20-inch bike: what age is suitable and other selection criteria
Cycling has seen a rise in interest in the past few years.
Now there are all the opportunities to introduce the smallest family members to this active pastime. children’s bicycles and pedalless models (balance bikes) can be purchased for children from 1 year old.
The right choice of a children’s bike is a guarantee of its long-term and safe use.
Bike selection criteria
Before making your first purchase, consider the following criteria:
- How old is the child. Convertible models for the smallest are provided with additional balance wheels, parental handle, handlebar limiter.
- Child’s height. Correct position. sitting on the saddle, leg fully extended and steady on the pedal in its lowest position.
- Saddle and handlebar position, possibility and ease of their adjustment.
- Vehicle weight. Better to climb the stairs, the little owner himself could carry and turn it.
- Floor. In addition to design differences, the girls’ vehicle is equipped with a lowered frame.
- Safety. The transport for small children has a chain cover, rubber steering wheel protection and a rear brake.
After purchasing even the safest vehicle, it is recommended to start riding only with the introduction of protective equipment, such as:
- Elbow pads;
- Knee pads;
Bicycle 20 inches at what age
12-inch wheels are designed for 90-95 cm height and 2-4 years old, 3-5 years old with 100-105 cm height, 14-inch wheels are needed.
For children with a height of 105-110 cm, age from 4 to 6 years old, 16-inch models are suitable, and with a height of 110-120 cm, age from 4 to 7 years old. 18-inch models.
These vehicles already have a front shock absorber and the ability to shift multiple speeds.
The bicycle, with 20 inches wheels, is suitable for children aged 6 to 11 and height 125-140 cm.
During the period of active development of the child’s body, age is less important for the acquisition of a two-wheeled vehicle than growth, which must be guided first of all.
Bicycle 24 inches how tall
A bicycle with a wheel diameter of 24 inches is designed for a child of 140-155 cm, which corresponds to the age of 10 to 14 years.
Bicycles for children and teenagers with 24-inch wheels in their configuration are NOT inferior to some models for adults, but are easier to control, Equipped with a soft suspension and a thin handlebar.
Here are children’s models in them light weight remains. 10-12 kg, a high position of the steering wheel, which is necessary for proper body support, a design made in bright colors.
When buying a children’s bicycle, you need to pay attention to the characteristics of the model that interests you, because With a wheel diameter of 20-24 inches, there may be different options for the height of the lower saddle position, steel and frame rigidity, steering wheel position settings, etc.
Dimensions of children’s bicycles
The manufacturer, when producing a children’s bike, knows that the baby is growing very quickly. And therefore, he makes some size adjustments and tries to make the frame in such a way that the adjustment range is as wide as possible. However, the dimensions of the frame should not be taken into account as much as the diameter of the bicycle wheels. High and maximum speed controllability depends on this parameter. You should NOT measure your baby with a caliper, you still DO NOT know how he will grow in six months or even a couple of months, so a child’s bike should be chosen with some margin.
Here is a sample size chart for children’s bicycles.
Take a minute and measure your height without shoes. It is important to know your height in order to choose the right bike, taking into account its size.
The size is the dimensions of the bicycle frames in inches, centimeters, or written in symbols. Bigger frames (L, XL, XXL) are built from thicker tubes to support the taller rider’s weight. A smaller bike has an average weight of 150-200 grams less than in the neighboring larger size. A bike with a small frame is more maneuverable and easier to hold upright than a bike with a huge frame. On models with a large frame, you can take the ideal position, Chisinau develop the maximum speed.

Children’s bicycles. Difficulties and features of choice
Choosing a bike for a child is a rather specific task. And the main thing to consider is that children grow up very quickly. Today, the size distribution of children’s bicycles is based on height and age. And the fact is that in many articles and on the forums there are rather conflicting advice on choosing. We bring to your attention a detailed and accurate table that will help you choose the right frame size for your child.
How to choose a bike for your height
The larger the diameter of the wheel, the greater the speed, but only more effort is needed to spin the wheel.
