How to adjust the bike to fit your child’s height

Selection features

For children 4-6 years old

For older children, ages 4 to 6, you need to choose options with a size of 16 inches. And the height of the child at the same time varies from one meter to 115 centimeters. They also come with rear support wheels. On these models, there are already two gears so that the child gets used to riding an adult bike. As for the brakes, that is, both hand and pedal brakes, namely, there is a rear foot brake, which is the main one, and an auxiliary one on the steering wheel. There is also the possibility of adjusting the height of the seat and steering wheel, in case the child grows up quickly. When reaching the age of 5.5. 6 years, it is recommended to choose bicycles for children with wheels measuring 20 inches. But, before buying such an option, you need to make sure that the child is already confident enough to ride a two-wheeled bicycle. This is due to the fact that on vehicles, the size of the wheels is 20 inches, no additional auxiliary wheels are already installed. In addition, they are not even included in the kit, since the models are designed for those children whose riding skills are already well developed, regardless of height. The advantages of such bicycles are as follows:

  • They have multiple gear speeds;
  • Rear derailleur;
  • Free pedal travel backwards as the brakes are located on the handlebars, namely on both levers. One of these levers is responsible for braking the front, and the other is responsible for the rear.

In addition, the 20-inch wheel options may already be fitted with suspension forks for greater comfort than rigid forks. In the absence of side support wheels, in order for the two-wheeled vehicle to be parked, a special footboard is attached to it from below. There are also differences in frames for boys and girls in the models. Girls have a slightly understated top tube.

Children’s bicycles called “runbike”.

A separate item is a balance bike. These children’s bicycles can be purchased for toddlers no more than 4 or 5 years old. The runbike does not have a rear and foot brake, and all that a kid can do in order to ride a runbike is to push off with his feet. The wheels of the balance bike, as a rule, have a small diameter, which helps to make the baby’s ride as comfortable as possible.

Useful Tips

There are several useful recommendations to help you avoid mistakes when choosing a particular vehicle for your child.

For children 7-12 years old

Next in size are bicycles on 24-inch wheels. They are designed for children aged 7 to 12 years old, 130. 150 centimeters tall.

Compared to the previous ones, this type has a more developed transmission, that is, there are both rear and front derailleurs.

For children 2. 4 years old

For a small child, 12-inch options are great. Children’s bicycles can be bought for babies from 2 to 4 years old. And for growth from 90 centimeters to one meter. As a rule, two additional rear wheels are included in the kit, which act as a support and help to quickly learn the child to ride a bike on their own. It should be noted that additional wheels can be removed and put back on as much as necessary. Also, they usually have one gear and a brake system installed on the pedal control, the brake is rear foot. For better insurance, you can also brake with the front handle located on the steering wheel. The front brake manual is needed so that the child learns to brake, as in an adult.

Rope length for beginner

If you are a beginner, start with a level 1 length (up to the shoulder) so you have plenty of room overhead and under your feet as you learn the basics of jumping techniques. This length will allow you to stray less often, which is very important for beginners during training.
You can read about how to start jumping rope and what exercises are suitable for beginners in my article for beginners.

Rope length for the amateur

As your physical fitness improves, your movements will become more correct, the amplitude of rotation of your arms will decrease, and you will shorten the rope by level 2 (to the top of the chest).
When you use a shorter rope, there is less room for error, and you have to work more accurately with your arms and legs, this helps to increase the speed of rotation of the rope, which in turn develops coordination of movements and helps to shorten reaction time.
When using a rope of this length, it is more convenient to jump at a faster pace, including double jumps.
Most people jump level 2

Correct rope length

The correct length of the rope is when the cord does not hit the floor hard in front of the feet, resulting in a strong deceleration of rotation and a rebound into the feet. Also, there is no need for a large gap over your head. you can track this parameter by jumping in front of the mirror.
But the most important thing is to choose the length of the rope so that it is convenient for you to jump.

How to choose the length of the rope

People in their workouts often use the most affordable simulator. a jump rope. There are several types of jump ropes and are very different from each other, so you first need to choose the right model.
After you have chosen a rope, you have a question: how long should the rope be??
The size of the rope depends on the height of the athlete, as well as on the skills of working with it. An incorrectly selected rope length leads to more frequent mistakes and forms an incorrect jumping technique.

