Approximate cost was $20 - w/o paint $10.
Pipe Cutter (I used a chop saw)
(3) 10' 3/4" PCV
(6) 3/4" elbows
(10) 3/4" T's
PVC Cement (use in a well ventilated area)
Truck Liner Paint (Found in the automotive section, not the household or home paints)
You'll want to cut from your PVC pipe the following lengths:
You should now have all the items to assemble. It should look like the second picture.
Sand any rough edges so the pieces will slide together well. I would suggest a test fit. Make sure it fits in your truck bed correctly. Also make sure your bike fits in the slots created. Once everything is fitted properly, get that pvc cement out and go for it!
You may need to carry more than two bikes. If so you will need to add a few more T's and another section of PCV pipe to your shopping list. Also, I use a couple bungee cords to anchor down my front tires, they really don't move but I don't like to have to worry about it either. This should go without saying but, I wouldn't trust locking your bike to this alone. It's sturdy and unless someone happens to have pipe cutters it would be difficult for them to run off with it, but you never know! I secure mine with a steel cable and padlocked to the truck bed.
Hope this helps anyone looking to save a few bucks and have fun doing it yourself.