Surely every second (even every first!) Blog reader has a bicycle. an affordable vehicle that does not harm the environment. Easy to store, maintainable at home, easy to use both in the park and on the road.
In this article, we will tell you how to choose the right types of bicycles for height: children’s, mountain, hybrid and Road.
The inner side of the legs and why it really matters
Yes, the main parameter in the choice is your height. However, in order to accurately select the desired frame size, you also need to make the correct measurements on the inside of the legs. To do this yourself, you need no shoes only in your underwear, the floor with your back to the wall. The knees must NOT bend and the pelvis and heels must touch the wall. In order to take a measurement, you can use a building level or a tape measure. The easiest way is to make a mark on the wall surface and measure the height strictly perpendicular to the floor. This will be the height of the inside of your legs. If there is such a possibility, then measurements are best performed initially in inches. This will greatly simplify the choice and protect you from having to recalculate units of measurement at the time of purchase.
Once you know the inside length, calculating the required frame size becomes much easier and more accurate. But please note that you will have to make a miscalculation yourself, and for each category of bicycles the formula is partially different.
- Bicycles of the double suspension category. To calculate your internal leg length, you need to multiply by 0.225. That is, if the legs are 80 centimeters long, calculate as follows: 80 x 0.225 = 18 inches. In this case, you can choose a frame size of 17 inches for sporty riding, and 19 for touring.
- When choosing MTB bicycles and hardtails, the coefficient by which the length of the legs is multiplied is 0.226.
- For road and cyclocross bikes, the coefficient is 0.635. The result must be divided by 2.54.
- For cross bikes, the coefficient is 0.259.
Frame marking by size
There is a worldwide tradition of marking all bicycle frames with letters, numbers and their combinations. Consider the main types of frame markings in different manufacturers.
There are a total of 6 frame sizes for seat tube height:
- XS is the smallest bike size for the smallest riders;
- S. small;
- M. medium frame variant, the most common;
- L. slightly above average;
- XL. large;
- XXL. well, very large.
And this is where the confusion begins, because each size has two numerically equivalent options. This equivalent is conditional and serves to approximately determine the correspondence of your physical data with the data of a particular frame. And here is this table:
If someone is interested, then the data in this table is calculated using the formula for selecting an adult bike. According to your parameters, where “d” is the length of your legs, and “D” is the size of the frame. Now we will try to determine by the formula: D = d0.56 / 2.54. The formula uses two factors. 0.56 is the ratio of leg length to height, and 2.54 is the conversion of inches to Centimeters. Such arithmetic.
Since all people are different in size and the same ratio of legs and height cannot be found, this number is also very approximate.
But there are times when your data correspond to the overall dimensions of two frames at once. DO NOT buy two big ones at once. What to do in this case? Think.
- If I am planning an active cycling lifestyle, then I will choose a smaller bike size, because the smaller bike is easier to handle and therefore weighs less.
- If I am fat, then it will be difficult for me to climb the High frame.
- If I am thin and skinny, then I need to choose a frame a little larger to seem more weighty and not to be blown away by the wind. Quite serious.
- If I have already bought a bike, and it does not suit me with its size, although everything fits together according to the tables, then I probably forgot about the presence of adjustments for the saddle and handlebars, which in most cases have a very wide range. In addition, I always have the opportunity to change the stem or seat tube.
- If I have hands down to my knees, then I’ll take a bigger bike. In which case, you can always reduce the adjustment.
You can also find markings for both a child’s bike and a women’s bike. Pay some attention to them.
The bike is 26 inches tall. Tips Tricks
The problem with many novice cyclists is that they have the wrong approach to choosing a bike. They pay attention to anything: the color, the number of gears, the comfort of the saddle. But at the same time, the majority completely forgets about the most important criteria. the size of the frame. And while all the details play a role in the selection, the ratio of your height to the size of the frame is the main thing. The wrong choice can be one of the main causes of back and joint pain during prolonged skiing, and also causes more severe fatigue.
