This project was made for under 30 dollars using mostly found objects. If i had to buy everything i used it would cost around 60.
Step 1: Wheel Base
I have to confess i did not build mine. I got it from Dan who scavenged it from an broken trailer.
This instructable uses a firewood cart, i'm sure you can find other wheel bases to scavenge from.
Step 2: Making the Platform Part 1
3 - 30" 2x4s
6 long screws
Drill bits made for drilling metal.
Once you get those, drill holes into the wheel base, making about 6 holes to mount the 2x4s.
Step 3: Making the Platform Part 2
Once you have the holes drilled, mount the 2x4s onto the base making a nice platform.
Step 4: Trailer Hitch Part 1
To build the part that connects to your bicycle take a look at this instructable: No Weld Bike Trailer Hitch
For this step i used:
1 10ft x 1/2" conduit tubing
1 Air hose coupling
6 inches of webbed tubing.
2 hose clamps
Step 5: Trailer Hitch Part 2
This part was hard, i used rubbing alcohol to slip it on but it still took a lot of elbow grease.
After i got it together i ran a heat gun over it to seal it.
See the last picture for the hitch on the bicycle.
Step 6: Trailer Hitch Part 3
So i used a barrel! You want to have a sort of S shape going from the hitch to the trailer.
But if you have the money or can borrow one, i strongly suggest the conduit bender.
Step 7: Attaching the Hitch to the Platform
The conduit was a little too long, i cut off the extra with a dremel.
Step 8: Attaching a Base
I decided on a flat plank from some scrap wood i had lying around. I cut a 30x18 inch piece out.
Step 9: Painting It
Step 10: Test Ride
Right when i got outside someone yelled to me "I Want One!" which is always a great response to a new project.
I had someone sit on the trailer as i rode it around to test it out, the first time i went out i realized that my hitch wasn't tight enough. oops!
If you have ideas for improvements, please comment! Hope your bike trailer makings go wonderfully! Share your projects!
