What are reflex angles?

A reflex angle is the larger angle, it’s always more than 180° (half a circle) but less than 360°  (A full circle). It’s possibly the most confusing of the angles because it’s always on the outside.


There are six types of angle in total;

An Acute angle is the smallest, measuring more than 0° but less than 90°.

Next up is a Right angle, also taught as a quarter turn. This angle always measures 90 °.

An Obtuse angle measures more than 90° but less than 180°.

A Straight angle or a half turn is always 180 °.

Reflex is the next largest measuring more than 180° but less than 360°.

We then have a full rotation or full circle at 360°.

If you struggle to remember the different names of the angles, try watching this video. The angles are introduced as different characters within a family which might help you to remember!

First, make sure that it is the reflex angle you’re being asked to measure! Lots of children mistakenly, but very carefully measure the wrong angle. Usually, the angle you’re being asked to measure will have a little circle drawn around the point to show you which side needs measuring.

 

You can measure the reflex angle in one of two ways; either measure the inner angle and subtract it from 360° (to give you the measure of the reflex angle) or measure the reflex angle itself.

A reflex angle is probably the trickiest angle to measure because it will be larger than your standard 180° protractor so you’ll need to do a bit of accurate drawing.

 

  1. Line up your protractor with one side of the angle (in this case y to z), make sure that the centre of the protractor lines up with the centre point of where the two lines meet. (N.B Lots of children use the straight edge of the protractor instead of the line). Make sure that your line goes through 0 °.

 

2. Make a small mark on your paper to show where 180° is. If you want to, you could even draw a faint line to show the 180° line.

3.You now need to measure the remainder. Using the outside scale on your protractor, measure the angle from the 180° line you have drawn to the second line you have been given (in this case y to x).

4. Add together 180° to the second measurement and this will be your reflex angle.

5. If you want to check your answer, measure the inside angle and check that the two measurements added together equal 360°.

What is Reflex Angle?

A reflex angle is an angle that lies between 180° and 360°. A reflex angle and the corresponding angle that lies on the other side of it together form a complete angle of 360°. Observe the following figure to see what a reflex angle looks like.

Reflex Angle Definition

A reflex angle is always greater than a straight angle which is a half-circle (180°), and less than a complete angle which is a full circle (360°). It should be noted that a reflex angle always has an acute angle, an obtuse angle, or a right angle on the other side of it.

Reflex Angle Degrees

We know that a reflex angle and its corresponding angle add up to 360°. Therefore, the degrees of a reflex angle can be easily calculated. For example, if an acute angle measures 56°, then its corresponding reflex angle will be 360° — 56° = 304°. Similarly, if an obtuse angle measures 97°, then its corresponding reflex angle will be 360° — 97° = 263°.

Reflex Angle Picture

When two lines intersect at a point, the measure of the “opening” between these two lines is called an angle. Let us take the letters A, B, and O to name the angle. Observe the following figure to see the reflex angle which is the larger angle, and the smaller angle is an acute angle. It is to avoid this particular ambiguity that we refer to the angle marked outside as reflex ∠AOB.

Note: Reflex ∠AOB and the acute ∠AOB form a complete angle, therefore, they sum up to 360°.

How to Measure a Reflex Angle?

We know that with the help of a protractor we can easily measure any type of angle. Let us learn how to measure a reflex angle using the following steps. Observe the following figure to relate to the steps.

  • Step 1: Measure the internal angle with the help of a protractor. Here, we measure the internal angle as 110°.
  • Step 2: Subtract the value of this angle from 360° to get the value of the corresponding reflex angle. This gives us 360° — 110° = 250°.
  • Step 3: Therefore, the reflex angle is measured as 250° as seen in the figure.

Reflex Angle Examples in Real Life

We can easily notice reflex angles all around us in real life. Here is a list of a few examples of reflex angles that we come across in our day-to-day lives.

  • Clock: If we observe the hands of a clock at 7 o’clock, one side of the clock forms an obtuse angle. This is the side that falls on the side of the numbers 7, 8, 9, 10, 11, 12 marked in the clock. Now, the other side which has the numbers 1, 2, 3, 4, 5, 6, forms the reflex angle.
  • Pizza: In a circular pizza, if we cut a small slice and remove it, then the remaining part of the pizza forms a reflex angle.

