I transported the bike in a 5' x 8' U-Haul trailer yesterday and all went well. There was a wheel chock that came with the trailer as part of the rental. The wheel chock was portable and I did not secure it to the floor. I think that next time I would try and secure it because it did move a few inches to one side by the end of the trip.
I used some Erickson tie downs on the front, attached to some 'helper' ties (approx. 12 inches in length) that have loops around each end that I secured to the handle bar ends. I also used two tie downs on the back (secured to frame) for extra security (not sure if these were really necessary).
I had thought of running a 2"x4"' wood stud down each side of the bike along the floor and tight to the wheels and screwing these to the floor of the trailer with some wood screws but, with the wheel chock it wasn't an issue. I think it couldbe a good viable solution if I didn't have the use of a wheel chock...(keeping in mind that it is a rental trailer and that it would leave a couple of very small holes in the wooden deck).
