How to make a generator for a bike yourself?

You can make an electric generator yourself at home. For this, a stepper motor is taken as a basis.

The characteristics of the motor for the lighting fixture must be:

Bottle bike generator

The bottle electric generator has this name because of the external resemblance to a bottle. It is attached to the wheel and can be adjusted to increase or decrease power. When you move it, it turns off easily.

  • The price of generators of this type is inexpensive.
  • Almost no effect on the weight of the bike.
  • But from it the tires of the wheel are rubbed.
  • At high speed, work is accompanied by a characteristic noise.
  • And in the rainy season, energy is produced poorly.

Contactless bicycle generator

A non-contact generator is the most expensive design of all analogues. This is justified by the almost complete absence of flaws. The principle of operation is to accumulate energy from the rotation of the wheel through a magnetic field.

The generator is located close to the wheel, which has a built-in hub dynamo. Thus, there is no friction or resistance to movement as in other designs. The generator is attached in pairs front and back.

The whole principle is similar to the work of flashlights. The generator has a direct bridge for transmitting current from the outlet of the hub to the headlight. It turns out that the headlight works as an independent mechanism. Such a device does not have a stabilizer, so when driving low, the light should dim.

But this deficiency was compensated by the accumulation of energy during the trip. Thus, the headlight can remain lit even when the bike has come to a complete stop.

  • No friction, rubbing, contact with bike components,
  • Low weight,
  • Energy saving system for headlights during stops.
  • The disadvantages are high cost.

What is a bicycle generator and what is it for?

A bicycle is a structure that moves by using the legs to rotate the pedals. Rotational actions can be used to generate energy. A bicycle electric generator is responsible for this production.

It is needed for the functioning of a light headlight, like a car. An electric generator recycles some of the energy from pedaling to illuminate the road. It is convenient when driving in the dark, both on specially designated paths and on the roadway.

Dynamo hub

The hub dynamo is a magnet-enhanced conventional hub. Its mechanics consists in the formation of eddy currents. At the output, the energy becomes a current corresponding to the bicycle in strength, voltage and power. For comparison, in a car, energy with a capacity of 6 watts, and for a bicycle. no more than 2.

  • The hub dynamo is popular for its simplicity and small size.
  • It attaches to the hub, not the wheel, and does not create unnecessary friction. The current is transmitted directly to the headlamp.
  • The disadvantages of this type are the slow speed of the front wheel and the heaviness of the bicycle. Weight is corrected by a light magnet.

As you pedal, the current flows in waves, accelerating or decelerating. Therefore, a stabilizer is installed in the headlights with a bushing generator.

If the headlamp is different, then a rectifier will be needed to stabilize. The brightness of the illumination depends on the output power of the bushing. The more powerful the headlight and the less powerful the output, the dimmer the light.

The structure consists of components:

  • Anchor that wraps around the axle,
  • Ring magnet attached to the sleeve,
  • Double wires with terminals.

Types of bicycle generators, their features, pros and cons

Required materials and tools

To create an optimal power generator, you will need materials:

  • Plastic tape (flexible material) for handwheel.
  • Rectifier LEDs of 4 types, 1N400 company. 4 pairs.
  • Linear voltage regulator (stabilizing) by LinearRegulatorStandardRegulatorPos.
  • Single-watt resistor CF-100.
  • 1206 resistor 820 ohm.
  • Diode resistor up to 0.25 W.
  • One watt diode.
  • Postings.
  • 1 uF capacitor.
  • Capacity for the generator room (plastic box).
  • Plate for additional mounting space (optional).
  • Glue gun (adhesive sealant),
  • Welding machine,
  • Pliers,
  • Sharp knife.

Bicycle generator: what is it for and how to make it?

When pedaling, energy is generated that can be converted into current and thus run the headlights. Such a device allows you not to spend money on headlights with batteries or other independent energy unit.

Budget generators have an effect on bike components, which makes them wear out faster. Therefore, many people are interested in how to make an electric generator with their own hands.