Reflex Angle Examples

  1. Example 1: If angle AOB = 57°, what is the size of reflex angle AOB.

    Solution: A reflex angle and its corresponding angle always add up to 360°. Therefore, reflex angle AOB = 360° − 57° = 303°.

  2. Example 2: Using the properties of reflex angles, write true or false for the following statements.

    a.) A reflex angle is an angle that is more than 180° and less than 360°.

    b.) 170° is a reflex angle.

    Solution:

    a.) True, a reflex angle is an angle that is more than 180° and less than 360°.

    b.) False, 170° is an obtuse angle, not a reflex angle because it is less than 180°.

  3. Example 3: Which of the following is a reflex angle?

    a) 135°

    b) 40°

    c) 270°

    Solution:


    Out of the given options, c) 270° is a reflex angle as it lies in the range of 180° < reflex angle < 360°. Option a) 135° is an obtuse angle and option b) 40° is an acute angle. Therefore, the answer is option c) 270°.

FAQs on Reflex Angle

What is a Reflex Angle in Geometry?

An angle whose measure is greater than 180° but less than 360° is termed as a reflex angle. It is the angle that lies on the opposite side of any given acute, obtuse, and right angle. A reflex angle and its corresponding angle together form a complete angle of 360°.

What are the Examples of Reflex Angle?

All the angles that are more than 180° and less than 360° are called reflex angles. For example, 182°, 210°, 310°, and so on are reflex angles. Note that 180º and 360º are not reflex angles as they are straight angles and complete angles respectively.

What is the Difference Between an Obtuse Angle and a Reflex angle?

An obtuse angle is an angle that is more than 90° but less than 180°. A reflex angle is an angle that is more than 180° and less than 360°. So, a reflex angle is larger in size than an obtuse angle.

Is 180 Degrees a Reflex Angle?

No, 180 degrees is not a reflex angle. It is a straight angle. When the arms of an angle lie in the opposite direction, they form a straight angle of 180°. These arms make a straight line through the vertex. It is one-half of the whole turn of a circle and is called a straight angle because it looks like a straight line.

What is the Measure of Reflex Angle?

A reflex angle is more than 180° and less than 360°. In other words, a reflex angle lies between 180° and 360°.

How to Draw a Reflex Angle?

In order to draw a reflex angle, we can use the following steps. For example, let us draw a reflex angle of 240°.

  • Step 1: Subtract the given reflex angle from 360°. In this case, it gives us 360° — 240° = 120°.
  • Step 2: Draw and mark this angle using the protractor. Here, we need to draw an angle of 120° in the usual way.
  • Step 3: After marking this angle, the angle that we get on the outside is the required angle of 240°. This is because 240° + 120° = 360° which makes a complete angle.

Can a Triangle have a Reflex Angle?

No, a triangle cannot have a reflex angle. Since the interior angles of a triangle sum up to 180°, and we know that a reflex angle measures more than 180° and less than 360°. Therefore, it is not possible for one of its angles to be a reflex angle.

Can a Quadrilateral have a Reflex Angle?

Yes, a concave quadrilateral can have one of its angles as a reflex angle. However, a convex quadrilateral cannot have a reflex angle, that is, all its interior angles are less than 180°.

How to Find a Reflex Angle?

The value of a reflex angle can be easily found if the other side of the reflex angle is known. For example, if we need to find the reflex angle of 130°, we just need to subtract it from 360°. This gives us 360° — 130° = 230°. Therefore, the reflex angle of 130° is 230° because they form a complete angle together, that is, they sum up to 360°.

What does a Reflex Angle Look Like?

A reflex angle looks like an angle greater than a semicircle. In a 2D shape, the vertex with a reflex angle points inwards. Such shapes are known as concave figures.

Misconceptions related to bicycles / Habr

The article is intended for those who are just about to get on a bike and those who ride, but not very much, for their own pleasure, just to warm up or to move to the country, fishing, work.

Bicycle type

And the first question that arises: what bike layout to choose? Usually they buy something like this, that is, the so-called mountain bikes or road bikes:

But is this choice always the right one?

For those who are not involved in professional sports, I suggest taking a closer look at classic bikes.


