Simple solution to the problem
When the pedals begin to turn, you should not immediately think about repairs, start disassembling all the components and systems. If the pedals are scrolling on a high-speed bike, then it makes sense to first check the correct setting of the front and rear derailleurs, which are responsible for changing the speeds.

Creak Or Click? Six Ways To Fix Your Noisy Bike
On two-wheeled vehicles without a gearshift system, it may also turn out that to solve the problem, it is enough just to thoroughly clean the chain and lubricate it well.
What to do to avoid pedaling?
The most common cause of spinning on a bike is a chain malfunction.
Therefore, you should give her close attention and care in order to avoid possible problems. After each long ride (especially after driving in bad weather), thoroughly rinse the chain to remove dirt and excess lubricant.
Chain and Pedal Lubrication
Avoid greases that are too thick or old.
As you can see, many problems with a bicycle, including pedaling, can be solved simply: often it is enough to wash and lubricate the part. 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.
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 state of the stars plays an important role. worn teeth indicate their unsuitability. This is especially true for small sprockets. here chain slip and pedal scrolling are more pronounced.
Normal (left) and ground gear teeth
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 there is a clear suspicion of the 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 your chain goes off on a bike without gears, all you need to do is unscrew the two nuts on the rear wheel axle and then pull it towards you. Tighten the nuts, but make sure that the wheel does not move closer to the center of the frame. By following these steps, you will see that the chain will not sag. Accordingly, the likelihood that it flies again is completely excluded. But in the case of the occurrence of this problem on a high-speed bike, you will have to sweat. A special spring is installed in the gear selector, which automatically pulls the chain. With prolonged use, it loses its elasticity, which leads to similar problems. Since the transmission is not separable, you will have to change the switch to a new one.
Curvature of one or more links
Such a problem can be encountered quite rarely, but it can still bother you at any time. If you notice that the links are curved, you have two options. The first is to completely replace the chain. The second is to get rid of the bent links using a special squeeze. Do not use this method on bicycles without variable transmission. On models with gear derailleurs, it is recommended to use this method as a temporary solution.
Bike Clicking When Pedaling
Why does the chain slip on a bicycle under load
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 tangible 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.
- 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 maintenance 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.
experienced cyclists recommend a complete replacement of the drive mechanism and have it done in a specialized workshop.
Chain slips on a bicycle under load. reasons, tips for elimination
Any type of cycling will always have a significant impact on its drivetrain. Why is a chain slipping on a bicycle and how to fix the problem? The chain and stars will wear off or deform over time.
To prolong their life, regular maintenance is recommended in the form of cleaning from dirt and dust, and lubrication. But even if all the rules for caring for the transmission are followed, its parts will still wear out over time. Then their replacement is required.
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 with 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.
The stars can deform due to wear or mechanical damage resulting from impact. In both the first and second situations, it is impossible to restore the cassette teeth. Therefore, a replacement with a new one is required.
If there is a problem with the rear ratchet
The ratchet may 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 sprinkle, 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.
Honor should look at it under good lighting before disassembling the ratchet and lubricating it. 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.
Why does the chain slip on a bicycle
The first symptoms of transmission malfunction occur when shifting gears while depressing the pedals. Cyclists often notice this immediately when going uphill, because then the load on the bike is one of the strongest.
Reasons for chain slippage on a bicycle:
- stretching of the chain due to wear of its links (in particular, their thinning);
- wear of the sprockets;
- two reasons at the same time.
Both factors at the same time
Also, the chain can slip due to the stretched chain and wear of the sprockets at the same time. This regularity is due to the following: with a decrease in the distance between the chain rollers, the teeth of the sprockets also narrow at the same time. To determine the degree of wear, it is enough to compare the width of new and worn stars.
The reason for the one-time wear of the chain and sprockets is also incorrect gear shifting. This leads to a strong distortion of the chain, and some parts of the parts are under increased pressure, and they wear out faster.
