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.
- 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 a 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 of setting the height is to determine the bend of the leg. For the correct position, an almost straightened leg is characteristic at the lowest point. 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 the first time.
The straight heel method is the opposite of the previous one, but it also allows the saddle to be level. 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.
Correct foot placement using the heel method
The heel should 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.
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;
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 allows 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. A 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 in relation 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 a little forward. 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.
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.
tilt to the steering wheel, 2. the deviation of the saddle from the steering wheel, 3. initial position.
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 areas, where the arms are bouncing even with a good shock absorber, the load on them can be leveled 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.
How To Perform A Basic Bike Fit
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, according to 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.
Adjusting the saddle in relation to the handlebars allows you to adjust the position according to your arm length 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 the knee protrudes noticeably forward, re-adjust.
This type of setting is only done after adjusting the height.
The combination of correctly set saddle parameters, 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.
To make the assembly process as simple as possible, it is best to use special stands on which you can fix the bike frame. If you do not have such a design, then you should contact someone for help who was able to hold the frame, as well as any other components and assemblies, so that it would be easier for you to carry out all the manipulations.
The first thing to do is to open the box, take out all the contents and cut the plastic clamps (ties) with which all the parts are attached to the frame. This is done in order to prevent any parts from being lost during transportation.
After all the parts of the bike are detached from the frame, they should be conveniently laid out side by side. Then it is necessary to remove the remnants of film, cardboard or foam rubber. It is important at this stage to pump up the wheels right away. This is important from the point of view that when the pressure in the wheels changes, the rim can play a little, which, in turn, affects the brake setting. Pay attention to the side of the tire for the recommended pressure. If there is no such inscription, then feel free to pump up to 3 atmospheres, this value will be quite enough.
A hex wrench is required for all operations. With its help, it is necessary to carefully unscrew the plug stem cover, under which there are cardboard rings. They hold the plug in place. They must be removed, and a stem must be attached in their place. It may happen that the stem does not fit the stem. Do not be upset, the problem is solved with a hex wrench. All you have to do is loosen the clamp of the stem side bolts slightly. When unscrewing the side bolts, be sure to make sure that the stem does not fall down, as this will entail a difficult procedure not only to search, but also to install bearings.
After the stem mounting process is completed, it is necessary to replace the stem cover and secure it. For this, a bolt is provided in the design. It is important to note that it is not worth tightening this entire structure too much, since the goal is not to fix the take-out, but to collect all the elements into a single unit. But the takeaway itself should be fixed quite rigidly.
In order to install the steering wheel, you need to unscrew the front stem cover, set the steering wheel in the desired position and screw the cover back. In this operation, the additional hands of someone from your close relatives or friends will be very helpful. In order not to be mistaken with the position of the steering wheel, look at it carefully. The risks located on it will help you to set and fix the steering wheel correctly. The handbrake levers should be positioned so that they point forward in the direction of the bicycle and have a slope of 30-45 degrees. At the same time, pay attention to how the cables are located and whether they are mixed up with each other.
Frame and Fork Adjustment
To assemble the bike yourself, you also need to take care of the frame and fork. Standard bolts and hexagon are used to install the adapters. After that, you need to fasten the shirts of the cables and hydraulic lines. It is necessary to check the alignment of the calipers in relation to the brake rotors so that the wheels rotate freely, without friction of the pads. To do this, loosen the bolts a little and push the brake lever, this must be repeated until the friction disappears.
Inflating and installing wheels
The first thing to do to assemble a bike is to tackle the wheels. They need to be inflated to the recommended pressure. We recommend taking the average value between the upper and lower pressure threshold, which is indicated on the tire itself. The type of bike and riding style are also taken into account. To pump up the wheels, you will need a bicycle pump, preferably with a pressure gauge that allows you to accurately regulate the pressure in the rubber. For disc brakes, brake rotors must also be attached to the wheel. They can be installed directly on the bike or go separately. Many manufacturers install the rear wheel at the factory and adjust the speed switches, but this is not always the case, you can also find completely disassembled models when you need to assemble a bike from scratch. The wheels are attached to the frame with eccentrics or simple nuts. To tighten the nuts, an open-end wrench is useful. Installing a bicycle wheel includes the following steps:
- turn the bike over;
- pull the bike derailleur back;
- insert a bicycle wheel into special holes called dropouts;
- check that the axle is level in the frame;
- pressing the adjusting nut by hand, insert the eccentric;
- close the lever by locking the wheel.
It is important to correctly calculate the tightening force of the nut and the clamping force of the lock from the eccentric. In this case, the eccentric lever must point up. When the bike is moving, it will be on the left. You need to tighten it not weakly, but not excessively. The front wheel is also assembled.
Where to begin?
