Cargo bike trailer
It should be noted that domestic cyclists quite successfully manage to independently make various carts for transporting goods on a bicycle. Sometimes cyclists decide to take such a step in order to save money, and sometimes to satisfy their desire. to create something with their own hands. Buy a ready-made structure or make it yourself. everyone must decide for himself.
Cargo bike trailer and its design
Since the bike trailer is designed to carry heavy but small loads, its design must be as strong as possible. But at the same time, the bike trailer must be light and maneuverable. It is also important that in the event of any breakdown, the owner of this device can fix the problem on his own, therefore, the design of a bicycle trailer should be simple and understandable to an ordinary person.
The cargo bike trailer can be either one-piece or a prefabricated structure, additionally equipped with a cover made of waterproof polypropylene. These devices move relative to the axis of the bicycle, thereby ensuring reliability and safety when driving on a dirt country road, even when the trailer is fully loaded.
Cargo trailers can carry up to 50 kg of cargo, and sometimes up to 70 kg. One of the most lifting models is the Y-Frame bike trailer, in which you can transport up to 90 kg, while it itself is light and practical.
The undeniable advantage of bicycle trailers is their convenience during long trips. Ideal for cycling as you can take your essentials with you.
Types of bike trailers:
- unicycle. Mostly used for tourist travel. The one-wheeled bike trailer is more maneuverable and allows you to drive without problems on narrow paths and paths.
The three basic components of a bicycle trailer are:
- Frame, which as standard is a structure consisting of oblique mounting plumb lines and an aligned axle for the wheels. The frame of a bicycle trailer must be durable and reliable. As a rule, it is made from aluminum or steel profiles.
- A platform whose main task is to withstand the load. Most often it is made from plastic, MDF or plywood. When choosing a trailer, the material from which the platform is made should be compared with the weather and road conditions in which the device will be used. For example, some material may become soggy with excessive moisture.
- The system for attaching the trailer to the bike, which is one of the most important parts of the bike trailer. The maneuverability and functionality of the entire device depends on the quality of this component.
There is a wide variety of bike trailer models on the market today. When choosing such an assistant for yourself, you should give preference to already proven and well-known manufacturers. The cargo trailer can be a special purpose (for example, for transporting a surfboard) or universal, some models can be transformed into handcarts, etc.
DIY cargo trailer
The design of the cargo trailer is quite simple and laconic. As a rule, this is a box made of MDF or plywood, in which nothing but the sides of the selected height is mounted.
If you still decide to create a cargo trailer with your own hands, then first you need to prepare materials and create drawings. Fortunately, today on the Internet you can find a lot of drawings of bicycle trailers of different sizes and configurations, and to get a device, it is enough to follow the recommendations and carefully select the dimensions.
To connect the trailer to the bike, a metal tube is used, at the end of which there is a special design. a drawbar.
We offer you to watch the video on how to make a bike trailer with your own hands:
Tips for operating cargo bike trailers
In the process of using bicycle trailers, experts recommend adhering to the following rules:
- Do not overload the trailer. For any cargo trailer, the optimal load should not exceed 50-60kg. Overloading has a negative effect not only on the frame of the bike trailer, but also on the bike itself (tire wear accelerates, rims deform).
- When traveling with a trailer, take into account the increased dimensions of the vehicle. To feel more confident on the road, it is advisable to make several test drives before a long trip.
- When paving the route for movement, it is better to choose asphalt or dense dirt roads, since it is very difficult for a trailer to travel on soft and loose soil, as well as uphill.
How to make a trunk with your own hands for a bicycle. DIY bike rack: material and tools
So I decided to design the trunk myself. And I’ll tell you, I never regretted it, although I had to spend a lot of time creating a circuit and manufacturing. My project is to improve my old moped. But I’ll tell you about this some other time.
Bicycle rack: types
Before talking about how to assemble a trunk with your own hands, I think you need to explain a little what types of bicycle racks are, so that you make the right choice for yourself.
The classic, most versatile and therefore popular option for making a bike rack is to install a rear rack. It can carry various loads and even install a child seat (for example, to take your little sister with you on the road). It is best to install such a structure on the rear frame, but not behind the seat tube, which is also quite common and is a gross mistake. since in this case the trunk will be very loose, and this is already dangerous, especially if you are carrying a passenger.
I think, of all the options, the most acceptable is the first, classic type. The most reliable, roomy and durable, but the choice should be determined not only by our desire with you, but also by the type of bike.