In our country, they are now perceived as a relic of the Soviet past, regardless of in which country and when they were released. Looking at them, many see something like this:

A real and modern bike can only be sports. In fact, most of the bikes that we see on the roads, in parks and in nature only look like sports bikes, but they are not. These are fake sports bikes. Suffice it to recall not hardened bearings, constantly bending bushings and bursting tires, even with a short service life. But let’s not get ahead of ourselves, but let’s see what they drive abroad.

Berlin

Amsterdam

Copenhagen

Beijing 9 0020

Münster — Germany

Japan

Pay attention to the number of bicycles and how many of them are sports. Moreover, most of the owners of these bicycles also have expensive cars, but do not consider it shameful to pedal.

I want to draw an analogy with cars. Sports cars have a number of design features aimed at achieving greater speed. This is a rigid suspension, rear-wheel drive, etc., which turn into minuses during normal driving, the cross-country ability decreases, road bumps are dampened worse, and overall comfort suffers. It’s the same with cycling. Look at these pictures.


To reduce resistance to air flow, a person on a sports bike is almost horizontal, bending down to the handlebars. The saddle is raised much higher than the steering wheel, and the steering wheel itself is pushed forward. This posture cannot be called physiological. The load on the arms, back, neck increases. The center of gravity shifts forward. Athletes are accustomed people, but ordinary mortals get tired quickly. To somehow fix this, they lower the saddle and ride already on half-bent legs. If you don’t know what it is, then try to squat or half-crouch for a hundred meters. A small digression for beginners. The foot on the pedal, which is in the lower position, should be completely straight. If you, sitting on a bicycle, confidently reach the toes of both feet to the ground, then you need to raise the saddle and do not be afraid to get off the ground. This is a very important point!

It is more comfortable to sit when the handlebars are higher than the saddle. In this case, you will not lose much in speed. Unfortunately, on sports bikes, the handlebar height is not adjustable or slightly adjustable. Therefore, it is difficult to adjust the bike to your height.

Saddle

On sports bikes, it is quite rigid, narrow, with a thin layer of foam rubber and any absence of shock-absorbing springs. Of course, it’s not very comfortable to sit like that. Sometimes you can see how the owners of «mountain» bikes are afraid to call on the smoothest path. What can we say about mountain steeps and off-road?! To correct this problem, women and men pump silicone into their buttocks. It means that they wear special shorts with silicone inserts. Sports shops sell foam saddle pads, but they don’t help at all. Road bikes use wide seats with good cushioning and a thick layer of foam rubber. On such a saddle, one can easily fly a hundred kilometers.

Suspension fork

At first glance, a great thing, it allows you to hide the bumps in the road, it is easy to climb curbs. But there is one annoying thing here. When descending a hill, when the front wheel gets into even a small hole or a bump, the bike sends you somersaulting over the handlebars and the softer the springs, the more dangerous. Here, of course, there is also the fault of the low-set steering wheel, which is shifted forward, which shifts the center of gravity of the cyclist. To prevent this from happening or in case of failure of the springs, professionals replace them in the fork with reinforced rubber hoses.

Tires

Tires with deep tread look very impressive. Something like this:

It bites into the ground perfectly, but on asphalt it loses speed because of it. It’s like driving on square wheels. The difference is clearly visible when two cyclists go down a gentle hill without pedaling. One bike has deep tread wheels, the other has smoother tread. Professionals often have two types of tires and change them before the race, depending on the type of road. If you are going to ride primarily on asphalt, then choose tires with a smoother tread.

Women’s bike

This is how he used to be.

This is due to the fact that women traveled in skirts or dresses. Naturally, it would be indecent to throw the leg high because of the frame, and the asterisk needed better protection so as not to wind the hem of the dress. These problems are now a thing of the past. The fair sex puts on shorts or pants, but cunning marketers still try to convince us that a bike for women should be structurally different. Allegedly, this is due to the different anatomy of men and women: the hip is shorter, the little finger on the leg is longer, and so on. The frame is made a little shorter, the top bar is lowered lower, just as they did before, the springs on the fork are softer, the bikes themselves are smaller. Chasing after ghostly, barely perceptible features, manufacturers forget about the main difference between people and bicycles — this is growth. As in men’s bicycles, the handlebars are not height adjustable or adjustable, but within a small range. As a result, it will be even easier to fly over the steering wheel, going down the hill. It becomes harder for tall girls to pick up a bike because manufacturers believe that all the fair sex is shorter than men.

