I bought the bikelug one a couple of months ago and it's great. It folds up into the back of the Freelander and with three locking pins (one on the hinge of the bike channel, and one holding each of the wheel axles on) and it's all together. I also paid a bit extra for the double version, which can be used as both a single and a double bike trailer - single for my trackday bike and double for a couple of dirt bikes. Not sure if it would pull a couple of superbikes so you would have to check that. I think if you bargain hard enough you may even get a small discount. Folds up out of sight in the garage aswell. Good buy and recommended.
