Scrolling Pedals On A Bicycle What To Do

Why pedals on a bicycle?

So why does the bike pedal and does not move? As a rule, this is caused by irregular or improper maintenance of the vehicle. Therefore, in the process of operation, the wear of entire groups of parts occurs, causing the breakdown of the bike.

Why is this happening?

When idling the pedals, pay attention to the following points:

  • Whether the chain has fallen into disrepair;
  • What is the state of the cranks of the stars;
  • Rear ratchet elements not damaged;
  • Whether the rear wheel hub is worn out;
  • Is the gearshift system configured correctly?

Failed parts should first be assessed for contamination. Perhaps they should simply be cleaned thoroughly to fix the problem. If some parts of the bike are worn out, then replacement is necessary here.

Chain problems

When the movement of the bike is accompanied by squeaking sounds and great effort is exerted while riding, it is necessary to assess the condition of the chain. When cranking the pedals, the following circuit problems and their elimination are possible:

  • Contamination: it is necessary, after removing the rear wheel and dismantling the chain, wash the links with soapy water and treat each with silicone grease;
  • Stretched chain: must be replaced, or self-shortened, when a special latch on a certain link is disengaged and the required number of links is removed, the sleeve from which is knocked out with a hammer, then the chain is also connected;
  • Chain links wear: some parts can be bent;
  • Severe damage to the chain: in this case, not only this part must be replaced, but also the stars, and possibly the entire transmission.

The problem is the cranks of the stars

The condition of the sprockets should be assessed when pedaling on mountain bikes, since the peculiarities of riding on such means involve excessive pedaling. Strong friction causes the jag to rub off or “lick”. What to do in this case?

First you need to remove the dirt by brushing the stars and the teeth of the stars with kerosene. Too licked teeth can be tried to sharpen, but it is not always possible to do it efficiently. If they are thinned, you cannot do without replacing the sprockets. The best solution would be to replace the entire kit. If there is no financial opportunity, changing speeds on a bicycle, identify and replace a failed sprocket.

Rear ratchet

When the pedals are scrolling, often the reason lies in the rear cassette. To deal with the problem, the ratchet should be dismantled and looked inside the mechanism.

If the problem is with the bearings. they are broken or part of them is missing, then the necessary balls should be filled.

We repair the bushing

When the hub fails, the wheel stops spinning and the bike’s pedals spin. The onset of wear of its elements leads to the fact that their engagement stops and the torque is not transmitted from the star to the hub. How to make a wheel spin?

To do this, remove the bushing by removing the cassette in mountain bikes. All elements must be inspected for wear: cone rollers, bearings and axle. Missing or damaged balls must be replaced.

If the rollers fail and the cone cannot engage with the bushing body, the inner part of the part rotates, and the outer part is motionless. As a result, the operation of the vehicle is disrupted. The cone can be sanded and the functionality of the bike can be extended for a short time. However, there will come a time when the sleeve will still need to be updated.

Malfunction in the speed switch

Another reason for pedaling can be a lack of shift detail to the correct sprocket. The problem may be that the cables are dirty or worn out. If damaged, they must be replaced by taking them out of the shirts. In the second case, rinse and return to shirts, avoiding excessive folds, so that no scuffs occur.

Before traveling long distances on a bike, it is necessary to study all the systems of the mechanisms. Then any breakdown can be quickly eliminated and your favorite vehicle can be brought back to life.

The pedals on the bike are scrolled. Pedals on a bicycle are scrolled: reasons, repair methods

Over time, every cyclist is faced with the problem of scrolling the crank-pedal assembly. This is due to insufficient maintenance of the bike, improper storage or untimely replacement of system parts.

To avoid spinning on the bike, it is enough to monitor the condition of the bike and inspect the parts for debris, lack of oil, or damage to a part. In some cases, scrolls do not require replacement of parts, only thorough cleaning with a rag with a special agent.

Why pedals on a bicycle?