Additional tips for choosing a frame
An important factor in choosing a frame is also your personal riding style. If you are a fan of extreme riding in difficult terrain, then it is recommended to choose a frame that is one size smaller than your norm. This way you will feel more confident in difficult terrain and under heavy loads. And the bike in this case will be much more maneuverable, which is important. But if you prefer a calm and measured ride on a regular road, then it is quite possible to accurately navigate the table.
Choosing the right stem is just as important. There are really a lot of them, so we strongly recommend spending some time on the choice, so that later you DO NOT feel discomfort while driving.
Always consider your own physique. And it’s NOT so much about the load on the frame as about ride comfort. If you are thin or have a standard physique, then you can easily choose the large VELOBIKE size. For overweight people, it is recommended to take one size smaller. This bike is easier to ride, get on and off.
Remember that you can adjust the saddle position and stem at any time (but not on all bikes). In many mountain bike models, the stem cannot be adjusted, but the saddle can be raised and lowered quite significantly. If you see that the handlebars are NOT adjustable, do not rush to refuse such a bike. This is done in accordance with safety standards for bikes designed for EXTREME riding.
Choosing the size of the bike by height
Like clothes, a bicycle must fit our body in order to be comfortable, comfortable and safe. In order to buy a bicycle by height correctly, you don’t need to “feel” or sit on it. We will help you choose 100% correctly. A full article on how to choose a bike by riding style, height and price. Read here.
Typically, each bike model comes with a different frame size. This is done in order to make the trip as comfortable and safe as possible for a person with a specific height. The correct size of the bike is accurate, and it is not necessary to sit on it. Let’s make sure of this.
Frames of different sizes (also say “size”) differ in the lengths of almost all pipes. Long ago as “yardstick” the size of the frame was taken as the distance from the axis of the carriage to the end of the seat tube of the frame. For a long time, this value perfectly described the size of the frame, while its geometry was unchanged: a classic double triangle of equal pipes. With the advent of hydroforming technology, it became possible to make frames from bent tubes, the place of fitting the upper tube to the seatpost became more variable. And the length itself “release” seat tube over the top may vary, “overestimating” Thus, the size of the frame in inches became smaller and smaller to actually correspond to the height of the rider for which this frame is produced, so the vast majority of manufacturers switched to the letter designation of frame height. And it got easier. You know the M frame is right for your height and that’s all you need to know. However, there is still some confusion as some manufacturers still “sit” on outdated inches of the seat tube, someone measures it in centimeters, and in some manufacturers even letters, but the boundaries of a person’s height under each letter may differ from model to model. However, these differences are insignificant and are easily taken into account by our specialists. In order not to load you with theory, I will go from time to time to the algorithm for choosing a bike by height.
How do we choose a bike for you by height
- Take the time to measure your real height without shoes against the wall. There were cases when buyers called it with an error of up to 10 cm.
- First, we turn to the size networks of the manufacturer, for a specific model.
- If there is no such grid, then we select the size according to the standard (universal) grid, which is shown in the table below.
- Before finally determining the size of the bike, we consider the following factors:
- If your height falls on the size border, then for normal riding it is better to choose a smaller size, and for high-speed, sporty riding. Bigger size.
- When choosing frame size, please note that you must select a bike one size smaller than bicycles with wheel size 26 “-27.5”.
- Other things being equal, smaller bicycles are more maneuverable and weigh 150-200 g less than the next one. “sizes”.
- In larger frames (L, XL, XXL), the wall thickness of the pipes may be larger, since they are designed for a greater weight.
- If you have a large (extra) weight, then compensation for the strength of the bike is carried out by selecting a different model (increased strength), and not by a large frame size.
- Riding too big a bike is fraught with the danger of lack of control and injury to the perineum on the upper tube of the frame when jumping off the bike.
When Veliki.com.Ua specialists have determined the size of the bike frame, you can rest assured that it is safe and comfortable for you, but you will still have additional opportunities to adjust your fit yourself. I emphasize that this is not necessary, but you have such an opportunity.
