How to choose the size of the frame of the bike in height?

A frame for a bicycle is one of its most important components. It is on her that the comfort of landing and control of the bike depend, which is much easier with a correctly selected frame. It is worth paying attention to the fact that different frames are designed for men and women for greater convenience and ease of use. However, the most universal criterion for choosing this part, of course, is the growth of the cyclist.

This is a fairly common question, since from childhood we got used to the fact that buying a bicycle is already a holiday, and few people thought of picking up its parameters specifically for the owner. The main rule in such cases is that the legs reach the pedal. This is not quite the right approach. Improperly selected bicycle frame heights will lead to future health problems, namely damage to the back and knee joints. In addition, each specific frame model has a different effect on the unloading of the elbow joints and joints of the upper shoulder girdle.

Gradually, the discomfort after such trips will outweigh the pleasure, and you will have to say goodbye to your passion. No one wants to lose an interesting hobby because of some annoying little things.

It is hardly possible to choose the ideal ratio of the complete set of a bicycle for a person - in this case, each model will have to be manufactured according to individual parameters, which will make mass production impossible. However, you can determine the most suitable parameters for the main components, and the bicycle frame is one of the most important components.

Criteria such as weight, height and equipment are the same for women and men, but you must remember that there are differences in physique. So, for example, in men the shoulder girdle is often more developed, and in women, on the contrary, the emphasis can be on the thigh area.

therefore different models have a special table that helps to most competently determine the required frame size - size. These tables are rarely divided into female and male, and if they are, then, as a rule, the discrepancies present in them are insignificant. So, a girl can use male sizes if you don’t have time to look for the appropriate plate to find the right bike and vice versa.

Thanks to this, you can find out the optimal size of the frame for your bike. During the search and purchase of a bike in the future, it will be enough just to recall the specific marking and choose a model with the necessary equipment. But do not forget to pay attention to other parameters, for example, the type of bike - mountain, highway, city or hybrid - for each variety there are specific selection criteria.

As mentioned above. The female figure has several differences from the male. Given this, manufacturers of female models create ladies' bikes, in which the distance between the seat and the steering wheel is slightly less than that of the male. For leisurely city walks on warm evenings Focus on the species with a lowered upper pipe. On this model you will feel most comfortable, and on such bikes you can ride in a skirt, dress.

When you decide on the purpose of your bike, you can proceed to the next step - selecting the right frame length suitable for your height. To facilitate this choice, study women's sizes and remember the value that suits you. This will help determine the most significant search parameter. The appropriate marking should be sought on a small tube under the saddle - this is where a significant part of the companies engaged in the production of bicycles have it.

In addition to the growth of a person who plans to use a bicycle, it is recommended to focus on some more parameters. This bike destination is for mountains, a hybrid, for a city. The size of the bicycle depends on the method of operation, and therefore, the size of its individual parts. Do not forget that the dimensions for road, city and hybrid bicycles are written in cm, but the markings for mountain bikes are indicated in inches.

Do not believe those who claim that a suitable wheel size is somehow related to growth. It's a delusion. Indeed, before each model had only a few sizes, which were intended for a specific age group, but now the situation has changed. The primary task is to find the size of the frame that fits your physique. A man of a powerful physique on a bicycle with large wheels will look much more natural, but this is a matter of aesthetics and preferences.

If you need a bike as a means of transportation around the city, relying on its speed, then think about purchasing a model with large wheels that can cover a much larger area than small ones. But do not forget that the larger the diameter of the wheel, the more effort will have to be applied to rotate and the entire movement as a whole.

When purchasing a new bike, test it (with the permission of the seller, of course). If the store’s space doesn’t allow you to ride, then at least try to sit down and pay attention to your feelings - are your hands on the steering wheel comfortable, do you have to stretch and tilt your back too far, is it possible to reach with your feet to the pedals without stretching your toe too much . Measure the distance from the crotch to the upper tube: throw your leg as if you were going to sit down, but do not sit down, but rest against two legs.

The distance from the upper tube of the bicycle to the crotch should be about 5-10 centimeters. If this gap is shorter, then the probability of injury increases.

Again, the purpose of the bike - if you want to professionally engage in cycling, then the frame should be as long and lower as possible. For example, with a high frame and a high landing, you will not go into a steep mountain. Well, if you rarely use a bicycle or just ride short distances every day, you can take the option with a short frame.