Many cyclists face this problem. The mechanism that makes the bike move is called the crank-pedal assembly.

When a breakdown occurs, this group is checked first. For a full assessment of the degree of damage, it is necessary to disassemble the structure. After disassembly, you should determine the reason for the breakdown.

This could be influenced by several factors:

  • The chain of the bike was very stretched and subsequently deformed and now does not transfer movement to the rear sprockets. As a result, there is no movement, and the pedals move to idle.
  • The sprocket is worn so much that it does not transfer inertia to the wheel.
  • Critical damage to the rear wheel hub.

How to eliminate scrolling on a bike?

When spinning occurs on the bike, damage to one element may be permanent and should only be replaced.

Before determining what exactly the breakdown has occurred, you need to:

  • Unscrew the rear wheel, and then dismantle the transmission.
  • Take off the chain and sprocket.
  • Remove the rear wheel hub.
  • After that, you can proceed to inspect and identify a breakdown.

When checking the connecting rod-pedal assembly, first of all, pay attention:

  • Rear wheel hub (a very common problem on high-speed and road bikes, where, with constant use of this element, wear and tear occurs as a result of breakdown).
  • Bicycle chain (stretched or dirty).
  • Front sprockets (teeth worn out).
  • Ratchet in sprockets (teeth worn out).

Damage to sprocket cranks

On mountain (MTB) bikes, wear (licking) of the sprocket cranks often occurs as a result of constant and prolonged friction. It is not difficult to notice such a breakdown if the teeth become rounded or worn out. In this case, a complete replacement should be carried out.

With such a breakdown, the part cannot be repaired. The best option is to completely replace the sprocket chains, but this is quite expensive. If the teeth are intact, you can clean them from the remnants of oil, dust and other debris with a regular cloth dipped in kerosene.

Chain problems

Often the center of the problem is an old or worn chain.

If it has not been cleaned for a long time, then you need to clean it with a rag, kerosene and an old toothbrush to clean in inaccessible places.

After that, it is recommended to let the chain dry, and then lubricate with a special oil (based on silicone). You can prevent this situation if you hear a creak in advance or the pedals will start to scroll harder. In this case, the chain is preventively wiped.

There is another situation when the chain is too stretched.

This is determined by external examination:

  • If it hangs, then the reason is this. In this situation, it can be shortened.
  • To do this, you need to find a specific link on which the latch will be.
  • It fixes the ring connection. It must be removed.
  • To shorten the chain, you need to remove several links with a hammer by knocking out bushings from them.
  • After that, put the retainer back and put on the chain.
  • If after all the above operations nothing has changed, you need to change the chain to a new one.

Solving problems with rear ratchet

The rear ratchet could have affected the appearance of pedaling:

  • For this, the rear wheel is disassembled and the ratchet is inspected.
  • If it is overfilled with old oil or it is absent, corrosion has appeared, then the structure must be cleaned.
  • After that, dry and grease everything with a thick silicone-based oil.
  • If the ratchet is deformed or broken, replace it with a new one.

Bearing damage

Pedal scrolling can occur due to a lack of bearings in the hub. To verify this, you need to disassemble. If there are not enough steel balls, add the required amount.

Be careful when disassembling the bushing as the bearings may spill out. While the mechanism is disassembled, you can clean and lubricate all components.

Incorrect speed change setting

The last reason is incorrect bike speed setting.

This is due to the fact that the shifting foot does not reach the required sprocket:

  • To solve this problem, you first need to check the cable and clean it of dust and other debris, if any.
  • After that, you need to re-configure the gearshift system on the bike.
  • Having done all this, you need to conduct a test ride on a bike.
  • If the connecting rod-pedal group no longer scrolls, then the problem was precisely in this.
  • If there are no changes, the rest of the bike components must be checked.

What to do to avoid pedaling?

To reduce the possibility of the appearance of scrolling of the crank-pedal assembly, several rules must be followed.