Wings

For sports bikes, this detail is considered optional, more decorative, they easily fall off and poorly fulfill their purpose — to protect the cyclist from splashes so that the back, trousers, and shoes are not stained with mud. If you leave in dry weather, this does not mean that you will not come across a puddle that cannot be bypassed.

Gearshift

A very good thing, allows you to pick up crazy speeds and overcome steep climbs. It just needs to be used correctly. Unlike a car, where you always have to start from first, then switch to second, etc., on a bicycle you do not need to constantly change speeds. Downshifts are needed only for climbing hills in order to win in power — to make it easier for yourself to climb, but to lose in speed. You can often see cyclists riding on a horizontal plane, pedaling hard, but moving slowly. If you turn the pedals with your feet, which do not meet resistance at all, then a lot of strength is still expended. Therefore, such a ride would be irrational.

Road bikes can also be equipped with gear shifting. Is it possible to go somewhere on a bicycle that has only one speed? According to the established public opinion — no, it is impossible. Actually it is not. You can safely drive to the nearest town, provided that there are no large elevation changes along the way. Also, do not think that if the bike is not “fast”, then you cannot ride it fast. You can’t go into the afterburner mode on it, but you can drive very quickly. Ultimately, a lot depends on the cyclist himself. I have repeatedly witnessed how the owners of a “sports” bike dragged their “iron horse” into a trolleybus and thus overcame hills, and other people on road bikes at the same speed drove the same hills on their wheels without any problems; how experienced cyclists on high-speed sports bikes constantly ride only at the speed of a retired summer resident and even at that speed they quickly run out of steam.

Equipment and accessories

Cycling clothes, on-board computer, etc. First, I’ll give an anecdote: “I really want to go for a run, but I don’t have a fitness bracelet or a smart watch.” The computer provides a lot of entertaining information about what the current speed is, how many kilometers have been covered, how many calories have been burned, how many cakes you can eat, but it is quite possible to do without it.

If you want to look fashionable and stylish, then buy special clothes — T-shirts, shorts, etc. Otherwise, a regular tracksuit with narrow legs and sneakers will suit you. But fingerless gloves are a convenient thing — it allows you not to rub your palms.

Again, I want to repeat that we are not talking about professional athletes, but only about those people who ride for their own pleasure.

Helmet. Safety is a good thing, but if you want to really improve your chances, then avoid roads with heavy traffic. It is better to ride on sidewalks, although this is against the rules of the road. A fast-moving truck or tour bus simply blows the bike away with airflow. There is a small category of drivers who treat cyclists like birds — if they need to, they will leave the road themselves, and if not, then this is their problem. Although in my subjective opinion: a bicycle is not a motorcycle, a helmet is not required for a cyclist.

Many girls consider a basket on the handlebars to be an indispensable attribute of a bicycle. In no case do not put anything in it and it is better to unscrew it immediately. Even a small load, such as a bottle of water, with a sharp turn of the steering wheel, begins to beat against the walls of the basket. Thus, the position of the steering wheel may change. This is especially fraught if you turned sharply due to a suddenly appeared car. It is better to put all the necessary cargo in a backpack.

Driving at night, especially on the roadway without front and rear lights, when you yourself do not see anything, and they do not see you, is pure suicide. Therefore, flashlights may be needed.

When you buy a bike, shop assistants will convince you that all cycling equipment is simply necessary, but the main thing is that the total cost of the entire purchase should not scare you away from buying the bike itself. What is really needed is the keys, pump, oil, camera repair kit and that’s it. By the way, at home it is more convenient to use not the set of keys that are sold in bicycle shops, but the usual ones. And yet, road bikes are much cheaper than sport bikes.

Virtual Reality

Someone instead of vast expanses, fresh air and speed prefers stuffy fitness rooms, exercise bikes, a TV on the wall that shows landscapes as if you were driving along the road — that is, an expensive imitation of a bicycle ride. A bicycle can give you not only lost kilograms of fat, but a sense of speed, unity with the wind, exciting journeys, cheerfulness and lightness.

Total

If you are not a professional athlete, but like to ride or go to work, fishing, etc. , then buy not sports bikes and fakes for them, but ordinary classic road bikes. They will be more comfortable, safer and more convenient for you.

It’s like riding a bike If the above information is useful to someone and helps save time, so much the better. If something is wrong — well, nobody’s perfect…

Comments / suggestions / constructive criticism — certainly welcome.

