Selection of a bike for girls
All the recommendations described are relevant not only for how to choose a bike for a man in height. they also apply to women. The only difference is that there is a so-called female frame. their design is characterized by a lowered top tube, thanks to which you can freely ride on such a bike in a skirt or dress. Otherwise, these bikes are no different from men’s bikes in their technical characteristics, they have the same geometry, handlebar stem, wheel diameter. Ladies mostly prefer elegant cruisers, which always have a low frame and graceful curves, but many other bikes, for example, mountain bikes, also have female models.
Additional tips for riding
There are some tips on how to choose the right bike size, which should also be taken into account when buying your own bike, they will facilitate the choice and make the subsequent ride more comfortable.
- If you are buying a bike for active riding and high speeds, it is better to take a larger frame;
- A frame of smaller dimensions is relevant for overweight people, as well as for the elderly, this also includes the diameter of the wheels and their choice of size;
- A stunt bike must be small. that is, at least 2 smaller than your standard size of a bicycle frame;
- If you are offered to pick up a supposedly “universal” bike that is suitable for any height and can be used by all family members in turn, it is better to take each a personal bike that is suitable specifically for its height;
- A small bicycle for riding cannot be made big by just raising the handlebars and saddle. All frame geometry should correspond to your height, in addition, an excessively raised seatpost can simply break under the weight of a large tall person, on
Choosing a size by weight. how to do it right?
What is better to take, focusing on its own weight and whether it should be taken into account at all if the size of the bicycle frame is classified only by the height of a man or a woman?
People with a lot of weight sometimes come to the conclusion that the larger the frame, the stronger it is, respectively, it is supposedly better to take a large sports bike so that it is guaranteed to withstand the load, but this conclusion is fundamentally wrong. First, riding a bike that doesn’t suit you will be completely uncomfortable. Secondly, it will not be possible to develop the desired speed on it either. For overweight people, it is better to take mountain or city bicycles, as they are characterized by improved performance and high strength, while cruisers, which do not have such a strong frame, for example, on the contrary, are fragile and prone to breakage. For people weighing more than 80 kilograms, it is better to take a bike with a short seatpost and a reinforced frame.
Bike frame size
How to choose the right bike frame? The mistake of many beginners is that they choose a bike for any parameters, but not for height. By color, brand, suspension, number of speeds. Of course, these parameters are also important, but even if you choose the perfect bike that does not fit in size, you risk not getting pleasure from the ride, but joint pain and premature fatigue.
The size chart for bicycles for height is as follows:
Of course, you do not need to memorize it completely: it is enough to find in the second column the range in which your height falls, and remember the numbers located in this line. the size of the frame in inches and in centimeters and its letter designation.
Of course, not every bicycle has such a range of sizes, but it will not be difficult to find running sizes. People with non-standard height outside the average are better off choosing a bike upwards if you are planning to buy a hardtail, and downwards if you want to use a rear shock. the choice of size is always an individual matter.
As for cruiser bicycles, there are very few models in their assortment, they are presented literally in 2-3 sizes, so they are best suited for men and women with a height of 1.70-1.90 and 1.55-1.80 m, respectively.
Children’s bikes and frame sizes for a child
Despite the fact that a child very quickly grows out of any things, including children’s bicycles, they also need to be selected based on growth. Putting a child on an adult bike is not only traumatic, but also not very logical. after all, it will be simply inconvenient for a child to ride such a vehicle. When choosing children’s bicycles, there are their own characteristics and their own tables. It is necessary to take into account not only the height of the child, but also his age.
How To Measure A Bike Frame
Bicycle frame dimensions table for children under 13 years old is as follows:
As you can see, the range of children’s bicycles is also sized in inches.
As in the case of adult bikes, it is better to take a frame for a child with a “non-standard” height only in the big direction, because sooner or later the child will grow up. Plus, children’s bikes usually have their own individual stem, wheel diameter and tube length that are different from adult standards like 26, 27.5 or 29 inches. this is another reason why an adult bike will be uncomfortable and cumbersome for a child, and it is worth choosing the appropriate pipe dimensions, as well as the saddle.
How to choose a bike for your height?