Usually this breakdown occurs due to poor bike care:

  • Prompt attention to any changes in bike performance.
  • Several times a season or after each major ride, you need to disassemble and inspect all parts of the bike to determine wear.
  • If any parts are contaminated with dust, old oil or debris, they need to be cleaned.
  • It is recommended to check parts for oil.
  • If any corrosion, deformation or destruction is found, an urgent replacement of the part is required.

The service rules also include the peculiarities of bicycle storage. It is best to leave it indoors without constant and abrupt changes in climate, temperature, and to avoid high levels of moisture.

If the bike is stored unattended for a long time, you need to remove the chain (avoid stretching) and place it in a container with kerosene. You also need to loosen the brake system and remove, if possible, all electrical appliances.

The problem of scrolling the pedals of a bicycle most often occurs due to carelessness or careless handling of the bicycle. If a breakdown occurs, it is necessary to disassemble the parts that could cause this.

The pedals on the bike are spinning. the reasons and methods of fixing the problem

Bicycle pedaling is a common problem faced by every owner of this two-wheeled vehicle. The reason for this condition can be both worn out parts of the bicycle and improper care of the vehicle. This article will discuss the most likely causes of pedaling on a bike and how to solve the problem.

If the cranks of the bicycle sprocket are worn out

In general, problems with an asterisk can be detected with the naked eye without proper experience. First of all, you need to pay attention to the force with which you have to press on the pedals while driving. if you need to make significant efforts, then the problem is in the sprocket. And this leads not only to scrolling the pedals, but also to stretching the chain, and then there is only one way out. to completely replace the bicycle chain with a new one.

There are 2 more options:

  • The sprocket is simply “worn out” (licked off). this happens when the bike is used for a long time and in the absence of proper care of the vehicle. With this problem, poor grip is observed, which provokes pedaling.
  • The sprocket is too dirty. you will have to thoroughly clean it with special liquids or fine-grained sandpaper.

If there is a problem with a worn out asterisk, then you need to do the following:

  • remove the rear sprocket;
  • disassemble the asterisk;
  • if necessary, replace parts with new ones or sharpen the sprocket teeth.

Note: experienced cyclists recommend a complete replacement of the drive mechanism and have it done in a specialized workshop.

If there is a problem with the rear ratchet

The ratchet can malfunction if there is too much oil used to lubricate the ratchet, or, conversely, if there is no lubricant in this part of the bike. The ratchet bearings may even crumble or begin to stick. In any case, you will need to remove the ratchet and carefully inspect it. if necessary, replace the bearings, clean the parts from dirt and dust with special fluids, lubricate everything thoroughly. these simple manipulations can already eliminate pedal spin.

It is worth considering that before disassembling the ratchet and treating it with lubricants, it is worth looking at it under good lighting. you can immediately see how dirty the parts are and whether there is oil there. In this case, no disassembly / cleaning / lubrication work is necessary. look for another cause of the problem in question.

If there are problems with the transmission

Experienced experts believe that when scrolling the pedals, first of all, you need to pay attention to the transmission. it must be cleaned and thoroughly lubricated with special agents. Particular attention should be paid to the sprockets and the inter-roller space of the chain. To remove the chain for processing, you will have to dismantle the wheel.

If, even after cleaning the transmission, the pedaling problem persists, then it is advisable to completely replace the entire set.

You can repair or replace the rear hub. this will be a cardinal solution to the problem in question. We act as follows:

  • remove the wheel from the bike;
  • we carry out the spacing of the sleeve;
  • we inspect the axle and rollers of the cone, bushing bearings for the level of wear.

Note: some “craftsmen” give the cone for processing on a lathe. This approach to solving the problem can delay the cranking of the pedals, but sooner or later, the rear hub set will have to be replaced in any case.

Why pedals on a bicycle?

So why does the bike pedal and does not move? As a rule, this is caused by irregular or improper maintenance of the vehicle. Therefore, in the process of operation, the wear of entire groups of parts occurs, causing the breakdown of the bike.

Why is this happening?