By the way, a motorcycle rack has a lot in common with a bicycle rack and can be a good good cheat sheet. How to repair the trunk lock with your own hands read here.
DIY bike rack of different types
For me personally, for a long time, all bicycles seemed to be of the same type, and only a couple of years ago I happened to find out that this is not so, that along with budget options for a standard design, there are mountain bikes, speed bikes, and much more.
So, on a hardtail, that is, a mountain bike, it is good to put a console rack. Since this bike is not designed to carry heavy lifting loads, only the seatpost mounting option is observed here, so other types of luggage racks, although possible in this design, will however be somewhat problematic.
On a bicycle with disc brakes, it is advisable to put a classic rack, which is attached at four points. For better attachment, you can make a curved vertical strut, this is needed in order to bypass the brake caliper.
And, finally, if the bike is equipped with a rim brake structure, then absolutely any type of rack will do here, the only thing you should pay attention to is the size of the wheels, relative to which the center of gravity is selected, the size of the structure.
Now it’s time to get down to business. So, what do we need to make a homemade bike rack?
Bicycle rack: materials and tools
Different materials are used for trunks. steel, aluminum and titanium alloy. Aluminum is cheaper and allows you to get the job done faster, but it is less reliable, durable, titanium is a strong enough material, but too expensive and you will have to tinker with it, thus, the most acceptable option, both for homemade products and for a professional product, is steel. We need about a kilogram of steel with a density of 7.7 g / cm3. rectangular profile, corners and pipes.
Of the tools we need a grinder, a hacksaw for metal, a vice and a welding machine.
Trunk mounting technology
First of all, we choose the height of the future product. A very important point is the determination of the center of gravity, since it depends on this how the loaded bicycle will move on the road, whether it will be stable and manageable, or will fall on its side at the very first turn. As practice shows, the most rational solution is to install the trunk on the same level with the top of the frame.
Having decided on the center of gravity, we draw a diagram of the future product. If you are not strong in drawing, do not worry, I am a teapot in this business, I draw a dog with seven legs. Just in order not to spoil the product during assembly, you need to roughly imagine what size, what configuration it will be and, if possible, adhere to this scheme. Believe me, this is much easier than boiling a trunk by eye.
Now we proceed to the most interesting, crucial moment. We take a steel profile, bend it in a vice to the desired shape. Now we prepare corners and pipes and, cutting off the excess, we cook a perfectly even rectangle shape by welding.
When the product is somehow welded, we just have to install it on the place prepared for it on the bike and fix it. The trunk is welded onto horizontal beams and vertical racks and, for additional strength, is also fastened with bolts and nuts.
The final touch. we overwrite the unsightly seams formed from welding with a file and paint our product. Everything, work is ready. You can praise yourself for the manifestation of will and mind, and put this matter on stream.
But it is worth remembering that on the road, especially if you are used to driving over rough terrain at a good speed, trunk breakdowns may occur, for example, bolts may loosen if tightened poorly. To avoid unpleasant situations, always carry extra bolts, nuts, and insulating tape with you so that, in case of deformation of any part, you can fix it on the go.
I think now I have told everything I wanted on the topic raised. I wish you good luck in the interesting business of making the trunk and good roads.!
DIY bike rack. photo and diagram | With your own hands
I decided to sew the bag like a bicycle backpack, but it’s much easier.
Required: a shopping bag, two fasteners of a 50 cm sling, a small piece of synthetic waterproof fabric, Velcro, laces, threads, scissors. He took a small bag as a basis, of which there were many at home.
Cut out a piece of black fabric for the valve cap. Turned out and sewn around the edges. I put the lid on top of the back of the bag, inside. On the front edge of the lid, I sewed pieces of lines (with a margin) so that the fasteners move freely. The second part of the fasteners was sewn with a small piece of lines to the front of the bag. This allowed to increase the capacity of the product.
Also useful is a tool and bike repair kit
A loop is sewn on the back of the bag in the center for attaching two laces, which will help the product to be attached to the trunk in the future, which will prevent the bag from swaying while driving.
I attach the bag to the trunk of the bike with a rope, for threading of which loops from a fishing line are sewn at the top of the product. After each passage with the rope, reel in the barrel rod Very pleased with this useful homemade product!
Roomy mount for your bike
Once I saw a plastic container on sale. boxes for vegetables. I bought the most suitable one and got to work. The box is plastic, not rigid, the weakest point for attaching to a bicycle. bottom.
