The main attraction and national symbol of Bangladesh is the rickshaw. It is more than a means of transportation. Pedicab is a whole layer of art. A huge amount of human labor is invested in each such cart. Each rickshaw is unique in its own way and no two are alike. There are over 350,000 rickshaws in Dhaka alone. I suspected that thousands of artists were working on the design of such a fleet of vehicles and, of course, I wanted to see how it happened.

Our English-speaking rickshaw takes us through the narrow, dark streets of old Dhaka to the quarter where the workshops are concentrated. We are going a little late and almost all the workshops are already closed, but there is hope. And she makes excuses. We park near an open garage on a narrow street. Work is in full swing both inside and outside.

Every corner of the room is used for something. A man works in the corner by the light of a lamp. Wraps gold tape around metal parts.

Nearby, a thirteen-year-old boy assembles complex appliques from self-adhesive film.

Wooden blanks for seats are stored in another corner.

interior

The artist is working right in front of the garage door. There is better lighting here from a street lamp.

And right next to the fence, on the opposite side of the alley, the chassis is being painted.

We walk 30 meters and find a second working workshop

The artist is working in a corner.

The design of pedicabs uses a special technique, style and classic scenes with animals. Each rickshaw has surfaces on which such paintings are placed.

Most artists don’t invent anything, but simply copy the “classics” from old battered books and Japanese catalogs of vintage rickshaws. The painting depicts a meal of a deer, a lion and a tiger.

The production process is approximately the same as in the previous workshop. Assembling parts for a sliding roof. Then all this is stitched on a sewing machine.

Each cart has large rectangular surfaces, which are usually covered with large designs. Many artists work from home. Especially over such elements.

Each workshop employs approximately 6 people. The set of specialties is standard.

finished chassis

According to our rickshaw driver, a new cart costs about $300, and a used one can be found for 100-150.

Advantages

Having decided to make a tricycle with your own hands, check out its advantages compared to analogues on two wheels:

1. Anyone can use such transport, regardless of age, financial situation and physical fitness.
2. Making a model with your own hands does not require special knowledge or significant capital investment.
3. Tricycles, made by yourself or bought in a store, are much more stable on the road.
4. During operation, balance is not required, and this is a very significant factor for older people.
5. The model is equipped with a low frame that makes it easier for the rider to get on.
6. The high load capacity of the unit allows it to be used for commercial purposes.

Where to begin?

To create a three-wheeled adult bicycle with your own hands, you will need to purchase a two-wheeled model of domestic or foreign production. Depending on the chosen modification, the aesthetic side of the future vehicle will be determined.

When carrying out work, you should not rely only on the quality of the parts. Basic rules must also be followed, namely:

1. Calculate the height of the model so that the owner can sit on it comfortably.
2. Check the stability of the sample so that it does not fall over when the steering wheel is turned sharply.
3. A new bicycle must be equipped with a reliable braking system and a warning bell.
4. It is better to install new pedals and wheels to avoid slipping and slipping.
5. The steering wheel and wheels should rotate smoothly without making any extraneous sounds.

Peculiarities

The most significant point when creating tricycles with your own hands is the need to modify the frame. This will require strengthening the metal frame using profile ribs.

One of the simplest and most economical ways to create such a structure is to use a frame from Ural. You will need to cut down the rear fork and install a new frame made of duralumin pipes. The second element is mounted below the seat. This will allow you to install a container for transporting goods. Wheels connected by an axle are installed on both sides, and a sprocket is fitted in the center.

The dimensions of the frame when making a tricycle with your own hands may vary, depending on the creative ideas of the designer. The most reliable and fastest technologically for the production of the model in question is the use of a rear factory axle with a UK-65 type differential.

Bridge installation

The assembly procedure for this element is not particularly difficult, since it fits almost all classic frames. The work is performed in the following sequence:

1. First, all the stock rear end components are removed, including the stock chain, wheel, fender, rack, and hand brakes.
2. Then the UK type axle is installed on the original rear wheel seat. In this case, the stops are placed on the lower tube of the rear part of the frame, the axle is threaded through the eyes. All parts are tightened, the stops are attracted using clamps.
3. Next, a new chain is installed, which is longer than the usual analogue. To make it, you need to buy two standard chains and adjust the element to the required dimensions. To remove excess links, use the method of grinding off the rivet or installing a new lock.
4. All that remains is to configure the speed switch.

