I was looking for a heavy duty rack for the back of my bike but either I couldn't find one or the one I found was too expensive. So, I decided to make my own out of 1/2" electrical conduit and some wood.

It's surprisingly simple and can hold the weight of a person. Plus, since the top is made of wood, I can screw anything I want to it. I'll keep refining it and maybe offer it for sale to you guys for a modest price.

Step 1: Measure and Cut Conduit

You'll have do some basic measurements here from under you seat to where the tire ends, say 24". The rack should be level with the ground. I cut 2 pieces 24" long and used my bench vice to flatten the ends. I bent them to so they would fit on the bolt that tightens the seat.

Step 2: Cut the Wood

The wood needs to be about 18" by 6". Sand the edges smooth and pait if you like. Like I said earlier, you can screw a milk crate or other container to the wood pretty easily.

Step 3: Drill the Holes

Here's where you have to be patient and take your time. I drilled 2 1/4" holes through the conduit and the wood.Make sure the wood is thick enough to do this. I drilled a hole from each side of the wood to meet in the middle and used a small rat tail file to sand the inside hole.

Step 4: Cut the Theaded Rod

I couldn't find 1/4" bolts long enough so I used 1/4" threaded rod with nuts on both ends. Make sure that you cut the rod long enough to bolt up the uprights.

Step 5: Add the Upright Supports

The final step involves cutting supports that go from the rear axle to the rack and attach to the rear threaded rod. You'll have to measure carefully to get the rack level. I attached the rack first and then measured the uprights.
