I have a trunk mounted rack-
It's by Yakima...
but I was able to get a cool little cable lock device for it that actually locks the rack onto the back of the van - or the trunk.
It's better than no lock at all!


Otherwise- I festoon my bikes with locks- heavy duty- and I mean HEAVY DUTY shackle locks ( U lock- whatever) lock the front wheel to the frame. Then a super thick 6 foot Kryptonite lock figure 8's through the frame and wheels.

I figure they'll look to the unlocked bikes first.
