First post and all...but I have a $15 home made solution for pickup bed bike racks. Cut a 2x8 to fit in the grooves most trucks have in the sides of the beds these days. Mount an inexensive bolt down axle clamp on the top edge of the board. Drop the front wheel, clamp up the front end, rear end just sits free in my grooved bed with Line-X coating. Perfectly secure, no bike sliding around in the bed and takes seconds to clamp up.
When I need to use the bed for other stuff, I just lift out the board. Nothing is bolted to the truck.