- If you want a more slanted fit, you can lower the handlebars by moving the spacer rings under the stem to the top of the stem. Despite the seeming insignificance, you will clearly feel that your landing has become more horizontal and the support on your hands will increase.
- Replacing the stem has a big impact on fit and handling. The stem length can be from 40 to 120 mm. The shorter the stem, the sharper the bike reacts to the handlebars, the easier it is to lift the front wheel off the ground, and the shorter and more straight fit. All this is important if you prefer technical driving to speed.
- If speed is more important to you on straight sections, a longer stem will give you smoother control and “long fit”.
- Increasing the pitch angle is equivalent to raising / lowering the rudder and also affects the landing. Sometimes for a strong lowering of the handlebar, the stem is turned over, but not all stems allow this. Check the documentation and decals on the stem because riding an inverted stem can be dangerous.
- Also, to fine-tune the fit, you can move the saddle along the sled 1-2 cm back and forth.
Typical mistakes in choosing growth
Sometimes our customers rely on their own decisions about the proper height of the bike, but sometimes they are wrong. What can this lead to?
“Universal” frame growth. “And choose a bike size so that I am 185 cm tall and my wife 160 cm can ride it”. Such a desire to save money is quite justified, however, for a man size L or XL is suitable, and for a woman S or M. If you choose “universal” size, then both people will be uncomfortable to ride, and even dangerous for the youngest. In this case, everyone needs their own bike.
Child bike “for growth”.
Many people want to buy a bicycle for their child with a “spare”, but here, too, it is better not to violate the recommendations of our specialists. The fact is that a child, when riding a bike that is too big, can get injured by hitting the crotch on a high frame. Also possible “fidgeting” on the saddle, when the feet do not reach the pedals, threatens to fall off the bike. In addition, brake levers of different sizes are installed on children’s bicycles, depending on age. In this case, your child’s hand may be too shallow to apply the brake. It is very dangerous.
No corresponding growth. “No problem”, take less. In this case, you will have to push the seatpost very far out of the frame, above the maximum allowable level. This is absolutely impossible to do, because you can not only irreversibly damage the frame, but also cause yourself severe injury if the pin pulls out while driving. Sometimes “saves” in such cases, buying a long-lasting seatpost, but if you have a weight of more than 80 kg in curb weight, we do not recommend doing this. Better choose a bike for your height.
Standard table of correspondence between bicycle size and human height
|Height, cm||The size||Mountain, inch||Tourist / urban, inch|
- Frame sizing is not so straightforward. An error of one value is not critical and is quite correctable without interfering with the bike’s design. If the bike seems too small for you, you can tilt the seat up and move it back. You can also tilt the handlebars or swap the stem for a taller, longer stem. Conversely, if the bike seems too big for you.
- Your riding style is important.
Choose a smaller frame size if you:
- Prefer slow walks in the park (your back will be more upright and less stressed)
- Choosing a bike for the elderly;
- Ride in an aggressive style with a lot of jumps (a low frame will make it easier to jump and reduce the chances of getting to it if you fall).
In any case, be sure to coordinate your choice with a Veliki.com.Ua consultant. You will be sure of its correctness. We also recommend reading the article on choosing the right bike. It discusses all types of bicycles, how to choose the right bike for price and height, how not to be mistaken in the quality of bicycles.
Age from 18 months / balance bikes (bike races, balance bikes)
Balance bikes are designed for children aged 18 months and older and teach balance, fine motor skills and good habits. These bicycles do not have pedals and are propelled by a child pushing himself with his feet. These bicycles are the easiest to learn to balance, and by themselves they are the lightest of children’s bicycles. There are balance bikes with wheel diameters ranging from 10 to 20 inches. Wheels can be plastic with EVA tires or inflatable rubber. The former are much lighter, but have good adhesion only on hard or tamped surfaces. If you plan to ride outside the city, it is better to choose a balance bike with inflatable wheels.
