Choosing the size of the bicycle wheels: 26”, 28” or 29”?
One of the most important parts of a bicycle is its wheels. over, it is their size that matters more than weight. There was a time when the bicycle market offered adult cyclists one standard size. 26 inches. The modern market is more diverse and therefore the question arises: which wheel diameter to choose?
Let’s say one thing: there is no definite answer to this question. But we will speculate on this topic. And each of you will take a grain of reason from this reasoning and make your choice.
And let’s make a few more useful Комментарии и мнения владельцев before we get down to reasoning:
the size of the wheels is determined not only by the diameter of the rim, but also by the height of the tire;
size units. English inch. It is denoted. “;
modern manufacturers produce adult bicycle wheels in sizes 26, 27, 27.5, 28 and 29 inches. over, with a wheel size of 26” rim diameter is 559 mm, tire thickness. With sizes 27”, 28”, 29” the rim diameter is the same and is 622 mm. Only the height of the tire is different;
wheels of different diameters
- As already said, 26”- the most common size. It is used mainly on standard mountain models and walking city bikes. 27” used on road bikes. 28”- on hybrid and road. Newest size 29” versatile as it is ideal for both smooth asphalt and problematic dirt roads.
The larger the diameter of the wheels, the more smoothly obstacles in the form of holes, bumps and stones on the road are overcome. Large diameter absorbs small impacts more easily.
The larger the diameter, the greater the grip between the wheel and the road surface, and the safer the ride (especially on slippery and muddy roads). The size of the adhesion area is also affected by the width of the rim. The widest rim. at a value of 29”.
the bike is heavier. Long spokes, wider rims, taller frames and heavier tires
the dynamics of acceleration is lower, since due to the greater inertia and weight during acceleration, you have to apply much more effort;
It should also be noted that for the niner (29”) the choice of some components is limited: rims, tires, forks. This does not apply to the selection of transmission and other little things.
The larger the diameter of the wheels, the more harmoniously the wheels are combined with tall people. 29”. size ideal for cyclists taller than 180 cm.
How to choose a bike for your child
Choosing a child’s bike is a very responsible task. Many factors must be taken into account here: the age of the child, his physical data, stamina, taste preferences, the estimated operating time, design, etc.
A bicycle in childhood is not only a tool for physical development (a healthy child never sits still). it is, so to speak, a means of socialization, one of the ways to interact with peers, because children are not familiar with secular communication, they play, but always seriously! So, choose a bike for the little ones.
How to choose the right bike size for your child? The growth of a child is not a constant value, so it is very difficult to predict anything with 100% accuracy, so to speak, in a transitional moment. We give an approximate table of correspondence (age / height / wheel size).
|24 years||up to 98 cm||12 inch|
|4. 6 years old||up to 115 cm||16 inch|
|6. 8 years old||up to 130 cm||20 inch|
|8. 13 years old||from 130 cm||24 inch|
Understanding Tire Sizes | Tech Tuesday #145
Tricycles are suitable for babies (from 1 to 3 years old). There are many such models on the market today, so you can choose based on material capabilities and taste preferences. However, there are other factors worth paying attention to. The bike must strictly correspond to the growth of the kid, be comfortable, light and safe.
Recently, run bikes have gained popularity. two-wheeled bicycles without pedals for children from 2 to 3-4 years old. The child, sitting on the saddle, pushes off with his legs and due to this moves. Balance bikes help your child learn to maintain balance and easily step over to the next stage of development. to master full-fledged two-wheeled bicycles.
For height up to 115 cm (age 2-6 years), models with a steel or aluminum frame with additional wheels and a wheel diameter of 12-16 inches are suitable. Often these models have foam steering wheel guards, shields that protect against dirt flying from the wheels, and a chain guard that prevents clothing from getting into it. Most often these are single-speed bicycles with foot brakes.
For older children (6-8 years old) up to 130 cm tall, it is best to choose 20-inch wheels. For safety reasons, these bicycles are produced without additional wheels. Some models are equipped with gears and rim brakes. Children happily inherit their parents and are already riding like an adult, choosing the right gear according to the relief of the road.
Is your son or daughter 8 years old and over 130 cm tall? Then your choice is bicycles with a wheel diameter of 24 inches. These are already full-fledged bicycles with gears, sometimes even disc brakes. The frame they have is a little smaller than yours 🙂 Teenagers really like to drive on steep, adult bikes. Do not deny them this!