Why isotonics are needed

Isotonic is a solution that has a similar osmotic pressure as blood plasma. Entering inside, the constituent substances do not affect the blood pressure and do not change its electrolytic concentration. The main function is to support the water-salt balance of the athlete, which is why trainers recommend using drinking during strength exercises.

Loss of electrolytes can lead not only to dehydration, but to seizures, nerve clamps, loss of coordination and a drop in performance.

The calorie content with the proper carbohydrate content is 600-800 kcal. for 1 liter of the mixture. This volume should contain at least 4-8% of carbohydrates from the total mass. then the isotonic will be effective. It will help in the following situations:

  • will replenish the reserves of energy spent on strength exercises;
  • maintains normal blood viscosity and composition: during the period of exercise, the blood becomes thicker, which puts a heavy load on the heart;
  • will restore the loss of fluid that comes out with sweat during power load;
  • will not allow dehydration.

An interesting fact is that the addition of sodium salts makes the athlete thirsty and makes him drink more isotonic than usual. Thus, the body itself asks for fluids for hydration: as soon as the electrolytes have dissolved, the athlete will wake up thirst and he will replenish the balance of fluids and salts.

When preparing yourself, it is important to observe the proportions of salt and glucose. If you overdo it with the addition of a sweet component, then the athlete will have a constant urge to urinate. If the proportions of substances are violated, then the body will not have enough moisture, but the drink itself will not quench the thirst and will not be absorbed.

Recipe

The liquid is preliminarily slightly warmed to room temperature, sugar or honey is added there and dissolved well. Then salt is added to the isotonic and citrus juice is slowly poured.

Recipe

Self-made isotonics can be stored in the refrigerator for several days according to their components. For example, a mixture that uses electrolytic components can be taken with you on trips. Natural formulations are more useful, but they do not last long.

Recipe

  • The third recipe has the function of an energy drink. it contains caffeine and will give you some vigor while exercising. You will need three tea bags, vitamin C tablets. about 20 pieces and half a liter of water.

First you need to brew strong tea and let it cool. Pour water into tea and add vitamin tablets. You can add 10 grams of glucose if desired. Pour the solution into a bottle and put in the freezer for a couple of hours.

Recipe

There are no difficulties in preparation: sugar is added to warm water, glucose, saline are poured in, and at the end the juice of two lemons survive. Instead of lemon juice, you can put it in isotonic, after cutting it into slices.

What is isotonic

Isotonic is a water mixture consisting of electrolytes in the proportions in which they are present in the human body. The specified definition of isotonic can be given from the point of view of chemistry, but if we consider it from the side of medicine, then the isotonic is able to maintain a constant blood composition, while not increasing diuresis. In simple terms, after consuming this mass, a person will want to use the toilet less than if he quenches his thirst in the usual way.

The composition is represented by the following components:

  • Sodium, potassium and magnesium salts. body electrolytes, which support muscle and nerve function. These are ionic compounds that exist in nature in the form of minerals that moisturize the body and remove urea and ammonia.
  • Polymers of glucose. add sweetness, make up 8% of the total.
  • Vitamins. vitamin complexes saturate and perform hematopoietic functions.
  • Taste-aromatic fillers. additives are used by manufacturers to improve the taste of the solution.

If you make isotonic yourself, then instead of fillers, you can put additives of natural origin, for example, sweeten with natural juice.

According to statistics, people who use isotonic during physical activity increase their endurance by 20%. This helps to make your workout quality and effective.

In industrial production, isotonics are produced in dry and finished form. The last option is immediately ready for use, and the powder must be diluted to the desired consistency.

Recipe

For 3 liters you need to take 2 g of sodium bicarbonate, 10 g of potassium chloride, 10 tbsp. sugar, 25 g of glucose, 1.5 g of magnesium sulfate. All components are mixed and used in training.