Age 4.6 / wheel size 18 inches
Just as a 14-inch bike is an Alternative to a 12-inch bike, an 18-inch bike is an alternative to a 16-inch bike. A bike with 18 ” wheels is suitable for height 100 to 120 cm and ages 4 to 6.
Age 2 5 / wheel size 14in
Bicycles with a wheel diameter of 14 “not much different from bicycles with 12-inch wheels. A bike of this size is suitable for a height of 95-110 cm. Large wheels provide better stability, smooth ride and increased speed. But not all brands make bicycles with a diameter of 14 inches, so the choice of tires and spare tubes for such bicycles is much lower.
Age 9.11 / Wheel size 24 inches
Bicycles 24 “is often the last step to an adult size bike and is suitable for those between nine and eleven years old or 130-145 cm tall.
Like 20-inch bicycles, there are distinctive features in mountain, BMX and road models. Mountain bikes 24 “have more speeds and more suspension travel compared to mountain bikes 20”. Also mountain bikes with 24 wheels “more often can be equipped with disc or rim brakes with handlebar grips.
24-inch Road bikes extend their gear range to 21 and 24-speed, have slicker tires for higher speeds and lighter frames if your kid has racing ambitions.
Age 7.9 / wheel size 20 inches
20 “is the most popular kids bike size on the market. In addition, it is at this stage that children usually really begin to feel the bike and understand the feeling of freedom to ride it. This bike is suitable for a height of 115-135 cm or for those who are between the ages of seven and nine.
Already at this stage, bicycles begin to be clearly classified into disciplines such as mountain bike or MTB, road bike and extreme bike or BMX.
Children’s mountain bikes may have the same technologies as adult sports ones: rear suspension, a large number of gears, disc brakes. However, the rear suspension adds a Significant portion of the bike’s weight and reduces its durability, or the bike will cost the same as a good adult sports bike. The front suspension provides shock absorption and more control in tough terrain, so only needed in tough terrain. Therefore, for city driving, we recommend considering options without a suspension. In a city with such a flat terrain as St. Petersburg, a large number of speeds is also not necessary, because this greatly complicates the design of the bicycle and affects the durability. Road bicycles with a wheel diameter of 20 “usually have narrower wheels with flat tread. Comfort models come with full-size rigid fenders, a wide saddle and footrest. Sports road bikes sometimes even have a ram bar and a large number of speeds.
BMX kids’ bikes are a popular option as they have a large margin of safety and often have a simple yet striking design. Also, a big plus is that if a teenager likes BMX as a sport, he can ride his first BMX for a rather long time, because adult bicycles have the same wheel diameter and similar geometry.
Age 4.6 / wheel size 16 inches
This bike can be the next step after a bike with a wheel diameter of 12 or 14 inches, and immediately after a balance bike. Wheels with a diameter of 16 inches are suitable for height 100-115 cm or ages 4-6.
The frame of such a bicycle can be made of steel or aluminum. Aluminum is lighter and less prone to rust, but more expensive. Many bicycles of this size are in agreement with simplicity are equipped with only a rear coaster brake. Sometimes complete with a front handlebar, but some bikes have both brakes with handlebars. Children of this age have enough strength to use these brakes, but before buying, we recommend that you make sure that the brake lever is specifically designed for small hands.
Choosing a bike by height (choosing the size of the bike frame).
Online ordering of bicycles is becoming more and more popular. DO NOT worry about having to try on the bike in person first. This approach is very overrated! City bicycles and cruisers often do not have any height differentiation at all and are positioned for cyclists with an average height of 155-180 (women) or 165-190 (men).
There are many good ways to choose a sports bike to choose the right one, below we will take a look at the one that we use ourselves. The size of the bike is measured from the beginning of the seat to the bottom bracket, as in the image below.
Take off your shoes and stand with your feet about 15-20 cm apart (shoulder width apart). Measure the height from ground to crotch. Decide which type of bike you need: mountain bike, city bike, or road bike. Now you can take a calculator and calculate the size you want:
City bike. Leg (cm) x 0.685 = your frame size
Mountain bike. Leg (cm) x 0.66 = your frame size
Road bike. Leg (cm) x 0.70 = your frame size
For example, if your leg is 76 cm long, then the correct size for a mountain bike is 50 cm or 20 inches, a road bike is 53 cm, and a city bike is 52 cm.
