Many times after a trackday I'm too worn out to unload my bike, or have to leave it overnight outside at a hotel. While the trailer hitch has a lock on it, it would be pretty easy to just unload the bike off the trailer to steal it. So I googled locking tie down straps and found Lockstraps.com. Pretty neat concept. The incorporate a steel cable down the inside of the strap, and a locking caribiner, to make the bike a bit more secure. I realize a cable could be cut with bolt cutters, but I still like the idea. I think I'm going to pick a set up, they're damn nice tie downs just by themselves. A little spendy at $40 a piece, but they seem really high quality. The only fault I see is the your canyon dancers could still be easily cut with a pocket knife. But I bet there's an easy solution for that.
