Ok... It was requested that I put these pictures in this post, too, so here ya go!
Towed my wife's new bike home... 20 miles!
got lots of looks, comments, double takes, pointing, etc...
Even someone calling me a jerk for hogging two bikes and not giving him one! *laughs*
I use bailing wire to attach a hub to the rack... I think it would have worked better with my other rack, as it had more tie-down points... I used two cargo straps to the handle bars to stabilize it some more and keep some stress off the bailing wire. The front tire is strapped to the side of the towed bike using my bike lock. Also put a loop of tie wire around the tire and pedal to keep the pedal from rotating and hitting my back tire.
It handled fairly well, but let the bike move a little too much side to side, so after 20 miles I was pretty tired... I think it would have been better to tie the hub down to a section of 2x4 and tie that down to the rack. But all-in-all it worked very well, including dropping off a couple curbs and cutting across the grass in a couple places.