Cycling is the art of balance. A sense of balance is given to all of us by nature itself, it remains just to extend it beyond the body, onto a bicycle. And you need to do it carefully — the first experience is the most important. This undoubtedly pleasant and useful skill is most easily acquired in childhood. A child is literally easier (it’s not easy to maintain an adult in an unstable balance on a bicycle), and it’s easier to train. Less risk of injury from falls.

It would seem that wisdom is not great…

So it is!

Bicycle balance depends on the following factors:
— the angle of inclination of the NE relative to the vertical,
— steering angle,
— turning radius,
— speeds,
— weights CB,
— the type of track coverage, i. e. friction force, and especially from its uniformity,
— wind speed and direction,
— presence of obstacles and their type,
— add your choice.

The factors are interconnected, and when beyond the limits, the result is predictably painful.
But we will not tell the child all this. Nothing to complicate.

Fortunately, the child is still able to learn to ride intuitively.

I’m not much of an artist, I found an animation on the connection between steering wheel turning and tilt

In view of the approaching holidays, I propose to devote time to teaching your child.

You will need:

1. Child. Yours or any child who trusts and trusts you enough. Not all children are the same. Somehow, from the start, one boy began to pedal intensively, while randomly turning the steering wheel and deflecting his center of gravity. But. Almost all children can be taught to stay in the saddle. The main thing is to try to drop them as little as possible; trust is a fragile thing. Watch for when your child loses interest or becomes afraid. Take breaks. Ask for the child’s opinion. Do not be distructed. He’s the main one here.

2. Bicycle. It is more difficult here — not everyone will do. Which one do you think is better?

And in my opinion — like this:

Advantages of a balance bike over a «children’s bike» in training:

  1. Minimalism — weight, height, design — nothing distracts from the learning process.
  2. The child feels much more confident without losing contact with the ground. You can always lean on one or two legs, quickly stop, thanks to the low weight and inertia. And most importantly, it does not lose a sense of balance, which greatly simplifies the learning process.

In fact, a child who has just learned to run can ride a balance bike.

When riding a bicycle, the legs do not reach the ground and the balance has to be maintained consciously by tilting the center of gravity and turning the steering wheel.

A balance bike, by the way, can be made from a bicycle. It is enough to remove the excess — pedals / connecting rods / axle / chain (at the same time you will learn a lot about the design of the «children’s bike»). The difficulty is rather psychological — “how to break a working bike?” If everything goes according to plan, soon everything will need to be put back together — the child will be ready to move from a balance bike to a bicycle.

There is a nuance — with the saddle lowered as much as possible, the child should reach the floor well with his feet, otherwise the alteration does not make sense.

While a balance bike can make learning to ride a bike much easier, reduce your time and effort, you can still learn on a bike right away.

Bicycle

Remove those horrible extra wheels. With them, the bike turns into a stool. Learning to ride with them is the worst thing you can do. It’s like learning to fly while being tied to a kite: formally, you fly, but you don’t control the process and you don’t learn. The wheels slow down the movement, but do not give a feeling of complete stability — there is still a gap of a couple of centimeters, the bike sways and the child, falling from side to side, constantly feels discomfort and is in anticipation of a fall.

Design… All these ruffles were invented by adult uncles and aunts. A heavy frame welded from water pipes and painted with a pretty pink paint. Bicycle layout. Sometimes with a front and rear brake mockup and even a derailleur mockup. All this does not work, and cannot, because. children’s bikes are usually equipped with below lower grade attachments and only the price of the bike is similar to the real thing. Bearings? No, we haven’t heard.
High-quality children’s bicycles are scarce and expensive. For example, Specialized makes light, high-quality children’s bicycles, but their price may surprise you unpleasantly. In addition, the child quickly grows out of the bicycle, and it is expensive to buy a “firm” every year or two. On the other hand, almost everything that is sold under the guise of children’s bicycles is, at best, only superficially.