What isotonics are made of

To do this, you need the following ingredients:

  • Water. 3 liters
  • Sugar. 150 grams
  • Glucose solution. 60 grams
  • Soda. 2 grams
  • 1.5 ml Mg (25%)
  • 13.5 ml potassium chloride (4%)

In order to avoid salt deposits, Ka and Mg must be added in a strictly prescribed dosage. This recipe for a professional isotonic drink can be adjusted by adding a few drops of lemon or orange juice. If you add juice, you do not need to add soda: the taste of the drink will deteriorate due to the neutralization of fruit acids.

A simpler version of a tonic drink is prepared from water, soda, sugar and salt. You can use honey instead of sugar. For 1 liter of liquid, 50 g of sugar or honey is taken, a quarter of a teaspoon of soda and salt (preferably iodized).

Isotonics cannot be called a delicacy: due to the presence of minerals and glucose, they have a specific taste. But for a cyclist it’s even good: there will be no reason to get carried away and drink too much.

Isotonic for cyclists

Cycling at high intensity uses up human energy reserves. Combined with high temperatures leading to profuse sweating, cycling requires a constant replenishment of the body’s energy resources. In order to replenish the supply of glycogen, as well as maintain the water-salt balance at the required level, it is recommended to use special drinks, the most useful of which is considered to be isotonic for cyclists. Isotonic drugs have become part of the daily practice of athletes and every day they are becoming more and more popular among amateurs.

What is isotonic for?

Drinking water enriched with salts and minerals necessary for the body during cycling has a positive effect on the condition of the knee joints, calf muscles, liver, on the overall well-being of the cyclist, while their lack can lead to disastrous consequences. It is known that with a loss of 1-2% of fluid from our body weight, we experience acute thirst. Losing up to 8% of fluid, we can lose consciousness. A person dies when the 20 percent dehydration threshold is reached.

Cycling stress affects the condition of the knee joints. Deprived of moisture, the body is unable to provide the knee joint located in the patella with the required amount of lubricating fluid. Friction increases, an inflammatory process occurs, which can lead to edema of the cartilage, which is difficult to treat. In a neglected state, this problem leads to deforming arthrosis of the knee joint. the trouble of many inattentive cyclists.

During long workouts, it becomes difficult to pedal a bicycle due to cramps in the muscles of the legs. Convulsions are a signal of a lack of potassium and magnesium in the body. The calf muscles are under tremendous stress, and the need for electrolytes increases. This is why plain water is not enough to quench your thirst.

Intense workouts require glucose, so many riders replenish their stores by drinking a few sips of sweetened water or energy drinks. Often these drinks do not quench thirst, while leaving a sweet taste in the mouth. taking isotonic drugs is considered more preferable.

Finally, long rides consume generously of glycogen, which the body takes from the liver. After the resources of the liver are depleted, the athlete begins to feel a sharp weakness, which can develop into a loss of consciousness. Isotonics competently compensate for the lack of glycogen in the body.

How to take isotonic correctly

Isotonic is in many ways more useful than ordinary water, but it is not equal to it in its properties. So, due to the content of mineral salts, the drink is absorbed more slowly. In no case do not put off taking isotonic at the end of the race in order to stop and drink the entire container in one gulp! The main rule of rational satiety: drink often and little by little.

Given that cyclists are advised to consume up to 4 or even 5 liters of fluid on training days, it is recommended that the volume of the drink be distributed evenly throughout the training period. Small portions should be drunk at the following dosage:

  • for beginners. 0.5 liters per hour;
  • for professionals. 1 liter per hour;
  • for people with a strain on the heart. 0.25 liters 30 minutes before training and 1-2 sips while driving if thirsty.

During extreme heat, and in other cases, it is recommended to alternate the intake of isotonic with drinking water. Every half hour, you can take several sips from one or the other pre-stocked flask in turn. But even in cool weather, if you feel less thirsty, you still need to take a few sips every 30 minutes. We don’t sweat as much, but the body still loses water (not only with sweat and urine, but also with breathing).

