Following up on
this thread from September, I bought a bike on the way home from work today and towed it home.
In the original thread, I speculated that mounting
one of these to my rack would work. Thinking it through, that could damage the fork dropouts. The reason is that it's meant to clamp the forks tightly in a roof or pick-up truck rack where the bike isn't moving, relative to the object it's attached to. Using it as a tow hitch wouldn't let the bikes pivot up and down over bumps. This would put stress on the dropouts and probably wouldn't make for a good ride either.
But the idea was close enough, that I worked something else out.
I removed the front wheel and attached it to my backpack using the load compression straps. Next, I rested the towed bike's fork dropouts on a crossbar on my rack. The fit was perfect. Then I bungeed the towed bike's downtube to the back of the rack--tight enough to keep it there, yet with enough "give" for over the bumps.
It rode marvelously. It was as if it wasn't there at all. I could have ridden miles and miles that way.
And the looks I got from cagers were entertaining.