For generalization and convenience, below is a table that can be used when selecting a mountain bike.
|145-158||60-73||thirteen “/ fourteen”||XS||33-36|
|155-172||63-76||fifteen “/ sixteen”||S||34-40|
|168-182||66-78||17 “/ eighteen”||M||43-47|
|178-190||68-81||19 “/ 20”||L||48-52|
|185-200||71-83||21 “/ 22”||XL||55-58|
|200-210||73-86||23 “/ 24”||XXL||59-62|
This table is most relevant when choosing a mountain bike with no rear suspension. When choosing a bike with a rear shock absorber, the geometry may differ depending on the purpose of the frame. In this case, it is best to clarify the information on the manufacturer’s website. At the same time, the size of a modern bicycle will be the same for a mountain bike with a wheel diameter of 26 “, including for fat bikes, and for mountain bikes with a wheel diameter of 27.5”, and for a bicycle with 29 wheels “.
Hybrids, road bikes, cyclocross bikes, gravel bikes, road bikes and track bikes all have different geometries, which makes the size chart different for them. On average, the sizes of different brands and directions can be combined into one table:
|178-183||M / L||57-59|
The height of the saddle is important when choosing a sports bike. It is extended from the seat tube. Even a couple of inches of saddle height difference can affect pedaling power by up to 50%.
|Stels Pilot 3 / Desna 2100||140-180|
|Stels Pilot 4 (7) / Desna 2200 (2500)||150-200|
|Forward / Altair||150-200|
|Shulz (other bikes)||150-200|
|Strida LT, 5.2||153-193|
|Strida SX, SD, C1||160-200|
|Giant / Dahon / Dewolf||160-180|
|Langtu (14-18 “)||140-180|
|Langtu (20-24 “)||150-200|
Unlike adult bicycles, in which the frame size changes depending on the cyclist’s height, children’s bicycles are measured by the size of the wheel. You can read more about the selection of a children’s bike at the end of the article, but you can average in one table:
|1-3||up to 95||Up to 12 “|
|here are 10||here is 140||26 “|
Problems when choosing a NOT suitable bike size and options for solving them There are bicycle elements that you also need to pay attention to when choosing a size: handlebar stem, handlebar and seatpost and the position of the saddle in it.
If you have already bought a bike that is too big, the fit can be slightly corrected by replacing the stem with a shorter stem or by extending the saddle in the “rails” to a position closer to the handlebars.
If the size is too small, the problem can be corrected by installing a longer stem with a wider bar or replacing the seatpost with a longer one with a backward bend.
Choosing the Right Size and Approximately Age
Choosing the right bike size for your child may seem like a simple exercise, but often parents do NOT consider other parameters other than age. As you will see from the recommendations that we made below, many of the sizes overlap by age and are more dependent on height, does not speak about the confidence and abilities of each individual child.
Many people choose a bike “for growth”, but it is important to consider that as the size of the wheels of the bike increases, so does its weight. In addition, a taller and lighter bike will also have a higher center of gravity, making it harder to balance and maneuver. As a result, if you choose a bike that is too big for your child, then riding may simply not be fun. Use the Age and Height Recommendations below as a guide and remember this is the best way to know if the bike is the right size. It’s to try on the bike live and let the child ride.
It is also important to note that unlike adult bicycles, in which the frame size changes depending on the cyclist’s height, children’s bicycles are measured by the size of the wheel.
Age 2. 4 years / Wheel size 12 inches
Bicycles with 12 “wheels are usually the first pedal bike for a child. Designed for ages 2 to 4, or 85 to 105 cm tall.Since this is often the first bike, it is best to opt for a simplified design without components that can complicate the riding experience, such as multiple gears, a lever-operated rear handbrake or front suspension.
