Bike Cargo Trailer

Hey guys, I’m Michael.

I’ve spent hundreds of hours testing & researching bike trailers. During this time I’ve discovered a lot of amazing insights on this topic.

Keep reading to see the best of what I’ve learned…

Bike Cargo Trailer

Bikes come with one major drawback — lack of storage space. Fortunately, you can make up for this by using a bike cargo trailer!

What is a bike cargo trailer?

Before we go any further, let us first break down the topic of bike trailers.

Bike cargo trailers are designed as a way to haul and tow extra luggage, pets, or kids along as you ride. They make it easy to carry cargo on your next cycling adventure.

These trailers would make the best option for carrying or bringing a load heavier than a pannier, frame bag, or backpack.

They are accessories that can keep the weight off your back and bike for a more comfortable ride during your cycling day venture!

As you may have guessed, you can use bike cargo trailers to carry various things. Whether it’s for camping in the woods or picking up groceries, a bike cargo trailer can be an invaluable accessory!

That is the general gist of bike trailers. Let us move on to the kinds of cargo trailers you can find in the market!

Heavy Duty Cargo Trailer

As the name implies, this bike trailer is a heavy-duty option with a larger weight capacity and more stable tracking. A heavy duty cargo bike trailer is typically a bike cart that can carry up to 125 pounds or more without causing any damage while biking and riding.

Expect heavy-duty wagons to be heavier than other trailers due to their extra thick and substantial frames.

Burley is one of the best brands offering heavy duty bike cargo trailers in the market. Particularly the Burley Flatbed Trailer.

Mountain Bike Cargo Trailer

Mountain Bike Cargo Trailer

Mountain bike cargo trailers are specifically made for going off-road. Embarking on rough terrain, and hauling gear on steep roads.

These cargo trailers typically have fat wheels that make them great for traveling off-road and off-trail.

Because mountain bike trailers are built for rough & rugged use, they are typically built with stronger than normal trailer frames.

They also usually have the best build quality and weight capacity.

Heavy Duty Bike Trailer

All bike trailers are designed to carry cargo in one form or another, but not all are fit to be called a Heavy Duty Bike Trailer.

A bicycle trailer should be made of durable materials that are manufactured to support loads much heavier than the weight of the trailer itself.

Heavy duty bike trailers should easily be able to transport heavy loads easily supported by the trailer’s frame and wheels.

Bike Cargo Trailer DIY

If you’re the handy type, you can make a DIY Bike Cargo Trailer with your own two hands!

You can build a simple and inexpensive cargo trailer using only bicycle wheels, a few pieces of lumber, and some other easy-to-acquire parts.

Of course, these are just some examples of the materials that can be used to construct your own DIY Bike Cargo Trailer. Using your own creativity and imagination you could come up with any number of possible designs and configurations using other materials like steel, aluminum, PVC, etc.

To make DIY Bike Trailer, you should sketch out a plan for the trailer using the proper measurements and dimensions you need for the load size you want to carry.

The main components of a DIY Bike Trailer are:

  • Wheels
  • Axle
  • Drawbar
  • Coupler

Here’s a cool instructional video on how to make a DIY trailer:

Create the frame according to the measurements you have in mind. You can make the frame using either wood or steel tubing.

For wood, you can attach the frame pieces using 90-degree metal screws and brackets. For steel, you will have to weld it, or use fasteners like rivets or screws & brackets.

Once the frame is finished, you’ll need to focus on the trailer platform next.

Thick, treated plywood is an excellent choice for the platform. Cut it according to the size of the frame and make cutouts on each side big enough to fit wheels. Attach the wheels to the trailer next.

You can purchase a trailer hitch and arm by visiting local bike shops or browsing online stores. You can also choose to fabricate your own type of trailer hitch, just be sure it can stand up to the weight and stresses of hauling cargo and the movement of your bike.

Attach your DIY bike cargo trailer hitch to the rear wheel hub of the bike. Screw the trailer arm on the outer piece frame of the trailer. Then, couple the hitch and arm together by inserting the end of the trailer into the hitch.

The last to do is test it out! Make sure it can carry a load without any wobbling! Keep in mind that a low center of gravity is essential with any good bike trailer. If the load sits to high on the bike trailer it will be very unlikely that it will stay stable as your ride.

The lower the load to the ground, the better, as long as you have acceptable ground clearance while riding and taking turns.

Making a DIY cargo trailer will require effort, skill, and patience, but it will be worth it when you’re getting use out of it.

Not to mention the pride of building it yourself!

Frequently Asked Questions

1. How much weight can a bike trailer hold?

How much weight can a bike trailer hold

Pulling a bike trailer along without it toppling over is only possible with the right weight capacity. Every bike trailer will come with instructions that will clearly tell you its weight limit. I strongly recommend that you do not exceed a bike trailer’s recommended weight. These have been tested at these weights for safety.

That being said, cheaper trailers can hold 40 pounds, while some higher-end heavy duty bike trailers can handle well over 200 pounds, maybe even more. If you plan to carry multiple kids or have lots of gear, then you need to pay careful attention to the weight capacity of the bike trailer, as well as the placement and balance of your cargo load.  

2. Are bike trailers heavy?

An average bike trailer weighs about 20-40 lbs. Factoring the weight of the kids, pets, or items, the total weight you are pulling while riding the bike can range from 40-100 lbs. If you plan to go on long rides with hills and steep roads, then you need to consider the weight of the trailer.

