How To Adjust The Bicycle Seat For A Child

Detailed instructions: how to properly adjust the bike seat

A comfortable fit while riding a two-wheeled vehicle allows you to avoid premature fatigue, numbness of the hands, damage to the knee joints. A modern bike is customizable for the owner in various parameters, which provides maximum comfort for any user. In the current article, we will consider how to correctly adjust the seat on a bicycle for height, tilt and seating depth.

The importance of tuning

There are three parameters for seat adjustment on a bicycle:

  • height above the pedals;
  • horizontal tilt;
  • steering offset (closer, further).

A correctly adjusted seat position eliminates any negative effects of cycling on the body. The person will not get tired quickly, the legs will work normally, and in the event of an unexpected stop, it will be possible to quickly reach the ground. To ensure a proper fit, the setting must be combined with the height and tilt of the bike’s handlebars.

The horizontal tilt determines the level of stress on the arms and lower back. The standard position is parallel to the ground, however some cyclists need to tilt the seat 3-5mm to feel more comfortable in a two-wheeler.

In addition to the adjustments mentioned above, you need to take care of the comfort of the fifth point even at the stage of buying a bike. The optimum seat width is different for men and women. You can calculate the parameter by the ischial tubercles. To do this, you need to sit in the sand and measure the distance between the two deepest points.

With an indicator of 10 cm, a saddle with a width of 13-14 cm should be selected. If the distance between the grooves is 12 cm, then the seat should also be 3-4 cm wider. The universal saddle is 14-14.5 cm wide. it can be used by all riders without exception. However, maximum convenience is achieved by personal selection.

Correct bike seat height

The first step is to find the optimal seat position in the vertical plane. The height is selected depending on the height of the person and the riding style. Before the procedure, you need to consider safety aspects:

  • the seatpost does not protrude beyond the critical mark, otherwise the saddle may pop out during movement;
  • the seat must be firmly fixed at the selected height so that it does not shift down during the ride;
  • the saddle must not be installed backwards to the front. the narrow side must necessarily look at the handlebars.

The adjustment itself is carried out according to the following general scheme:

  • The pipe into which the seat is inserted has a clamp, eccentric or clamping nut. They need to be slightly loosened.
  • While holding the seat, deepen or raise the seatpost higher.
  • Tighten the mount. Press the saddle down with your hand to perform the first check for firm hold. If everything is in order, you can climb on the bike and jump a little, imitating movement on an uneven surface. the seat should not go down.

The correct seat height on a bicycle is determined by several methods:

  • mathematical calculation;
  • adjustment for a slightly bent leg;
  • heel adjustment.
  • The first method does not require much effort, but it is not 100% accurate. It can be applied for the first adjustment, followed by adjustments with the two remaining methods. The bottom line is as follows:

    • Measure the distance from the foot to the crotch.
    • Multiply the resulting value by 1.09.
    • The final figure indicates the distance from the pedal in the lowest position to the top of the seat.

    The second option for determining the height is the most common and reliable:

    • Climb a bike with a support nearby.
    • Put your foot on the pedal and roll it to the bottom position.
    • In this position, the leg should be barely bent at the knee. If it does not reach the pedal, the height decreases, if it is too bent, it increases.

    The third option, heel adjustment, involves a similar sequence of actions. The only difference is that you need to navigate by the fully extended leg:

    • Scroll the pedal to the bottom point and put your heel on it (the toe hangs down).
    • Adjust the height of the seat so that the leg is completely straight in this position. Accordingly, with the normal position of the foot on the pedal, the leg will be slightly bent.

    Tilt angle adjustment

    Continuing to figure out how to properly adjust the bike for yourself, you should pay attention to the seat tilt. In most cases, the user is comfortable enough when it is strictly parallel to the ground. If the saddle is tilted towards the handlebars, the load on the arms and hands increases, the back humps, and the butt slides forward. Leaning back leads to rapid leg fatigue and poor bike control.

