I have used a Tow-ster, It's the best devise for towing bikes I've ever used.To
me it pulls and backs up like a trailer.The so called outriggers are low enough
to go under the bumper of the tow vehicle when backing up or making turns. I
also have been hold that towing some bikes long distances with the rear wheel on
the ground may damage the bike, but shorter distances as in emergency
circumstances it's not a problem. Still I would check with a dealer or mechanic
if not sure.
One can always disconnect the chain,belt or shaft if necessary!