As you can see, tricycles by hand are not such an impossible task.

Brake system

The assembly of the equipment can be considered complete. However, you should pay attention to the brakes. The fact is that only disk elements are suitable for such a modification; it is not possible to install a rim version. This unit will require certain investments, but it will protect the cyclist and provide reliable operation. The purchased kit, in addition to the discs themselves, includes hubs, calipers, and a brake lever (placed on the steering wheel).

Tools and materials

To make a tricycle with your own hands, you will need to stock up on certain materials. These include:

• An old two-wheeled donor bicycle.
• Steel frame.
• Plywood.
• Body kit.
• A pair of wheels, preferably 20 inches in diameter.
• Square profile blank.
• Saw "grinder".
• Welder.
• Hammer.
• Set of keys and screwdrivers.
• Drill and hacksaw.

What will you have to spend money on?

When creating the modification in question yourself, you will need to take into account the costs of purchasing the necessary parts. In specialized stores you can easily find the necessary material. The main part that allows you to transform a two-wheeled bicycle into an analogue with three levels is the UK-6S bridge (or its equivalent). The average cost of a part is about 25 thousand rubles. In addition, you will have to buy an additional chain, gear selector, wheels and a set of sprockets.

As a result, the future owner will be able to independently design the model without significant financial costs, as well as choose an individual external design that will give the bike originality. If the work is carried out correctly, the equipment will delight the user not only with comfort, but also with reliability.

Finally

In order not to waste work on creating the unit in question, you will need to make drawings of a tricycle. In this case, making it yourself will become much easier.

Having studied these tips and choosing the right tools and material, you will get a reliable household assistant that does not require fuel, is stable, has good load capacity and an original design.

Step 1: Find an unwanted bike.

I used an old bicycle as a base and cut it in half along the black line. A bicycle must have a steel frame! Bicycles with an aluminum frame will not work. You can check the frame using a magnet.

Step 2: Assembling the trike frame.

Let's start assembling a homemade trike by creating the front frame. I decided to make it larger - measuring 100 cm by 100 cm. As it turned out later, the size chosen was not entirely optimal. The photo shows a trike frame welded from steel pipes and the back of an old bicycle.

Step 3: Trike wheels.

Now we have to install the front wheels directly on the frame. If you look at the Christiania tricycle, you will notice that the wheel axle is not located in the middle, but a little closer to the front of the frame. In addition, I wanted the steering wheel to be height adjustable. Therefore, only two steel pipes were welded to the rear of the frame, where the steering wheel is installed.

On Christiania tricycles, the wheel axle is moved slightly forward, but it remains behind the head tube. First I installed the axle in front of the head tube. After a few months, I had to position the axle like the original trike, which made the bike much easier to control.

It is better to use 20-inch wheels at the front. Thus, we lower the center of gravity and improve the control of the trike on ascents and descents. But this raises a problem - a regular head pipe is not suitable, since there is simply not enough space between the ground and the cradle. Therefore, you will have to abandon its use. Instead of a head tube, you can use tapered roller bearings, which are used in cars.

Placing the wheels at a slight angle improves bike control.

Step 4: Test the front frame.

The front frame for a homemade trike looks pretty good.

Step 5: Welding the components of the homemade cargo bike.

We weld the head tube to the front of the frame.

Step 6: The back of the homemade tricycle.

Next we will start assembling the rear of the cargo bike. The head tube from an old bicycle, welded to a steel pipe, will in turn be welded to the rear of the bicycle. You can see in the photo above that the angle at which the steel tube connects to the head tube is different from the angle on the original bike. This was my second mistake that I made.

At this stage, the homemade cargo trike looks good. But once I tried to ride it, I found that the bike could barely turn in any direction. After thinking a little about the reasons for this, I realized that the problem most likely arises from the angle of the head pipe.

After riding this tricycle for a while, I realized that I had chosen the worst angle of all possible options. On the Christiania bike the angle is 9.5°, which is the opposite of the standard caster angle on a bicycle.