If the child’s height has exceeded 140-150 cm, you can buy an adult bike with a 14-inch frame and 26-inch wheels.
At the same time, no matter what plans you make about buying a bicycle “for growth”, it is necessary that the chosen one is suitable for the child in terms of height and physical parameters at a given moment, taking into account the various settings and adjustments of the mechanism (saddle height, handlebar height, etc.). etc.).

I recommend that you purchase special equipment for cycling (safety helmet, water bottle, etc.)
How to choose the right bike frame size for your height?
And now we come to the main reason for the discomfort on the bike. frame size
The wrong size of the bike leads to excessive fatigue of the muscles of the back, knee joints, arms and neck muscles.
Naturally, such trips will not bring you much pleasure.
Every modern bike has its own size. Often, one and the same model is produced in several frame sizes, which means that there should be no problems with choosing a bike for your height.
Get on your bike, grab the wheel.
The arms should be slightly bent at the elbows. You should not reach for the steering wheel, and when cornering, your hands should not lose the steering wheel.
If it is a mountain bike or sports bike, then the landing should be slightly tilted on the handlebars; the load is evenly distributed over the back and arms.
On road and city bikes, the seating position is usually with a straight back.
Very important: sitting on the seat with your foot on the pedal in the lowest position. the leg should be almost straight, this will save your knee joints from unnecessary stress.
Stand forward from the saddle. For safety, there should be a gap of 5-10 cm between the inner thigh and the upper tube.
Use this table and you can easily determine which bike frame size you need.
Choosing a bike size according to your height
Bicycle wheel size selection
The size of the wheels of a bicycle determines its overall clearance (the height of the bicycle), and also affects the maneuverability, handling and roll of the bicycle.
Recently, bicycles with 29 “and 27.5” wheels have become quite popular. as a rule, such bicycles belong to the class “mountain bike” (mountain bike).
It is no secret that the larger the wheel of a bicycle, the larger it becomes, and therefore less maneuverable compared to other bicycles, but this does not mean that such bicycles are poorly controlled. But these bicycles go better. roll smoother and more confident, well, the speed will be higher.
26 “wheels are still considered the standard for an adult bicycle, but city, road bikes and hybrids usually have a base with 28″ wheels.
How to choose the right adult bike
And so, now we are faced with the question of choosing the right adult bike.
How to choose the right bike for yourself, where to start?
The first step is to decide which type of bike you prefer:
- City bike. for driving along city streets and bike paths
- Road bike. for fast driving on asphalt roads
- Mountain bike for riding on rough terrain and bumpy roads
- Or maybe even a hybrid, in which there is a little of all of the above types of bike
If you have not decided yet, perhaps this article will help you make your choice: What are the bicycles
Now that we have decided on the type of bike, we move on to the next, but no less important stage.
Now that all the main selection criteria have been taken into account, you can safely go to our bicycle catalog to choose your new two-wheeled pet.
We hope that this information was useful for you, and you will definitely find a bike that is perfect for you.
Wheel size 27.5” or 650B came into the world of MTB from road cycling, more specifically, its children’s department. For young riders who were too big for adults of 28 inches, they made smaller rims, not 700, but 650 mm in diameter. Then this standard migrated to MTB.
The most important criterion, in our opinion, is the cyclist’s height. Recently, many manufacturers have switched to the so-called Size Split system, in which the size of the wheel depends on the size of the frame. frames from 14 to 18 inches have wheels of 27.5 inches, and frames from 17 to 23 to 29 inches. Thus, based on this principle, if your height is not more than 175 cm, then you should pay attention to a bike with 27.5-inch wheels, but also do not lose sight of the 17-frame 29er. Well, if your height is 180 or more, then we definitely recommend the 29th wheel!
29 wheels are less maneuverable than 27.5-inch wheels. If you rode 26 wheels before buying a 29er, then you will need to get used to the unusual behavior of large wheels for you. To compensate for this effect, some bicycle manufacturers put handlebars on niners slightly longer than on bicycles with 27.5 wheels. this is obvious, because a larger wheel, which has a large gyroscopic effect, requires more lever to turn. Wheels 27.5 inches are devoid of this drawback and are close to the performance of the old 26” standard.