In addition, the water-salt balance must be replenished half an hour after training. Do not take too much isotonic. It is not harmful to the body, but an excess of salts and minerals will not be beneficial.

Is it worth taking energy

Most energy drinks, unlike isotonic drinks, are oversaturated with caffeine and carbohydrates. As you know, caffeine is quickly addictive, and frequent intake of energy drinks has a bad effect on the functioning of the organs of the cardiovascular system. Plus, caffeine stimulates the nervous system. For those who go on a bike ride to relax and relieve stress, this may not be quite the right thing.

The only exceptions are fans of multi-day cycling trips or participants in cycling marathons. They need caffeine just to stay awake while driving the bike. In terms of healthy lifestyle, these people are beyond good and evil and definitely do not experience problems with the heart and blood vessels, since they decide to go for hours on end. So for them energy drinks are a completely reasonable alternative to dense, but not always compact snacks, and sometimes a vital boost of vivacity.

What drinks are best not to consume on a trip

We have already found out that nothing better than water in combination with sports (isotonic) drinks has not yet been invented. But in the list of very undesirable drinks, you can safely include such drinks as:

  • coffee
  • soda
  • beer or other alcohol

Coffee, if consumed frequently, can lead to increased blood pressure, shortness of breath, and sometimes heartburn. The drink is not recommended for people suffering from blood diseases or increased nervous irritability. It is not forbidden to drink a cup of coffee in the morning for vivacity a few hours before training, but you should not take it with you on a trip as an energy boost. It is not known how the body pumped up with caffeine will behave under conditions of increased stress.

If you get carried away, you can lose control of your movement. And, of course, you are breaking the rules of the road, as you drive a vehicle (which is a bicycle) while intoxicated.

In order not to feel the burden of continuous restrictions, you can diversify the water-isotonic menu with several glasses of cherry juice, ginger drink or skim milk, drunk half an hour after training.

So have a pleasant, useful, energetic and eventful ride for you.!

Isotonic: what is it for

Isotonic or isotonic drinks are needed to maintain fluid and electrolyte balance in the body.

During exercise, the body loses moisture and minerals with sweat, mainly sodium and potassium. The lack of these substances impairs performance and can harm health. For the body to function normally, the sodium concentration in the blood should be about 135 mmol / L. Losing water with sweat, the body gets rid of excess salts in order to maintain the desired concentration in the blood. If you drink only water during a long load, the concentration of salts will decrease and a dangerous state of hyponatremia will arise. a lack of sodium and other minerals. This condition is no less dangerous than dehydration.

Isotonic drinks contain the necessary substances in the right concentrations specifically for rapid absorption in the body. Therefore, isotonics quench thirst faster and more efficiently than ordinary water.

Isotonic drink with your own hands at home

If you wish, you can prepare an analogue of a sports drink at home. For this you need:

  • Water
  • Minerals
  • Flavor and carbohydrates (as needed)

Minerals (electrolytes) can be obtained from ordinary table salt or Rehydron. According to the instructions, 1 sachet is diluted in 1 liter of water, but for a sports drink, dilute the sachet by 2 liters. If you don’t have a rehydron, take 1/2 teaspoon of salt per liter of drink.

You can add carbohydrates and give the desired taste with compote, fruit juice, fruit drink or ordinary sugar.

How to choose an isotonic sports drink

Isotonic drinks are produced by many brands that are not even directly related to sports. When choosing, pay attention to the composition and taste, the brand is not so important. Try drinks from different brands and flavors to find your.

  • There are no recommendations for taste, choose what you like best. Change tastes so you don’t get bored. You can also change tastes, depending on the season. For winter, choose flavors that are pleasant in warm water, for summer. in cold.
  • The composition of most isotonic drinks is similar, but there are drinks that have isotonicity only on the label. The most important thing is no more than 4-8% carbohydrates, the presence of sodium and potassium. The rest of the elements are not that important. Carbohydrates are best obtained from glucose or a mixture of glucose, fructose and maltodextrin.