In addition, by law, pedal-powered vehicles with a width of more than 80 cm require permits. Based on these considerations, I had to slightly reduce the size of the tricycle.

Consequently, the front frame had to be cut, reduced in size and another head tube taken from another old bike.

It turned out just great!

Step 7: Strengthen the back of the trike.

But the back doesn't look strong enough. Therefore, it is necessary to make another steel pipe with fastening.

Step 8: Trike handlebars.

The steering wheel consists of three pipes connected at an angle of 90 degrees. It is better to choose a curved steering wheel rather than a straight one. This will save space and allow you to sit more upright.

Step 9: Brakes.

To install the brakes, which I took from another old bicycle, I had to bolt a plate with holes to the frame.

Step 10: Completing the frame.

There are two other improvements you can make:

Step 11: Brake Adapter.

But there was still one more issue that needed to be resolved - controlling the two front brakes using one handle. While talking with a friend, he found an interesting solution - an adapter that redistributes the force from one handle simultaneously to two brakes.

You don’t have to make an adapter for the front wheel brakes yourself, but simply buy a “double brake lever.” It is quite cheap and allows you to control two brakes at the same time.

Step 12: Installing the cradle.

And the last thing that should be added is a cradle for transporting the child and things.

Choose the carrycot size according to your needs. The chosen size of the cradle suits me quite well, since I need to transport two children and luggage. Sometimes there can be four children in the cradle with their things. If you don't need that much space, you can make it smaller. Because even with a slight headwind, a large cradle will create noticeable aerodynamic drag. You can first make a mockup out of cardboard. And only after you are completely satisfied with it, move on to the tree.

You will also need to install reflectors and other necessary safety accessories.

Step 13: Adjustable Steering Damper.

The last thing that needs improvement on this awesome DIY cargo trike is the addition of an adjustable steering damper. Since it is quite expensive, I made it myself from a spring and a screw tie. I am completely satisfied with his work.

What does a rickshaw look like?

A pedicab is a vehicle for public or personal use that can carry 1–2 people, excluding the driver. Most of all, it resembles a tricycle, in one of which there is a stroller (seat), and passengers are transported on it. The driver controls the rickshaw by pedaling, that is, this type of transport is 100% environmentally friendly. In most cases, there is a small fabric canopy over the passenger seat, which helps to hide from the scorching sun. The use of this transport is possible only in the warm season.

What is needed to reconstruct a bicycle?

Before making a pedicab, it is important to prepare all the tools and elements that will be needed in the process:

• plywood made of several layers;
• metal tools;
• bicycle transmission;
• machine for grinding (leveling) corners;
• artificial leather;
• three bicycle wheels;
• metal pipe;
• nuts, bolts and other fastening elements;
• welding machine;
• foam rubber

Sequential instructions for creating a rickshaw

Important! To convert your bike correctly, you need to pay attention to the details and strictly follow the instructions. Use only high-quality materials, so you will get more durable and reliable transport.

Design

Before making a pedicab, decide on the design. There are two options for such transport. The most common is the one where the driver is in front of the passengers. Thanks to this design, the passenger seat is more stable, as it is located on two wheels. There is a second, opposite option, in which case the passengers are in the front. If you want to create a taxi and carry clients in your rickshaw, you should think about the second option, since clients like it more; for greater safety, it is recommended to go with the first option.

Important! Remember that if you choose the second option, the driver's seat should be located slightly higher than the passengers' cabin so that the driver can clearly see the road ahead.

Before you start making a pedicab, carefully check that you have all the parts and tools, since the absence of anything may make it impossible to create a pedicab with your own hands. It is best to have several parts in stock (bolts, nuts, foam rubber, etc.).

Drawing and diagram

To make a rickshaw with your own hands, it is important to prepare a drawing or diagram, at least generalized, in order to avoid significant mistakes during the creation of the transport.

Important! When creating a drawing, it would be useful to make a brief plan that will allow you to understand the order of your actions and make the production of bicycle transport clear and consistent.

