Build a Bicycle Cargo Trailer

Bicycle cargo trailer 

Have you ever wanted to take something extra with you when you ride your bike, but didn't know how you could get it on the bike and still be able to ride? I have, and believe me one of my favorite challenges about bike riding is figuring out how to strap anything from a tennis racket to a load of firewood to a bike. There is something about that moment when you wrap that bungee cord around your item just right, pull on it until your fingers hurt, and get it to hook on. You step back and think to yourself, "This is rigged but it just might stay on."

In my effort to carry more things with my bike, I decided to build a cargo trailer. It wasn't going to be a typical trailer, though. I wanted something that was heavy-duty, maybe something that could handle most household appliances. I got started just like with every other good homemade bicycle cargo trailer — with a pair of garbage-picked wheels and a set of tires that were given to me for free.

Here is a quick rundown of the main features of the cargo bike trailer:

  • Large 28-by-41-inch deck
  • Mounts to any bike rack with a quick-release ball joint
  • 1-inch square steel tube frame can accommodate up to 700-centimeter/29-inch wheels and tires
  • 100-millimeter dropout spacing to allow for most bicycle front wheels
  • Space for toolbox with tools, straps, and bungee cords
  • Adjustable pulling arm to allow mounting to any bike

My main motivation for building this DIY cargo bike came from many bike-move videos and blog posts on this topic. A bike move is just what it sounds like — moving to a new house using only bikes for transportation and hauling. This requires cargo bikes, bike trailers and the blank stares of people as you ride past with a massive load of stuff on your bike.

Thanks for this great post! A lighter lift would be just to repurpose a bike trailer meant for kids. It may not have the same weight rating, but it's probably a better initial step for those without the tools and experience required for this kit.

You must see the trailers the river bottom people have created where I live in Nor Cal. Amazing examples of engineering. Everything in their world is carried on 2 wheeled trailers, not 4 or 6. And their little dog sits right on top of everything.