The size of the wheels of the so-called niners (from the English twenty nine. Twenty nine) came to us from the world of hybrid bicycles or cross-country (and to them. from road) bicycles. They all have the same rim diameter. 700 mm, the only difference is in the width and increased strength of the rim for 29ers. Well, the size of 29 inches is achieved by installing a wider and taller off-road tire.
Acceleration and roll-forward.
27.5 wheels accelerate faster than 29, that’s a fact. If you need to break away sharply at the start, then 27.5 will help you with this, but the niner will have to spin a little more time. But when a certain speed is reached, the 29th wheels still roll longer and this is especially noticeable at long distances.
Which wheel diameter is better, 27.5 “or 29
Yes, in this article we will raise this issue, the reason for the heated debate on the forums and holivars. What choice, in favor of what wheel size, should a person make, who opened the door to the world of MTB, or just decided to change their old 26er, for something more modern, meeting the increased needs and skills of the owner? First, let’s figure out where these wheel sizes came from.
Which wheel size to choose, 27.5 or 29 inches?
The exact answer. which is better and which is worse. cannot be given here. Everything is individual and depends on many factors, including the level and style of riding, the anthropometric data of the cyclist, etc. Consider the main selection criteria.
Dimensions of bicycle wheels and how to correctly measure the diameter of a bicycle wheel for your height
If you decide to upgrade your two-wheeled vehicle or just change wheels, a logical question arises. which wheel to choose? Regardless of whether you want to buy a wheel the same size as yours, or give preference to something new, you need to be able to determine the diameter of the wheel. And, of course, you need to know what this indicator affects and why wheels of a larger diameter are more suitable for some people, and smaller ones for others.
The relationship between height and diameter
It is wrong to think that wheel size only affects the driving behavior of your two-wheeled vehicle. Growth is also very important here. Consider in what features this is manifested:
It is worth noting that if you are guided by height when choosing a bike and its parts, then you should observe not only the size of the wheel, but also the size of the bike frame, and in some cases, use the stem in addition to create the most comfortable driving conditions. Some experts recommend taking into account, in addition to growth, the length of the legs, because it is they who get tired the most during the movement and need careful care.
Relationship between wheel diameter and driving characteristics
Consider some options for how the size of a bicycle wheel can affect driving.
- The larger the wheel of the bicycle, the more effort and energy it takes to spin it. Therefore, you will have to train your endurance and pump up your legs. But at the same time, the achieved rotational speed will be much higher and better than in the case of a lower.
- Large wheels are easier to use on smooth and level roads. A 29-inch size would work well here. For mountain bikes with frequent stops, go for smaller rims. for example, 26.
- As for the width of the tire, here the passability on difficult areas. for example, stones or rocks. depends on its width. If you choose wheels for just such a case, then give preference to small models with a minimum width of 2 inches.
|Rim diameter in inches||Rim diameter in mm||Matching bikes|
|twenty||406||Kids models, BMX|
|24||507||Old Soviet bikes like Salyut or Altair, teenage bicycles, bicycles for extreme sports|
|26||559||The most common size option often used by standard mountain bikes or city bikes|
|28||622||Old Soviet models of bicycles such as Ukraine or folding Aist, as well as hybrid and road bicycles|
|29||622||One of the latest developments in the field of cycling. Can be used for both advanced mountain bike models and everyday riding|
Which option is better to choose?
If there is no controversy about the smallest wheel sizes, then it really boils about rims with a diameter of 26 and 29 inches. This is one of the most popular sizes, but in fact there are quite visible differences between them, knowing which you can easily choose the option for your bike and body.
- Bicycles with 29-inch tires pick up the required speed easily enough, handle well, just overcome obstacles, handle turns freely. But in comparison with a diameter of 26 inches, such a bicycle on average picks up speed only with a large expenditure of energy, so it takes more time to circle.
- The 26-inch wheels are more agile in action, pick up speed much faster and stop more easily. But as for inertia, here the rim with a diameter of 29 inches takes the palm.
- If you are looking for the option to tackle various bumps, then 29-inch wheels are your option. Since they have a large area of contact with the surface, you will overcome bumps without even noticing them. Also, driving up a steep incline will give you much less inconvenience if the rim size is larger. Accordingly, on a bicycle with a wheel diameter of 26 inches, you will need to expend more energy and strength to overcome obstacles.
