How to choose a children’s bike for height?
Do you want to purchase a transport on which the child will ride with benefit and pleasure? Let’s discuss how to choose a children’s bike so that it does not gather dust unnecessary on the balcony, but helps the young owner to enthusiastically learn about the world around him. What to consider when buying so that later it does not bring a big disappointment?
Classification and features of children’s cycling
To ride a bike, children must have some skill. speed of reaction, ability to keep balance, understanding “fast-slow”, “right-left”. The classification is based on the average statistical information about the abilities that are inherent in children of different ages. In accordance with it, several groups of children’s bicycles are distinguished:
Mostly these are tricycles as the most stable and therefore safe models for babies. Some bicycles have a special handle with which an adult can control transport, a rain canopy, a spacious trunk for toys. Braking system. back. At this age, it is better to choose a bike of a lightweight design with an aluminum frame for a baby. Plastic options are short-lived, while steel options are still too heavy.
This is the first transport for children to learn to ride independently. The bike is equipped with two main and two safety wheels, a soft cover on the handlebars to protect the head from accidental impacts. When the baby learns to maintain balance, the side wheels are removed. Along with the rear foot brake, bikes are sometimes equipped with a front hand brake.
Best bikes for ages 3-6
These are full-fledged two-wheeled bicycles. smaller copies of real cruisers, mountain, sports and stunt bikes. They have a reinforced, predominantly steel frame and rigid fenders. Some children’s models are complemented by “adult” details:
- shock absorbers,
- multiple speeds,
- rear suspension,
- disc brakes.
Best bikes for ages 9 to 14
If the “new thing” on wheels seems too complicated and incomprehensible to children, or, conversely, simple and boring, it will quickly go to that very balcony.To choose a bike that will be of interest to your child, take into account the individual level of his physical development and the skills he already has.
How to choose a children’s bike by size?
Road Bike. What Size Bike Should I Buy?
Reliable bike. the one that we managed to choose the right size. Do not take the model “for growth”. It is inconvenient to ride a child’s transport, which is incorrectly selected for height, and it is more difficult to control it. Sitting too high is fraught with frequent falls and painful injuries.
There is a special table for determining the right bike. But it is better to let the child “try on” the model for his height before buying. Pay attention to the important size. there should be at least 10 cm between the frame and the crotch area.Then the small owner of the bicycle can easily jump off the seat, if necessary while moving.
Choose the height of the model so that it allows your feet to calmly reach the pedals and not slouch when leaning towards the handlebars. In this position, there will be no unnecessary stress on the child’s spine. It will be a means of transportation, convenient even for long walks.
3 bicycles have the function of adjusting the height of the seat and handlebars to suit the child’s height. So a growing child will not have to buy a new bike every year. You immediately choose a model that will last for several seasons.
Best bikes for ages 6-9
This group of children’s bicycles is second only to adults with a smaller frame and wheel diameter. Choose a model taking into account the driving style of your child and his hobbies. The young speed enthusiast will love the kids’ road bike with a lot of speeds, a lightweight frame and smooth tires. The mountain is suitable for school and family hikes. If a teenager gravitates towards the field of cycling, let it be his first BMX for children.
Table “How to choose a children’s bike by height”
Age is also indicated in the table. Think of it as an approximate parameter only. Your child’s height may not match the average age ranges shown in the table. Some children grow faster, others. slower than the rest. Therefore, choosing a bike with a smaller or larger wheel size is normal.
Subjective factors in choosing a bike for a child
Mandatory attributes that a child’s bike is equipped with and that ensure safety while riding. reflective elements and a protective cover on the chain, which will not allow the pant leg to get stuck while driving. But there are nuances that affect how to choose a vehicle in each specific case:
Moscow and the region differ in the quality of the road surface in the places for walking. A bike with narrow wheels and no suspensions will give more acceleration and a comfortable ride on smooth city asphalt. For off-road travel, it is better to choose a model with wide tires and deep tread. Bicycles for babies 1 are equipped with plastic and rubber wheels. For uneven tracks that the area abounds in, the latter option is preferable.
The first impression in children is formed visually. Only then, in the process of driving, they will be able to evaluate the convenient size of the structure, compliance with growth, speed, smooth running and other characteristics. Therefore, choose a bike that looks like a young owner. Manufacturers offer children’s models in boyish, girly and versatile versions. Often the basis of the theme for the design of the frame is popular cartoon heroes and movie characters.