Main stage of work

The basis for a pedicab is a bicycle frame, to which additional metal elements must be welded. To understand what should happen, pay attention to the tricycles and photos of finished pedicabs. The design is very simple and understandable. Remember that you need to use only durable metal, because the transport will carry 2-3 times more weight than a standard bicycle.

Then you need to attach the transmission (don’t forget about the gear-type sprocket on the drive wheel), the bicycle chain (just put it on), and the pedal mechanism. Lubricate the bicycle chain before attaching it to the pedicab. The next stage is the installation of the steering wheel; it fully corresponds to the bicycle one.

Important! To protect yourself and your passengers, you can install a steering brake and add an alarm system that will notify you of approaching vehicles.

Final details

The last stage of work on a bicycle taxi is the creation of a seat. It needs to be made of plywood, covered with leather, placing foam rubber under it for convenience. After this, you need to check all the fasteners, tighten the bolts and make sure the structure is reliable. Next, a canopy is put on the rickshaw, which will protect passengers from the sun and bad weather.

Among all types of personal and public transport, the most environmentally friendly is the rickshaw. It does not require fuel - just a person who will spin the pedals. It does not harm the atmosphere and rarely gets into accidents because it moves at the speed of a bicycle. A rickshaw can carry several passengers at the same time and help transport cargo.

Description and a little history

Today in Western countries, a pedicab is usually called a more correct term – “velotaxi”. It is classified as public transport. In essence, a rickshaw is a a special design on a bicycle base, the power of which is 1 human force. We are talking about a person who sits behind the wheel and turns the pedals. Thanks to his efforts, the bike taxi is moving forward.

Rickshaws appeared in Asia long before the invention of the bicycle. A man-driver was running along the road, pulling a cart with a passenger. Cycle rickshaws first appeared in Japan, and from there the idea traveled to other Asian countries.

Half a century ago, pedicabs filled the city streets of Europe and America. There they have special hopes and plans - rickshaws pulled by bicycles serve as entertainment for tourists. Thus, pedicabs are incredibly popular among guests of central New York, Washington, and London. A few years ago, bicycle taxis appeared in both Russian capitals. In Moscow, pedicabs travel along Pushkinskaya Square, and in St. Petersburg - along Dvortsovaya.

Each country that welcomed pedicabs brought something of its own to them. Therefore, the designs of Asian models differ significantly from European or Russian-made pedicabs. For example, in Western countries they love three-wheeled bicycle taxis. In them, the driver is located in front, and 2-3 passengers are behind him. Such carts come in open and closed roof types. But the inventive Vietnamese prefer to show their country to their guests. To do this, the driver is seated behind the passengers, and he “pushes” them in front of him. Two wheels in Vietnamese rickshaws are located under the passenger side, and one - under the driver's side.

Four-wheeled pedicabs are common in Mongolia and China.

The Russians joined the production of such means of transportation only about a decade ago. The first domestically produced pedicabs left the lines of the Armavir plant in the Krasnodar Territory. It was the Russians who came up with a way to reduce the load on the driver. They proposed installing solar panels to power the electric motor. The driver does not need to pedal furiously; he can enjoy the ride and monitor the direction of travel. Two years ago, the Russian idea found support from Chinese specialists, and the Celestial Empire began serial production of solar panels for rickshaw bicycles.

After the advent of an electric rickshaw, new ideas began to arise for the use of an unusual means of transportation. For example, this year they presented rickshaws for transporting ice cream and lemonade, rickshaw bars for resort towns, as well as kiosks moving around the city on bicycles for selling tickets.

Where to buy and how much does it cost?

The rickshaw is suitable for a family holiday within the city. On it, children and their parents can go for a walk in the park or city center. But the roads must be fairly smooth: rickshaws do not tolerate potholes and potholes. Some models can overcome small obstacles, but they are not ready for rough terrain and outright off-road conditions. Passenger rickshaws are cheaper and more accessible than thermal tank devices. If a bicycle taxi is equipped with an ice cream refrigerator, then its cost increases exactly by the price of the refrigerator.

