Anyone see this before? Just bought a pick-up truck and thinking about building this for it but thought I'd see if anyone knew about it first.
Pretty cool idea if it works.

Make your own Bike Rack

Thanks to Damon of Salt Lake City, who sent us the photos and instructions for this bike rack!
Fits in the back of your truck to carry three bikes in style.
Time needed = about 1 hour. Total Cost = Under $20.
Materials Needed:
30 feet 1" schedule 40 PVC pipe
18 connecting T’s
6 90-degree connectors (elbows)
PVC pipe cement
For a 4-bike rack, see the parts list and cutting instructions at the end of this article!
Cut PVC pipe to the following lengths: 6 – 18 ½”
6 – 16 ½” *
6 – 8 ½”
6 – 9 ½”
8 – 1 ¾”
*the 16-1/2 lengths fit a Ford F150 truck bed. You may need to vary this length for your particular truck. You can assemble it without gluing and then make adjustments.

Here's what all the pieces look like cut to length.

Assemble the frame as pictured at right. This is a view looking straight towards the wheel-slots. The horizontal pipe in the middle (seen behind the main assembly) receives the support struts. See the photos below.
Assemble the entire structure without gluing. This lets you adjust fit and set a correct angle for the elbows and Ts. Here we're assembling the main support frame. The two close pipes at the left of the photo form a slot, into which a bike wheel will slide. When complete, this part will be turned over so the Ts face down into the support struts.

Here the support struts are seen coming up into the support bar. Lying against the ground are the wheel-slots that will receive the bike tire. (In use, the structure will be turned over. The part that's sticking up here will be on the bottom of the truck bed.)

Glue joints one at a time, then let dry. In this photo, the support strut is ready to receive a T-connector.

Here the rack is complete, and has been turned over into its position of use. Drill a hole in the underside of the top connectors for bungee hooks (3 total). The bungee will hold the bike into the frame. Size the hole to fit hook style (plastic hooks work best.) An alternative is to wrap the bungee around the upper pipe and hook it back on itself.

  • <LI style="mso-list: l0 level1 lfo2; tab-stops: list .5in" class=MsoNormal>Glue connectors touching each other for standard mountain bike tires. Leave about ¼” space for 3” tires. <LI style="mso-list: l0 level1 lfo2; tab-stops: list .5in" class=MsoNormal>Use bungee cords to tie rack down to truck bed. <LI style="mso-list: l0 level1 lfo2; tab-stops: list .5in" class=MsoNormal>Hook bungee to seatpost or pedal to hold bike in place.
  • This design should clear an 8” rear brake rotor.

This design can be altered to make a 4-bike rack! Here's your parts list:
40 feet 1" PVC pipe
26 T-connectors
6 90-degree elbows
PVC cement
The cut pieces will be:
8 - 18.5 inch
9 - 9 3/8 inch (in place of 16.5)
8 - 8.5 inch
9 - 9.5 inch
12 - 1 3/4 inch
Follow the design above, but substitute the 9+3/8 pieces for the 16.5-inch lengths.​

And here's another take on the rack: Rick and Jeff Rodriguez sent these photos showing how they transport 5 bikes in their truck bed. They say the paint quickly gets scratched off. But consider paint if you plan to leave the rack in the sun -- PVC gets brittle and cracks after a year or two of sun exposure.

Here's the basic rack, painted and

ready to receive the bikes.
On the ground, bike tires fall into the

slots for a nice stable (cheap) rack.
For greater lateral stability, secure the
brace on top of the bed liner.

Here's another look at the bike rack with the brace sitting on the bed liner. A couple of tiny holes drilled in the liner can serve as anchors for zip-ties that lock the rack in place. In this truck, the front tires of the outside bikes sit partially on the tire well, raising them slightly. Having the rack oriented upward as shown still provides a solid hold.

OK, so now we've got three bikes. Raising

the outer bikes eliminates handlebar clash.
Now, let's add two more bikes. They

sit upside down and backwards.
Toss foam pads between the center bike and
the upside-down bikes so they don't bash.

Now toss a bungee or rope around the frames of your two upside-down bikes, so they won't tip outward against the outer forward-facing bikes. You're now ready to transport FIVE bikes to the trail in your pickup truck.

I've been using that bike rack for almost three years and it works like a champ. I did make changes to the original plans but that was because of my wife's recumbent trike.

Here is a photo of the rack in the back of my pick-up.

I had to make the offset to accommodate the wife's recumbent trike, since it had to go in rear wheel first and the derailleur would not go through the wheel slots. That caused me to offset the middle wheel slot, but I can still get three bikes in the rack with no problems.

Rather than use glue, I used sheet metal screws (one #8x3/4" at each joint) to hold the rack together. I did that for several reasons: 1) If I made a mistake, I could easily correct it. 2) It allowed me to assemble the rack and make sure it was level and squared before I screwed the joints together. 3) I could modify it to fit other vehicles by just changing out three pieces of PVC. My brother borrows the rack from time to time and his bed is narrower than mine. I have three pieces of PVC cut for his bed size and I just swap them out and it fits his truck like a glove. If you decide to screw it together, pre-drill the PVC so that it doesn't crack. Also, place the screws in the center or towards the inside of the connectors. Since I wasn't going to glue the PVC, I used a light coat of petroleum jelly in the connectors to make sliding the PVC pieces in and out a lot easier. After you have screwed it together, wipe the access jelly or grease.

Some other changes I made were the eyelets in-between the wheel slots to attach the bungee cords to. I used 3' rubber cords with the slots in them and I found that securing the bikes with the cords over the handlebars keeps them more secure than with the chords around the headtube. I also attached smaller bungee cords to the end eyelets to secure the rack to the front tie-downs of the truck bed. Also, I have widened the wheel slots slightly and wrapped some foam pipe insulation around the pieces that come into contact with the spokes. This will cushion the spokes and keep them from hitting against the harder PVC.

Since getting our Transit to haul the bikes with, I don't use the rack that much, but it stays in the back of the truck and still gets used when we each need a vehicle and I am hauling my bike.