There are ready-made isotonics on sale, for example Powerade or Gatorade, but it is more profitable to buy dry.

Isotonic drinks in effervescent tablets

Isotonic composition

Isotonic contains different types of carbohydrates (glucose, fructose, maltodextrin) and minerals. The main ones are the ones that are lost most in sweat. sodium and potassium. Manufacturers add vitamin complexes, minerals, amino acids and various stimulants (caffeine, taurine, guarana) to some drinks.

Why does an athlete need electrolytes?

Electrolytes regulate water balance, are involved in nerve conduction and muscle contraction. Lack of electrolytes reduces performance, impairs coordination, and can lead to seizures and loss of consciousness. With a lack of sodium, blood pressure may drop, nausea, aversion to food, vomiting may appear.

How to drink isotonic

Drink isotonic 20-30 minutes before exercise, during exercise and immediately after. The optimal time of admission is during exercise. If it is not possible to take a drink with you to your workout, take it before the load and immediately after it. The approximate volume of drinks consumed in hot weather is 0.5-1 liters per hour.

Sometimes it is useful to train without drinking or additional food at all. So the body adapts to high loads and a lack of substances, it will be more economical to use its own reserves.

Exquisite design solutions

Standard modifications can seem boring and do not fit into the architecture of the city. Here the inventors of beauty and style come to the rescue. The imagination of designers can take any form, but we will list only some non-standard options:

  • Ferris wheel;
  • tubercle;
  • the fruit;
  • spiral;
  • guard bicycles.

The Ferris wheel is a suspended parking lot that every passer-by will notice. Its capacity, however, is small, up to six large. Free space may be at the top, but that’s okay: just spin the wheel, hang and secure the bike. Such parking is unlikely to be intended for everyone; most likely, it will be provided for employees of some organization. It is not yet possible to see her in our country, we will just admire her in the picture.

A bump is a road ledge with a slot for bicycle wheels. The depth allows you to put the bike on the ground fairly steadily, the rear wheel goes half inward. This sophisticated parking option is applicable only in closed areas and, not yet in our country. The tubercle does not imply fastening with a lock, and thieves do not sleep!

The fruit is a beautiful, roomy and heavy construction. The bicycles installed around the center will cause a smile and admiration. You can fix it with a wheel and a frame. The different widths of the compartments will not only help to hook any type of led, but also add naturalness to the fruit itself. For our cities, this option is incomparable, we are waiting!

The comb is an original interpretation of the storage compartment. Suitable for large bikes.

The immersion depth is sufficient to hook a large lock on the frame, and the capacity is at the level of a standard horizontal bar.

Bicycle guards are parking lots made in the form of bicycles. They are actively promoted by the Beeline operator: openwork bicycles with a bee-colored lure beckon to attach your bike to them, even just like that.

Covered stops with a hinged door can be referred to non-standard bicycle parking. These mini-garages allow you to hide your bike from adverse rainfall and prying eyes. You can either just close the bike or attach it to the inner tubes with a lock.

How to make a bike rack?

Cyclists who actively ride their two-wheeled friend to work and on business are forced to leave him on the street for a certain time. Due to the need to put the bike somewhere while its owner decides any issues, a special parking lot for bicycles was invented.

In a number of European countries, parking has long become part of everyday life, and you can meet it several times on the same street. In Russia, this industry has begun to develop rapidly over the past few years. And this is not surprising: more and more city dwellers prefer cycling due to high traffic congestion, and bikes attached to trees, lamp posts and stair railings do not paint the city landscape. over, leaving the bike anywhere is inconvenient for its owner.

The installation of parking facilities is carried out by business centers, educational institutions, workers’ organizations, supermarkets, road services, activists, etc. Note that bicycle parking is an invaluable plus and a reason to rejoice in the development of urban infrastructure.