If the calipers are incorrectly adjusted, spontaneous jumps of the stars occur, the chain comes off or it gets jammed. In this case, the cyclist may be injured, and therefore the calipers need to be adjusted and checked in all positions. If the chain is dirty, it can also slip. Elimination of the symptom. timely cleaning and lubrication of the components.
Why does the bike chain slip?
Chain overshoot causes one of two unrelated phenomena. direct overshoot and spontaneous gear shifting.
The main thing to solve the problem is to determine what exactly comes from the two cases. Chain bounce is when it bounces under load on the top of the sprocket teeth.
This happens very often when the chain is on the smallest star of the cassette, especially when it is used in conjunction with the smaller star of the system (which cannot be done). Also, sometimes overshoot can occur when the chain has bent links.
The sounds emitted while cycling can vary in quality. They can be roughly divided into:
Clicks are usually inevitable if you are driving on muddy roads and sandy trails. Grains of sand get into the clamping joints and begin to make themselves felt. Very rarely, but it also happens that cracks in the metal lead to clicks. To lubricate problem areas, it is best to use grease sticky compounds.
The knocking and grinding sound heard when the pedal is pressed firmly indicate that the part is running dry, there is no lubricant at all. The balls by this time become cubes or other geometric bodies. To check if this is so, you need to listen to the pedals at idle: you will hear a slight rustle of metal.
The whistle of the pedals can be like a series of short clicks, or more like the creak of foam on a glass surface. Any whistle signals that there is no lubricant in the rubbing unit. In rare cases, the cause of the sound can be an internal breakdown of the material itself, plastic or metal.
Sometimes a weak whistle occurs due to dust particles on the bushings. With such a “diagnosis”, a good result will be obtained by using liquid graphite lubricant.
If the pedals squeak
While riding, the pedal carriages may squeak loudly when they come into contact with the sole of the shoe. Dry friction is the cause of the characteristic squeak in most cases. It can be triggered by the following reasons:
- the thread in the connection with the connecting rod is too tight;
- the fasteners are slightly loosened, which leads to difficult movement of the parts of the platform relative to each other;
- grease is squeezed out of the bearings;
- particles of dirt, dust, sand and other things get into the gap;
- the bearing race collapses and is partially jammed.
Before starting the diagnosis, you should sit on the bike, press the right pedal, then the left pedal and rotate them. If a characteristic crunch or knock is heard from one side, the problem must be looked for in the pedal bearing.
As a rule, you can identify the problem by disassembling and reassembling the pedal for details several times. This will allow the threads to be ready for use. You should also check the fasteners and fix them as tightly as possible, if necessary. At the same time, you need to clean the pedal by removing drops of grease, small debris and sand. If these measures do not work, it remains to look for the cause inside the pedal mechanism.
Bicycle pedal knocking
A bicycle, like a beloved child, requires care and attention. To find out if your bike is “healthy” or “sick”, it is enough to listen to it while driving. Among the many sounds that can be considered absolutely normal (seat creaking, spokes chirping, quiet rustling of tires or the sound of a ratchet at idle speed), there are some that should immediately alert the owner. These, without a doubt, include the incessant, clearly distinguishable creak of mechanical components or the knock on the pedals of the bicycle. Even a novice rider should know what to do when such problems are encountered.
How to fix the situation
To overcome dry friction, due to which the bearings wear out and the pedal knocks, it is enough to use a high-quality grease. However, she will not be able to completely solve the problem. It is best to install a new part and not guess which part is damaged. For example, if a clip collapses, seat wear is almost always to blame. In this case, restoration may be more expensive than buying a new pedal, so it is easier to immediately purchase a part with a large resource.
In order to prevent surface wear, the lubricant should be changed after each prolonged sanding. The sand turns into an abrasive, which leads to a violation of the integrity of the surfaces. The creak in this case is also accompanied by a characteristic crunch.
With a sparing attitude to the bike and timely care for it, no trouble should happen. If the parts have become completely unusable, do not delay their replacement. Ride quality and personal safety are much more expensive.