The second most important component of any road bike is the wheels. According to their design features, they are divided into two types. clincher and pipe.
Clincher wheels involve the use of a tire and tube. In this version, the rims have special bumpers that ensure the grip of the tire.
The tube wheels have a completely different design. Their rims do not have rims, and the tube is installed using a special glue by ordinary gluing to the rim. The tube itself has a circular cross-section and combines both a tire and a camera. These wheels provide the best rolling and handling and are also able to withstand the maximum tire pressure. But, due to the impossibility of repair in the event of a puncture, as well as the high price, they are used mainly in professional cycling.
On different road bikes, you can find rims with different profiles, heights, and also made from different materials. It all depends on the personal preferences of the buyer, as well as his financial capabilities.
Among all the variety of bicycles on the market, road models rightfully occupy a leading position. They are not designed for off-road driving. Their main task is to provide the cyclist with the maximum speed of movement on the highway, road or in the city, which cannot be achieved on any other type of bike. This is facilitated by both the light weight of the transport itself and the many design features that must be taken into account when choosing a specific road bike model.
Before choosing a highway, you need to clearly understand what advantages and disadvantages this type of bike has. Its main advantages are speed, light weight, simplicity of construction and maintenance. Also, road models are ideal for sports, fitness and general riding. Among the shortcomings, one can single out the sensitivity to the road surface, the absence of both rear and front suspension, the impossibility of installing the trunk. Generally speaking, this transport is able to give the owner maximum drive and ease of driving, significantly improve health, and also give the opportunity to see a lot of interesting and remote places.
Some novice cyclists make the mistake of trying to assemble a bike from separate components. Not only is this procedure only for experienced cyclists, but it also takes a lot of time and effort. In addition, the desire to save money can result in an even greater waste of money and lead to a dead end when choosing the wrong components.
- Frame material, type and size;
The main part of any bike is the frame. Many characteristics of the device depend on its quality (rolling, handling, comfort, etc.). The frame is not only a connecting link for all other structural elements, but also designed to withstand maximum loads while driving. There are several basic materials used in the production of road bike frames. aluminum, carbon, steel. They all have a different cost. It is because of this that the price of two identical bicycles assembled on different frames can be very different.
One of the oldest and cheapest materials for bicycle frames is steel. Such frames provide maximum ride comfort, as they tend to spring. But this advantage also translates into a significant disadvantage. The flexible, walking construction does not at all contribute to the main principle of the road bike. maximum speed, controllability and coasting. Another disadvantage of such frames is their heavy weight, which is why most manufacturers refused to use them in their bike models.
A more modern material is aluminum. Due to its properties, as well as its low price, it is most often used in the manufacture of bicycle frames. Aluminum is non-corrosive, lightweight and highly rigid. The only drawback can be considered a shorter service life compared to steel frames, which are practically forever.
Carbon is the most advanced material for bicycle frames. Many people think that carbon frames are the lightest. This is not entirely true. Often times, aluminum frames can weigh less than carbon frames. The main advantage of composite material is that it can be fabricated with varying levels of rigidity in specific locations. In this case, manufacturers are able to provide the best performance for their product. In addition, the carbon frame significantly outperforms the aluminum frame in terms of strength and rigidity, which is very important in road cycling. Since the technology for manufacturing carbon frames is very complex and painstaking, their price is quite high.
The size of the frame plays a decisive role in the purchase. An improperly selected size can not only negate any desire to ride, but also harm your health. It should be understood that the geometry and size of the frames may differ slightly for different bike manufacturers. That is why, you should not focus only on the frame size indicated in the technical specifications. To do this, it is best to use the help of a qualified specialist, or independently study the geometry, design features and frame size of a particular bicycle manufacturer.
Most road bikes come with the frame. It can be made of aluminum or carbon. The fork is selected individually for a specific bike model. All plugs have approximately the same characteristics. That is why, in this matter, it is best to rely on the opinion of the engineers of the manufacturer.
How to choose a road bike
Road bikes are analogous to Formula 1. Speed excellence is beyond competition. The full article on how to choose a bike by riding style, height and price. read here.
A large group of components belongs to road bike attachments. The main ones are connecting rods, brakes, derailleurs, cassette, chain and others.