The bike in the box is well packed, so you need to remove it with a simple stationery knife. Work should be done slowly so as not to scratch the bike. To pack compactly, many elements are connected with plastic clamps, which are easy to bite with ordinary wire cutters. After the main parts have been unpacked, you need to get additional accessories and parts, the set of which depends on the type of large, the level of its equipment, and the manufacturer. These include: brake rotors, fenders, bell, mounting bolts, pedals, and a technical data sheet for the bike. To assemble the bike in parts, it is convenient to use a special bracket-bracket on which you can place the bike. But if it is not there, it is quite possible to do without such an accessory, you need the help of a friend.
Features of the installation of the steering wheel
Installation of the steering wheel. the next step, which will help to assemble a bike from components. To do this, you will need to perform the following actions:
- The stem cover, which is attached with four bolts, must be carefully removed.
- Insert the handlebar into the stem that is pre-centered using the marked marks.
- Tighten the bolts on the stem cross-to-cross. In this case, you should not apply great force, the bolts should be tightly tightened, but not as tight as possible.
- Check how tight the bolts located on the stem attached to the bicycle fork rod are tightened.
The position of the brake levers relative to the steering wheel also plays an important role. They should be placed so that the palms do not bend in the hands.
How to assemble a bike?
Many bicycles that come from the manufacturer come to the customer pre-assembled, but this is not always the case. Many people are interested in the question of how to assemble a bike yourself and spend a minimum of time? We have prepared detailed instructions for assembling the bike, in which you will find the answers.
Tools to assemble your bike by hand
- multitool or set of hexagons;
- 15 open-end wrench;
- stationery knife.
When choosing a multitool, pay attention to the quality of the material and the number of keys. Such a versatile tool will help you set up and repair in the future is great. You also need to prepare a pump for inflating the wheels. When all the tools are collected and the bike is in the box in front of you, it remains only to figure out where you can assemble the bike. This can be done right in the apartment, on the street, in the garage or bike workshop.
Saddle adjustment and pedal installation
Assembling the bike also includes adjusting the saddle and installing the pedals, which may be included. The saddle should be parallel to the ground with the nose along the top tube of the frame. This will help reduce fatigue while riding and prevent injury to your knees. There should be no sideways deviations. Before riding your bike, you need to set the correct saddle position and height. It’s easy to do this way:
- Sit on the bike and straighten your leg, it should reach the pedal with the heel.
- When the crank is parallel to the ground, the knee should be bent perpendicular to the ground and in line with the pedal axis. You can adjust the position by moving it backward or forward.
We practically managed to assemble the bike from spare parts, all that remained was to put on the pedals. To install them, an open-end wrench is used. It is also important to consider the labeling. R is the right pedal and L is the left. The first is worn on the cranks in a clockwise direction, and the second. vs. As you can see, assembling a bike out of the box is not so difficult if you do everything correctly and according to the instructions. Before the first trip, we recommend that you check each installed component again and you can safely hit the road.
Stage two. assembly
The saddle is mounted to the seat post using a hexagon. It is better to adjust and customize for yourself at the very end of the assembly. There must be a reflector next to the saddle.
Be sure to untangle the brake and derailleur cables before installing the handlebars.
The eccentric (in the hub) is responsible for the correct positioning of the front wheel. The procedure is as follows: first, the eccentric is inserted, then the wheel. Remember to release the front brake. Tighten the eccentric until it begins to close with force.
Moving on to the pedals. They are labeled as right and left. Twist in the direction of the vehicle.
Stage one. unpacking
Open the box carefully. Remove the protective packaging from all parts. In the standard factory configuration, the base is already assembled: the rear wheel, steering column, chain, etc. are installed on the frame. You need to replace the steering wheel, front wheel, fix the seat and pedals. Lay out the parts immediately in the order of assembly:
- steering wheel,
- front wheel,
In the box you will find the assembly instructions from the manufacturer. It is specially prepared for your model, so you should focus on it. In this material, we will only highlight the main points.
How to assemble and set up a bike out of the box?
How to turn a construction set from separate parts into a full-fledged sports bike or city cruiser? We bring to your attention detailed instructions.
How to turn a construction set from separate parts into a full-fledged sports bike or city cruiser? We bring to your attention detailed instructions. With minimal tooling skills, you can do as well as a bike shop. By the way, about the tools: a basic set of keys and hexagons, a screwdriver (cross), wire cutters and pliers are enough for assembly.
Stage three. adjustment
Before the first ride, you need to adjust the front and rear brakes, adjust the switches. Check if it is comfortable for you to reach the brake levers. They can be repositioned using the screws on the handles. The bike brakes themselves are located exactly at an equal distance from the rim, if this is not the case, adjust the design with the bolts on the cable mount. Put the brake levers to the test and adjust them to the perfect balance.
It remains to check and configure the switches. Adjustment is needed if, during testing, interruptions in the movement of the chain along the sprockets are noted. If everything is done correctly, the chain will be positioned and move evenly, without distortion.