What you want:

  1. Lightweight frame (Specialized). A light bike is needed if the child can take out / bring in the bike himself (1st floor or private house). Usually, the bikes are taken out by the parents, which drastically reduces the number of trips the child has to make.
  2. Brakes. It is desirable that the front brake works well — it is more effective than the rear, and due to the low weight, low landing and low speed, the child has little chance of rolling over the steering wheel. Rear brake is optional. The brake in the hub (reverse pedal travel) is harmful — it distracts from maintaining balance and acts more slowly than the front one, because. the pedals must be in a certain position so that the brake can be applied. But usually it is.
  3. High-quality rubber is not needed / expensive. The child does not blow rubber — not the mileage, and most likely will not drive through mud / thorns / glass. The main thing is not to descend too quickly, otherwise parents will have to pump up before each use. And yes, do not be too lazy to check / pump up — the more the tires are inflated (especially the rear), the easier and more fun it is to ride (but without fanaticism).
  4. Helmet. I think it’s redundant, except that you will teach the child right away downhill

  5. Mudguards/Step/Flashlight/Reflectors/Rack/Bag — Optional. Most likely, you will not ride at night or in the rain. The lighter it is, the less weight to bring / take out for a walk.

Alternatively, take a look at used deals. The same Specialized from Europe costs an order of magnitude cheaper than a new one, but a used one, but previously bought new in our stores, is only 50% cheaper.

During the use of one child, the life of the bike does not suffer in any way. Maximum scratches. Do not be afraid to scratch the bike and do not scold the child for this — you will only discourage him from touching the bike.

It is impossible to bend/break the frame of a children’s bike — due to its miniature proportions and low load, it has an enormous margin of safety. Here I mean Bicycles; their 1:1 scale models will continue to stand beautifully on supermarket shelves. If you are unlucky, and relatives gave the child such a layout for his birthday, do not be discouraged. You can also ride it, though not so easily and quickly. But in a year or two you will know exactly what to look for.

You can also rent a bike, but keep in mind that the activity is unlikely to last more than half an hour, so it’s best to borrow from friends/neighbors first. When learning on a balance bike, several lessons for two days will be enough for the child so that you can no longer keep up with him. Then it will take a couple more days on the bike to fully get used to self-driving. If you learn right away on a bicycle, get ready to support the child for a week until he is no longer afraid of falling.

(Not) Falling, by the way, also needs to be taught. Choose a suitable place, away from the curbs, preferably on the ground. It is desirable that the bicycle frame be understated — it is easier both physiologically and psychologically. Make sure to hold the child with the bike when leaning/falling — you will probably need to simultaneously hold the saddle with one hand, the handlebars with the other, leaning slightly towards the bike and propping up with your feet. Accelerate, ask the child to slow down by braking, put out his left foot, help tilt the bike to the left and stop completely. Repeat to the right. Show that you can stop by resting your foot on the curb to maintain an upright position; without getting off the bike, rest and continue moving.

Make sure the bike/balance bike is in good working order: try loading the frame, you can kneel on the saddle or even squat down a bit – if the bike hasn’t broken under you, it means that the child will definitely be able to handle it. Check that the wheels turn easily and freely, the tires are inflated. otherwise the ride will be much harder and less interesting. Check that the brake is working. The stroke of the brake handle should be small (under a small child’s hand), braking should gradually increase as you press the handle and almost block the wheel at the end of pressing. You can start!

Your task is to help the child maintain balance, while holding the child as low and as symmetrical as possible, ideally by the center of gravity of the child-bicycle system, this is somewhere in the lower back area. Definitely not driving! Too high and asymmetrical, your influence on the center of gravity is too great. You can hold the bottom of the seat, but then you have to bend over, and this is inconvenient (especially running half-bent). As an option — a «parent handle» attached to the seatpost. Another option is to hold the child by the clothes from behind — just so as not to slip out, or fasten the father’s belt under the armpits of the child and support it by the belt.

It is necessary to support, i. e. to insure against falling, but giving the child enough freedom to manipulate his center of gravity — so he will quickly learn to maintain balance.
The higher the speed and the sharper the turn, the stronger the lean towards the turn.

First, to move forward, push the bike slightly, later, after mastering the balance, the child should pedal himself.

The next step is to find a suitable track. A horizontal section of smooth asphalt, at least 3 meters wide and 6 meters long. Preferably without high curbs and other obstacles. Preferably without pedestrians. Certainly not on the road. Park / courtyard / wide sidewalk … A wide area is needed for learning to turn — so the child will learn to balance much faster than being towed in a straight line. It is convenient to install a disposable cup with a pebble at the beginning and end of the site (for weighting, so that the wind does not blow away). The cups will show the child (and passers-by) the flight plan.

