I take 2 MTBs when we go camping, mounted on a trunk rack on the rear of my VW Vanagon. In the past, I've run a long cable lock to the tow loops on the car, but it's not the most secure. And we'll often leave the bikes all day when we go hiking.
Is there a better method? I suppose I could take the bikes off the rack, but there's not always a place to lock them, especially at trailheads. Ideas?
Thanks.