3. How many wheels do bike trailers have?

Bike trailers can have up to 4 wheels.

Single wheel cargos are the best trailers if you plan to bike on a hilly area or terrain while hauling smaller loads and gear. The single wheel helps navigate through a narrow trail and terrain.

Two-wheel bike trailers are more suitable for urban settings like sidewalks and bike lanes. You can use these to help pick up your groceries or ride to school.

Four-wheel cargo trailers are appropriate for those who need larger weight and storage capacities.

4. What are the types of cargo trailers for bikes?

Some of the most notable types of cargo bike trailers are:

There are types of bike cargo trailers that are fit to carry kids or a pet. A bike trailer for kids offers a comfortable space for a child to rest on during a family bike ride or a grocery run.

Dog trailers are obviously made for dogs and other pets. These are usually enclosed, with no seats and a few other features like an interior leash attachment.

Flatbed bicycle trailers are lightweight and can carry up to 100 pounds of weight and gear. With its open back, top, and front, a flatbed can carry almost any size and is one of the best at tracking and stability.

5. How Much is a Bike Cargo Trailer?

The price of a bike trailer varies depending on the type, features, brand, and weight capacity. You can find some pretty decent bike trailers at around the $100 price point.

Bike trailers in this price range are usually lightweight and can carry lighter weight and storage.


Most bike trailers fall around the $100-$200 price range. They are often made of sturdy materials like aluminum and steel with a higher weight capacity.

Cargo trailers in the $200-$300 price bracket have unique features and are often from reputable brands like Burley.

6 . What should you consider when buying a bike cargo Trailer?

Here are a couple of things to take note of before buying your own bike trailer:

Bike Trailer Suspension

When buying a cargo trailer, make sure to check the suspension carefully. Suspension can influence the trailer’s carrying capacity and ability to withstand shock.

Bike trailer suspension is vital if you use your bike cargo trailer on rugged terrain. Trailers with lower suspensions can help trailers handle shock and keep things from falling off.

Bike Trailer Design

When choosing a design, consider the trailer’s ease of use. If it’s foldable it will be easier to store.

Also, check the hitch since it determines the stability of a trailer when taking corners.

You will also need to decide on the style of the trailer — whether you want a flatbed, cargo, a travoy, a tow, or an enclosed trailer.

Bike Trailer Carrying and Load Capacity

Amongst your top priority should be the loading capacity. If you plan on carrying heavy items, get a trailer with a large weight and gear capacity.

If you plan to use it for a normal ride for groceries a single wheel trailer might be the best option. Two-wheeled cargo and flatbed trailers are better for heavier items.

Bicycle Trailer Cover

Decide whether you want an enclosed case or an open frame cover type.

Open trailers can carry larger size loads and often come with a strap, bag, or other types of wagon attachment that you can connect to your bike’s seat post or axle.

An enclosed cover cargo trailer usually features a removable top cover that protects your belongings and gear from external elements like rain and moisture.

7. What are the usual bike trailer accessories?

Cargo trailers have a wide assortment of compatible gear bags to keep your gear dry, clean, and organized.

Some trailers also have swappable attachment systems to make them more compatible with wheel sizes, rear axles, and brake configurations.

Another accessory you should have is additional bike mounts. Additional covers are also something you should look into.

Burley and Schwinn are notable brands you can look into if you are searching for the best quality accessories.

8. What are the top-selling bike cargo brands in the market?

Various reputable brands in the world sell trailers for bikes. Some of the notable ones are:

  • Burley Design Bike Trailer
  • Bob Trailer
  • Bakcou Bike Trailer
  • Aosom Bike Trailer
  • QuietKat Bike Trailer

Burley Flatbed, Nomad, and Travoy are very popular bike trailers right now. These bike trailers have earned positive written reviews and high-star reviews.

9. How do you mount a cargo trailer to your bike?

The two main methods for attaching a cargo bike trailer to your bike:

  • Rear wheel axle attachment
  • Seat post attachment

It depends on the bike type, whether it is a quick-release or thru-axle. Most bike trailers are designed for standard quick-release bicycles.

You won’t have any issues attaching bike trailers on a quick-release bike.

However, you might struggle in finding a suitable bike trailer if you own a thru-axle bike. If you have a Burley, Thule, or Hamax trailer, you can purchase a thru-axle adapter to fit the coupler attachment of your bicycle.

Others add the trailer to their bike’s seat post or on the eyelets on the frame’s rear triangle. You may want to search for a spare hitch kit if you plan on using the trailer on multiple bikes.

10. Are single-wheel trailers better than double-wheel trailers?

The answer depends on several factors. On single-wheel trailers, the wheel will roll behind your bike’s rear wheel. On two-wheel trailers, the wheels are mounted on either side.

Single-wheel trailers are lighter, with less rolling resistance and better aerodynamics. Single wheel trailers also usually track really well behind your bike and it can even sometimes feel like they’re not there at all. That’s how natural they can feel to haul.

Two-wheeled trailers are more stable on flat surfaces, with a larger load capacity. Though two wheel trailers can sometimes have stability issues on rugged or uneven surfaces like offroad and singletrack trails.

Conclusion

If you have extra things to bring when you bike, it’s worth investing in a bike cargo trailer. Just choose wisely by considering all these factors.
