That's good advice, sorry that happened to you, that really sucks. I can't imagine how awful that must have been to get where you're going and to walk behind your trailer and unload your Segway, and see that it's GONE!
OMG! That's terrible. You must have hit quite a bump or something for the segway to unseat like that. Are you 100% sure it wasn't stolen? Maybe at a rest stop? Here's a couple pics of my carrier, I just wanted you to see there is a 1" bar that secures it in place and is lockable. The guy I bought my 2 x2's from had it made (working tail lights too) because there was nothing like it available in the market. Maybe you can check into having a (lockable) bar welded onto your carrier. I am glad to hear to you did get a replacement, a great ending to the story.