Overview of street bike parking: varieties, pros and cons

Bicycle parking is a special design that can accommodate from a few to dozens of bikes. There are several common outdoor bike parking options:

  • compartment;
  • horizontal bar;
  • longitudinal.

The first option is much more common than the other two. The compartment parking is a one-piece structure with cross pipes. The front wheels of bicycles are inserted into the space between them, and the wheel is attached to the pipes with an anti-theft lock. The dimensions of the compartments can be the same throughout the structure, or they can vary. It depends on the manufacturer. Road and road bikes tend to fit in narrow spans, MTBs with wide tires will require wider bays.

The structure has considerable weight, it is problematic to move it, and it is generally impossible to drag it away. However, the installers insure themselves and secure the parking lot to the tarmac or walls, and rightly so.

The second type of bicycle parking is U-shaped pipes standing in a row. Outwardly, they resemble horizontal bars, hence the name. High horizontal bars will allow you to lean the bike against them with the frame, the mini-version is only suitable for fastening the wheel or laying the bike horizontally.

The longitudinal bicycle parking is the same compartment structure rotated 90 degrees. It resembles a rack in shape, in the floors of which the bike is placed in a horizontal position. It will not be possible to make many such sections, a maximum of three, since it is simply unrealistic to drag the bike up high.

The compartment parking is convenient because it does not take up much space, it can hold up to 15 bikes. The disadvantages include the inconvenience of attaching only the front wheel and the unsteadiness of the bike if it does not have a footrest.

The horizontal bar is more convenient in terms of fastening, but requires more installation work. The full-size version is rare, and its undersized counterpart is, in fact, the same compartment parking.

Longitudinal structures take up a lot of space; in order to organize a spacious parking, you will have to install about 5. 6 of these showcases. On the other hand, the great does not shine in front of thieves, but lies securely.

DIY bike parking

Self-owned bicycle parking is relevant in the country and in the countryside, where ordinary parking has not yet reached. Although, their absence may be within the city limits, so the question of how to build a bicycle parking complex with your own hands without special costs is very relevant. This plan can be implemented in several ways:

  • weld the compartment structure;
  • make from car tires;
  • dig U-shaped pipes.

Welding a metal frame requires precision so that the supporting elements do not warp. To protect the metal, you need to paint the structure with a moisture-resistant paint. Don’t skimp on the length of the compartments. let the bike fit into the parking lot with both wheels.

Give a second life to tires? Easily. We cut them in half, and then hammer the halves with a piece of wood along one edge. We fix the resulting parking lot to the wall or hard surface on the ground so as not to be dragged away. Another way to create a parking lot from tires is to dig them entirely into the ground, as flower growers do to create mini-fences. When dug in, pour on top with a layer of concrete.

And another type of do-it-yourself bike parking is U-shaped pipes inserted into the ground (analogue of horizontal bars). With the help of the drilling device, two trenches are made. The depth is selected in such a way that the pipes do not loosen. For additional fixing, they can be poured around with concrete.

To summarize: bike parking is definitely needed, and the more, the better. They haven’t appeared in your area yet? Then the wait is not long, but you can spend a little time right now and design it yourself.

DIY bike speedometer on Arduino

To calculate the speed of rotation of the wheel, a non-contact magnetic switch (reed switch) is used. When a permanent magnet passes by it, the signal goes to the Arduino, here the speed is calculated in miles or kilometers per hour, as a result, numbers appear on the display, and they show the speed. You can install such a device on any wheel, not even a bicycle one. The main thing. correctly indicate the radius of the wheel, because it is on the basis of this data that the speed is calculated.

Materials and tools for manufacturing: Arduino microcontroller;. magnetic switch (reed switch);. resistor (10 kOhm, 1/4 watt);. wire;. 9V battery;. LCD display;. breadboard for desoldering;. two switches.

You will also need plywood, screws, a certain amount of tools. Well, of course the Arduino IDE software.