A bicycle rickshaw for transporting goods can be equipped with a stroller basket both in the front and in the rear. The same approach applies to the production of passenger models - the cost of such Russian-made pedicabs starts from 31 thousand rubles. The cost of vehicles with refrigerators ranges from 51 to 99 thousand rubles. There are models stylized as antique carriages; they cost about 95 thousand rubles.

How to do it?

If you like a pedicab with a motor, but don’t like its cost, then you can try to make such a vehicle with your own hands from an ordinary bicycle. To do this you will need imagination, skilled hands and the necessary materials.

• durable multi-layer plywood;
• metal working tools;
• bicycle transmission;
• corner grinding device;
• several pieces of durable artificial leather;
• bicycle wheels - 3 pieces;
• metal pipe;
• fasteners;
• welding machine;
• a little foam.

First of all, craftsmen advise deciding on the design. If your idea draws the image of a pedicabs with the driver's seat in the back, then you should raise the saddle higher so that you can clearly see the road above the passengers. Create a drawing or select a ready-made one.

Use colored lines to mark the order of actions on paper so as not to get confused.

• We cook the frame. The design of the pedicab frame is simple and reliable; it is completely consistent with the frame of a regular children's three-wheeler, but should be several times stronger. She will have to withstand more significant loads.
• We fasten the transmission. When installing this driving part, it is important not to forget about the sprocket on the main wheel. The chain is simply put on and the pedals are attached. At this stage, it is important to remember to lubricate the chain and sprocket.
• Install the steering wheel. The process is no different from installing a steering wheel on a regular bicycle.
• We make a seat and an awning. The seat for passengers is made of multi-layer plywood. After the foam layer, a layer of artificial leather is laid and secured. The canopy can be made of fabric.

All fasteners, bolts and nuts need to be tightened at the final stage, when everything is ready.

The first cargo bikes appeared more than a hundred years ago. They were widely used to deliver mail, milk, bread and other goods. Such bikes gained particular popularity during World War II, when the fighting European countries experienced an acute shortage of fuel. However, with the end of the war and the advent of relatively inexpensive mass-produced automobile models, the bicycle lost its position, and for a long time, mainly motorized vehicles were used to transport passengers and goods. At the end of the 1980s, there was a surge of interest in an environmentally friendly and inexpensive means of transportation, and the streets of many cities in Europe and America were again flooded with two-wheeled horses. They can be found especially often in the Netherlands and Denmark, which compete with each other for the title of the most cycling country in the world. The cargo bike here is not exotic or a tribute to the fashion for environmental protection, but a full-fledged and ubiquitous participant in the road traffic.

Types of cargo bikes

The design of such bicycles can be very diverse and largely depends on the conditions in which they are used. The simplest type is a regular city bike, on which strong baskets made of metal rods or special luggage boxes are installed on the front and back, allowing you to transport fairly voluminous loads. This type is most popular in Amsterdam and Copenhagen, and making such a cargo bike with your own hands is quite simple.

Schwinn bicycle

Another common type of cargo bike is the bicycle truck (English name - Long John). It usually has a longer wheelbase and a smaller front wheel, allowing for a cargo platform to be placed between it and the steering wheel. The cyclist controls the vehicle using a conventional steering wheel, which is connected to the front wheel by a special structure. The carrying capacity of such bikes, often used by porters at train stations, can exceed 100 kilograms.

Long John Cargo Bike

Another option is the so-called long tail. Such cargo bikes have an extended wheelbase at the rear, which allows the installation of a special platform, trunk or additional seats for transporting one or more adult passengers.

The production of long bikes is established by the company Xtracycle, which offers not only ready-made vehicles of this type, but also special kits that allow you to create a cargo bike with your own hands from what you already have.

Long tail cargo bike

All of the above bicycles have only two wheels, which makes them quite inconvenient to use. After all, it is quite difficult for a rider to maintain balance on such a bike, especially if the bike is fully loaded. Therefore, they are most often used as cargo vehicles. Such devices can have either a direct or reverse deltoid configuration, and the luggage compartment is usually located between the wheels of the front or rear axle. Tricycles are stable on the road and do not fall even when stopped completely. In addition, they can easily increase the size of the trunk, thereby increasing the load capacity. Many bicycle manufacturers offer ready-made cargo trikes, some of which are even equipped with an electric motor, which expands the scope of this type of transport. There is also the opportunity to purchase a whole assembly, which is a bridge with a differential and sprockets, which allows you to convert an ordinary bicycle into a three-wheeled one.