When idling the pedals, pay attention to the following points:

  • Whether the chain has fallen into disrepair;
  • What is the state of the cranks of the stars;
  • Rear ratchet elements not damaged;
  • Whether the rear wheel hub is worn out;
  • Is the gearshift system configured correctly?

Failed parts should first be assessed for contamination. Perhaps they should simply be cleaned thoroughly to fix the problem. If some parts of the bike are worn out, then replacement is necessary here.

Chain problems

When the movement of the bike is accompanied by squeaking sounds and great effort is exerted while riding, it is necessary to assess the condition of the chain. When cranking the pedals, the following circuit problems and their elimination are possible:

  • Contamination: it is necessary, after removing the rear wheel and dismantling the chain, wash the links with soapy water and treat each with silicone grease;

  • Chain links wear: some parts can be bent;
  • Severe damage to the chain: in this case, not only this part must be replaced, but also the stars, and possibly the entire transmission.

The problem is the cranks of the stars

The condition of the sprockets should be assessed when pedaling on mountain bikes, since the peculiarities of riding on such means involve excessive pedaling. Strong friction causes the jag to rub off or “lick”. What to do in this case?

First you need to remove the dirt by brushing the stars and the teeth of the stars with kerosene. Too licked teeth can be tried to sharpen, but it is not always possible to do it efficiently. If they are thinned, you cannot do without replacing the sprockets. The best solution would be to replace the entire kit. If there is no financial opportunity, changing speeds on a bicycle, identify and replace a failed sprocket.

Rear ratchet

When the pedals are scrolling, often the reason lies in the rear cassette. To deal with the problem, the ratchet should be dismantled and looked inside the mechanism. Excessive oil density can cause the bearings to stick. It is also possible that liquid has entered the mechanism, or there is no oil at all, and everything inside is dirty and covered with rust. In these cases, the parts must be thoroughly cleaned and relubricated.

If the problem is with the bearings. they are broken or part of them is missing, then the necessary balls should be filled.

We repair the bushing

When the hub fails, the wheel stops spinning and the bike’s pedals spin. The onset of wear of its elements leads to the fact that their engagement stops and the torque is not transmitted from the star to the hub. How to make a wheel spin?

To do this, remove the bushing by removing the cassette in mountain bikes. All elements must be inspected for wear: cone rollers, bearings and axle. Missing or damaged balls must be replaced.

If the rollers fail and the cone cannot engage with the bushing body, the inner part of the part rotates, and the outer part is motionless. As a result, the operation of the vehicle is disrupted. The cone can be sanded and the functionality of the bike can be extended for a short time. However, there will come a time when the sleeve will still need to be updated.

Malfunction in the speed switch

Another reason for pedaling can be a lack of shift detail to the correct sprocket. The problem may be that the cables are dirty or worn out. If damaged, they must be replaced by taking them out of the shirts. In the second case, rinse and return to shirts, avoiding excessive folds, so that no scuffs occur. They should not be treated with oil, as the initial ease in gear shifting will turn into great difficulty when dirt sticks to the cables. Next, adjust the switch again and check if the wheel has started moving.

Before traveling long distances on a bike, it is necessary to study all the systems of the mechanisms. Then any breakdown can be quickly eliminated and your favorite vehicle can be brought back to life.

Causes of pedaling on a bicycle and their elimination

Why pedals on a bike? Most cycling enthusiasts face a similar problem. But even if you are a beginner and only recently purchased a bike, you should definitely know what the problem is, how to avoid it and what to do in such a situation.

Pedaling: what are the problems and what are the causes

If a malfunction occurs for the first time, it can be difficult to determine what exactly it is. Signs of a pedaling problem:

  • The wheel does not spin or does not spin enough;
  • The bike chain slips while riding;
  • Increase in freewheel.