The first thing to look for when choosing a bike is the size of the bike frame by height in the table. This is true for both an adult and a child. All categories of bikes have their own set of sizes. Choosing the right size means ensuring a comfortable and safe ride, as well as good handling of the vehicle. A frame for an adult man or for a child is a paramount detail, both for road and mountain bikes, as well as for children and city bikes. Ask yourself which frame is best for me? Pay attention to the stem, wheel dimensions in inches, construction pipes, material.
By what other parameters can you choose the right bike for me, besides the size of the bike by height from the table of inches?
First, of course, by its purpose and riding. It can be an assortment of mountain, city, road, hybrid, stunt bikes, each with its own frame for riding. for both men and women. In addition, bikes need to be selected according to the presence or absence of a shock absorber. both front and rear, there are completely rigid models. rigids, there are two shock absorbers. softtails. And there are bikes with only one soft fork or only a spring under the saddle. There are a lot of options, and they all have their own scope. The handlebar stem, wheel diameter and bicycle frame size may differ markedly from them, so the choice must be approached individually.
How to choose a children’s bike for height
When buying a children’s version of a bicycle, you should focus not only on the age and method of riding, but also take into account the height of the child, on which the length of the frame and the diameter of the wheels depend. To determine the required wheel diameter, it is necessary to divide the height of a young cyclist by a factor of 2.5. In order to convert the value to inches, divide the result by 2.54.
For example, with a child’s height of 134 cm, you must:
To choose the right frame size for a child’s bike, you should focus on the length from the elbow to the child’s fingertips. This parameter indicates how much should be the distance from the front edge of the seat to the steering wheel.
With regard to the distance between the crotch and the frame, it should not be less than 10 cm. The bicycle must exactly match the age category of the child and his physical capabilities. Therefore, you should not take a technique with the future in mind.
Urban models are the most common, but at the same time, the simplest bicycles for both adults and children. Often they are not graded at all. The conditional distribution looks like this: women. 155-180 cm or men 165-190 cm in height. If there is a gradation, it becomes much easier to choose the optimal bike.
Urban two-wheelers often lack cushioning. In the event that the shock absorber is located at the rear (in the area of the seatpost), it will not allow the seat to be lowered to the lowest position. Therefore, it is recommended to choose a slightly smaller frame size:
Folding models are also referred to urban models, which are convenient to transport in a car, store in a small room. They are rarely distributed according to height, but in such models there are more options for adjusting the position of the steering wheel and seat than in traditional products.
How To Measure A Bike Frame
You can find out the size of the bike frame using a simple (universal) method or using the most comprehensive calculation method (it relies on other characteristics of the frame and the future bike owner).
Usually, buyers of such bicycles know which model and what size they need, but everything happens for the first time, and even professionals should find out the standard sizes.
Choosing a women’s bike
For ladies, the above size values are slightly different.
The girl can check if the bike suits her in the same way. if she prefers a frame with the upper tube raised high, like on a man’s bike. Take a road bike as an example. In cases where this tube is lowered, or a folding bike model with a single reinforced bottom tube is used, this step can be skipped.
Each size table below will help you determine the range of models you are interested in, but the main thing to know is that no size can be determined accurately. 18 or 24 inches is the manufacturer’s estimate of a very specific distance. for example, the length of the seat tube, or the distance from the center of the carriage to the junction of the extensions of the upper tube and the headset. there can be many measurements!
Therefore, it is very dangerous to buy a bike over the Internet or “by eye”. any bike should be tested in action, sit on it, feel the maximum distance from the seat to the pedals.
A more accurate and reasonable calculation will allow you to get the maximum comfort from the ride on the bike you choose.
It is not only the size of the frame that is important here, but also its effective length, or the ETT value.
To calculate ETT, the length of a line parallel to the road surface is taken. This line starts at the center of the head tube (front end of the frame) and ends at the point where the seat tube extends. The beginning and end of this line coincide with the center of the section of both pipes. The following ranges of values allow choosing the most comfortable bike according to the rule using ETT values.
The latter are for racing, sports bikes.
This approach is used in conjunction with the previous one. That is, together with the size, it is recommended to check the value of the effective bicycle length. Choosing a model that is too short will not allow you to keep your back straight while riding. A bike that is too long will also stretch your joints and back muscles.