DIY cargo bike

Anyone who knows how to work with tools and who is alien to technical creativity can easily make a homemade cargo bike. Drawings of such a vehicle are easy to find on the Internet, and you can use an inexpensive Chinese bike as a basis. You will also need round or square metal pipes (preferably steel), a grinder and a welding machine.

Two wheel truck

The easiest way to increase the carrying capacity of a bicycle is to install large luggage baskets on the front and rear, but this improvement is not optimal since the carried weight remains small. A fairly easy-to-manufacture alternative would be to create a Long John-type cargo bike, the design of which has proven itself well over more than a century of operation.

Cargo bike blank

In order to make such a bicycle, you will need a donor whose lower tube of the front triangle is cut off, as well as the steering tube. Instead, a long vertical steering wheel and a frame with a luggage platform are welded. The front wheel is welded to the trunk, which is connected to the steering wheel with special rods.

New Long John bike frame

Another option that does not require much effort is to increase the wheelbase of the bicycle to create a long bike. In this case, you will have to cut off the stays of the rear triangle of the frame and weld elongated ones instead, which will allow you to install a much larger trunk. You can also install a ready-made branded kit, securing it in the dropouts, then you don’t need to cut anything.

Homemade long bike

Cargo trikes

Two-wheeled cargo bikes are quite easy to make in a home workshop, but the same cannot be said about operating such a device, especially in heavy city traffic. In Asia and Northern Europe, tricycles are more often used for these purposes.

In order to make your own three-wheeled delta-shaped cargo bike, you will have to get rid of the rear triangle of the frame, and instead weld a frame with wheels and a trunk or passenger seats. You will get the well-known pedicab.

Homemade cargo delta trike

The torque in such a tricycle is transmitted to one or two wheels at once. In the second case, you will need an axle with a differential, which makes the structure heavier, but makes it more controllable and stable. You can also use a factory-made kit that attaches to the seatstays and seat tube, which again avoids cutting and subsequent welding of the metal.

Deltoid tricycles are great for leisurely trips in the country, but in urban conditions it will be difficult to control such a device, since it loses stability when cornering. Plus, you can't see what's going on with the cargo behind you or what the kids in the back are doing. Therefore, it is more convenient to use a European trike with a reverse deltoid design, also known as a christiania bike, which got its name from one of the districts of Copenhagen.

Various types of European tricycles

Almost any bicycle can be converted into such a tricycle. The donor's front triangle is cut off, and a pipe with a steering tube at the end is welded to the seat tube with feathers. A cargo platform with wheels is attached to the steering column, and a U-shaped pipe on it serves to control the resulting vehicle.

General diagram of a tricycle for street trading

There are a great many options for converting a regular bike into a cargo bike, it all depends only on your imagination and ingenuity. On the popular Youtube service you can even find a video showing how a twelve-year-old boy assembles his first cargo trike. If he succeeded, then you will certainly succeed too.

Applications of cargo bikes

Cargo bikes mainly serve the following purposes:

• Selling various goods, such as ice cream, hot dogs or hamburgers, in areas where vehicular traffic is restricted.
• Delivery of small-sized cargo in densely populated urban areas.
• Transportation of goods and tools across factories and factories occupying a large area.
• Luggage transportation at train stations and airports.
• Transportation of goods across warehouses.
• Mail delivery.
• Transportation of children.
• Collection of waste for further disposal.

As you can see, the scope of application of cargo bikes is quite extensive and is not limited only to the above options. And if you install an electric motor on a bike, then the scope of its use becomes almost limitless.

Cargo bikes have a number of undeniable advantages. They do not pollute the air, which is very important in enclosed spaces such as a warehouse or factory. The bikes do not require fuel, are inexpensive to operate and do not make noise. However, such vehicles are not without certain disadvantages. The bicycle is driven by human muscular power, which imposes restrictions on the travel range, as well as on the weight of the cargo transported. The need to maintain balance, the demands on the rider's physical fitness and his vulnerability in city traffic make many people abandon the use of cargo bikes. However, in some situations, a cargo bike is simply irreplaceable, and many of the problems described above can be solved by using a motor.

