As with all good instructables, this one was born out of necessity.  I needed to get a bunch of stuff from point A to point B. 

I am a scavenger so I needed a bike and trailer to get me around to garage sales, curb alerts, landfills, dumpsters, etc.  Growing up, I was taught to never let anything go to waste.  It's kind of my life's ambition to reclaim, re-purpose, and reuse.  We live in a culture of waste, where all goods have become disposable.  If you take anything from this instructable, I hope it's an inspiration to think twice before you throw something useful away.  I built this entire bike trailer, beautiful and functional as it is, at zero cost entirely from other peoples' trash!

Since Instructables is already inundated with bike trailer tuts, I wouldn't have created this one if I didn't think it was simply better than all the others.  In addition to being free, eco-friendly, strong, sturdy, and nimble it was exceedingly simple and quick to make.  It required no welding, grinding, sawing, or drilling and took a total of 4 hours of planning and construction!  Let me show you how I did it...

Step 1: Gather Materials

This bike trailer was built primarily from two things:

1.  A steel framed "Big Wheel" type tricycle
2.  An old 10 speed mountain bike

The tools you'll need are very common:

1.  Socket or wrench set
2.  Allen Key set
3.  Pipe wrench
4.  Screwdriver
5.  Pliers

The specific make and model of the trike is a "Micro, Spinmove."  Though I don't think its necessary that you track down this exact trike for your own bike trailer, I have to say this one worked out perfectly.

Because the old 10 speed was a junker, it took some extra elbow grease to crack through the layers of rust a grime. However, I'd rather take more time and effort parting out a nonfunctioning bike than dismantle a perfectly good bike.  Which leads me to our next step...disassembly.
<p>been thinking on how to use those thrown away jogging strollers as a cargo trailer/ balancing 'training' wheels for older folks who don't balance so well . This gives some good ideas . !</p>
I used a trike that had a different setup not helping but I used a few other small bike for the side wheels. By the way I like the idea of having the bike fork at the front so it can turn and not have the connection at the seat post. THX FOR THE IDEA
<p>good job I love it making one for my self as well</p>
<p>holy cow! I have a old bike and a metal bigwheel just sitting in a garage! I am looking all over for a bike cargo trailer at pawn stores , on line ect. I just have to hoof it over there to pick them up. thanks! ps your youtube video is gone.</p>
<p>Marvelous inspiration...<br>Thank you </p>
<p>This is awesome! I'm totally going to build this!</p>
<p>Awesome! Good Instructable! For quite some time I have been looking in to building me one of these trailers for a beach cruiser that I have. I just had not found a good design or an already built bicycle trailer that I liked. Your design looks not only simple and feasible, but perhaps the most sturdiest of them all that I've viewed. May I ask, how is the handling of the trailer? How is it on turns, how is it for you when pedaling and towing it, etc.? Thank you once more!</p>
I'm wanting to convert an adult trike into a trailer myself. I've considered attaching the front forks onto my rear forks of my 18 speed, but my concern is in the turn radius. When I'm cruising along, I lean my bike sometimes in the turns. How will this affect the trailer? The adult bike has no leaning ability, and I imagine your trailer doesn't lean neither. Perhaps if there was a pivot point at the housing of the front forks? I'll have to experiment. Nice instructable!
I would love to make this, but not a huge fan of the permanent look. wish that i had a welder, instead of the fork, I would have a flat surface with a couple of holes in it to attach to a bike rack that way you can pop in a couple of pins to hold it in place, but other than that, awesome build, looks pro :D
Of all the bike trailer designs i have seen on this site yours is the best. Great job.
I've recently built one out of recycled steel box section. It doesn't look half as good as thism, probably the best looking trailer i have seen !
Awsome! I have been needing to make a bike trailer for some time, but I would rather not use a frame from a big wheel. Though after reading this I did get an idea on how to modify the design to suit my needs. Thanks! <br>
The &quot;Big Wheel&quot; or Drift Trike Frame is worth like $50 over here in NZ
Very nice! I was especially interested in how you attached the bike wheels to the trailer, since I have been saving some salvaged wheels for the purpose of making a cart or trailer.
nice job !
It looks to me that you miss one angle freedom. When you tilt your bicycle to 60 degrees (for example), doesn't one of trailer wheels go up? <br>When trailer is loaded this can cause problems with riding.
When I'm riding, my bike is generally between 80 and 90 degrees with the pavement in either direction. The pivot of the fork will allow for this. <br> <br>You're right about tipping the bike at 60 degrees; a wheel will lift off the ground. However, if your bike is at 60 or 70 degrees with the ground you're already falling. If anything, the trailer makes you safer because it prevents this from happening. <br> <br>
60 degrees was just an axample :) <br>I'm glad it's not a problem wnen riding. <br> <br>Congratulations on great DIY!
I like everything, except the cleats. That little screw (forst photo in step 5) looks too weak for the work to be done. And the hole for it is located too near the edge of rear forks. <br> <br>Fixig that, it is for me a good idea.
I'll give you that. The original plan was to mount the trailer fork drop outs right onto the rear wheel hub, but the skewer was too short. If the screws ever became a problem, I'd find a longer skewer.