For non-sporting (e.g. urban, road models), 5% is subtracted from the above ETT values.
The seat height is controlled by the pedaling lever. Too low a position puts stress on the knees, too high an excessive rubbing on the saddle. Children or their parents often lower the saddle for safety and build confidence, but this prevents them from pedaling effectively and can make cycling difficult. This habit of having a low saddle may persist even as adults.
There are several ways to find the correct saddle height. A good way to do this is to sit on the bike with both feet on the pedals: ask a friend for help, use a trainer, or lean against a wall. Set the pedals to the 6 o’clock and 12 o’clock positions. Your lower leg should be fully extended when your heel is on the lower pedal. If it is bent, the saddle must be raised. If you need to swing your hips to reach, or you just can’t reach, lower the saddle. You can also tell if the saddle is too high if you find yourself sitting on the narrow front of the saddle. although this can also be due to saddle slope.
The idea is that when you place your foot correctly on the pedal, your knee will only bend slightly at the bottom of the turn. Also make sure that you do not raise the seatpost higher than the manufacturer’s recommended height, as it can become unstable and even break while riding.
Features of frame types
What should you pay attention to when choosing a bike? Consider the recommendations for the type of frame.
- Versatile cross-country. The straight and clear frame makes this type a reference. When choosing, we use a universal rule and carefully look at the stem and the configuration of the saddle. They can be “unexpected” in size and seriously change the configuration.
- Road bike frames must fit perfectly, as every inch of leverage on a moving body directly affects power and speed. It is important to pay attention not only to the configuration and length, but also to the handlebars, which take on a very large load corresponding to the weight of the athlete.
- For downhill and mountain bike frames, it is especially important to leave safety distances both under the saddle and at the level of the handlebars. it makes no sense to select a configuration that will interfere with a sudden fall or full activation of the fork.
- Cruisers. The main thing is convenience. Pay attention to the position of the saddle and arms. It makes no sense to look at the nominal dimensions, since even within the model range of one manufacturer they may differ.
Center to Top (C-T)
This refers to the length of the seat tube from base to top. The base is the round piece at the bottom that holds the axle (known as the bottom bracket), and the top is where the seatpost goes into the seat tube.

The main thing in choosing a frame is the type of ride. How the bike can be used?
- Walking bike. Size is actually not really important, because the loads will be rare and not very serious. You can leave extra space for convenience: lower frame, higher handlebars to easily get off the bike.
- Racing and road riding are the exact opposite of walking. It is desirable for the sadok to have the handlebars as low as possible in order to use the extra force when pedaling. In this case, the dimensions of the frames must exactly correspond to the height of the cyclist; universal changes will not be enough.
- Tourist or urban cross-country is a universal style, general guidelines are more or less suitable for it.
Pedals / cranks
The pedals are connected to cranks that turn the chain to supply power to the bike. The pedals are standard, without clamps and with socks. | Stock photo © RapidEye
To maximize your cycling movement, you should consider using pedals without clamps or toe clamps. This way you can secure your feet, and every movement you make will help propel the bike forward better. Usually a cage, such as toe clamps, is considered bulkier than pedals without clamps, but they allow you to use your regular shoes and save you the hassle of buying cycling shoes. Clampless pedals come in a variety of styles for road and mountain bikes. The pedals used for mountain biking are reversible, making them easy to attach to rugged and changeable terrain.
Saddle position forward / backward
The forward / backward position of the saddle determines how balanced your body is, which also determines how comfortable and efficient you are with the bike. If you are looking at a regular bike, the saddle is located behind the bottom bracket. Set the saddle too far forward and you will not get maximum force, and if it is too far back it will injure your back and cause muscle tension.
One way to position the seat is to place it 2 to 2.5 inches behind the centerline of the carriage axis or spindle. You can check this distance by resting your elbow on the nose of the saddle and your fingertips on the handlebars. they should just touch, of course, if the frame or stem is the wrong size, or you have a long / short arm, this may not work. Another way to work around this problem is to place both pedals in a horizontal position and make sure your kneecap is right over the pedal spindle.
Top tube (TT)
This is the length of the top tube, which is the main connecting tube between the seat tube and the headset (at the front of the bike). It is measured from the centers of the intersecting tubes.