In general, the reasons why the pedals on the bike are spinning are:

  • Worn bike sprocket cranks. There is no need to undergo a technical inspection to establish this reason: the problem is obvious. When worn, the cranks on the sprocket appear worn and worn. A similar problem can arise from natural causes: the bike is simply old enough and already worn out. Or, while riding, the cyclist exerts too much force by applying excessive pressure on the pedals.
  • Why does the rear sprocket spin on a bike? The reason may also lie in the lack of regular technical inspection and insufficient washing: perhaps the sprocket on the bicycle is simply dirty.
  • Chain problem, which is one of the most common. The reason, as in the case of the wear of the sprocket cranks, may lie in the old age of the bike and not in regular maintenance. Perhaps the chain just needs washing and sufficient lubrication;
  • Rear ratchet problems can be due to several reasons. Many people sin by using too much oil or grease with an increased thickness. This could cause the ratchet to malfunction. It can also be caused by dirt and dust mixed with oil, or a broken bearing.

Bicycle sprocket crank problems: what to do

Once you’ve identified the source of the problem. the cranks. and figured out the cause, you can start fixing it. The simplest case is sprocket contamination. Just rinse the parts thoroughly, wipe with a dry, lint-free cloth and let dry. Never lubricate parts wet! After thoroughly drying, you can lubricate with special oil. An important point: there should not be too much grease, otherwise it will again lead to malfunctions.

If the sprocket is “lapped”, then it must be removed, disassembled, cleaned of dirt. A worn sprocket may need to be replaced with a new one or its teeth sharpened. Even if the sprocket on the bike can be repaired, then it will not last long, so it is better to spend money on repairs right away. If you have never done anything like this before and you are worried about scrolling on the bike, repair is the best solution.

Solving rear ratchet and chain problems on your bike

As in the previous case, the ratchet must be thoroughly cleaned, dried and lubricated. perhaps this will be enough. If not, the wear problem of individual ratchet sprockets is solved by replacing them. In addition to sprockets for replacement at home, a key is purchased.

Lubricate the chain after cleaning it, you need to drip a drop onto each (this is important) link of the part. Look carefully to see if the chain has bent links. If so, then they must be carefully brought back to their original position. If the chain is stretched or worn too much, then it must be replaced with a new part.

In some cases, replacing a new chain does not solve the problem, and pedaling continues, since the new part is not “similar” enough to the old.

In this case, you need to either use the bike until the problem is solved on its own (the chain reaches a certain level of wear), or (which is preferable), replace the entire transmission in a repair shop. A transmission is the mechanism that sets a bicycle in motion. It includes sprockets, chain and cassette (rear sprockets).

What to do to avoid pedaling?

Avoid greases that are too thick or old.

As you can see, many problems with a bicycle, including pedaling, can be solved simply: often washing and lubricating the part is enough. But even if the reason lies in something more, the problem of scrolling is solved quite simply and everyone can do it. Do not forget to regularly wash and lubricate the “iron horse”, as well as regularly carry out maintenance, and your bike will delight you for a long time.

The pedals on the bike are scrolled. Why bicycle pedals spin and what to do about it

The connecting rod-pedal group is the very unit thanks to which the bicycle is set in motion. One of the problems why the bike does not ride well or does not move at all is pedaling. The problem arises unexpectedly, and what it is connected with is not easy to understand right away. What causes the pedals to spin, and how to fix it, will be discussed later in the article.

Why pedals are spinning idle

  • increase in free wheeling;
  • weak spinning of the wheel;
  • chain slippage in motion.

If a malfunction is detected, there is a keen desire to check the pedals, more precisely, the drive connecting rod-pedal mechanism. Some of the scrolling is due to the carriage, but often the reasons lie elsewhere in the drivetrain:

  • rear wheel hub;
  • sprocket system. cassette or ratchet;
  • chain and chainrings.

The first reason is common for road bikes, mountain bikes, and single-speed bikes with hub-drum brakes. With long-term operation, the inner components of the bushing wear out, lose their engagement with each other, due to which the torque from the sprocket is not transmitted to the bushing. As a result, the cyclist pedals only the stars, but not the wheel itself.

