Introduction: In Trunk Bike Rack

8/18/11 UPDATE:

Here is a short video of my bike rack : http://www.youtube.com/watch?v=3TSMnRLg9KY

I broke my rule of going the free route and purchased a real fork mount for $20 at my local bike store a few months back. You can see in the above photo how it sits now. Definitely a lot more sturdier. I'd recommend a fork mount or build something very similar to it!
So technically, to sum it all up (instead of going through the steps ahead) a 2x4 of your length, a fork mount (or something similarly built), and a few tools is all you'll need. Hope this has inspired you for ideas!




Ever since I got a new mountain bike not too long ago, I've really been wanting a bike rack for my SUV. I had one of those 'hang on the back door' kind of bike racks back then and I wasn't a big fan of it. I was always afraid and looking back to see if it was still there. Don't have a hitch so I couldn't get the bike rack hitches, obviously ;). I'm a real big fan of the roof racks. Gives the vehicle a great look in my opinion and it's just cool to see someone driving with a bike on their roof.
With those 2 facts being my only upside, I had to think of the down sides. Clearance issues, driving habits, the hassle of putting the bike up 6ft on the roof each and every time...just didn't seem too worth it.
So the only way I could be worry free, was by having it in the trunk! Without just tossing it back there of course ;)

*Note : I own a Ford Explorer. The width of where the wood fit was 52inches.

Step 1: Parts and Tools

I used a drill and a wrench.

The parts I used were all found in the garage.
-51inch 2X4 (trunk width measured to 52inches)
- A type of 90degree bracket (No clue as to what specific type it was to be honest. Been in the garage for years and I didn't even know.)
-3 washers
-2 nuts
-2 o-rings
-2 screws
-1 adjustable turner (not in this picture, sorry. If you click ahead you'll see it at the end of the bolt and realize what I'm talking about)
-1 bolt

*Note: This was per side.

Step 2: Position Where You Want the Fork Holders to Be

Once I gathered all the parts I needed, I took my bike and positioned the fork how I wanted it to be on the wood. I was going to line it up simply parallel to the edges of the wood, but as I moved it side to side, simulating a turn if you will, I felt that the parallel position might weaken the 90degree mount from the wood. So i positioned the fork diagonally and I like it. Felt a bit sturdier  as I moved it side to side slightly.

After marking where I wanted my 90degree brackets, I drilled in the screws to hold them in place.

Step 3: Place the Fork in the Holders

Once everything was set in place, I put the fork in between the o-rings. These moved around quite a bit for me. I knew ahead of time though because the bolt's diameter was way smaller than the bracket's diameter. Had to work with it though.

*Note: Those screws you see on top on the brackets serve no purpose. They were just one there when I found them and just kept them on.

Step 4: And Just to Make It More Secure

I drilled out two small holes then wrenched in those bolts you see there at the bottom of the wood. As you can see in the picture, they are there so I could secure the bike frame with a tie down just to be sure.

I took a test drive with it, and it held up very well for me. Checked up on it afterward and it lay just how I left it.

You know, this may not be top of the line, but I didn't spend any money making this, and best of all I felt great after it was complete!

Enjoy!

Step 5: And If This Has Inspired You to Make Your Own...

Lets see it! Post a picture as a comment in this step!
Maybe it will help others and myself for some great ideas ;)

Just wanted to say "YOU HAD A VERY GOOD IDEA!!!" I made one for my minivan and it hold my Diamondback 26" and my kids Mongoose bicycles as well i made mine out of stainless steel angle.anyways Thanks for the idea.Was wondering do you have any ideas for making a small tool box to put under my seat let me know.

Just curious, but would it have been easier to use a prefabbed bike mount over all these little parts? and if going this route would it have been better to use a sleeve over the bolt where it meets the dropouts(to keep from possibly damaging the dropouts)? Other than that nice design. I've been looking to build something like this for my van..

I wouldn't really say "easier" but rather less time consuming for going the prefabbed route. I found one for $20 at my local bike shop and was about to buy it. You've probably seen one and know what I'm talking about, but just to say, it's pretty much like putting the wheel on the dropouts. It's a bolt on object with the dropout tightener using the actual pieces to open and close the wheel to keep it tight.

I could have very well gotten it, but I decided to go for a free route on this one. These parts were lying around my garage so I just decided to go from there. Took a few to figure out what I needed and how to go about it. And I'm sure if you bought parts you'd need from Lowe's or Home Depot, it would still probably be cheaper than buying the actual prefabbed mount.

And yeah, you could put some type of sleeve over the bolt. Maybe just wrap it in tape to keep it simple. In fact you don't even have to use a bolt if you didn't want too. Home Depot has those metal rods, about 3 meters, and I'm considering trying that out.

I've always wondered why people drive 30 miles to bike for 4. Then one mystical day, a problem arose. Since parking is at a premium at my college campus and I'm not willing to walk 4+ miles a day I decided to take a bike.

Not being able to fit a bicycle in my Civic, I found a better way. Get a smaller bike.

14" tires FTW, and it was on it's way to the dump.

Fits perfectly in my trunk without too much 'slop'. With my backpack there is no slop.

 Nice. I had the same problem but tackled it a different way--I bought a Montague Paratrooper bike. It folds up and easily plops into the back of my car. Obviously, your solution is less expensive.

Is the wood secured to the trunk some how or is it just wedged in place?

author
rymagahis (author)RadBear2010-02-26

It's actually just wedged in there. The left side has little movement back and fourth, maybe about an inch (looking at the 3rd picture on step 4). The right side though, has about 6-8inches of back and fourth movement.
It doesn't move though. Having the carpet really helps.
I suppose a person could just place something simple in between if they wanted to be sure.
