Awesome Bike Trailer




I'm a passionate maker and video creator on YouTube!

I made this super awesome bike trailer to do shopping, buy and transport trees and plants, get lumber....etc.
It's lightweight, takes over 200 lbs of load, versatile, maneuverable, ecologic and the best of all - cheap to make!

Make it and you'll love it, guaranteed!

Step 1: Cutting the Stock

Cut Red Cedar boards to length and width on the table saw and miter saw.
Then dry assembled everything.

Step 2: Joining the Frame

Join the frame of the trailer with 4 inch hex screws and glue.
Use clamps and wooden spacer for same measures on both sides of the frame.

Step 3: Making the Box

I made the box out of Guanacaste wood (rot resistant) but you can use any type, just protect the wood accordingly.

I used pocket holes to make the box sitting on top of the frame.

Then I joined the boards using pocket screws and glue for the sides and bottom.
I also added some screws from the outside for added strength.

Use the jigsaw to cut handle holes on both sides.

Sealer was applied and I used projector to trace the Aztecan pattern onto the box.

Later my wife painted the tracings with black acrylic paint.
When it was dried I put on 2 coats of lacquer with sanding between the 2 coats.

Step 4: Metal Parts

I had to make some metal parts to attach wheels and to attach the trailer to bike's rear axis.

I made 4 pieces for wheels, and 3 pieces for the mechanical connection.

File the sharp edges, sand and then paint all (I painted mine the bike's color)

Mechanical parts were assembled as shown in the last picture.

Step 5: Finishing the Frame

Make the cross part out of Oak (or any hardwood) for connection to the rear axis of the bike.
Drill the vertical hole for the bolt and wing nut that attach the trailer to the mechanical parts.

Add two 45 degree bars for added strength and to unify the frame.

When it is all done sand everything and put sealer and two coats of lacquer,

again sanding between the coats.

Step 6: Putting Everything in Place

Install metal braces and then attach wheels to them.

Then attach the trailer to the mechanical parts.

When trailer is not in use the mechanical parts swing freely

so there is potential danger of them catching up with chain

or spikes. There use rare Earth magnet to hold the pieces from swinging.

Attach the finished box with four screws from the inside onto the wooden frame.

Finally as a nice detail I installed a ''car'' plate.

    This is almost identical to the design I came up with for my bike trailer. I had a problem with my metal wheel holders though as they were just pieces of flat bar with three holes and a slot drilled in them which were then screwed onto the frame. The problem is they suffered from some vibration issues which cause the screws to mar the holes wider until they popped right out. I was considering using bolts to repair it instead of screws. But I think I'll try your design for the wheel holders, it seems the extra size and the fact that it bends around the corner of the frame secures it better and distributes the forces nicer so you don't get that marring.

    May also be the wood I used too (spruce vs cedar).

    I've had similar trailer for the last 2 years. This one I made the base from cedar instead pine, everything else is the same as the previous one.
    Although cedar is impervious to weather better than pine I still recommend pine as better choice (rigidity) if you store your trailer under roof (great choices would be Teak, W.Oak, Mahogany)
    Metal pieces work great the way they are bent and made, last ones I bolted and these are screwed, I see no difference in performance.

    The most Important part to reduce drag and vibrations is that the frame is square AND that the tires run parallel to each other.

    I've been looking at bike trailer projects for ages & they're all metal or plastic. This happens to come along in my related articles and I just happen to have the timber from a single bed frame and the wheels from a 20" bike sitting idle... yes, I do believe you've solved my design struggles. With no car and only 2 baskets on the bike, shopping's a pain. This will make life so much easier.

    I'm so glad to be able to help, I hope that when you build it you post a picture of it here on Instructables to share it with us! You'll love your trailer! Cheers

    That wood trailer is beautiful, but I don't think it's very practical in the long run nor is wood the best weight-versus-strength choice of materials that are available. How could this design be translated to something more practical, perhaps starting with a PVC frame?

    Thank you, I have been using my past one for two years (I built an new one just to show my subscribers on YT) and it is VERY practical. It supports over 200 lbs and anyways you can't haul more than that (unless you're Hulk). Still, better version would be to make it from aluminum, but that would be more costly and wouldn't have the charm of wood! Cheers!

    I used 1'' cedar for the frame and 3/8'' Guanacaste for the box, these species are very good and excellent rot resistant woods - so great choice in wet weather. In fact so good that probably my zinc hex screws will probably rust before the wood rots, which I don't have to worry because I live in dry and sunny Mexico :)

    Hi Andrea,

    Wonderful work ! I am planning a bike trailer build myself. I live in Paris (France) and I think it's hard to get some red cedar and Guanacaste wood.

    I read you also use pine wood for the frame, but for the bos, is an other alternative for Guanacaste wood ?

    Could you telle me the dimensions of the trailer and the box ?


    Sorry for my english.

    Thank you, Sir!
    You can use any wood for the whole trailer as long as you put on adequate protection, oak would be nice (but it's heavy)
    Some woods are more rot resistant than the others but pine (widely available) should serve you just fine!

    The trailer dimensions: base 70x70cm (square) and the box is L70 W45 H40.
    For the base use at least 2 cm thick material and for the box you can go as thin as you want to (mine is 1 cm thick material).

    I've seen a lot of mods to child bike trailers to turn them into light weight multi-use trailers that aren't hard to do. You could look at those and get one off of craigslist.

    As long as wood is not trapped in the wet and allowed to dry regularly, it should last.


    it's hard for me to imagine a better material...... we've used it to build everything from boats to airplanes to chests to bowls and plates. if those dont cant deal with stress and abuse, and weather, then nothing can.... properly sealed or painted, it'll last ages.

    i also find it hard to imagine pvc being a very GOOD material.... it's brittle, especially when you leave it in the sun or freeze it, and i cant see it holding up very well to a bumpy road....

    PVC and sunlight are not such a good mix. If the builder used PVC he would then have to coat it with materials to protect it from sunlight increasing the use of materials and labor. Electro-mechanical tubing is the choice of many builders. Much depends on local conditions. Weight is a huge issue for long distances or areas with hills. In this build appearance was super important and the build looks really nice.

    I don't have any idea why these days people (like you) put up these comments that ironically suggest 9/11 tragedy.
    Please stop insulting people and families that lost their loved ones. (and it doesn't matter what caused 9/11, many died on that horrible day).