The pedals spin completely, and the wheel does not spin. a neglected case when the hub fails. But most often there is an increase in free travel, the bike starts to move harder, and slippage appears on the move.

READ  How to Choose a Bicycle Wheel Diameter

Cassettes and ratchets are fast bike parts. Full wear on cranks and bearings can cause chain slippage and idle pedaling. Other causes are partial wear, dirty sprockets, too much or no lubrication.

The chain is the same on singlespeeds and speed bikes, so wear and / or dirt can cause the pedals to crank in both. In the stretched state, the chain hooks on the teeth of the stars worse, sliding over them. Total link length ranges:

  • 304.8. 306.4 mm. normal chain;
  • 306.4. 308 mm. Average chain wear. May affect the transmission of torque, single pedal clicks are possible.
  • 308 mm and more. the chain is worn out, causes wear on the stars, slips and flies.

Worn chain sprockets, coupled with a worn chain, can also increase pedal cranking and bouncing. Although the problem may arise due to accumulated dirt.

Solving the problem on a regular bike

The first, and in some cases the surest, solution is to thoroughly clean and lubricate the transmission. Pay special attention to the sprockets and the inter-roller space of the chain. Before you clean the chain, you need to carefully dismantle it, and you cannot do without removing the rear wheel.

If after cleaning the problem persists, the wear of the chain and sprockets is high, you should consider replacing it. You need to install the kit immediately on the bike. The new chain will stretch quickly on the old sprockets, causing you to crank with renewed vigor.

Repair or replacement of the sleeve is a cardinal solution to the problem:

  • Remove the wheel from the bike.
  • Spread the sleeve.
  • Inspect bushing bearings, axle and taper rollers for wear.

When strong workings form on the arched surfaces of the part, the rollers fall through. As a result, the cone does not engage with the hub body. It turns out that the inner part of the bushing rotates, and the outer one stays in place or lags behind, increasing wear.

The sleeve can be returned to the workshop for cone grinding. This will delay pedal scrolling for a while, but wear will still make itself felt. There is only one conclusion. to change the part completely.

How to fix spinning on a speed bike

The main reason why pedals spin the wheel poorly on a high-speed bike is complete wear of the rear sprocket system. First, it is determined how dirty the system is and its degree of wear. How to clean a cassette:

  • Take off the bike.
  • Clean the space between the stars with a flat brush.
  • Wipe the teeth and washers with a cloth soaked in kerosene.

After thorough cleaning of dirt, check the condition of the bearings. Scattered or knocked out parts must be replaced. The condition of the stars plays an important role. worn out teeth indicate their unsuitability. This is especially true for small sprockets. here chain slip and pedal scrolling are more pronounced.

And finally, check the performance of the system using the speed switch: through which stars the chain slips, they must be replaced. After cleaning and partial replacement, the system is lubricated.

Rear hubs can also fail, the problem is the same as with a single speed bike. The cassette must be removed to access the bushing. The condition and position of the bearings, wear of the cone and roller tappets are carefully checked. If you suspect a bushing, it is recommended to install a new part.

When the pedals just spin, it’s a sure sign of transmission wear. To prevent the problem from turning into more unpleasant consequences, you should diagnose the bike in time and eliminate the malfunction.

  • If it is overfilled with old oil or it is absent, corrosion has appeared, then the structure must be cleaned.
  • After that, dry and grease everything with a thick silicone-based oil.
  • If the ratchet is deformed or broken, replace it with a new one.

Bearing damage

Pedal scrolling can occur due to a lack of bearings in the hub. To verify this, you need to disassemble. If there are not enough steel balls, add the required amount.

Be careful when disassembling the bushing as the bearings may spill out. While the mechanism is disassembled, you can clean and lubricate all components.

Incorrect speed change setting

The last reason is incorrect bike speed setting.