Feeling comfortable is critical to the very first bike, so make sure the fit is correct and your child is happy with the bike’s appearance. The frame can usually be made of steel or aluminum. Aluminum is lighter, not susceptible to rust, but also significantly more expensive.
Often such a bike is equipped with lateral balance wheels. Sometimes there is a brake with a handle on the steering wheel, but children at this age usually do not have enough finger strength to brake.
How to choose a bike for a child 3-4 years old
At this age, children are still poorly equipped with balancers, therefore, preference is given to models with four wheels, where there are 2 main large wheels and 2 small safety wheels located on either side of the rear wheel. They can be easily removed when no longer needed.
It is NOT necessary to raise small wheels above the surface level, as in this case the child, placing emphasis on one of the wheels, will roll in a tilted position, which fundamentally contradicts proper driving. In addition, it is dangerous. you may lose balance and the bike may be turned over.
Bicycle handlebars should have foam protection (to cushion in case of head impact) and a rotation limiter around its axis. The saddle should be strong, soft, preferably rubberized.
Both the handlebar and the saddle Must be adjustable so the bike can last as long as possible. Bicycles of this configuration are usually equipped with a rear foot brake and one speed.
The design of the bike itself assumes the presence of a strong lowered frame, which is why the weight of the model is impressive, and the presence of additional wheels makes it also large-sized.
Since the average height of a child at the age of 3-4 years ranges from 98 to 110 cm, the diameter of the wheels will be 12 inches. The wheels already have a rubber tube. For safety reasons, the circuit must be covered with a metal guard.
How to choose a bike for a child 8-10 years old
The range of bikes for middle school children may be similar to the configuration for toddlers 5-7 years old, or it may be identical to adult models. Wheels will already be 20 inches in diameter, but sometimes, depending on the child’s height, 24 inches, there are no safety wheels.
In this model range they already pay attention to the pedals. they must be very durable, ideally. metal. An additional function also appears. a speed switch. A handbrake is required, and both front and rear can be located on the handlebars. Protective equipment remains relevant.
Classification of children’s and teenage bicycles
The first thing to understand is the classification of bicycles. There are two main classifications. by type and by wheel diameter.
By type, bicycles are:
- For freestyle;
- Baby and others.
Professionals classify children’s bicycles according to the wheel diameter corresponding to the child’s height. So, for example, when a baby grows 85-110cm, 12-inch wheels are selected. If the child is 110-125cm tall, 16 “wheels will do (with a frame size of about 9”). For children 115-135cm tall. wheels have a diameter of 20 inches.
If the child is between 125 and 150 cm tall, the wheels should be 24 inches (frame about 13 inches). There are teenage bicycles with 26-inch wheels designed for a child’s height from 135 to 160 cm. this is a type with a low frame of 14 inches.
How to choose a children’s bike: general recommendations
It is important to consider Not only the height of the child, the size of the wheels, but also such characteristics as the material of the construction of the bicycle, its weight, the braking system, the design of the chain, the availability of accessories. And it is imperative to pay attention to safety.
The weight of the bike depends on the frame material and the number of accessories. If the child carries the bike on his own, then this must be taken into account. The steel frame and parts are, of course, highly durable, but their weight leaves much to be desired.
When choosing a children’s bike, aluminum is preferred. This is especially true for bicycles for girls. If dropped, it is easier to lift with fragile handles.
It is not worth saving on the protection of the chain (it is protected with a special metal cover), although it increases the weight of the structure, but it ensures the safety of the child. it excludes items of clothing from entering the chain and thus the risk of injury.
Chain protection is also necessary for those considerations that road dust, dirt, water and sand, getting on the chain lubricant, significantly impair its performance properties, acting as an abrasive.
Any model of a bicycle must be equipped with a reliable braking mechanism. In a typical range for the younger age category, this is a foot brake that allows you to brake with a sharp pedaling in the opposite direction.
The hand brake is already used in the complete set of bicycles for schoolchildren. Ego is not recommended for preschoolers due to the lack of force necessary to compress the brake lever. Also, they are not put on the grounds that little children do not have sufficient concentration of attention and can simply get confused at the right time. For the same reasons, children’s models do not have a speed switch.