The general rule can be formulated as follows: The better a person jumps, the shorter his rope.

How To Set Up Your Child’s Balance BIke

But do not rush to shorten the length, follow the rule: measure seven times. cut once.

In order to determine the length of the rope you need:

  • Stand in the middle of the cord with one foot
  • Pull the handles straight up
  • Determine at what height they are

There are three main sizes or levels of length, each of which has a different training effect and is appropriate for a specific fitness level of the athlete:

  • Shoulder-length
  • Up to the top of the chest
  • Down to the bottom of the chest

Rope length table from the height of the athlete.

The length of the rope is counted together with the handles.

Professional rope length

For the most experienced athletes, a Level 3 length (down to the bottom of the chest) can be recommended. This length allows you to achieve the highest jumping speed without sacrificing correct body position and jumping technique. It should be noted that many complex tricks with a long rope are much more difficult to perform than with a short one.
Professional athletes use an even shorter rope when jumping at speed.

Rope length for child

Many parents do not always reasonably leave their children a rope that is too long, as it were, for growth.
If you are adjusting the length of the rope for your child, make it comfortable for him to jump now, not when he grows up. You don’t buy adult clothes for children, no matter how much you would like to save money.
over, in some skipping ropes it is possible to leave part of the cord in the handle and slightly increase the length when required.

Three checks before leaving

Before riding, you need to make sure that all the systems on the bike are working as expected. Mandatory check before skiing is required:

Tires, namely. the pressure in them
For some reason, it is believed that it is more convenient for a child to ride on soft tires, this is not so. Many manufacturers indicate on the rubber how much pressure must be maintained for the most comfortable movement. If there is no such information, for children and adolescents, you can use the data indicated in the table:

Serviceability depreciation
You need to squeeze the brake lever on the handlebars and stagger the bike, resting your finger to the place where the shock absorber fork enters the so-called “pants”. This will make it possible to check for backlash. Also, the plug and the place where it enters must always be well lubricated. When the bike is moving with the brake applied, no sounds, squeaks or clicks should be heard. If there are any, it is better to go to a bicycle repairman with a problem.

Setting gearshift
Before each trip, you need to inspect all elements for serviceability, wipe off dust, dirt and excess oil from the surface of the parts. It is worth taking a closer look to see if the chain slips through several sprockets. If there is such a problem, you need to contact a specialist to configure.

Adjusting additional wheels

If a child has just begun to master a two-wheeled vehicle, he will need additional wheels. They are easy to attach and adjust. This requires:

  • turn the transport upside down;
  • loosen the nut securing the rear wheel;
  • install a bracket to which to attach additional wheels;
  • after checking whether the wheels are at a sufficient height from the ground, tighten their screws;
  • fix and tighten all nuts;
  • check if the chain needs tightening. After attaching additional wheels, it sometimes weakens.

The attached wheels should not constantly touch the ground, because this will make it difficult to avoid pits, puddles and irregularities on the road. But they should not be located too high from the ground, otherwise they will be useless, and sometimes unsafe.

Saddle adjustment

To adjust the seat of a child’s bike, the child must place a two-wheeled friend between their legs. In this position, there should be a free distance between the butt and the saddle.

10-12 cm. This is the most comfortable position. It will be easier for the kid to jump off his vehicle if necessary.

We give the child the opportunity to spin the pedals. The heel should reach her freely in the lower position. Then the legs will not get tired, and the back will not strain unnecessarily.

To set the desired saddle height, you need to unscrew the bolt under the seat near the frame. This will release the pin and the saddle can be positioned at the desired angle. Next, insert the pin into place, and tighten the bolt well. and you can ride.

Adjusting the brake system

Before setting up your child’s bike brakes, you need to make sure they are working properly. To do this, raise the upper wheel, set it in motion and apply the brake. The wheel should stop instantly. If slippage or braking delay is observed, then the braking system needs to be repaired. The same procedure should be carried out with the second wheel to make sure that the brakes are working properly.

To adjust the locking system, you need a set of tools. A complete set is best suited. If there is no such thing, you need to take: screwdrivers (flat and Phillips), a bicycle or wrench and a hexagon. How to make the adjustment. step by step below in the text.