To strengthen the structure made of plywood with a thickness of 4 mm, we cut out a blank to the size of the bottom. Only fixed not inside, but outside. Box dimensions 140х300х400 mm.
From a metal strip 2×20 mm with a grinder, we cut out four blanks 2x20x180 mm. And since the standard rear rack is 140 mm wide, the slats overlap it in width.
I stepped back from the edge of the strip by 15 mm and drilled a hole in them. From them they laid 20 mm to the center of the workpiece and drilled holes d 6 mm. they just brush the edges of the barrel rods.
The corresponding holes have been drilled in the plywood. He connected the blanks-slats, a regular bicycle rack, plywood, a box and screwed it down with MB nuts. It turned out, maybe not entirely aesthetically pleasing, but convenient.
The whole family loves the bike. it is interesting and good for health. When leaving for long distances, it is advisable to equip the transport with spare parts. camera and patches, as well as the necessary repair tool. So I made a simple and roomy bag.
On cardboard, a marker is applied along the inner contour of the frame (top corner next to the seat) of the bike. With scissors we cut off all unnecessary and rounded the corners, we got a triangular pattern (see the picture on page 15) (the sizes are arbitrary and depend on the shape of the frame). The marker marked the places where the straps were attached to the frame.
Using a leatherette pattern, I cut out two side panels in a mirror image and prepared an average sewn tape with a small allowance along the length.
I sewed a zipper into one side. I cut out blanks for fastening belts from nylon tape.
He stroked the sides of the bag, threading the loop through the inside of the tape and simultaneously locking them in place. he turned the finished product over his face and hung the case on the bike frame, all that was left was to equip it. and you can start.
DIY bike bag
The life of the “Tourist” bicycle brand lasted for 30 long years. It was the best Soviet bicycle for outdoor activities from KHVZ. Kharkov Bicycle Plant.
Now it is retro-exhibited and hangs on the wall of the barn, making way for its owner to a new young modern two-wheeled cross-country class friend.
The stylish multi-speed bike was completely naked. just an aluminum frame with wheels! I had to splurge on additional equipment. front and rear fenders, rear rack, repair kit, spare camera, soft seat.
For the bike, I made a kangaroo bag in a frame and a seat belt bag under the seat. Now my new bike has an original look and is ready for daily commuting and travel.
Zipper with double seam.
It is convenient to put a supply of water and food, a plastic raincoat and a pump in the “kangaroo”. The rubber-boring purse contains three tire assemblies, a spare tube, glue with patches, bandage, iodine and a tow rope.
The spring clip rack mounts a bike rack or shopping bag easily. Wide plastic fenders protect the rider from mud in rainy weather. On my first rides, I adjusted the seat and handlebars of my bike to my body position.
Light and fast travel, efficient disc brakes, eternal frame and minor tweaks. what else do you need for a real trip?
How to make a kangaroo handbag for your bike
Blanks for bags with material. It can be artificial leather, the so-called eco-leather or dermatitis.
The bag pattern is easy to make from a piece of cardboard right in place on the frame. Remember to mark the straps or buckles.
The material for the bag is easily sewn on a regular machine.
The original of the already sewn bag. You can carry a lot of weight on both sides.
The thickness of the bag is based on the diameter of the frame tube, do not forget to discount. The total width of the liner for my bag is 50 mm.
The kangaroo bag is ready for installation. Adjacent yellow decorative stripe enlivens the black sheen of the leatherette,
I see no reason to make the bag removable, so I just sewed it to the frame.
Unusual bike rack
An interesting idea for a bike rack. The proposed design will make the bike a little heavier, but at the same time it is reliable and durable. You can carry anything in this trunk without worrying about the safety of the trunk itself, as well as the supporting frame.
DIY trailer trunk for walk-behind tractor
Factory trailers or hand-made carts near the walk-behind trailers are located behind the driver. When transporting heavy and oversized cargo, this allows you to maintain balance, does not block the view. Although not very convenient. constantly need to twirl.
For small weights, I made a compact boot for a walk-behind tractor. Its distinctive feature. location in front of the driver.
Lightweight frame, welded by me from a pipe d 30 mm. For the walls and bottom, tin was used 2 mm thick. The width and height of the trunk were determined based on the dimensions of the walk-behind tractor, and the length. taking into account the length of the control sticks. In other words, so as not to interfere with walking or work. The inner edge of the barrel was welded to the wheel axle, the far end. to the pipe under the bottom. It performs three functions at once: it serves as a support for the trunk, increases the rigidity of the structure, and fits with the L-shaped drawbar.
