I've moved to an from alaska 2 times now with bikes. If I am hauling a single bike I have rented the second smallest trailer and just towed it with my car. You can easily fit one bike, it's enclosed, and has tie downs. No problem. I did once transport 2 bikes along with all my furniture in a big ass uhaul. I loaded all the furniture toward the front and had my couch kind of sectioning off the last part of the uhaul. I ratchet tied down the couch like a bitch so nothing would slide back and also made a "web" above the couch in case any small items fell back. I then had both bikes side by side. I used tie downs for both bikes to the walls of the uhaul and none to the floor. I tied to the frames, wheels, handlebars, and every place I could. A frigging mess of ties, but they weren't moving anywhere. I also put some chocks under the wheels to prevent any rolling. I was sure to pop the door and check them every few hundred miles. Never had a problem in >2,500 miles one way. And that is on frigging bumpy ass frost heaven roads through the yukon territory.