Cranks come in several sizes to accommodate different leg lengths. Unlike mountain bikes, which can have between one and three chainrings, road bikes only use a two chainring combination. The combination of sprocket and sprocket teeth may vary depending on the type of bike and the intended use. The most popular ratios are 53-39, 52-42, 55-42. There may be other options.
The rear cassette is designed to change the gear ratio and can have a different number of stars (from 9 to 11). The range of cassette stars can vary within certain limits. As a rule, the smallest sprocket has 11 teeth, and the largest is from 21 to 32. If necessary, the cassette can be easily replaced with a more suitable one. It is only necessary to take into account that for cassettes with a wide range of stars, it is necessary to use a special rear derailleur with a medium or long back foot.
Typically, in modern road bikes, brake levers are combined with derailleurs. This design will allow you to drive as comfortably as possible, as well as instantly respond to changing road conditions.
The handlebars and saddle on road bikes are specially shaped to provide a comfortable and aerodynamic fit. Road bike pedals generally use contact pedals. Their design provides the most rigid leg connection possible. It allows you to transfer maximum force from your foot to the crankset with minimal losses. Different manufacturers offer different levels of attachments. For beginners, we recommend buying a mid-range road car with an aluminum frame and an inexpensive carbon fork. This will not only save you a lot of money, but also experience the full benefits of using a road bike. With the accumulation of certain experience, components can be replaced with more expensive ones or purchase a professional road bike.
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.
Rostovka. changing parameters of the bicycle frame in length and height. The larger the size, the longer and higher the frame.
Why is it important? With the right bike frame, you will move faster with less energy, and with an incorrectly defined size, you may experience discomfort in your back, knees, as well as problems with bike control in general, which will affect your safety.
Usually the sizes start from 13 “and can be up to 24”. The size step can be from 0.5 “to 2”. There are three types of designations for bicycle sizes:
- legend (XS, S, M, L, XL);
- centimeters (cm).
Why these tables can be trusted?
We have collected all recommendations in Russian and foreign the internet, data from manufacturers, mixed it with real experience of our team and friends and as a result. weighted recommendations were made for all classes of bicycles for all people. Of course all the data has already been verified on many sales.
Mountain, two-suspension, hybrid, city, urban bicycles, as well as fetbikes.
The largest class of bicycles, common features of the frames. therefore one table.
|Height, cm||Frame size, inches||Frame size, cm||Size|
Selection of the size of the bike frame by height. Table. How to choose?
Road, cyclocross and track bikes.
One of the most important parameters here is the length of the upper pipe. On the road. the main indicator is ETT (effective length of the upper pipe). ETT is the length of an imaginary cutter line that is parallel to the ground and extends from the top of the head tube to the intersection with the seat post. In most cases, you should use it.
|Height, cm||Frame size, cm||Size|
|178-183||56-58||M / L|
We strongly recommend that you follow this dimensional grid, as in the case of an incorrect size, you can permanently discourage your child from riding an “uncomfortable” bike.
Adjustments / settings for ergonomics and fit.
- Saddle height. Your leg should bend slightly in the lower pedal position;
- Saddle nose slope. The main thing is that you do not feel discomfort while driving;
- Shifting the saddle along the seatpost frame forward or backward (if you feel that the center of gravity of the body is shifted to one side);
- The position of the brake levers and gearshift. it is better to put them in a position where they will be an extension of your hand and landing;
- Replacing the stem with a longer or shorter, as well as lower or higher (if the landing is too low or elongated);
- Replacing the Seatpost with a Rear Offset Model.
Bicycle size selection
Now you can define the required frame size:
The actual size of the frame should be chosen by subtracting a certain amount from the theoretical size. Typically, this is about 5 cm (2 inches). When choosing a size, you should proceed from the fact that a bicycle for sports use will be slightly smaller than a bicycle for calm riding. In any case, when choosing a bike, you should sit on it and determine whether it is convenient for you or not.
- For a road bike: multiply the crotch height by a factor of 0.665. The resulting value will show the theoretical size of the frame in centimeters. For a triathlon bike, subtract 3 cm from the calculated value.
- For mountain bikes: multiply the crotch height by a factor of 0.226. The value you get will show the theoretical frame size in inches. To get the size in centimeters, the resulting value must be multiplied by 2.54.
- For touring and trekking bikes: multiply the crotch height by a factor of 0.66. The value you get will be the theoretical size of the frame in centimeters. If you multiply the crotch height by 0.259, you get the frame size in inches.