The configuration of the latter is not accidental. Inside the lower part of the drawbar there is an axis d 30 mm, on which the barrel can be turned relative to the walk-behind tractor This is very important when driving on uneven roads. The upper part fits into the “earring” of the walk-behind tractor and is fixed with a king pin. This connection provides high maneuverability and allows deployment in confined spaces.
To get rid of buying expensive rubber tires, “reset” the chassis in the original way. Cut strips from the belt drive from the combine to the rims of the old moped wheels. Tapping on the kyanik, alternately lower them into the “jets” of the wheel disks. The ends were fixed with bolts, nuts and washers (photo 2).
Types of bike rack designs
A bike ride can be extreme, a bike ride through historic sites, or a city trip. The trunk will be indispensable on any trip.
This design has two mounts: cantilever or rigid.
When choosing a trunk, there are a few things to consider:
- Rim or disc brake system.
- Number of holes for fixing the structure.
- Estimated load on the trunk.
- Strength and lightness of the installed device.
- Fastening reliability.
- One-piece or collapsible.
- Protection of bike bags getting into the wheel spokes.
Types of bike racks.
Classic (back) is a common type. Suitable for many bike models. Maximum loads allowed. Fastening at two points: on the stays of the rear triangle of the frame (in this case, loosening is reduced) and on the frame itself. In appearance, it is a welded structure with side posts.
Cantilever (quick-detachable). not suitable for transporting heavy loads (possible breakdown). This is due to the lack of solid fastening in one place (frame). The advantage of such a rack is easy installation.
Tranz — X Disk is a bicycle rack with disc brakes. The left pillar is made in the form of an arc.
Tranz — X Tour is ideal for travel enthusiasts. Lightweight, durable, reliable. Side arches. Adjustable stands allow installation on virtually any model (24-28).
Tranz — X Lite is a lightweight aluminum (up to 500 g). Suitable for city trips, cycling with lightweight backpacks.
Tranz-X console type. it is convenient to adapt to full-weight bicycles, if the installation of a classic trunk is excluded.
V-shaped bike rack. complex in design. Reliable welded construction, attached to the frame. Strength is provided by one upright and two diagonally (resembles a V from the side).
What should be the front rack
When choosing a trunk, you need to focus on personal preferences. Going on a trip, you should make sure that the structure is securely fastened. Such systems are fastened with bolts.
For those who are financially independent, you can experiment and achieve the goal, based on your own mistakes, comparing options.
There is an option to get advice from experienced cyclists or qualified specialists.
Can be installed on different types of bicycles
Consider the mount options:
Option I. There are attachment points to the frame and headstays. The connection is made at 4 points.
Option II. There are holes in the dropout, not in the feathers. Two kinds of solution:
- The rack is secured at three points with a clamp to a post or seat tube. This reduces the rigidity of the system;
- the top of the structure is attached at 2 points with a clamp to the upper stays. The mechanism is more rigid.
Option III. Lack of connection points. This incident can be solved like this:
- fasten to the top stays from below and to a convenient point from above with clamps. The design is unreliable. Can be used for short trips.
- to the chainstays and chainstays (a convenient place) we fasten with clamps. reliable system.
Two-suspension. it is difficult to install the trunk, which will be rigidly attached. The console type is more suitable here.
You can also use a rack with a stays on the rear suspension. This design is unreliable when traveling in mountainous areas.
Mounting on a mountain bike is the ideal solution; it is to make your own bracket. For reliability, fasten with clamps to the frame.
There are three types of bike by frame type:
- double suspension (mountain bikes, sports);
- hardtail (several mountain, tourist, hybrid);
- rigid (most tourist, road).
For the last 2 types, classic type trunks are suitable.
Permissible lifting capacity.
Manufacturers release roof racks, indicating the permissible load.
Let’s consider the main criteria:
Classical. Designed for 20-25 kg. Excessive load will break the connecting elements (bolts and threaded holes).
Front. Designed for 5-7 kg. The trunk is capable of supporting more weight, but it is worth having some driving skills. If you are planning a long trip, it is worth distributing the load on the front mechanism (30%), rear (70%).
Cantilevered. A load of 10-15 kg is provided. Even the smallest load will put pressure on the seatpost, frame tube and additionally dead weight. This nuance is worth considering.
Several materials are used to make bike racks.