But if you increase the load, then the frame will still need to be replaced with a longer one, since with a short frame, almost the entire load falls on the back and spine, which with long loads is fraught with health problems for the cyclist.

If you prefer quiet walks, look for a frame with the help of your characteristics in sizes. The smaller the stunt bike, the easier it is to control it during the maneuver. The frame must be at least 2 sizes smaller than the standard.

There are situations when you have already purchased a bicycle, tested it and suddenly realized that you experience discomfort during operation. I don’t really want to buy another new bike, although this time correctly selected for you, and buying a frame separately will cost 80% of the price of the bike. In such situations, you can try to fix the situation. by adjusting the steering wheel and seat.

The steering wheel is mounted on a special short pin, called "steering wheel extension". It has a certain angle and length. According to whether the bike is big or not, it is possible to adjust the steering wheel offset. If the bike is large, take a short takeaway, and if there is a bike too small, the takeaway is longer. A separate detail is the steering wheel horns. They allow you to change the position of the body as you feel most comfortable.

The best option - horns are installed parallel to the ground, with a small diagonal rise. Models of horns are quite diverse, you can purchase several in order to be able to choose the most suitable position for each type of ride.

To adjust it, rest your foot on the pedal and lower it down. At the very bottom, the foot on the pedal will be slightly bent. If you put the toe of the foot under the pedal, then the leg will straighten. This will be the optimal seat height for your height.

Overweight people often choose models incorrectly. They believe that the larger the frame, the stronger it is, but this is not true. Because of this belief, which has no foundation, bicycles are very often purchased that are completely unsuitable for man. This will cause many inconveniences, so that the pleasure of riding can be forgotten.

The only recommendation for choosing a bicycle design in accordance with its weight is acquire urban or mountain models designed for high loads and having increased strength of the entire structure. Those who need a very durable bike, it is better to look for an option with a reinforced frame. Another argument in favor of a low frame - if you are overweight, climbing a bike with a large and high frame will be uncomfortable.

A special category of frames is spatial for an electric bike. The purpose of this frame is slightly different: a battery and some small parts are attached to it. The ergonomic appearance gives not only the increased durability of this bicycle part, but also helps to hide the entire electric “stuffing”.

Often, these bikes can be assembled yourself by purchasing all the necessary accessories, but just adding the simplest bike to them is not enough. At least it will look ridiculous, and when you try to attach any heavy battery or other power source (with the exception of special batteries) to the frame of a regular bike, you can accurately predict how many trips this whole flimsy design will fall apart.

In this case, it is better to pay attention to which bike you want to receive: fully automated, semi-automated (pedals spin or not spin as you wish), with removable electronics or not. It is recommended to start from the amount of equipment added to the spatial frame when searching for the frame - this affects the strength and durability.

On electric bicycles, the load on the legs decreases, so despite the fact that the size of the frame is still an important criterion, it fades into the background, giving way to strength, durability and technical properties of the battery. But the weight of such a frame is significantly different from the usual bicycle frame - spatial frames are several times heavier. If you expect to place a spatial frame and be able to pedal and ride with your own strength, you are deeply mistaken.

Do not forget that the design of a regular bike is focused only on muscle strength with a small margin, so when assembling an electric bike with a conventional frame as a basis, you greatly risk not only your health, but, possibly, your life. It is better to spend a little more and assemble a bike based on a spatial frame, which is much more durable than conventional and will allow the use of more powerful power sources. So the speed of a bike assembled on such a frame will be significantly higher than the speed of an electric bike assembled on a conventional frame.

If you are looking for a spatial frame, then see in advance the compatibility of the particular model you have chosen and the other necessary components. This is a very important parameter, since some parts can be created specifically for each batch, and when used with parts from other manufacturers or from the same manufacturer, but from a different batch, the entire assembly of an electric bike may cease to function. It is better to find out such things from specialists or on the manufacturer’s websites.

So, if you need a bicycle or a separate frame for your bike, pay attention to its height, and it is better to try the bicycle when buying, since not only your comfort, but also your health will depend on it.When looking for a frame for an electric bike, consider first of all its technical properties and compatibility with other parts for assembly.

And remember that There is no universal bike that can suit all family members of different sizes and ages at the same time. So, if a consultant offers you to purchase such a miracle, give up advice and choose the appropriate model for each one yourself.