This is due to the fact that the shifting foot does not reach the required sprocket:

  • To solve this problem, you first need to check the cable and clean it of dust and other debris, if any.
  • After that, you need to re-configure the gearshift system on the bike.
  • Having done all this, you need to conduct a test ride on a bike.
  • If the connecting rod-pedal group no longer scrolls, then the problem was precisely in this.
  • If there are no changes, the rest of the bike components must be checked.

What to do to avoid pedaling?

To reduce the possibility of the appearance of scrolling of the crank-pedal assembly, several rules must be followed.

Usually this breakdown occurs due to poor bike care:

  • Prompt attention to any changes in bike performance.
  • Several times a season or after each major ride, you need to disassemble and inspect all parts of the bike to determine wear.
  • If any parts are contaminated with dust, old oil or debris, they need to be cleaned.
  • It is recommended to check parts for oil.
  • If any corrosion, deformation or destruction is found, an urgent replacement of the part is required.

The service rules also include the peculiarities of bicycle storage. It is best to leave it indoors without constant and abrupt changes in climate, temperature, and to avoid high levels of moisture.

If the bike is stored unattended for a long time, you need to remove the chain (avoid stretching) and place it in a container with kerosene. You also need to loosen the brake system and remove, if possible, all electrical appliances.

The problem of scrolling the pedals of a bicycle most often occurs due to carelessness or careless handling of the bicycle. If a breakdown occurs, it is necessary to disassemble the parts that could cause this.

The pedals on the bike are spinning. the reasons and methods of fixing the problem

Bicycle pedaling is a common problem faced by every owner of this two-wheeled vehicle. The reason for this condition can be both worn out parts of the bicycle and improper care of the vehicle. This article will discuss the most likely causes of pedaling on a bike and how to solve the problem.

If the cranks of the bicycle sprocket are worn out

In general, problems with an asterisk can be detected with the naked eye without proper experience. First of all, you need to pay attention to the force with which you have to press on the pedals while driving. if you need to make significant efforts, then the problem is in the sprocket. And this leads not only to scrolling the pedals, but also to stretching the chain, and then there is only one way out. to completely replace the bicycle chain with a new one.

There are 2 more options:

  • The sprocket is simply “worn out” (licked off). this happens when the bike is used for a long time and in the absence of proper care of the vehicle. With this problem, poor grip is observed, which provokes pedaling.
  • The sprocket is too dirty. you will have to thoroughly clean it with special liquids or fine-grained sandpaper.

If there is a problem with a worn out asterisk, then you need to do the following:

  • remove the rear sprocket;
  • disassemble the asterisk;
  • if necessary, replace parts with new ones or sharpen the sprocket teeth.

Note: experienced cyclists recommend a complete replacement of the drive mechanism and have it done in a specialized workshop.

If there is a problem with the rear ratchet

The ratchet can malfunction if there is too much oil used to lubricate the ratchet, or, conversely, if there is no lubricant in this part of the bike. The ratchet bearings may even crumble or begin to stick. In any case, you will need to remove the ratchet and carefully inspect it. if necessary, replace the bearings, clean the parts from dirt and dust with special fluids, lubricate everything thoroughly. these simple manipulations can already eliminate pedal spin.

It is worth considering that before disassembling the ratchet and treating it with lubricants, it is worth looking at it under good lighting. you can immediately see how dirty the parts are and whether there is oil there. In this case, no disassembly / cleaning / lubrication work is necessary. look for another cause of the problem in question.

If there are problems with the transmission

Experienced experts believe that when scrolling the pedals, first of all, you need to pay attention to the transmission. it must be cleaned and thoroughly lubricated with special agents. Particular attention should be paid to the sprockets and the inter-roller space of the chain. To remove the chain for processing, you will have to dismantle the wheel.

If, even after cleaning the transmission, the pedaling problem persists, then it is advisable to completely replace the entire set.

You can repair or replace the rear hub. this will be a cardinal solution to the problem in question. We act as follows:

  • remove the wheel from the bike;
  • we carry out the spacing of the sleeve;
  • we inspect the axle and rollers of the cone, bushing bearings for the level of wear.