Let’s analyze all the options:
Most trunks are suitable for pleasure trips.
Features of installing the front rack with your own hands
There are several recommendations from experienced cyclists:
- Under-file the disc brake caliper.
- The rack struts must not touch the brake system parts.
- Use brackets.
- Use the clamps with a rubber pad to avoid damaging the frame.
Tips for buying a bike rack
It is much more convenient if the trunk is fixed on the bike.
A few tips:
- Lightweight yet durable.
- Wide, long roof rack.
- Fits to the width of the bike bag.
- Raised front and back platform (prevents the backpack from slipping).
- Clamp for load.
- Adjustable rack height.
Selected manufacturers produce bike racks with hooks or load holders.
Overview of manufacturers and models
There are more and more people who like to use a two-wheeled vehicle. Manufacturers are worried not only about making bicycles, but also necessary accessories.
Quite a well-known brand Tranz X, inherent in JD Components corporation from Taiwan.
Offers a classic trunk with 3 straight struts. Universal luggage system, can be installed on several models of bicycles. The kit includes clamps and brackets. There is a bracket for clamping the load.
Czech manufacturer Author.

The manufacturer has taken care of those who love bicycles with disc brakes.
There are amateurs who have a great desire to make a trunk on their own. It is quite possible, having the technical basics and the necessary tools.
- Prepare quality material. Better to use steel profile.
- Determine trunk geometry.
- Set center of gravity.
- Install additional tubes to lower the center of gravity.
- Calculate the size of the luggage system.
- Consider the bike frame.
The self-made roof rack made of steel is reliable and practical during operation. Cheaper than factory models.
Which is better, front or rear rack?
Those who like to make tourist marches, trips in mountainous terrain, it is better to install a rear luggage system.
There are manufacturers who install roof racks on some models of cross-country, mountain bikes.

With your own hands. How to do it yourself. How to do something yourself, with your own hands. home master’s site. DIY bike rack. How to make a trunk bag for a bicycle. 2 options
I decided to sew a bag like a bicycle backpack, only much easier.
It took: a shopping bag-bag two fasteners of a sling 50 cm a small piece of synthetic waterproof fabric Velcro drawstring thread scissors. I took a small bag as a basis, of which there were many at home.
Cut out a piece of black cloth for the flap cover. I tucked this piece over and sewn it around the edges and sewed the lid to the top of the back of the bag, from the inside. On the front edge of the lid, I sewed pieces of lines (with a margin) for fasteners so that they move freely. The second part of the fasteners was sewn with a small piece of sling to the front of the bag. This made it possible to increase the capacity of the product.
A for tools and a bike repair kit is also useful on the go
From the back of the bag I sewed on the center of the loop for attaching two laces. With their help, the product will be tied to the trunk in the future, which will not allow the bag to swing when moving.
I tie the bag to the trunk of the bike with a rope, for threading which I sewed loops from the lines in the upper part of the product. After each threading, I wrap the rope around the trunk rod Very pleased with such a useful homemade product!
Do-it-yourself roomy bike rack
Once I saw on sale plastic containers. boxes for vegetables. I bought the most suitable one and got to work. The box is plastic, not rigid, and the weakest place for attaching to a bike is the bottom.
To strengthen the structure, I cut a blank out of 4 mm plywood to fit the bottom. I just fixed it not inside, but outside. Box dimensions 140x300x400 mm.
From a metal strip 2x 20 mm, I cut four blanks 2x20x180 mm with a grinder. And since the width of the standard rear trunk is 140 mm, the stripes overlapped it in width.
I stepped back from the edge of the strips by 15 mm and drilled in them along the hole. From them I set aside 20 mm to the center of the workpiece and again drilled holes d 6 mm. they just hit the edges of the trunk bars.
He drilled the corresponding holes in the plywood. I connected the blanks-strips, a regular bicycle rack, plywood, a box and tightened it with MB nuts from below. It turned out, maybe not entirely aesthetically pleasing, but convenient.

Marker marked the places where the belts were sewn in for fastening to the frame.
Using a leatherette template, I cut out two sidewall blanks in a mirror image and prepared an average sewn-in tape with a small allowance along the length.
I sewed a zipper into one of the sidewalls From nylon tape I cut blanks for fastening belts.
I stitched the sides of the bag, putting the loop of tape inside and at the same time fixing them in their places. turned the finished product onto his face. I hung the case on the bike frame, it remains only to complete it. and you can hit the road.