They can be used as exercise equipment that stimulates the work of muscles and the heart. In addition, such machines are characterized by increased stability and allow you to transport certain loads without the risk of falling. Let's consider the features of the unit and the stages of its independent production.

Advantages

Having decided to make a tricycle with your own hands, check out its advantages compared to analogues on two wheels:

1. Anyone can use such transport, regardless of age, financial situation and physical fitness.
2. Making a model with your own hands does not require special knowledge or significant capital investment.
3. Tricycles, made by yourself or bought in a store, are much more stable on the road.
4. During operation, balance is not required, and this is a very significant factor for older people.
5. The model is equipped with a low frame that makes it easier for the rider to get on.
6. The high load capacity of the unit allows it to be used for commercial purposes.

Where to begin?

To create a three-wheeled adult bicycle with your own hands, you will need to purchase a two-wheeled model of domestic or foreign production. Depending on the chosen modification, the aesthetic side of the future vehicle will be determined.

Peculiarities

The most significant point when creating tricycles with your own hands is the need to modify the frame. This will require strengthening the metal frame using profile ribs.

One of the simplest and most economical ways to create such a structure is to use a frame from Ural. You will need to cut down the rear fork and install a new frame made of duralumin pipes. The second element is mounted below the seat. This will allow you to install a container for transporting goods. Wheels connected by an axle are installed on both sides, and a sprocket is fitted in the center.

The dimensions of the frame when making a tricycle with your own hands may vary, depending on the creative ideas of the designer. The most reliable and fastest technologically for the production of the model in question is the use of a rear factory axle with a UK-65 type differential.

Bridge installation

The assembly procedure for this element is not particularly difficult, since it fits almost all classic frames. The work is performed in the following sequence:

1. First, all the stock rear end components are removed, including the stock chain, wheel, fender, rack, and hand brakes.
2. Then the UK is installed on the original rear wheel socket. In this case, the stops are placed on the lower tube of the rear part of the frame, the axle is threaded through the eyes. All parts are tightened, the stops are attracted using clamps.
3. Next, a new chain is installed, which is longer than the usual analogue. To make it, you need to buy two standard chains and adjust the element to the required dimensions. To remove excess links, use the method of grinding off the rivet or installing a new lock.
4. All that remains is to configure the speed switch.

As you can see, tricycles by hand are not such an impossible task.

Brake system

The assembly of the equipment can be considered complete. However, you should pay attention to the brakes. The fact is that only disk elements are suitable for such a modification; it is not possible to install a rim version. This unit will require certain investments, but it will protect the cyclist and provide reliable operation. The purchased kit, in addition to the discs themselves, includes hubs, calipers, and a brake lever (placed on the steering wheel).

Tools and materials

To make a tricycle with your own hands, you will need to stock up on certain materials. These include:

• An old two-wheeled donor bicycle.
• Steel frame.
• Plywood.
• Body kit.
• A pair of wheels, preferably 20 inches in diameter.
• Square profile blank.
• Saw "grinder".
• Hammer.
• Set of keys and screwdrivers.
• Drill and hacksaw.

What will you have to spend money on?

When creating the modification in question yourself, you will need to take into account the costs of purchasing the necessary parts. In specialized stores you can easily find the necessary material. The main part that allows you to transform a two-wheeled bicycle into an analogue with three levels is the UK-6S bridge (or its equivalent). The average cost of a part is about 25 thousand rubles. In addition, you will have to buy an additional chain, gear selector, wheels and a set of sprockets.

As a result, the future owner will be able to independently design the model without significant financial costs, as well as choose an individual external design that will give the bike originality. If the work is carried out correctly, the equipment will delight the user not only with comfort, but also with reliability.

Finally

In order not to waste work on creating the unit in question, you will need to make drawings of a tricycle. In this case, making it yourself will become much easier.

Having studied these tips and choosing the right tools and material, you will get a reliable household assistant that does not require fuel, is stable, has good load capacity and an original design.