Note: some “craftsmen” give the cone for processing on a lathe. This approach to solving the problem can delay the cranking of the pedals, but sooner or later, the rear hub set will have to be replaced in any case.

What to do if the pedal is unscrewed on a bicycle

Any more or less complex technical structure tends to break. There are many reasons for this fact. defective structural elements, poor-quality assembly of this bicycle assembly, wear of parts, and so on. Be that as it may, the question of what to do if the pedal is unscrewed on the bike puzzles the owner of the bike, faced with this fairly common problem. In addition to the discomfort caused by the constantly unscrewing pedal, the operation of a technically faulty bike is fraught with tragic consequences.

Therefore, it is necessary to quickly solve this problem and use the bike without worrying about your own safety. We will figure out what should be done so that the bicycle pedal does not unscrew, we will answer a number of related questions to this topic, and also give some relevant recommendations.

Types and structure of bicycle pedals

Before proceeding with self-repair, you need to get general information about the types and structure of this seemingly simple element of the bike. Conventionally, bicycle pedals are divided into ordinary (traditional) designs, contact ones designed for special shoes, as well as combined ones that combine both types. one plane is ordinary, the other is for special sneakers. All types are structurally almost the same and consist of the following elements:

  • the axis is the basis of the entire element, which is a pin made of metal, screwed into the connecting rod;
  • platform. a part directly in contact with the cyclist’s leg, attached to the axle;
  • bearings. elements that provide a movable (do not impede rotation) connection between the axle and the platform;
  • additional parts. bolts, nuts, guaranteeing reliable fixation of all components of the pedal.

Having received information about the structure of this element of the bicycle, you can proceed directly to the repair.

Solution to the problem

Most often, cyclists are faced with the fact that it is not the pedals themselves that are unscrewed, but the connecting rod itself. the lever that transfers the rotation energy to the system of stars and chains, forcing the bike to ride. This is due to a factory defect in rare cases, due to wear of parts, but more often due to poor-quality assembly after maintenance (lubrication of elements) or replacement of the unit. The play that occurs when riding on a loosely fixed connecting rod on the axle looses the fixing bolt, which, in turn, turns the square of the carriage into a more abstract figure. Ideally, replace the failed unit. However, if such an opportunity is not observed in the near future, and you want to ride a bike, you can fix the problem yourself.

Fantastic recipes are offered on various forums on the Web for solving the problem of unscrewing the pedal. up to the use of welding. Yes, it is possible to weld the connecting rod tightly, if it is metal, to the axle, and it really will never unscrew itself. But when the time comes to replace it, it will be possible to remove it only with the help of a “grinder”. It is much more effective and practical to use a thread lock. an anaerobic (curing without oxygen access) compound that functions like glue for metal. The process is as follows:

  • We carry out the disassembly of the “damaged” bicycle assembly using tools prepared in advance.
  • The carriage axis, the inner planes of the connecting rod, the thread of the bolt or nut (in cheaper designs) should be thoroughly cleaned of grease. To do this, you must have rags and a special mixture (can be replaced with ordinary kerosene).
  • Next, we assemble the assembly, but before tightening the bolt, apply a few drops of the retainer to the thread.

While the bolt is tightened, the composition is evenly distributed over the entire surface, gluing the elements together. As a result, the load, thanks to the retainer, is evenly distributed along the entire length of the thread, self-loosening is excluded, and reliable protection against the appearance of corrosion and rust appears.

A few words about the fixator

  • the red clamp has the highest strength indicator. it will not be possible to turn the pedal after its application (you will have to resort to the help of the same “grinder”);
  • the green retainer can be weak or high strength. depending on the manufacturer;
  • retainer blue or blue. medium strength.

On the market there are also purple fixatives with moderate strength and purple compounds with the lowest rates. To subsequently turn the pedal without applying titanic forces, use a blue or blue retainer.
