear end of a farm bike. Coupling was a reconditioned universal joint from a tractor's PTO. The plastic container was our automatic washing machine.

Nice picture but very very big.
Maybe a 640x480 format do the job too.

A few years ago. in a Dutch bike magazine (I think it was Moto73) was a story about a Dutch couple driving RTW on an old CX500. They bought a sailing boat for the oceantrip to the US and had the bike, in parts in the bow of the ship.