Step one. Speedometer Electrical Circuit There are three switches in total. One switch controls the 9V power supply. The second switch is responsible for the operation of the LCD screen, using it you can turn it on or off. And finally, a magnetic reed switch, it closes the circuit in the event that the wheel makes one full revolution. The project uses a Parallax LCD monitor, it is connected to the board using three pins. One pin is supplied with 5V, the second is connected to ground, and the third output is digital, it is marked with the number 1. 10 kΩ resistors play the role of protection in the system so that an overload does not occur. Can’t connect ground and plus 5V to Arduino directly.

If the system is not working, 0 will be displayed.

After installation, the display can be checked. If everything is done correctly, then the message Hello World will appear on the screen. It is possible that the first time it will not work and you will have to re-upload the sketch.

Step five. Speedometer backlight Now you need to connect the backlight toggle switch. This is done as shown in the pictures. Remember to connect the 10K resistor to the green and black wires. Further, these wires are connected to one contact of the switch, and the red wire is connected to the second. The red wire is the power supply, it connects to the Arduino 5V. The green wire connects to D2 and the other side of the resistor to ground.

Bicycle trolley device

When it comes to bicycle carts, an equal sign is usually put between them and trailers, but this is not entirely correct. Both of these concepts denote a special device designed for the carriage of goods or passengers, however, there are certain differences in their design. A trailer can only have one wheel, and a cart must have at least two. We can say that every cart is a trailer, but not every trailer is a cart. One-wheeled trailers are used mainly by tourists and travelers for the transportation of luggage, and we are primarily interested in their use for more utilitarian and mundane purposes.

So, a bicycle cart usually has two to four wheels that are attached to a special frame. Such a frame can be made of metal, and in some cases, of wood. Typically, industrial designs use square or round pipes made of steel or aluminum alloys. Wood, due to its low cost and ease of processing, is widely used in the products of home craftsmen.

As a rule, bicycle wheels with spokes are used in the design of trailers, their diameter does not really matter and can be very different. Some models are equipped with solid metal wheels with solid rubber tires, similar to those found on children’s bicycles and hand luggage carts. The axle of each wheel is fixed in the frame separately in special mounting nests, similar to bicycle dropouts. Common axle for wheels is rarely used.

The cart is connected to the bike using a special rigid hitch or drawbar. The attachment points may differ depending on the design of the trailer. The most common are the seatpost, rear axle, chainstays or chainstays, and the trunk. Fixation is carried out using a hinge or coupling. Some models are equipped with a towbar. Many DIYers use chains, ropes, cables and other improvised devices, but such fasteners are unreliable and can be dangerous.

Many trailers are equipped with fenders and mudguards to protect cargo and passengers from dirt and stones flying from under the wheels, as well as shock absorbers.

Advantages and Disadvantages of Bicycle Trailers

But a bicycle trolley is a completely different matter. If you need to transport something, it is attached to an ordinary bike in a matter of minutes, and you can hit the road. After the task is completed, the cart is just as easily detached, and you are free to go wherever you want on your bike. Therefore, cargo bicycles are used mainly for commercial purposes, and in everyday life, a bicycle trailer is much more practical and expedient.

Bicycle carts have a number of other advantages. First of all, it is multifunctionality. There are models of trailers that, by simple manipulations, can be transformed from a loading platform into an ordinary handcart or even a garden wheelbarrow. Some of these attachments easily fit passenger seats, and you end up with a kind of rickshaw. Small footprint is another advantage. In addition, the bike trolley can be collapsible for easy storage and transport. Another plus is ease of operation, since the basis of the trailer, as a rule, is ordinary bicycle wheels. The maintainability of the structural elements is also very high.

At the same time, bicycle trailers are not without some disadvantages. Compared to special cargo bikes, they have a significantly lower carrying capacity and capacity. If for a bicycle truck of 150 kg is far from the limit, then most carts are designed for a maximum of 50-60 kg.