Adjusting the brake lever on the steering wheel
It is necessary to loosen the screw fixing the position with a wrench, and adjust the handle with the screw so that it is pressed on by the second phalanges of the fingers. When a comfortable position is selected, secure it by tightening the screw tightly.

Adjusting the brake pads
They should fit snugly against the rim. To adjust, loosen the nuts that fix the pads with a wrench, and install the latter parallel to the rim so that they do not go beyond its limits. When the adjustment is completed, you need to tighten the nuts again.

Centering the brake levers
To check if the levers are properly centered, you need to press the brake lever and see if both pads are in contact with the rim at the same time. If not synchronized, adjust the cable tension. For this, a locking screw is located on each lever. If one of the brake pads touches the rim before the other, you need to tighten its spring more or reduce the spring tension of the opposite pad.

Done? Now you should check the speed of the brake operation again, and then ride.

How to adjust a kid’s bike: 4 steps

A tuned bike is a guarantee of a comfortable ride for a child. When everything is set for growth, the baby will keep his back straight, and get tired. not so quickly.

Hands will be able to comfortably hold the handlebars to control the bike, and legs can pedal easily. You yourself know that. Therefore, we will figure out how to properly adjust the bike for the child’s height.

Steering wheel adjustment

The child’s bike position should be such that while riding, you do not have to stretch your arms far or bend unnaturally.

The bolt, which is located on its stem, is responsible for adjusting the steering wheel. The bolt must be loosened with a hex wrench before adjusting. Then adjust the height and tilt of the handlebar and tighten the bolt well again.

The indicator of correct adjustment is a flat back and free movement of the knees under the steering wheel. If the feet touch the steering wheel, then the slope and height have been chosen incorrectly. The child will be uncomfortable.

Four common mistakes

Incorrect saddle position
If set too low or high, the back will be uncomfortable.
2. Incorrect steering wheel adjustment

4. 6 years oldup to 115 cm16 inch
7. 9 years oldup to 130 cm20 inch
10. 12 years oldfrom 130 cm24 inch

Growth up to 98 cm. As a rule, this category includes babies aged 1 to 3 years. Bicycle wheel size should be no more than 12 inches.

Height up to 115 cm. This category includes children aged 4 to 6 years. They can already learn to ride a bicycle with wheels in 16 inches.

Height up to 130 cm. In this case, we are talking about schoolchildren (age from 7 to 9 years old). Bicycles for this category of children may have wheels with a diameter of 20 inches.

Height from 130 cm. Here already the child, for sure, has mastered cycling well. But even if this is his first bike, learning will be easy enough when choosing a model with 24-inch wheels. Models of bicycles with 26 ” wheels are also acceptable (bicycles for adults).

How to choose a bike for a child’s height?

Cycling success depends primarily on choosing the right model. Riding a bike, where a child can hardly reach the pedals, can hardly be called comfortable with a claim to success. Quite the opposite: the child will never want to ride a bike again, and the first fall will cause injury and even shock.

Wondering how to choose a bike for a child’s height?

We are ready to help you with the selection with useful practical advice. A child’s height will affect many parameters: wheel diameter, seat height, handlebar height, frame-to-crotch distance. If the height of the seat and handlebars can be adjusted, then there will be special requirements for other parameters.

So, standing near the bike, the distance between the crotch and the frame should be from 5 to 10 cm.Such parameters allow the child, if necessary, to quickly jump off the bike.

Your child’s feet should be firmly on the pedals. In no case should you buy a bike for growth. Fully straight legs on the pedals is not the correct option. The baby’s legs should be slightly bent at the knees, and confident support on the pedals will make it possible to comfortably make their first attempts at independent cycling.

It will be quite easy to choose a bike for a child in terms of height and weight if you use the recommendations below and take 2 minutes to read the important parameters when choosing the parameters below.

What else to look for besides the child’s height?

Growth is indeed one of the most important indicators. The age of the baby and his level of preparation for transferring to his first bike is also important.

Please note that the model you have selected has a high-quality foot brake. For the smallest data, the criterion is important. For children from 7 years old, the bicycle can be equipped not only with a foot brake, but also with a hand brake. The choice of a children’s bike by height will be crowned with success if you pay attention to the models of the best European manufacturers, where the quality of the material and components guarantee a safe and efficient ride for the baby.