    However, sometimes you need to slightly change the position angle. For example, on difficult terrain with a lot of obstacles, arms will bounce even with good shock absorbers. To reduce the load, you can tilt the seat back slightly. For better wind handling when tilting the body, tilt the saddle wisely. It is recommended to make angle changes within 10 °.

    Offset (depth) setting

    Moving the saddle closer to or further from the handlebars is done to compensate for the varying arm lengths of cyclists. Correct centering improves the controllability of the two-wheeler, and the rider feels better when leaning.

    The recommendations presented in the material will help you understand how to properly install a saddle on a bicycle for a comfortable ride without harm to health. It is important to consider the seat width when buying. Further adjustments are made to the height, tilt and depth of the saddle position.

    How to properly adjust the bike seat. How to properly fit and adjust a saddle on a bicycle

    Cycling is designed to tone all muscle groups, lift your spirits and improve your quality of life. An important role is played by the technical condition of all components of the bike and its setting. Individual fit for the cyclist is carried out according to several parameters, in particular, the position of the saddle.

    The saddle setting determines the fit, handling and ride efficiency. Let’s consider how to properly adjust the saddle so that it is both comfortable and not tired after long trips.

    Why adjust your bike saddle

    The bike seat can be adjusted in three directions:

    • height above pedal level;
    • angle of inclination in the horizontal plane;
    • bias.

    Let’s consider what the correct adjustment of each parameter gives.

    The height determines the position of the legs when driving and the efficiency of pedaling. A low saddle contributes to strong bending of the legs, their rapid fatigue and low pedaling efficiency. Too much height will impair the grip of the shoe and the handling.

    The position of the saddle corresponding to the height eliminates all negative consequences, makes it possible to rotate the pedals for a long time without significant fatigue and loss of energy, and will allow you to quickly reach the ground with your foot in parking lots and in emergency situations. And when combined with the adjusted handlebar position, the seat height will ensure the rider is properly seated.

    The horizontal tilt determines the load on the body parts. The forward position will increase the stress on the arms and move the body towards the handlebars. The tilted seat back will raise the upper body, shifting the force center towards the lower back and abdomen.

    On some bicycles, the saddles also adjust horizontally relative to the center of the seatpost. When choosing the right position, the length of the arms plays an important role. If it’s hard to reach the steering wheel, the seat moves forward a little. With constant hand fatigue, it is worth moving back. On long mountain bike rides, this parameter can be adjusted several times depending on the riding conditions.

    Correct tuning rests on three pillars: comfort, efficiency and reduced steering fatigue.

    Seat height adjustment

    Height is the most important parameter that each cyclist sets independently, taking into account height and riding habits. Before we start adjusting the height, let’s take a look at a number of safety aspects:

    • the seatpost must not be extended beyond the maximum mark;
    • the saddle must be firmly fixed in this position;
    • the front end must face in the direction of travel.

    General setup scheme:

    • Loosen the eccentric or clamping nut.
    • While holding the seat, gently pull out or push in the pin.
    • Without letting go, tighten the mount.
    • Check the fixing strength with a few light blows.

    There are several ways to set the saddle level:

    • numerical calculation;
    • almost straight leg method;
    • Heel method.

    The first option is the easiest way to set the seat height above the carriage. With the help of a measuring tape or tape measure, the height is changed from the sole to the groin. This value is then multiplied by 1.09. For example, the leg height was 65 cm, which means that the bicycle seat should be located above the pedals at the level of 71 cm.It should be noted that this method is approximate and will not be suitable for those who rely only on their own feelings.

    The second method for setting height is to determine the bend of the leg. An almost straightened leg at the lowest point is characteristic of the correct position. The leg is completely straight. the seat post goes down into the tube. The leg is bent strongly. lift the saddle up. Increase the height gradually, especially for the first time.

    The straight heel method is the opposite of the previous one, but it also allows you to set the level of the saddle. Setting sequence:

    • Secure the bike firmly or have someone else hold the handlebars.
    • Sit down and put your heel on the pedal at the lowest point.
    • Adjust the height so that the leg is perfectly straight.