During the movement, the trailer can wiggle from side to side, when cornering it is quite skidding, and the maneuverability of the bike is significantly impaired. Certain restrictions are imposed on the type of bike that acts as a tractor. If you have a road bike, then you can immediately discard the thought of transporting goods. You will need something more powerful, with a solid frame and thick wheels. city bike, hybrid or mountain bike. In addition, when driving, the cart is behind, out of your field of vision, and you cannot see what is happening with the cargo or passengers.

Types of bike trailers

As we have already noted, trailers can have from one to four wheels. Single-wheeled trailers are not suitable for transporting bulky luggage, so we will focus on two-wheeled carts. Depending on the field of application, they can be divided into several main types:

Universal trucks are perfectly adapted for transporting anything, be it a crop at a summer cottage, building materials or small-sized furniture. The carrying capacity of a conventional trolley mostly depends on the quality of the materials from which it is made, and on average is about 50 kg. Larger versions use very strong pipes, and the platform area is increased.

Passenger trailers are designed to provide their riders with the greatest comfort and safety. Many of them undergo special crash tests. These bogies are wider than cargo bogies and have a low center of gravity to maintain stability when cornering. They are also equipped with seat belts, awning and shock absorbers, and sometimes a luggage compartment.

Children’s carts are similar to passenger carts, but may have some peculiarities. They are also equipped with an awning and soft seats. In addition, many models can be used as a lightweight stroller for a child.

Commercial bicycle carts are primarily large in size, otherwise their use would be unprofitable. Most often, they are used as mobile retail outlets, therefore they are equipped with special equipment, for example, a refrigeration unit for selling ice cream, a counter with taps and a place for beer kegs, a coffee machine, and so on. Also, parking lights and other optics necessary for movement on public roads are installed on such trailers.

Assembling a bike trolley with your own hands

As we have already found out, a bicycle trailer is a very necessary and useful thing in the household that can be used for a variety of purposes. Only one thing is bad. the cost of a high-quality trolley often exceeds the price of the bike itself, and a low-quality one is not needed for nothing, as it will fall apart overnight. The way out of this situation will be to assemble such a device with your own hands, which will not be difficult for a qualified home craftsman.

So, to make the simplest cart, we need two bicycle wheels of the same size, several round or square steel pipes, four thick metal plates, bolts and nuts, boards or plywood, and some other little things. You also need a welding machine, drill and wrenches.

Before assembling the base of the cart, you need to decide on the dimensions. The pipes should be cut so that two of them are equal in length to the width of the trailer. They will be frontal elements. The length of the other four, which will become the sidewalls, must be equal to the length of the cart minus twice the thickness of the pipes. Now all these elements need to be welded in such a way that the wheel fits freely between the outer and inner sidewalls. The result should be something similar to what is shown in the figure below, only we did not bend anything, and therefore our corners are straight everywhere. We don’t have crossbars either, but for greater strength they can also be welded.

Now we should take the metal plates and make cutouts in them of such a size that the axles of our wheels fit easily but tightly in them. These plates will act as dropouts and need to be welded to the frame.

On the resulting base, you can lay a flooring made of boards or plywood, install a box, seats or any other equipment that seems necessary on it. To fix it to the frame, you first have to drill holes in it, and bolts and nuts are used to fix it.

That’s all, our homemade cart turned out to be no worse than the purchased one, but we made it with our own hands, spending quite a bit of time, effort and money. All that remains is to think about the suitable connection with which your new trailer will be connected to the bike. One of the easiest ways is to attach the bike to the rear axle using a drawbar and a hinge, but you can use some other method, since there are quite a few of them, and it will not be difficult to find the corresponding drawings.

Bicycle carts have proven to be a very convenient and multi-purpose device that significantly expands the transport capabilities of a conventional bike. Modern industry produces a large number of a wide variety of devices of this type, and it will not be difficult to choose the one that suits your needs and financial capabilities. You can also make a bike trailer yourself, and in this case, you will not only save money, but also get great pleasure from the process itself.