Tell the child that you are planning a smooth left turn in a wide arc. Tilt the bike slightly to the left while simultaneously turning the handlebars slightly to the left and make a 180 degree turn around the intended point (cup) with a smooth exit to a straight line. Then the same to the right. Allow the child to adjust the position of the center of gravity and turn the steering wheel a little, show that maintaining balance depends on these two factors (and also on speed, but this is not important now). Support minimally, trying not to interfere with the child’s attempts to control the bike, reducing only sharp jerks of the steering wheel and tilt, but always be ready to support the weight of the child and the bike, not to let the child fall.

If there are passers-by on the sidewalk — choose the moments for movement while the sidewalk is free, when it is busy — you can relax and explain to the child the plan for the next stage. After the start of the stage, the fewer distractions, the more effective the training. And verbal skirmishes with pedestrians who believe that the sidewalk is made for them (and they are right!) Can ruin your mood, and most importantly, your child. Therefore, be mutually polite on the chosen sidewalk.

Balance bike program

  1. Seat lowered to minimum. We go on foot, without sitting down, we steer a little to the right / left.
  2. Saddle up. Sit down, walk, drive, accelerate, brake (brake or kick)
  3. With support, we try to steer more actively, make wide smooth circles to the right / left.
  4. Learning to accelerate strongly, drive by inertia and brake.
  5. Learning to make 180/360 degree turns to the right/left only on momentum without touching the ground with your feet

Bicycle program

If a child already has experience of driving a balance bike, he will only have to transfer the existing experience of maintaining balance and add the skill of maintaining speed by pedaling

0. The child independently drives a bicycle, holding the steering wheel with both hands, the child is on the left. Let’s try to slow down. Show your child that an upright bike is easier to ride than a tilted one.

1. Sit down, sit down, get used to the saddle. We drive slowly.

2. Let’s move. We are steering. We spin the pedals. We drive a little faster

3. We try to slow down. We go, pause, repeat several times, gradually increasing acceleration. To begin with, there is only one brake — so as not to overload the child with information, preferably the front one, as the most effective.

3. With support, we try to steer more actively, make wide smooth circles to the right / left.

4. Learn to accelerate strongly, drive by inertia and brake.

5. Learning to make turns to the right/left by 180/360 degrees only on inertia.

6. Gradually reduce the firmness of the hold, giving the child more freedom.

7. Learning how to get on and off the bike on your own. Depends on the frame of the bike.
If it is high, holding the steering wheel with both hands, put your left foot on the pedal, slightly push off with your right and throw it through the frame. The child needs to both maintain balance and quickly start pedaling so as not to stop and fall. This is the most traumatic moment at this stage. While supporting the child, repeat as many times as necessary to make it comfortable for him to sit down / stand up on his own.

8. Raise the saddle so that the child’s legs are almost straight, passing the bottom point when pedaling. At this point, the child should be able to confidently get on / off the bike and not be afraid to fall.

9. Teach your child how to use the speed switch, independently selecting the speed depending on the descent / ascent / wind in such a way as to maintain a constant comfortable cadence (cadence). This will allow the child to move fast enough and far enough without making excessive efforts and without getting tired.

10. Get up on the move, moving by inertia. Repeat, trying to pedal while standing

11. Carefully try to overcome potholes and small curbs by standing up and using half-bent legs to soften the bumpiness. Somewhere here you can add a helmet to the equipment.

12. We complicate the track by overcoming several small obstacles at once. To do this, you need a margin of inertia, because. it is difficult to bounce and pedal with your feet at the same time, and lack / excess of inertia is fraught with a fall.

The next stage is skating together. The child will quickly learn to drive faster than you walk, and some of you will have to constantly wait or catch up, or wind circles if the track is convenient enough for this. It’s better to ride bikes together. You are behind to see the child, but he must know exactly where to stop (crossroads and other obstacles). We need a long sidewalk / bike path a couple of kilometers long. In the second case, tell the child that he should move in the right lane and stick to it yourself. Don’t make left turns without making sure it’s safe. If you need to stop, make sure you don’t block the path. There are already enough blockers — lines of pedestrians, mothers with strollers two or three, a bunch of students from countries with left-hand traffic who have rented bicycles, skiers with sticks .