    The heel must be firmly fixed in the center of the pedal. Both legs should be extended in the lower positions. If the heels do not reach, and you have to bend down, the saddle must be lowered. On the contrary, if the leg is even slightly bent at the knee, raise.

    Tilt angle adjustment

    The standard, generally accepted and correct position of the seat in the horizontal plane is parallel to the road. Manufacturers recommend leaving this position and not resorting to slopes unnecessarily. Actually, from the illustration, it is clear that the saddle cannot be deflected at a large angle.

    In the first case, the load on the arms increases, the cyclist hunches down and can slide forward. Tilting the seat back adds fatigue to the legs and impairs handling by extending the arms.

    However, within reasonable limits, the tilt adjustment can be carried out individually. Most often this is required by the specific conditions of mountain biking. On uneven terrain, where the arms are bouncing even with a good shock absorber, you can level the load on them by tilting the saddle back. When a low seating position is required (overcoming the wind, for example), it makes sense to tilt the seat forward. The recommended tilt range is no more than 10 degrees in each direction.

    Horizontal adjustment

    Adjusting the saddle in relation to the handlebars allows you to set the position according to the length of the arms. Correct centering has a positive effect on bike speed and handling.

    The work should be performed in the following sequence:

    • Loosen the screw securing the pin to the seat.
    • Move the seat.
    • Lock the mount.
    • Sit on the bike and check the knee position. It should be located strictly vertically with the pedal axis. The foot is checked on the pedal at the lowest point. If knee protrudes noticeably forward, re-adjust.

    This type of setting is only done after adjusting the height.

    The combination of correctly set parameters of the saddle, taking into account the physiological characteristics of the cyclist, will help to avoid excessive fatigue of the arms and legs, will allow you to be in motion for as long as possible and will have a positive effect on the comfort of control.

    How to properly align your bike saddle

    If you have already picked up and bought yourself a saddle after studying the theory or our article, then it’s time to move on to practice, namely, to correctly install the saddle on the bike. There are 3 parameters for which you need to set the saddle.

    Seatpost Height

    Saddle angle

    Saddle longitudinal position

    I would like to note that the initial installation of the saddle will be only approximate, in any case, you will have to learn everything in practice. That is, they set the saddle in a certain way, rode, remembered the sensations, edited the fit.

    Seatpost Height

    You’ve probably paid attention to other cyclists, or rather to how they sit on their bike. The seatpost is lowered almost to the end, the knees work at a bend of about 90 degrees.

    And it’s okay if they are representatives of stunt disciplines, because they need maximum control over the bike and the absence of obstacles in the form of a seatpost and saddle. But if a person just drives in this position, then at best his muscles get tired very quickly, at worst they suffer, and then knee joints begin to hurt.

    To avoid this, we attach the saddle to the seatpost parallel to the ground, put the pedal in the lowest position, sit on the bike, put the heel on the pedal.

    In this position, the leg at the knee joint should be fully extended. Accordingly, if this is not the case, then you need to raise the seatpost, but do not overdo it. After all, if you lift it too high, then you will shift from side to side on the saddle, in addition to everything, numbness of the tips of the fingers may begin.

    When you press the front of your foot on the pedals, the knee should not fully extend.

    Saddle angle

    Having set the seat in height, we begin to play with the angle of inclination. Too much forward tilt of the tip of the saddle causes great discomfort. the load on the arms is seriously increased, and you will constantly slide down. Accordingly, when the saddle is pulled back too far, it will press too much on the soft tissues of the perineum, which can lead to numbness. Therefore, the initial position of the saddle must be parallel to the ground.

    After riding the saddle set in this way, remember the sensations and adjust the incline if something does not suit you. For example, the crotch has started to go numb, or you feel decent discomfort. tilt the tip of the saddle literally a couple of millimeters down and try to ride again. There are saddles with a bend in the middle, which can be very comfortable when set up correctly.

    Saddle longitudinal position

    Many saddles have dots or rulers to help you remember the saddle position.

