Bike and Quad Trailer Build

After riding this last weekend and hauling 3 bikes down on Grant's trailer, I decided I needed one. It's so nice to not have to load and unload your bed of bikes and gear. Especially when there's 2 or more bikes. I didn't give much thought to it before I started other than asking Grant his dimensions. All I knew is I wanted one and about the size I needed.

I made the entire frame out of 2x2, 1/8" wall tube. I decided that 5'x8' was the size that would for sure be big enough for 3 bikes but it could also fit 2 quads. Here is what I started with.

After I had the main frame I decided that 2 cross members would be sufficient for the load I would be carrying.
Then I started on the tongue. I measured my truck from the hitch to the corner of the truck. I wanted to be able to jack knife the trailer if I need to so I made the tongue long enough to do that. I then did 2 big angle gussets to give strength and this area will probably also serve as storage eventually. I will also end up running a second tongue under the first and tie it into the first cross member to give the tongue more strength and rigidity.

Up until this point I had about 2.5 hours into it. I have Henderson trailer in Orem a call to see if they had the axle I needed in stock. They did. I picked up a 72" hub to hub 2000 lb 5x4.5 axle. I only called to see if they had it. But when I got there to pick it up the guys already had it pulled as well as all of the hubs, nuts, bolts, shackles, springs and everything else I needed. These guys always help me out with trailer needs so I'd recommend them to anyone. I also picked up a coupler which slides over my 2" tongue and fits a 2" ball.

It's been a while since I put a trailer axle hub together. After I did the one side I started on the other and realized I left out the axle seal on the first hub. I had to pull it all back apart, grease and all, to make sure it was done right. I set my axle 2/3 back on the trailer with my shackles at about 11 degrees. Then I welded up the coupler. I found an old spare trailer tire and wheel up on the shelf and it happened to be 5x4.5. So I slid it on to get an idea of ride height. I like it.

I will ill be putting 1.5" angle around the edge of the frame to protect the corners of the wood deck. I will probably use 2x8's. Not sure how I will fasten them down yet though. Maybe carriage bolts, maybe weld a strip of metal over then ends of the boards and just do a couple bolts and maybe a strip or 2 across the middle with just a couple bolts. Then I will work on the wiring and the chains. Then it'll be complete.

If anyone has some 14" trailer wheels that are 5x4.5 and good tires I'd be interested.

Looks good, even when tilting my head ;)

And yes, Henderson is AWESOME. They have everything cool, and usually in stock.

I hadn't even headed to get metal yet when you came by. Had to drop off the jeep at six states first then headed to Lehi.

I picked up some of the prebent almost 1/4" tie downs from metal mart. They are plenty big to get one or even 2 of my hooks through. They will be welded to the side of the frame closer to the top.

Looks fun. I have built a handful of my own trailers and learn a little more each time. I have a trailer fetish, so it's double fun to fab and get a trailer out if it!

Yes you gave me the idea, along with Grant's trailer. But mine looks totally different than yours. Thanks for all the help along the way.

You too Cheston!

Pretty much. I leveled all the pieces with the jack stands and before I finish welded everything I pulled corner to corner to make sure it was square. It was only out of square a quarter inch from when I eye balled it. I tapped them to where they needed to go and welded it up. I honestly think the wood deck will take longer than the metal part.

Got quite a bit done today. I got off work a little early and was slated to watch my boy while my wife went in to work. He ended up going down for a nap pretty soon after I got home though so I was able to work in the garage. I didn't get many pictures as I went this time. I started out by flipping the trailer over and welding on the brace for the tongue that extends back to the first crossmember. It stiffened it up quite a bit. After that I got my chains hoops welded up. After I got the first one on I realized I didn't slip the chain on it before hand. So I had to cut it off, grind it down and start over. Then I cut and welded on the 1 1/2" angle on the front and rear of the frame. The deck sits inside of that. After that I welded on the front 3 tie down hoops.

By this time my boy was waking up so we went and picked up some wheels and tires from a local used tire guy. He had just had the wheels redone and the tires are near new and match. From there we went and picked up the 2x8's for the deck and some fenders from Henderson trailer supply.

We came home and got to work on the fenders. After about an hour of working on the fenders and supports I fit them over the tire and they're not even close to fitting. I fit them before I did any cutting or welding but I must have looked at something the wrong way. I don't know what is going on with them. I gave up on them and maybe I'll get to them later.
Then I got the 2x8's cut to length and got them all laid out. Then I drilled 2 holes per board on each end through the lumber, angle, and 2x2 tube. I used carriage bolts all around to fasten them.

It's pretty fun as a dad when your little boy can start to help you out in the garage. He's barely 2 but I would drill the holes and then he would blow all the metal and wood shavings off the hole and then put the washer and bolt in the hole. I only had to show him how to do one and he picked it up. A few times he couldn't get the bolt to seat all the way so he would sit there and hit it with his fist until it went in. I've got a future fabricator on my hands. :D

Shortly after we got all the bolts in the wife got home so she got to cooking with my son and I tightened all the bolts down. Welded on 4 more tie down hoops, cleaned up the garage and took it for a drive. I'm happy with it. It is pretty dang light. You can't tell your pulling anything (at least not in a 5.7 Tundra), it is just wide enough to know its there and see it back up, and it sits level with my truck. When I got back I loaded up the bike to make room in the garage and it fits great. I can park my truck on the left side, the trailer with the bike on the right and the mini behind the trailer. All I've got left is the wiring, the jack if i decide to do one, and the stupid fenders (if I put them on).

Nicely done !

Now time for some stake pockets for the side rails when hauling trash or branches or other junk
And a tongue jack maybe.

Great work! My .02, I think you should make at least a front rail to hold the bike as opposed to the rear strap. I had a real similar trailer and once dumped a bike off the front, and once a quad due to rear strap failure.

I plan on doing something in the front. Not sure what yet. I was just strapping it up to get it out of the way. That would definitely suck to lose a bike off the front.

That should work!

My $.02, add some carriage bolts to those boards. I'd do them at each crossmember in addition to what you already have, it'll help keep the wood from warping/twisting over time. I just re-decked my car hauler last fall, so the memory is fresh in my mind. ;)

Looks good. I love having a trailer over using my ramp or my hitch carrier. My $.02 :D Do the fenders, without, even on dry road, your bike ends up with crap all over it. I took my fenders off because they were falling apart and it drives me nuts how much crap gets on my bike without them. I'd bolt them on vs. welding them on because they will get stepped on, hit, bent, broke and it's a lot easier to replace them when you can simply unbolt them and bolt some new ones on. Also, skip the jack. The trailer is small and light enough that it won't really buy you much. You can back-up to the general location and just drag it to your truck...even with a bike on it. I can do that with three bikes on my trailer.

What do bolt on fenders look like and where can I get some. I already cut and welded the ones I have to mounts but they're not going to work. Maybe on the next build. But I'd definitely be interested in bolt ons.
