Yes, the rack just sits in the bed. It provides a very stable platform so the bike is up right, not resting on the frame or pedals etc. and it is very stable from tipping over.Are you just sitting the rack in the bed of the truck? If so, how is that any different from just standing the bike up in the bed, with no rack?
If you just just stand the bike up in the bed, whats to keep it from tipping over on every turn?