    The saddle alignment technique is an imaginary straight line between the kneecap and the pedal axis. With this technique we determine the correct longitudinal position of the saddle. To do this, you will need to set the pedals parallel to the ground, put your foot on the “front” pedal, see the position of the knee relative to the pedal axis in the mirror.

    You can ask a friend to take a photo and then analyze it.

    You can attach a small weight (key, handle, etc.) to the rope, lean it against the kneecap and estimate the position relative to the pedal axis.

    Fitting and adjusting a bicycle seat

    You choose your bike and naturally want to ride it in comfort. One of the most important elements of a comfortable ride is the seat. Agree, if it is uncomfortable to sit on a bike, then what kind of trip can we talk about? This is no longer a trip, but a complete mockery of the body.

    We will focus on a few points regarding the choice and correct setting of the seat (also called a saddle) that you need to pay attention to when choosing a bike.

    It can appear beautiful and comfortable in photographs on the Internet or when viewed from the outside. But, most importantly, you need to sit on it. And not just sit down, but sit down and twist the pedals, or even better, drive, carefully listening to your feelings, both in the whole body and in the place where you sit.

    Take your time trying on the seat. A one minute landing and a long ride make the same difference as a passionate kiss and a long family life. If you (and your butt) feel comfortable on it, then this is your saddle. If not, you can ignore all the other elements of this bike. it is no longer yours. Well, or right away, look for a new saddle for yourself and change the installed one. However, keep in mind that even a great and expensive saddle, not properly installed, will not create any comfort. Therefore, before you sit on it. adjust the seat correctly.

    How to do this we will now and consider.

    Seating a cyclist on a saddle.

    First of all, let’s define how we sit. The main body weight is distributed between the two ischial tubercles (ischial bones). they are the supports for the body, and not soft tissues, as many believe. Just if the seat is too narrow, then the entire body weight will not be on the ischial bones, but on soft tissues. In this case, the blood vessels in the perineum will be squeezed, the blood supply will be disrupted, and you will get a lot of unpleasant sensations after a few kilometers of the trip. In this illustration, the red arrows show the seat and bumps that account for approximately 70-75% of the load.

    In the figure below, the red circles show the areas for the support of the ischial tuberosities. Note that they must be long enough to provide a slight back and forth movement when riding. The sides of the spout should not protrude, and the spout itself should be sufficiently long and narrow.

    Turning the pedals on a seat that is too wide will rub the crotch and inner thighs, which will not add pleasure on a long trip, especially in hot summer.

    If you are going to ride a bicycle slowly and imposingly across the park with a friend or friend, then a wide seat will suit you. Very often they are installed on urban models. If you are going to make long and long trips on your iron horse, pay attention to the narrower saddle. They are almost always installed on mountain or high-speed models.

    I would also like to dwell on the women’s seats. The fact is that the pelvic bones of women are constitutionally wider than that of men. If in adolescents and men it is on average 90.120 mm, then in the beautiful half of humanity it is 130-132 mm. Differences in the structure of the male and female pelvis are also shown in the following figure.

    So not every girl or woman can ride a narrow male seat for a long time. On such a trip, it will create discomfort, and in the worst case, it can come to pain. On average, a classic women’s seat is wider than a men’s one, they have a shorter nose, for a comfortable ride in a skirt, and more original colors.

    How to find out the distance between the ischial tubercles?

    We will offer you two options:

    The first method is shown in the figure to the right. Sit on something soft that keeps its shape or in sand and measure the distance between the roughest points.

    Or the second way, shown in the picture below:

    • Take a sheet of corrugated cardboard or just a thick, but not very rigid, packing cardboard. You can take a piece of cardboard and peel off the top even layer, so that the top layer with the wave remains.
    • Lay it on a flat, hard surface and sit on it
    • Press your ass tightly against the chair so that dents remain on the cardboard.
    • Circle the dents and find the center in them
    • Measure the distance between the centers. this will be the distance between the sital tubercles.

    The fifth picture just shows how much you need to add centimeters to the width for which type of ride.