Fenders (to protect against dirt flying from under the wheels), headlights, reflectors and a bicycle helmet will NOT be superfluous in the complete set of the bike. On girls’ bike models, baskets are often attached to the fork. If desired, bicycles are equipped with rear seats. luggage racks.
How to choose a bike for a teenager
In fact, these are adult models with a reduced frame and a wheel diameter of 24 inches. If a teenager has a bicycle with such wheels rice, then the choice falls on adult models with a wheel diameter of 26 inches.
The choice of a bicycle for a teenager should be approached by taking his wishes and preferences. Many young men prefer stunt bikes, bicycles for motocross (BMX), freestyle, turf, freeride, downhill. Here you cannot do without the advice of a specialist.
If the bike is not intended for stunts, but involves riding on small off-road, city roads or in the yard, then you should pay attention to the following characteristics:.
Models for girls and boys are already significantly different. In structures for boys, the frames are reliable. steel, and for girls, they are lightweight, made of aluminum alloys and have a configuration with a lowered top bar. In addition, the saddle design for girls is different from that for boys.
In youth models, there is already a 24-mode speed switch (maybe less). Models Equipped with hand brakes and shock absorbers. The braking system can be disc and V-shaped. Disc preferred, but not on track bikes.
When choosing a bike, an important point is that you should pay attention not to some technical characteristics, but also to the assessment and opinion of the child himself. his desire to ride depends on this, thereby learning the world, finding new friends and playing sports.
How to choose a bike for a child 5-7 years old
The lineup of this age category differs little from the previous one. The main difference is the diameter of the wheels. Depending on the baby’s height (on average, it ranges from 110 to 128 cm) and the length of the legs, both 16-inch and 20-inch wheels can be used. They are more stable, their shock absorption properties are better than in 12-inch ones, which allows the child to overcome uneven roads with ease.
For kids 6-7 years old, the bike may already be equipped with a hand-type front brake. The rear foot brake is a must. it is reliable and acts as a guarantor of safety. The speed switch at this age is not yet relevant.
Safety wheels may still be necessary until the child feels more confident. Chain and handlebars Must be protected. Consideration should be given to additional protection for riders. knee pads, a bicycle helmet and elbow pads at this age will help protect your baby in the event of a fall.
You should pay attention to the material of the frame and spare parts. preference is given to aluminum structures, as schoolchildren prefer to transport their “iron horse” themselves, especially over high curbs. A must-have alarm bell for extreme situations.
Basic rules for choosing a children’s bike
When choosing a bike, it is important to remember that the “buy for growth” rule in this product category is completely inapplicable, otherwise it is fraught with numerous and frequent injuries.
Since with the same growth in children, the height of the legs can differ significantly, then it is imperative to take the future owner on a trip to buy a bicycle. It is clear that such an acquisition will no longer be a surprise, but it does not have to be a disappointment.
Based on the classification of bicycles, the size of the wheels is selected based on the height of the child. It can also be calculated using a simple formula: height in centimeters is divided by two and a half and again by 2.54 (inch in centimeters).
In this case, the optimal length from the front end of the saddle to the handlebar should correspond to a value equal to the distance from the fingertips of the child’s hand to his elbow. this is how the length of the frame is selected.
Mostly in bicycles for children and teenagers, each wheel size has its own frame size.
After choosing the wheels and the length of the frame, the bike itself follows. The child is placed on a bicycle while standing, so that the frame is between the legs, while the distance from the frame to the crotch should be 7-10 cm. This is necessary to safely jump off the bike. Then, while sitting on the saddle, check if the fully extended leg reaches the lower pedal and DO NOT touch the handlebars when pedaling.
In bicycles, the handlebar and seat are height adjustable. Therefore, if by some criteria the bike fits, but by some it is not, then you should try to adjust it. The steering wheel must be suitable for both height and slope. The steering angle must NOT exceed 90 °.