    There are also special devices that allow you to quickly and easily measure the distance between the ischial tubercles, both mechanical and electronic.

    The principle of operation is the same as described above. The cyclist sits on a special soft cushion of the device. It crumples, and the pillow material holds its shape for a while. Using a special ruler, the distance between the maximum dents remaining from the ischial tubercles is measured.

    In electronic it is even easier. The biker sits directly on the measurement area on the device and the desired distance is displayed on the board.

    The most universal saddle width, comfortable for men and women (especially if a husband and wife use the same bike), according to many experts, is 140-145 mm.

    As you can see from the picture above, the width of the saddle, as well as the ratio of the height of the saddle and handlebar, fundamentally affect the fit of the cyclist and, accordingly, the style of riding from racing to walking.

    Check that the seat cover is not slippery, otherwise you will constantly fidget on it during the trip.

    Seat position adjustment

    Setting up the optimal fit of the cyclist begins with the correct alignment of the saddle, and then adjust (or select new ones) the stem and the handlebar itself (taking into account its rise, width and bend).

    This process involves not only the seat itself, but also the seatpost, and, if necessary, change the connecting rods. The position of the saddle is changed to obtain the correct position for the movement of the legs. The most important thing here is the knees. If set up incorrectly, the load on them will be too strong, which will lead to quick fatigue and pain.

    One of the main mistakes beginner cyclists make is trying to set the saddle too low, mistakenly believing that if they fall, they will have time to get to their feet quickly. In this position, they pedal as if they were constantly squatting. At the same time, not only the legs, but also the knees experience much greater loads than is necessary for normal riding.

    Often the cause of quick fatigue and pain in the pelvic and groin areas is improper seat height and tilt adjustment.

    Saddle height

    The height of the saddle must be chosen so that the heel of a slightly bent leg can reach the pedal in its lowest position. In this case, the upper surface of the toe can touch the lower surface of the same pedal. This can be clearly seen in the figure.

    When the pedal is at its highest point, the thigh of the leg mounted on it should be horizontal or slightly tilted towards the ground.

    By the way, please note that the seatpost cannot be pulled very high out of the seat tube (above the special mark on the seatpost). It must remain inside the pipe for at least 10-15 centimeters, otherwise the pipe will simply break over time due to constant heavy loads on its upper part. If the length of the pin is not enough. buy a longer one or choose a bike with a different frame.

    Saddle tilt

    Ideally, the saddle should be installed strictly horizontally to the ground surface, plus or minus a few millimeters up and down, so that it is comfortable. The nose lifted up by more than a few millimeters will press on the organs of the perineum. With the nose tilted down. the cyclist will constantly slide forward, resting his hands on the handlebars.

    Saddle displacement back and forth, or what should be the distance between the handlebars and the saddle

    It’s great when the bike saddle mount allows you to move it closer to or further from the handlebars. This is usually done with special screws under the seat.

    Often such fastenings are also called rail fasteners. This is due to the fact that the saddle itself can be moved along the guides like on rails with the help of fastening screws.

    It is considered correct to adjust the seat so that, with horizontally located cranks, the knee of the front leg is above the pedal axis plus or minus 1-2 centimeters, depending on individual characteristics. There is another reference point: the distance between the toe of the seat and the stem of the handlebars is the distance from the elbow to the tip of the extended middle finger (plus or minus a couple of centimeters, taking into account the individual characteristics of the cyclist).

    There is a little nuance when driving off-road. If you move the saddle just 2-3 cm back, you can press harder on the pedals.

    We’ve covered the basics of adjusting a bicycle saddle.

    I would like to note a few more points:

    • If there is a manufacturer’s manual for the bike or seat you are buying, read it. Perhaps the manufacturer indicated there about the subtleties and tricks when setting up this particular model.
    • Another non-standard, but useful function for cycling, was offered by Seatylock. Their saddle can easily turn into a bike lock. The multi-fold system allows the wheel and frame to be fastened together and attached to the post.

    And most importantly, when tuning your saddle, remember that you will ride it. Believe me, the body itself will tell you correctly or not, everything is set up and matched.

    Detailed instructions: how to properly adjust the bike seat

    A comfortable fit while riding a two-wheeled vehicle allows you to avoid premature fatigue, numbness of the hands, damage to the knee joints. A modern bike is customizable for the owner in various parameters, which provides maximum comfort for any user. In the current article, we will consider how to correctly adjust the seat on a bicycle for height, tilt and seating depth.

    The importance of tuning

    There are three parameters for seat adjustment on a bicycle:

    • height above the pedals;
    • horizontal tilt;
    • steering offset (closer, further).

    Important! The main and most important is the height adjustment. If the saddle is too low, this leads to excessive bending of the legs, in turn, the muscles quickly fatigue, and the pedaling efficiency is low. In addition, the knee joint performs cyclic amplitude oscillations that are not characteristic of the body. If the rider pedals in a low position, it can be compared to constantly walking on half-bent legs.

    A correctly adjusted seat position eliminates any negative effects of cycling on the body. The person will not get tired quickly, the legs will work normally, and in the event of an unexpected stop, it will be possible to quickly reach the ground. To ensure a proper fit, the setting must be combined with the height and tilt of the bike’s handlebars.

    The horizontal tilt determines the level of stress on the arms and lower back. The standard position is parallel to the ground, however some cyclists need to tilt the seat 3-5mm to feel more comfortable in a two-wheeler.

    Good to know! The saddle offset determines its distance from the handlebars. It all depends on the length of the arms: if it’s hard to reach the steering wheel, the seat moves closer and vice versa. On long trips, the parameter can be periodically adjusted based on the travel conditions.

    In addition to the adjustments mentioned above, you need to take care of the comfort of the fifth point even at the stage of buying a bike. The optimum seat width is different for men and women. You can calculate the parameter by the ischial tubercles. To do this, you need to sit in the sand and measure the distance between the two deepest points.

    How to install a seat on a bike?

    The correct seat height is important for a comfortable ride, travel speed and avoidance of injury. Fortunately, saddle fitting. in most cases, a fairly straightforward process. A few simple steps and you’re done!

    Saddle height adjustment

    The correct height ensures comfortable interaction with the pedals. If the hips are static and do not swing back and forth to reach the bottom of the pedal travel, then everything is fine-tuned. When the leg is at the lowest point during pedaling, the knee should be slightly bent, not extended or, conversely, bent.

    • The knee should be bent about 25 degrees. Like in a sports position. a little fold is enough.
    • If there is nothing to measure, use this formula to manually adjust the seat height: the knee is slightly bent, the hips are static while riding, and the ability to pedal comfortably.

    Measure “inner seam”. This is the distance from the crotch to the floor, measured along the inside of the thigh, as if you were measuring the inside seam of your trousers.

    • Hold the spine of a hardcover book between your legs, simulating a saddle seat.
    • Place your feet apart at a distance of 15 cm
    • Measure from the spine of the book to the floor. This will be the length of the seam.
    • Multiply this figure by 1.09. The resulting number. the distance in inches that should be between the bike seat and the axis of your pedals. For example, the length of the seam. 29 inches (73.7 cm) times 1.09 equals 31.6 inches (80.3 cm). Thus, the gap between the saddle and the pedal axis will be 31.6 inches (80.3 cm). (This indicator can also be calculated in centimeters).

    Learn how to adjust the seatpost. It is usually loosened and adjusted at an intersection with the bike frame. The eccentric lever on the seatpost can be opened with a pry bar and manually set. If there is a small bracket with a screw, it is a bolted seat post: use a socket wrench or adjustable wrench, loosening the bolt just enough to pull the post out. 4. Set the seat to the height you measured. Raise or lower the seatpost gently to the ideal height. Make a mark on the post so you can find it next time if the seat slips or someone uses your bike. 5. Tighten the seat firmly. Or push the eccentric lock lever fully down. Alternatively, tighten the bolts with a socket wrench or an adjustable wrench until they stop loose.
